The Battle of the Coral Sea, from 4 to 8 May 1942, was a major naval battle between the Imperial Japanese Navy (IJN) and naval and air forces of the United States and Australia. Taking place in the Pacific Theatre of World War II, the battle was the first naval action in which the opposing fleets neither sighted nor fired upon one another, attacking over the horizon from aircraft carriers instead. It was also the first military battle between aircraft carriers.[9]

To strengthen their defensive position in the South Pacific, the Japanese decided to invade and occupy Port Moresby (in New Guinea) and Tulagi (in the southeastern Solomon Islands). The plan, Operation MO, involved several major units of Japan's Combined Fleet. Two fleet carriers and a light carrier were assigned to provide air cover for the invasion forces, under the overall command of Admiral Shigeyoshi Inoue. The U.S. learned of the Japanese plan through signals intelligence and sent two U.S. Navy carrier task forces and a joint Australian-American cruiser force to oppose the offensive, under the overall command of U.S. Admiral Frank J. Fletcher.

On 3–4 May, Japanese forces invaded and occupied Tulagi, although several supporting warships were sunk or damaged in a surprise attack by the U.S. carrier Yorktown. Alerted to the presence of enemy aircraft carriers, the Japanese fleet carriers advanced towards the Coral Sea to locate and destroy the Allied naval forces. On the evening of 6 May, the two carrier fleets closed to within 70 nmi (81 mi; 130 km) but did not detect each other in the darkness. The next day, both fleets launched airstrikes against what they thought were the enemy fleet carriers, but both sides actually attacked other targets. The U.S. sank the Japanese light carrier Shōhō, and the Japanese sank the destroyer Sims, and damaged the fleet oiler Neosho. On 8 May, both sides finally located and attacked the other's fleet carriers, leaving the Japanese fleet carrier Shōkaku damaged, the U.S. fleet carrier Lexington critically damaged and later scuttled, and the fleet carrier Yorktown lightly damaged.

Both sides having suffered heavy aircraft losses and carriers sunk or damaged, the two forces disengaged and retired from the area. Because of the loss of carrier air cover, Inoue also recalled the Port Moresby invasion fleet. Although the battle was a tactical victory for the Japanese in terms of ships sunk, it has been described as a strategic victory for the Allies. The battle marked the first time since the start of the war that a major Japanese advance had been turned back. More important, the damage to Shōkaku and the aircraft losses of Zuikaku prevented both ships from participating in the Battle of Midway the following month.

## Background

### Japanese expansion

[edit]

Japanese advances in the Southwest Pacific from December 1941 to April 1942

On 8 December 1941 (7 December U.S. time), Japan declared war on the U.S. and the British Empire, after Japanese forces attacked Malaya, Singapore and Hong Kong as well as the U.S. naval base at Pearl Harbor. In launching this war, Japanese leaders sought to neutralize the U.S. fleet, seize territory rich in natural resources, and obtain strategic military bases to defend their far-flung empire. In the words of the Imperial Japanese Navy (IJN) Combined Fleet's "Secret Order Number One", dated 1 November 1941, the goals of the initial Japanese campaigns in the impending war were to "[eject] British and American strength from the Netherlands Indies and the Philippines, [and] to establish a policy of autonomous self-sufficiency and economic independence."[10]

To support these goals, during the first few months of 1942, besides Malaya, Japanese forces attacked and took control of the Philippines, Singapore, the Dutch East Indies, Wake Island, New Britain, the Gilbert Islands and Guam, inflicting heavy losses on opposing Allied land, naval and air forces. Japan planned to use these conquered territories to establish a perimeter defense for its empire from which it expected to employ attritional tactics to defeat or exhaust any Allied counterattacks.[11]

Shortly after the war began, Japan's Naval General Staff recommended an invasion of Northern Australia to prevent Australia from being used as a base to threaten Japan's perimeter defences in the South Pacific. The Imperial Japanese Army (IJA) rejected the recommendation, stating that it did not have the forces or shipping capacity available to conduct such an operation. At the same time, Vice Admiral Shigeyoshi Inoue, commander of the IJN's Fourth Fleet (also called the South Seas Force) which consisted of most of the naval units in the South Pacific area, advocated the occupation of Tulagi in the southeastern Solomon Islands and Port Moresby in New Guinea, which would put Northern Australia within range of Japanese land-based aircraft. Inoue believed the capture and control of these locations would provide greater security and defensive depth for the major Japanese base at Rabaul on New Britain. The navy's general staff and the IJA accepted Inoue's proposal and promoted further operations, using these locations as supporting bases, to seize New Caledonia, Fiji, and Samoa and thereby cut the supply and communication lines between Australia and the United States.[12]

In April 1942, the army and navy developed a plan that was titled Operation MO. The plan called for Port Moresby to be invaded from the sea and secured by 10 May. The plan also included the seizure of Tulagi on 2–3 May, where the navy would establish a seaplane base for potential air operations against Allied territories and forces in the South Pacific and to provide a base for reconnaissance aircraft. Upon the completion of MO, the navy planned to initiate Operation RY, using ships released from MO, to seize Nauru and Ocean Island for their phosphate deposits on 15 May. Further operations against Fiji, Samoa and New Caledonia (Operation FS) were to be planned once MO and RY were completed. Because of a damaging air attack by Allied land- and carrier-based aircraft on Japanese naval forces invading the Lae-Salamaua area in New Guinea in March, Inoue requested Japan's Combined Fleet send carriers to provide air cover for MO. Inoue was especially worried about Allied bombers stationed at air bases in Townsville and Cooktown, Australia, beyond the range of his own bombers, based at Rabaul and Lae.[13]

Admiral Isoroku Yamamoto, commander of the Combined Fleet, was concurrently planning an operation for June that he hoped would lure the U.S. Navy's carriers, none of which had been damaged in the Pearl Harbor attack, into a decisive showdown in the central Pacific near Midway Atoll. In the meantime Yamamoto detached some of his large warships, including two fleet carriers, a light carrier, a cruiser division, and two destroyer divisions, to support MO, and placed Inoue in charge of the naval portion of the operation.[14]

### Allied response

[edit]

Frank Jack Fletcher, commander of U.S. Task Force 17

Unknown to the Japanese, the U.S. Navy, led by the Communication Security Section of the Office of Naval Communications, had for several years enjoyed increasing success with penetrating Japanese communication ciphers and codes. By March 1942, the U.S. was able to decipher up to 15% of the IJN's Ro or Naval Codebook D code (called "JN-25B" by the U.S.), which was used by the IJN for about half of its communications. By the end of April, the U.S. was reading up to 85% of the signals broadcast in the Ro code.[15]

In March 1942, the U.S. first noticed mention of the MO operation in intercepted messages. On 5 April, the U.S. intercepted an IJN message directing a carrier and other large warships to proceed to Inoue's area of operations. On 13 April, the British deciphered an IJN message informing Inoue that the Fifth Carrier Division, consisting of the fleet carriers Shōkaku and Zuikaku, was en route to his command from Formosa via the main IJN base at Truk. The British passed the message to the U.S., along with their conclusion that Port Moresby was the likely target of MO.[16]

Admiral Chester W. Nimitz, the new commander of U.S. forces in the Central Pacific, and his staff discussed the deciphered messages and agreed that the Japanese were likely initiating a major operation in the Southwest Pacific in early May with Port Moresby as the probable target. The Allies regarded Port Moresby as a key base for a planned counteroffensive, under General Douglas MacArthur, against Japanese forces in the South West Pacific area. Nimitz's staff also concluded that the Japanese operation might include carrier raids on Allied bases in Samoa and at Suva. Nimitz, after consultation with Admiral Ernest King, Commander in Chief of the United States Fleet, decided to contest the Japanese operation by sending all four of the Pacific Fleet's available aircraft carriers to the Coral Sea. By 27 April, further signals intelligence confirmed most of the details and targets of the MO and RY plans.[17]

On 29 April, Nimitz issued orders that sent his four carriers and their supporting warships towards the Coral Sea. Task Force 17 (TF 17), commanded by Rear Admiral Fletcher and consisting of the carrier Yorktown, escorted by three cruisers and four destroyers and supported by a replenishment group of two oilers and two destroyers, was already in the South Pacific, having departed Tongatabu on 27 April en route to the Coral Sea. TF 11, commanded by Rear Admiral Aubrey Fitch and consisting of the carrier Lexington with two cruisers and five destroyers, was between Fiji and New Caledonia. TF 16, commanded by Vice Admiral William F. Halsey and including the carriers Enterprise and Hornet, had just returned to Pearl Harbor from the Doolittle Raid in the central Pacific. TF 16 immediately departed but would not reach the South Pacific in time to participate in the battle. Nimitz placed Fletcher in command of Allied naval forces in the South Pacific area until Halsey arrived with TF 16.[18] Although the Coral Sea area was under MacArthur's command, Fletcher and Halsey were directed to continue to report to Nimitz while in the Coral Sea area, not to MacArthur.[19]

Based on un-encrypted intercepted radio traffic from TF 16 as it returned to Pearl Harbor, the Japanese assumed that all but one of the U.S. Navy's carriers were in the central Pacific. The Japanese did not know the location of the remaining carrier, but did not expect a U.S. carrier response to MO until the operation was well under way.[20]

## Battle

[edit]

### Prelude

[edit]

Further information: Battle of the Coral Sea order of battle

During late April, the Japanese submarines Ro-33 and Ro-34 reconnoitered the area where landings were planned. The submarines investigated Rossel Island and the Deboyne Group anchorage in the Louisiade Archipelago, Jomard Channel, and the route to Port Moresby from the east. They did not sight any Allied ships in the area and returned to Rabaul on 23 and 24 April respectively.[21]

The Japanese Port Moresby Invasion Force, commanded by Rear Admiral Kōsō Abe, included 11 transport ships carrying about 5,000 soldiers from the IJA's South Seas Detachment plus about 500 troops from the 3rd Kure Special Naval Landing Force (SNLF). Escorting the transports was the Port Moresby Attack Force with one light cruiser and six relatively old Kamikaze and Mutsuki-class destroyers under the command of Rear Admiral Sadamichi Kajioka. Abe's ships departed Rabaul for the 840 nmi (970 mi; 1,560 km) trip to Port Moresby on 4 May and were joined by Kajioka's force the next day. The ships, proceeding at 8 kn (9.2 mph; 15 km/h), planned to transit the Jomard Channel in the Louisiades to pass around the southern tip of New Guinea to arrive at Port Moresby by 10 May.[22] The Allied garrison at Port Moresby numbered around 5,333 men, but only half of these were infantry and all were badly equipped and undertrained.[23]

The Tulagi invasion force, commanded by Rear Admiral Kiyohide Shima, consisted of two minelayers, two older Mutsuki-class destroyers, five minesweepers, two subchasers and a transport ship carrying about 400 troops from the 3rd Kure SNLF. Supporting the Tulagi force was the covering group with the light carrier Shōhō, the IJN's four Furutaka /Aoba-class heavy cruisers, and one destroyer, commanded by Rear Admiral Aritomo Gotō. A separate cover force (sometimes referred to as the support group), commanded by Rear Admiral Kuninori Marumo and consisting of two light cruisers, the seaplane tender Kamikawa Maru and three gunboats, joined the covering group in providing distant protection for the Tulagi invasion. Once Tulagi was secured on 3 or 4 May, the covering group and cover force were to reposition to help screen the Port Moresby invasion.[25] Inoue directed the MO operation from the cruiser Kashima, with which he arrived at Rabaul from Truk on 4 May.[26]

Gotō's force left Truk on 28 April, cut through the Solomons between Bougainville and Choiseul and took station near New Georgia Island. Marumo's support group sortied from New Ireland on 29 April headed for Thousand Ships Bay, Santa Isabel Island, to establish a seaplane base on 2 May to support the Tulagi assault. Shima's invasion force departed Rabaul on 30 April.[27]

Zuikaku anchored in Kobe in September of 1941 after her commissioning.

The Carrier Strike Force, with the carriers Zuikaku and Shōkaku, two heavy cruisers, and six destroyers, sortied from Truk on 1 May. The strike force was commanded by Vice Admiral Takeo Takagi (flag on cruiser Myōkō), with Rear Admiral Chūichi Hara, on Zuikaku, in tactical command of the carrier air forces. The Carrier Strike Force was to proceed down the eastern side of the Solomon Islands and enter the Coral Sea south of Guadalcanal. Once in the Coral Sea, the carriers were to provide air cover for the invasion forces, eliminate Allied air power at Port Moresby, and intercept and destroy any Allied naval forces which entered the Coral Sea in response.[28]

En route to the Coral Sea, Takagi's carriers were to deliver nine Zero fighter aircraft to Rabaul. Bad weather during two attempts to make the delivery on 2–3 May compelled the aircraft to return to the carriers, stationed 240 nmi (280 mi; 440 km) from Rabaul, and one of the Zeros was forced to ditch in the sea. In order to try to keep to the MO timetable, Takagi was forced to abandon the delivery mission after the second attempt and direct his force towards the Solomon Islands to refuel.[29]

To give advance warning of the approach of any Allied naval forces, the Japanese sent submarines I-22, I-24, I-28 and I-29 to form a scouting line in the ocean about 450 nmi (520 mi; 830 km) southwest of Guadalcanal. Fletcher's forces had entered the Coral Sea area before the submarines took station, and the Japanese were therefore unaware of their presence. Another submarine, I-21, which was sent to scout around Nouméa, was attacked by Yorktown aircraft on 2 May. The submarine took no damage and apparently did not realize that it had been attacked by carrier aircraft. Ro-33 and Ro-34 were also deployed in an attempt to blockade Port Moresby, arriving off the town on 5 May. Neither submarine engaged any ships during the battle.[30]

Yorktown conducts aircraft operations in the Pacific sometime before the battle. A fleet oiler is in the near background.

On the morning of 1 May, TF 17 and TF 11 united about 300 nmi (350 mi; 560 km) northwest of New Caledonia (16°16′S 162°20′E﻿ / ﻿16.267°S 162.333°E﻿ / -16.267; 162.333).[31] Fletcher immediately detached TF 11 to refuel from the oiler Tippecanoe, while TF 17 refueled from Neosho. TF 17 completed refueling the next day, but TF 11 reported that they would not be finished fueling until 4 May. Fletcher elected to take TF 17 northwest towards the Louisiades and ordered TF 11 to meet TF 44, which was en route from Sydney and Nouméa, on 4 May once refueling was complete. TF 44 was a joint Australia–U.S. warship force under MacArthur's command, led by Australian Rear Admiral John Crace and made up of the cruisers HMAS Australia, Hobart, and USS Chicago, along with three destroyers. Once it completed refueling TF 11, Tippecanoe departed the Coral Sea to deliver its remaining fuel to Allied ships at Efate.[32]

### Tulagi

[edit]

Further information: Invasion of Tulagi (May 1942)

Early on 3 May, Shima's force arrived off Tulagi and began disembarking the naval troops to occupy the island. Tulagi was undefended: the small garrison of Australian commandos and a Royal Australian Air Force reconnaissance unit evacuated just before Shima's arrival. The Japanese forces immediately began construction of a seaplane and communications base. Aircraft from Shōhō covered the landings until early afternoon, when Gotō's force turned towards Bougainville to refuel in preparation to support the landings at Port Moresby.[33]

At 17:00 on 3 May, Fletcher was notified that the Japanese Tulagi invasion force had been sighted the day before, approaching the southern Solomons. Unknown to Fletcher, TF 11 completed refueling that morning ahead of schedule and was only 60 nmi (69 mi; 110 km) east of TF 17, but was unable to communicate its status because of Fletcher's orders to maintain radio silence. TF 17 changed course and proceeded at 27 kn (31 mph; 50 km/h) towards Guadalcanal to launch airstrikes against the Japanese forces at Tulagi the next morning.[34]

On 4 May, from a position 100 nmi (120 mi; 190 km) south of Guadalcanal (11°10′S 158°49′E﻿ / ﻿11.167°S 158.817°E﻿ / -11.167; 158.817), a total of 60 aircraft from TF 17 launched three consecutive strikes against Shima's forces off Tulagi. Yorktown's aircraft surprised Shima's ships and sank the destroyer Kikuzuki (09°07′S 160°12′E﻿ / ﻿9.117°S 160.200°E﻿ / -9.117; 160.200) and three of the minesweepers, damaged four other ships, and destroyed four seaplanes which were supporting the landings. The U.S. lost one torpedo bomber and two fighters in the strikes, but all of the aircrew were eventually rescued. After recovering its aircraft late in the evening of 4 May, TF 17 retired towards the south. In spite of the damage suffered in the carrier strikes, the Japanese continued construction of the seaplane base and began flying reconnaissance missions from Tulagi by 6 May.[35]

Takagi's Carrier Striking Force was refueling 350 nmi (400 mi; 650 km) north of Tulagi when it received word of Fletcher's strike on 4 May. Takagi terminated refueling, headed southeast, and sent scout planes to search east of the Solomons, believing that the U.S. carriers were in that area. Since no Allied ships were in that area, the search planes found nothing.[36]

### Air searches and decisions

[edit]

At 08:16 on 5 May, TF 17 rendezvoused with TF 11 and TF 44 at a predetermined point 320 nmi (370 mi; 590 km) south of Guadalcanal (15°S 160°E﻿ / ﻿15°S 160°E﻿ / -15; 160). At about the same time, four Grumman F4F Wildcat fighters from Yorktown intercepted a Kawanishi H6K reconnaissance flying boat from the Yokohama Air Group of the 25th Air Flotilla based at the Shortland Islands and shot it down 11 nmi (13 mi; 20 km) from TF 11\. The aircraft failed to send a report before it crashed, but when it didn't return to base the Japanese correctly assumed that it had been shot down by carrier aircraft.[37]

A message from Pearl Harbor notified Fletcher that radio intelligence deduced the Japanese planned to land their troops at Port Moresby on 10 May and their fleet carriers would likely be operating close to the invasion convoy. Armed with this information, Fletcher directed TF 17 to refuel from Neosho. After the refueling was completed on 6 May, he planned to take his forces north towards the Louisiades and do battle on 7 May.[38]

In the meantime, Takagi's carrier force steamed down the east side of the Solomons throughout the day on 5 May, turned west to pass south of San Cristobal (Makira), and entered the Coral Sea after transiting between Guadalcanal and Rennell Island in the early morning hours of 6 May. Takagi commenced refueling his ships 180 nmi (210 mi; 330 km) west of Tulagi in preparation for the carrier battle he expected would take place the next day.[39]

On 6 May, Fletcher absorbed TF 11 and TF 44 into TF 17\. Believing the Japanese carriers were still well to the north near Bougainville, Fletcher continued to refuel. Reconnaissance patrols conducted from the U.S. carriers throughout the day failed to locate any of the Japanese naval forces, because they were located just beyond scouting range.[40]

At 10:00, a Kawanishi reconnaissance flying boat from Tulagi sighted TF 17 and notified its headquarters. Takagi received the report at 10:50. At that time, Takagi's force was about 300 nmi (350 mi; 560 km) north of Fletcher, near the maximum range for his carrier aircraft. Takagi, whose ships were still refueling, was not yet ready to engage in battle. He concluded, based on the sighting report, TF 17 was heading south and increasing the range. Furthermore, Fletcher's ships were under a large, low-hanging overcast which Takagi and Hara felt would make it difficult for their aircraft to find the U.S. carriers. Takagi detached his two carriers with two destroyers under Hara's command to head towards TF 17 at 20 kn (23 mph; 37 km/h) in order to be in position to attack at first light the next day while the rest of his ships completed refueling.[41]

Animated map of the battle, 6–8 May

U.S. B-17 bombers based in Australia[42] and staging through Port Moresby attacked the approaching Port Moresby invasion forces, including Gotō's warships, several times during the day on 6 May without success. MacArthur's headquarters radioed Fletcher with reports of the attacks and the locations of the Japanese invasion forces. MacArthur's fliers' reports of seeing a carrier (Shōhō) about 425 nmi (489 mi; 787 km) northwest of TF 17 further convinced Fletcher fleet carriers were accompanying the invasion force.[43]

At 18:00, TF 17 completed fueling and Fletcher detached Neosho with a destroyer, Sims, to take station further south at a prearranged rendezvous (16°S 158°E﻿ / ﻿16°S 158°E﻿ / -16; 158). TF 17 then turned to head northwest towards Rossel Island in the Louisiades. Unbeknownst to the two adversaries, their carriers were only 70 nmi (130 km) away from each other by 20:00 that night. At 20:00 (13°20′S 157°40′E﻿ / ﻿13.333°S 157.667°E﻿ / -13.333; 157.667), Hara reversed course to meet Takagi who completed refueling and was now heading in Hara's direction.[44]

Late on 6 May or early on 7 May, Kamikawa Maru set up a seaplane base in the Deboyne Islands in order to help provide air support for the invasion forces as they approached Port Moresby. The rest of Marumo's Cover Force then took station near the D'Entrecasteaux Islands to help screen Abe's oncoming convoy.[45]

### Carrier battle, first day

[edit]

#### Morning strikes

[edit]

At 06:25 on 7 May, TF 17 was 115 nmi (132 mi; 213 km) south of Rossel Island (13°20′S 154°21′E﻿ / ﻿13.333°S 154.350°E﻿ / -13.333; 154.350). At this time, Fletcher sent Crace's cruiser force, now designated Task Group 17.3 (TG 17.3), to block the Jomard Passage. Fletcher understood that Crace would be operating without air cover since TF 17's carriers would be busy trying to locate and attack the Japanese carriers. Detaching Crace reduced the anti-aircraft defenses for Fletcher's carriers. Nevertheless, Fletcher decided the risk was necessary to ensure the Japanese invasion forces could not slip through to Port Moresby while he engaged the carriers.[46]

Japanese carrier dive bombers head towards the reported position of U.S. carriers on 7 May.

Believing Takagi's carrier force was somewhere north of him, in the vicinity of the Louisiades, beginning at 06:19, Fletcher directed Yorktown to send 10 Douglas SBD Dauntless dive bombers as scouts to search that area. Hara in turn believed Fletcher was south of him and advised Takagi to send the aircraft to search that area. Takagi, about 300 nmi (350 mi; 560 km) east of Fletcher (13°12′S 158°05′E﻿ / ﻿13.200°S 158.083°E﻿ / -13.200; 158.083), launched 12 Nakajima B5Ns at 06:00 to scout for TF 17\. Around the same time, Gotō's cruisers Kinugasa and Furutaka launched four Kawanishi E7K2 Type 94 floatplanes to search southeast of the Louisiades. Augmenting their search were several floatplanes from Deboyne, four Kawanishi H6Ks from Tulagi, and three Mitsubishi G4M bombers from Rabaul. Each side readied the rest of its carrier attack aircraft to launch immediately once the enemy was located.[47]

At 07:22 one of Takagi's carrier scouts, from Shōkaku, reported U.S. ships bearing 182° (just west of due south), 163 nmi (188 mi; 302 km) from Takagi. At 07:45, the scout confirmed that it had located "one carrier, one cruiser, and three destroyers". Another Shōkaku scout aircraft quickly confirmed the sighting.[48] The Shōkaku aircraft actually sighted and misidentified the oiler Neosho and destroyer Sims, which had earlier been detailed away from the fleet to a southern rendezvous point. Believing that he had located the U.S. carriers, Hara, with Takagi's concurrence, immediately launched all of his available aircraft. A total of 78 aircraft—18 Zero fighters, 36 Aichi D3A dive bombers, and 24 torpedo aircraft—began launching from Shōkaku and Zuikaku at 08:00 and were on their way by 08:15 towards the reported sighting. The strike force was under overall command of Lieutenant Commander Kakuichi Takahashi, while Lieutenant Commander Shigekazu Shimazaki led its torpedo bombers.[49]

At 08:20, one of the Furutaka aircraft found Fletcher's carriers and immediately reported it to Inoue's headquarters at Rabaul, which passed the report on to Takagi. The sighting was confirmed by a Kinugasa floatplane at 08:30. Takagi and Hara, confused by the conflicting sighting reports they were receiving, decided to continue with the strike on the ships to their south, but turned their carriers towards the northwest to close the distance with Furutaka's reported contact.[50] Takagi and Hara considered that the conflicting reports might mean that the U.S. carrier forces were operating in two separate groups.[51]

At 08:15, a Yorktown SBD piloted by John L. Nielsen sighted Gotō's force screening the invasion convoy. Nielsen, making an error in his coded message, reported the sighting as "two carriers and four heavy cruisers" at 10°3′S 152°27′E﻿ / ﻿10.050°S 152.450°E﻿ / -10.050; 152.450, 225 nmi (259 mi; 417 km) northwest of TF17.[52] Fletcher concluded that the Japanese main carrier force was located and ordered the launch of all available carrier aircraft to attack. By 10:13, the U.S. strike of 93 aircraft—18 Grumman F4F Wildcats, 53 Douglas SBD Dauntless dive bombers, and 22 Douglas TBD Devastator torpedo bombers—was on its way. At 10:19, Nielsen landed and discovered his coding error. Although Gotō's force included the light carrier Shōhō, Nielsen thought that he saw two cruisers and four destroyers and thus the main fleet. At 10:12, Fletcher received a report of an aircraft carrier, ten transports, and 16 warships 30 nmi (35 mi; 56 km) south of Nielsen's sighting at 10°35′S 152°36′E﻿ / ﻿10.583°S 152.600°E﻿ / -10.583; 152.600. The B-17s actually saw the same thing as Nielsen: Shōhō, Gotō's cruisers, plus the Port Moresby Invasion Force. Believing that the B-17's sighting was the main Japanese carrier force (which was in fact well to the east), Fletcher directed the airborne strike force towards this target.[53]

USS Neosho is left burning and slowly sinking at the completion of the Japanese dive bombing attack.

At 09:15, Takahashi's strike force reached its target area, sighted Neosho and Sims, and searched in vain for the U.S. carriers for a couple of hours. Finally, at 10:51 Shōkaku scout aircrews realized they were mistaken in their identification of the oiler and destroyer as aircraft carriers. Takagi now realized the U.S. carriers were between him and the invasion convoy, placing the invasion forces in extreme danger. At 11:15, the torpedo bombers and fighters abandoned the mission and headed back towards the carriers with their ordnance, while the 36 dive bombers attacked the two U.S. ships.[54]

Four dive bombers attacked Sims and the rest dived on Neosho. The destroyer was hit by three bombs, broke in half, and sank immediately, killing all but 14 of her 192-man crew. Neosho was hit by seven bombs. One of the dive bombers, hit by anti-aircraft fire, crashed into the oiler. Heavily damaged and without power, Neosho was left drifting and slowly sinking (16°09′S 158°03′E﻿ / ﻿16.150°S 158.050°E﻿ / -16.150; 158.050). Before losing power, Neosho was able to notify Fletcher by radio that she was under attack and in trouble, but garbled any further details as to just who or what was attacking her and gave wrong coordinates (16°25′S 157°31′E﻿ / ﻿16.417°S 157.517°E﻿ / -16.417; 157.517) for her position.[55]

The U.S. strike aircraft sighted Shōhō a short distance northeast of Misima Island at 10:40 and deployed to attack. The Japanese carrier was protected by four Zeros and two Mitsubishi A5M fighters flying combat air patrol (CAP), as the rest of the carrier's aircraft were being prepared below decks for a strike against the U.S. carriers. Gotō's cruisers surrounded the carrier in a diamond formation, 3,000–5,000 yd (2,700–4,600 m) off each of Shōhō's corners.[56]

Shōhō is bombed and torpedoed by U.S. carrier aircraft.

Attacking first, Lexington's air group, led by Commander William B. Ault, hit Shōhō with two 1,000 lb (450 kg) bombs and five torpedoes, causing severe damage. At 11:00, Yorktown's air group attacked the burning and now almost stationary carrier, scoring with up to 11 more 1,000 lb (450 kg) bombs and at least two torpedoes. Torn apart, Shōhō sank at 11:35 (10°29′S 152°55′E﻿ / ﻿10.483°S 152.917°E﻿ / -10.483; 152.917). Fearing more air attacks, Gotō withdrew his warships to the north, but sent the destroyer Sazanami back at 14:00 to rescue survivors. Only 203 of the carrier's 834-man crew were recovered. Three U.S. aircraft were lost in the attack: two SBDs from Lexington and one from Yorktown. All of Shōhō's aircraft complement of 18 was lost, but three of the CAP fighter pilots were able to ditch at Deboyne and survived. At 12:10, using a prearranged message to signal TF 17 on the success of the mission, Lexington SBD pilot and squadron commander Robert E. Dixon radioed "Scratch one flat top! Signed Bob."[57]

#### Afternoon operations

[edit]

The U.S. aircraft returned and landed on their carriers by 13:38. By 14:20, the aircraft were rearmed and ready to launch against the Port Moresby Invasion Force or Gotō's cruisers. Fletcher was concerned that the locations of the rest of the Japanese fleet carriers were still unknown. He was informed that Allied intelligence sources believed that up to four Japanese carriers might be supporting the MO operation. Fletcher concluded that by the time his scout aircraft found the remaining carriers it would be too late in the day to mount a strike. Thus, Fletcher decided to hold off on another strike this day and remain concealed under the thick overcast with fighters ready in defense. Fletcher turned TF 17 southwest.[58]

Apprised of the loss of Shōhō, Inoue ordered the invasion convoy to temporarily withdraw to the north and ordered Takagi, at this time located 225 nmi (259 mi; 417 km) east of TF 17, to destroy the U.S. carrier forces. As the invasion convoy reversed course, it was bombed by eight U.S. Army B-17s, but was not damaged. Gotō and Kajioka were told to assemble their ships south of Rossel Island for a night surface battle if the U.S. ships came within range.[59]

At 12:40, a Deboyne-based seaplane sighted and reported Crace's detached cruiser and destroyer force on a bearing of 175°, 78 nmi (90 mi; 144 km) from Deboyne. At 13:15, an aircraft from Rabaul sighted Crace's force but submitted an erroneous report, stating the force contained two carriers and was located, bearing 205°, 115 nmi (213 km) from Deboyne. Based on these reports, Takagi, who was still awaiting the return of all of his aircraft from attacking Neosho, turned his carriers due west at 13:30 and advised Inoue at 15:00 that the U.S. carriers were at least 430 nmi (490 mi; 800 km) west of his location and that he would therefore be unable to attack them that day.[60]

HMAS Australia (center) and TG17.3 under air attack on 7 May

Inoue's staff directed two groups of attack aircraft from Rabaul, already airborne since that morning, towards Crace's reported position. The first group included 12 torpedo-armed G4M bombers and the second group comprised 19 Mitsubishi G3M land attack aircraft armed with bombs. Both groups found and attacked Crace's ships at 14:30 and claimed to have sunk a "California-type" battleship and damaged another battleship and cruiser. In reality, Crace's ships were lightly damaged and shot down four G4Ms. A short time later, three U.S. Army B-17s mistakenly bombed Crace, but caused no damage.[61] At the conclusion of the attack, the detachment of cruisers suffered several wounded and a few men killed aboard the Chicago.

Crace at 15:26 radioed Fletcher he could not complete his mission without air support. Crace retired southward to a position about 220 nmi (250 mi; 410 km) southeast of Port Moresby to increase the range from Japanese carrier- or land-based aircraft while remaining close enough to intercept any Japanese naval forces advancing beyond the Louisiades through either the Jomard Passage or the China Strait. Crace's ships were low on fuel, and as Fletcher was maintaining radio silence (and had not informed him in advance), Crace had no idea of Fletcher's location, status, or intentions.[62]

Shortly after 15:00, Zuikaku monitored a message from a Deboyne-based reconnaissance aircraft reporting (incorrectly) that Crace's force had altered course to 120° true (southeast). Takagi's staff assumed the aircraft was shadowing Fletcher's carriers and determined if the Allied ships held that course, they would be within striking range shortly before nightfall. Takagi and Hara were determined to attack immediately with a select group of aircraft, minus fighter escort, even though it meant the strike would return after dark.[63]

To try to confirm the location of the U.S. carriers, at 15:15 Hara sent a flight of eight torpedo bombers as scouts to sweep 200 nmi (230 mi; 370 km) westward. About that same time, the dive bombers that had attacked Neosho returned and landed. Six of the weary dive bomber pilots were told they would be immediately departing on another mission. Choosing his most experienced crews, including Takahashi, Shimazaki and Lieutenant Tamotsu Ema, at 16:15 Hara launched 12 dive bombers and 15 torpedo planes with orders to fly on a heading of 277° to 280 nmi (320 mi; 520 km). The eight scout aircraft reached the end of their 200 nmi (230 mi; 370 km) search leg and turned back without seeing Fletcher's ships.[64]

At 17:47, TF 17 – operating under thick overcast 200 nmi (230 mi; 370 km) west of Takagi – detected the Japanese strike on radar heading in their direction, turned southeast into the wind, and vectored 11 CAP Wildcats, led by Lieutenant Commanders Paul H. Ramsey and James H. Flatley, to intercept. Taking the Japanese formation by surprise, the Wildcats shot down seven torpedo bombers and one dive bomber, and heavily damaged another torpedo bomber (which later crashed), at a cost of three Wildcats lost.[65]

Having taken heavy losses in the attack, which also scattered their formations, the Japanese strike leaders canceled the mission after conferring by radio. The Japanese aircraft all jettisoned their ordnance and reversed course to return to their carriers. The sun set at 18:30. Several of the Japanese dive bombers encountered the U.S. carriers in the darkness, around 19:00, and briefly confused as to their identity, circled in preparation for landing before anti-aircraft fire from TF 17's destroyers drove them away. By 20:00, TF 17 and Takagi were about 100 nmi (120 mi; 190 km) apart. Takagi turned on his warships' searchlights to help guide the 18 surviving aircraft back and all were recovered by 22:00.[66]

In the meantime, at 15:18 and 17:18 Neosho was able to radio TF 17 she was drifting northwest in dire straits. Neosho's 17:18 report gave wrong coordinates, which hampered subsequent U.S. rescue efforts to locate the oiler. More significantly, the news informed Fletcher his only nearby available fuel supply was gone.[67]

As nightfall ended aircraft operations for the day, Fletcher ordered TF 17 to head west and prepared to launch a 360° search at first light. Crace also turned west to stay within striking range of the Louisiades. Inoue directed Takagi to make sure he destroyed the U.S. carriers the next day, and postponed the Port Moresby landings to 12 May. Takagi elected to take his carriers 120 nmi (140 mi; 220 km) north during the night so he could concentrate his morning search to the west and south and ensure that his carriers could provide better protection for the invasion convoy. Gotō and Kajioka were unable to position and coordinate their ships in time to attempt a night attack on the Allied warships.[68]

Both sides expected to find each other early the next day, and spent the night preparing their strike aircraft for the anticipated battle as their exhausted aircrews attempted to get a few hours' sleep. In 1972, U.S. Vice Admiral H. S. Duckworth, after reading Japanese records of the battle, commented, "Without a doubt, May 7, 1942, vicinity of Coral Sea, was the most confused battle area in world history."[69] Hara later told Yamamoto's chief of staff, Admiral Matome Ugaki, he was so frustrated with the "poor luck" the Japanese experienced on 7 May that he felt like quitting the navy.[70]

### Carrier battle, second day

[edit]

#### Attack on the Japanese carriers

[edit]

Yorktown (foreground) and Lexington turn to launch aircraft under clear skies on 8 May.

At 06:15 on 8 May, from a position 100 nmi (120 mi; 190 km) east of Rossel Island (10°25′S 154°5′E﻿ / ﻿10.417°S 154.083°E﻿ / -10.417; 154.083), Hara launched seven torpedo bombers to search the area bearing 140–230°, out to 250 nmi (290 mi; 460 km) from the Japanese carriers. Assisting in the search were three Kawanishi H6Ks from Tulagi and four G4M bombers from Rabaul. At 07:00, the carrier striking force turned to the southwest and was joined by two of Gotō's cruisers, Kinugasa and Furutaka, for additional screening support. The invasion convoy, Gotō, and Kajioka steered towards a rendezvous point 40 nmi (46 mi; 74 km) east of Woodlark Island to await the outcome of the carrier battle. During the night, the warm frontal zone with low clouds which had helped hide the U.S. carriers on 7 May moved north and east and now covered the Japanese carriers, limiting visibility to between 2 and 15 nmi (2.3 and 17.3 mi; 3.7 and 27.8 km).[71]

At 06:35, TF 17 – operating under Fitch's tactical control and positioned 180 nmi (210 mi; 330 km) southeast of the Louisiades, launched 18 SBDs to conduct a 360° search out to 200 nmi (230 mi; 370 km). The skies over the U.S. carriers were mostly clear, with 17 nmi (20 mi; 31 km) visibility.[72]

At 08:20, a Lexington SBD piloted by Joseph G. Smith spotted the Japanese carriers through a hole in the clouds and notified TF 17\. Two minutes later, a Shōkaku search plane commanded by Kenzō Kanno sighted TF 17 and notified Hara. The two forces were about 210 nmi (240 mi; 390 km) apart. Both sides raced to launch their strike aircraft.[73]

At 09:15, the Japanese carriers launched a combined strike of 18 fighters, 33 dive bombers, and 18 torpedo planes, commanded by Takahashi, with Shimazaki again leading the torpedo bombers. The U.S. carriers each launched a separate strike. Yorktown's group consisted of 6 fighters, 24 dive bombers, and 9 torpedo planes and was on its way by 09:15. Lexington's group of 9 fighters, 15 dive bombers, and 12 torpedo planes was off at 09:25. Both the U.S. and Japanese carrier warship forces turned to head directly for each other's location at high speed in order to shorten the distance their aircraft would have to fly on their return legs.[74]

Shōkaku, at high speed and turning hard, has suffered bomb strikes and is afire.

Yorktown's dive bombers, led by William O. Burch, reached the Japanese carriers at 10:32, and paused to allow the slower torpedo squadron to arrive so that they could conduct a simultaneous attack. At this time, Shōkaku and Zuikaku were about 10,000 yd (9,100 m) apart, with Zuikaku hidden under a rain squall of low-hanging clouds. The two carriers were protected by 16 CAP Zero fighters. The Yorktown dive bombers commenced their attacks at 10:57 on Shōkaku and hit the radically maneuvering carrier with two 1,000 lb (450 kg) bombs, tearing open the forecastle and causing heavy damage to the carrier's flight and hangar decks. The Yorktown torpedo planes missed with all of their ordnance. Two U.S. dive bombers and two CAP Zeros were shot down during the attack.[75]

Lexington's aircraft arrived and attacked at 11:30. Two dive bombers attacked Shōkaku, hitting the carrier with one 1,000 lb (450 kg) bomb, causing further damage. Two other dive bombers dove on Zuikaku, missing with their bombs. The rest of Lexington's dive bombers were unable to find the Japanese carriers in the heavy clouds. Lexington's TBDs missed Shōkaku with all 11 of their torpedoes. The 13 CAP Zeros on patrol at this time shot down 3 Wildcats.[76]

With her flight deck heavily damaged and 223 of her crew killed or wounded, having also suffered explosions in her gasoline storage tanks and an engine repair workshop destroyed, Shōkaku was unable to conduct further aircraft operations. Her captain, Takatsugu Jōjima, requested permission from Takagi and Hara to withdraw from the battle, to which Takagi agreed. At 12:10, Shōkaku, accompanied by two destroyers, retired to the northeast.[77]

#### Attack on the U.S. carriers

[edit]

At 10:55, Lexington's CXAM-1 radar detected the inbound Japanese aircraft at a range of 68 nmi (78 mi; 126 km) and vectored nine Wildcats to intercept. Expecting the Japanese torpedo bombers to be at a much lower altitude than they actually were, six of the Wildcats were stationed too low, and thus missed the Japanese aircraft as they passed by overhead.[78] Because of the heavy losses in aircraft suffered the night before, the Japanese could not execute a full torpedo attack on both carriers. Lieutenant Commander Shigekazu Shimazaki, commanding the Japanese torpedo planes, sent 14 to attack Lexington and 4 to attack Yorktown. A Wildcat shot down one and patrolling SBDs (8 from Yorktown, 15 from Lexington) destroyed 3 more as the Japanese torpedo planes descended to take attack position. In return, escorting Zeros shot down 4 Yorktown SBDs.[79] One of the survivors, Swede Vejtasa, claimed 3 Zeros during the onslaught (though none were lost).[80][81]

The Japanese attack began at 11:13 as the carriers, stationed 3,000 yd (2,700 m) apart, and their escorts opened fire with anti-aircraft guns. The four torpedo planes which attacked Yorktown all missed. The remaining torpedo planes successfully employed a pincer attack on Lexington, which had a much larger turning radius than Yorktown, and, at 11:20, hit her with two Type 91 torpedoes. The first torpedo buckled the port aviation gasoline stowage tanks. Undetected, gasoline vapors spread into surrounding compartments. The second torpedo ruptured the port water main, reducing water pressure to the three forward firerooms and forcing the associated boilers to be shut down. The ship could still make 24 kn (28 mph; 44 km/h) with her remaining boilers. Four of the Japanese torpedo planes were shot down by anti-aircraft fire.[82]

The 33 Japanese dive bombers circled to attack from upwind, and thus did not begin their dives from 14,000 ft (4,300 m) until three to four minutes after the torpedo planes began their attacks. The 19 Shōkaku dive bombers, under Takahashi, lined up on Lexington while the remaining 14, directed by Tamotsu Ema, targeted Yorktown. Escorting Zeros shielded Takahashi's aircraft from four Lexington CAP Wildcats which attempted to intervene, but two Wildcats circling above Yorktown were able to disrupt Ema's formation. Takahashi's bombers damaged Lexington with two bomb hits and several near misses, causing fires which were contained by 12:33. At 11:27, Yorktown was hit in the centre of her flight deck by a single 250 kg (550 lb), semi-armour-piercing bomb which penetrated four decks before exploding, causing severe structural damage to an aviation storage room and killing or seriously wounding 66 men, as well as damaging the superheater boilers which rendered them inoperable. Up to 12 near misses damaged Yorktown's hull below the waterline. Two of the dive bombers were shot down by a CAP Wildcat during the attack.[83]

As the Japanese aircraft completed their attacks and began to withdraw, believing that they inflicted fatal damage to both carriers, they ran a gauntlet of CAP Wildcats and SBDs. In the ensuing aerial duels, three SBDs and three Wildcats for the U.S., and three torpedo bombers, one dive bomber, and one Zero for the Japanese were downed. By 12:00, the U.S. and Japanese strike groups were on their way back to their respective carriers. During their return, aircraft from the two adversaries passed each other in the air, resulting in more air-to-air altercations. Kanno's and Takahashi's aircraft were shot down, killing both of them.[84] Two future U.S. destroyers were named after naval pilots lost in this confrontation: the USS Rinehart and USS Mason.

#### Recovery, reassessment and retreat

[edit]

The strike forces, with many damaged aircraft, reached and landed on their respective carriers between 12:50 and 14:30. In spite of damage, Yorktown and Lexington were able to recover aircraft from their returning air groups. During recovery operations, for various reasons the U.S. lost an additional five SBDs, two TBDs, and a Wildcat, and the Japanese lost two Zeros, five dive bombers, and one torpedo plane. Forty-six of the original sixty-nine aircraft from the Japanese strike force returned from the mission and landed on Zuikaku. Of these, three more Zeros, four dive bombers and five torpedo planes were judged damaged beyond repair and were immediately jettisoned into the sea.[85]

As TF 17 recovered its aircraft, Fletcher assessed the situation. The returning aviators reported they heavily damaged one carrier, but that another had escaped damage. Fletcher noted that both his carriers were hurt and that his air groups had suffered high fighter losses. Fuel was also a concern due to the loss of Neosho. At 14:22, Fitch notified Fletcher that he had reports of two undamaged Japanese carriers and that this was supported by radio intercepts. Believing that he faced overwhelming Japanese carrier superiority, Fletcher elected to withdraw TF 17 from the battle. Fletcher radioed MacArthur the approximate position of the Japanese carriers and suggested that he attack with his land-based bombers.[86]

Around 14:30, Hara informed Takagi that only 24 Zeros, 8 dive bombers, and 4 torpedo planes from the carriers were currently operational. Takagi was worried about his ships' fuel levels; his cruisers were at 50% and some of his destroyers were as low as 20%. At 15:00, Takagi notified Inoue his fliers had sunk two U.S. carriers – Yorktown and a "Saratoga-class" – but heavy losses in aircraft meant he could not continue to provide air cover for the invasion. Inoue, whose reconnaissance aircraft sighted Crace's ships earlier that day, recalled the invasion convoy to Rabaul, postponed MO to 3 July, and ordered his forces to assemble northeast of the Solomons to begin the RY operation. Zuikaku and her escorts turned towards Rabaul while Shōkaku headed for Japan.[87]

Lexington, burning and abandoned

Aboard Lexington, damage control parties put out the fires and restored her to operational condition, but at 12:47, sparks from unattended electric motors ignited gasoline fumes near the ship's central control station. The resulting explosion killed 25 men and started a large fire. Around 14:42, another large explosion occurred, starting a second severe fire. A third explosion occurred at 15:25 and at 15:38 the ship's crew reported the fires as uncontrollable. Lexington's crew began abandoning ship at 17:07. After the carrier's survivors were rescued, including Admiral Fitch and the ship's captain, Frederick C. Sherman, at 19:15 the destroyer Phelps fired five torpedoes into the burning ship, which sank in 2,400 fathoms at 19:52 (15°15′S 155°35′E﻿ / ﻿15.250°S 155.583°E﻿ / -15.250; 155.583). Two hundred and sixteen of the carrier's 2,951-man crew went down with the ship, along with 36 aircraft. Phelps and the other assisting warships left immediately to rejoin Yorktown and her escorts, which departed at 16:01, and TF 17 retired to the southwest. Later that evening, MacArthur informed Fletcher that eight of his B-17s had attacked the invasion convoy and that it was retiring to the northwest.[88]

That evening, Crace detached Hobart, which was critically low on fuel, and the destroyer Walke, which was having engine trouble, to proceed to Townsville. Crace overheard radio reports saying the enemy invasion convoy had turned back, but, unaware Fletcher had withdrawn, he remained on patrol with the rest of TG 17.3 in the Coral Sea in case the Japanese invasion force resumed its advance towards Port Moresby.[89]

## Aftermath

[edit]

On 9 May, TF 17 altered course to the east and proceeded out of the Coral Sea via a route south of New Caledonia. Nimitz ordered Fletcher to return Yorktown to Pearl Harbor as soon as possible after refueling at Tongatabu. During the day, U.S. Army bombers attacked Deboyne and Kamikawa Maru, inflicting unknown damage. In the meantime, having heard nothing from Fletcher, Crace deduced that TF17 had departed the area. At 01:00 on 10 May, hearing no further reports of Japanese ships advancing towards Port Moresby, Crace turned towards Australia and arrived at Cid Harbor, 130 nmi (150 mi; 240 km) south of Townsville, on 11 May.[90]

At 22:00 on 8 May, Yamamoto ordered Inoue to turn his forces around, destroy the remaining Allied warships, and complete the invasion of Port Moresby. Inoue did not cancel the recall of the invasion convoy, but ordered Takagi and Gotō to pursue the remaining Allied warship forces in the Coral Sea. Critically low on fuel, Takagi's warships spent most of 9 May refueling from the fleet oiler Tōhō Maru. Late in the evening of 9 May, Takagi and Gotō headed southeast, then southwest into the Coral Sea. Seaplanes from Deboyne assisted Takagi in searching for TF 17 on the morning of 10 May. Fletcher and Crace were already well on their way out of the area. At 13:00 on 10 May, Takagi concluded that the enemy was gone and decided to turn back towards Rabaul. Yamamoto concurred with Takagi's decision and ordered Zuikaku to return to Japan to replenish her air groups. At the same time, Kamikawa Maru packed up and departed Deboyne.[91] At noon on 11 May, a U.S. Navy PBY on patrol from Nouméa sighted the drifting Neosho (15°35′S 155°36′E﻿ / ﻿15.583°S 155.600°E﻿ / -15.583; 155.600). The U.S. destroyer Henley responded and rescued 109 Neosho and 14 Sims survivors later that day, then scuttled the tanker with gunfire.[92][93]

Bomb damage to Shōkaku's bow and forward flight deck

On 10 May, Operation RY commenced. After the operation's flagship, minelayer Okinoshima, was sunk by the U.S. submarine S-42 on 12 May (05°06′S 153°48′E﻿ / ﻿5.100°S 153.800°E﻿ / -5.100; 153.800), the landings were postponed until 17 May. In the meantime, Halsey's TF 16 reached the South Pacific near Efate and, on 13 May, headed north to contest the Japanese approach to Nauru and Ocean Island. On 14 May, Nimitz, having obtained intelligence concerning the Combined Fleet's upcoming operation against Midway, ordered Halsey to make sure that Japanese scout aircraft sighted his ships the next day, after which he was to return to Pearl Harbor immediately. At 10:15 on 15 May, a Kawanishi reconnaissance aircraft from Tulagi sighted TF 16 445 nmi (512 mi; 824 km) east of the Solomons. Halsey's feint worked. Fearing a carrier air attack on his exposed invasion forces, Inoue immediately canceled RY and ordered his ships back to Rabaul and Truk. On 19 May, TF 16 – which returned to the Efate area to refuel – turned towards Pearl Harbor and arrived there on 26 May. Yorktown reached Pearl the following day.[94]

Shōkaku reached Kure, Japan, on 17 May, almost capsizing en route during a storm due to her battle damage. Zuikaku arrived at Kure on 21 May, having made a brief stop at Truk on 15 May. Acting on signals intelligence, the U.S. placed eight submarines along the projected route of the carriers' return paths to Japan, but the submarines were not able to make any attacks. Japan's Naval General Staff estimated that it would take two to three months to repair Shōkaku and replenish the carriers' air groups. Thus, both carriers would be unable to participate in Yamamoto's upcoming Midway operation. The two carriers rejoined the Combined Fleet on 14 July and were key participants in subsequent carrier battles against U.S. forces. The five I-class submarines supporting the MO operation were retasked to support an attack on Sydney Harbour three weeks later as part of a campaign to disrupt Allied supply lines. En route to Truk the submarine I-28 was torpedoed on 17 May by the U.S. submarine Tautog and sank with all hands.[95]

## Significance

[edit]

The public on both sides were informed of victory with overstatement of enemy losses and understatement of their own—the Americans claimed to have sunk between 18 and 37 ships.[96] In terms of actual ships lost, the Japanese won a tactical victory by sinking the U.S. fleet carrier Lexington, an oiler, and a destroyer—41,826 long tons (42,497 t)—versus a light carrier, a destroyer, and several smaller warships—19,000 long tons (19,000 t)—sunk by the U.S. side. Lexington represented, at that time, 25% of U.S. carrier strength in the Pacific.[97]

From a strategic perspective, however, the battle was an Allied victory as it averted the seaborne invasion of Port Moresby, lessening the threat to the supply lines between the U.S. and Australia. Although the withdrawal of Yorktown from the Coral Sea conceded the field, the Japanese were forced to abandon the operation that had initiated the Battle of the Coral Sea in the first place.[98]

The battle marked the first time that a Japanese invasion force was turned back without achieving its objective, which greatly lifted the morale of the Allies after a series of defeats by the Japanese during the initial six months of the Pacific Theatre. Port Moresby was vital to Allied strategy and its garrison could well have been overwhelmed by the experienced Japanese invasion troops. The U.S. Navy also exaggerated the damage it inflicted, which later caused the press to treat its reports of Midway with more caution.[99]

The results of the battle had a substantial effect on the strategic planning of both sides. Without a hold in New Guinea, the subsequent Allied advance, arduous as it was, would have been even more difficult.[100] For the Japanese, who focused on the tactical results, the battle was seen as merely a temporary setback. The results of the battle confirmed the low opinion held by the Japanese of U.S. fighting capability and supported their overconfident belief that future carrier operations against the U.S. were assured of success.[101]

### Forces available for Midway

[edit]

One of the most significant effects of the Coral Sea battle was the temporary loss of Shōkaku and Zuikaku to Yamamoto's planned battle against the U.S. carriers at Midway. (Shōhō was to have been employed at Midway in a tactical role supporting the Japanese invasion ground forces.) Although Zuikaku was undamaged, she had lost a large number of aircraft in the battle, and the Japanese apparently did not even consider trying to include Zuikaku in the forthcoming operation. No effort appears to have been made to combine the surviving Shōkaku aircrews with Zuikaku's air groups or to quickly provide Zuikaku with replacement aircraft. Shōkaku herself was unable to conduct further aircraft operations, with her flight deck heavily damaged, and she required almost three months of repair in Japan.[102]

The Japanese believed that they sank two carriers in the Coral Sea, but this still left at least two more U.S. Navy carriers, Enterprise and Hornet, to help defend Midway. In fact, Yorktown had only been damaged, but she had also lost a large number of planes in the battle. Unlike the Japanese, the U.S. Navy put forth a maximum effort to make Yorktown available for the coming battle. Although the damage was estimated to take 90 days to repair, Nimitz gave the shipyard only three days, and only the most critical repairs were made to make the ship seaworthy. Yorktown left Pearl Harbor with three of her boilers inoperative and a maximum speed of 27 knots.[103] Unlike the Japanese, the U.S. Navy was willing to put one aircraft carrier's air group on another ship. To make up aircraft losses from the Coral Sea, three of the four Yorktown squadrons were sent ashore and replaced by squadrons from Saratoga, which had been sent to the West Coast for repairs after being torpedoed by a Japanese submarine. Yorktown would go into battle with her own scouting squadron, but Saratoga's torpedo bomber, dive bomber, and fighter squadrons.

The U.S. aircraft carriers had slightly larger aircraft complements than the Japanese carriers, which, when combined with the land-based aircraft at Midway, the availability of Yorktown, and the loss of two Japanese carriers, meant that the Japanese Navy and the U.S. Navy would have near parity in aircraft for the impending battle. At Midway, aircraft flying from Yorktown played crucial roles in the American victory. Yorktown's planes sank the Sōryū, located Hiryū, and helped Enterprise planes sink Hiryū. Yorktown also absorbed both Japanese aerial counterattacks at Midway which otherwise would have been directed at Enterprise and Hornet.[104]

Historians H. P. Willmott, Jonathan Parshall, and Anthony Tully believe Yamamoto made a significant strategic error in his decision to support Operation MO with strategic assets. Since Yamamoto had decided the decisive battle with the U.S. was to take place at Midway, he should not have diverted any of his important assets, especially fleet carriers, to a secondary operation like MO. Yamamoto's decision meant Japanese naval forces were weakened just enough at both the Coral Sea and Midway battles to allow the Allies to defeat them in detail. Willmott adds, if either operation was important enough to commit fleet carriers, then all of the Japanese carriers should have been committed to each in order to ensure success. By committing crucial assets to MO, Yamamoto made the more important Midway operation dependent on the secondary operation's success.[105]

Moreover, Yamamoto apparently missed the other implications of the Coral Sea battle: the unexpected appearance of U.S. carriers in exactly the right place and time (due to cryptanalysis) to effectively contest the Japanese, and U.S. Navy carrier aircrews demonstrating sufficient skill and determination to do significant damage to the Japanese carrier forces. These would be repeated at Midway, for the same reason, and as a result, Japan lost four fleet carriers, the core of her naval offensive forces, and thereby lost the strategic initiative in the Pacific War. Parshall and Tully point out that, due to U.S. industrial strength, once Japan lost its numerical superiority in carrier forces as a result of Midway, Japan could never regain it. Parshall and Tully add, "The Battle of the Coral Sea had provided the first hints that the Japanese high-water mark had been reached, but it was the Battle of Midway that put up the sign for all to see."[106]

### Situation in the South Pacific

[edit]

The Australians and U.S. forces in Australia were initially disappointed with the outcome of the Battle of the Coral Sea, fearing the MO operation was the precursor to an invasion of the Australian mainland and the setback to Japan was only temporary. In a meeting held in late May, the Australian Advisory War Council described the battle's result as "rather disappointing" given that the Allies had advance notice of Japanese intentions. General MacArthur provided Australian Prime Minister John Curtin with his assessment of the battle, stating that "all the elements that have produced disaster in the Western Pacific since the beginning of the war" were still present as Japanese forces could strike anywhere if supported by major elements of the IJN.[107]

Because of the severe losses in carriers at Midway, the Japanese were unable to support another attempt to invade Port Moresby from the sea, forcing Japan to try to take Port Moresby by land. Japan began its land offensive towards Port Moresby along the Kokoda Track on 21 July from Buna and Gona. By then, the Allies had reinforced New Guinea with additional troops (primarily Australian) starting with the Australian 14th Brigade which embarked at Townsville on 15 May.[108] The added forces slowed, then eventually halted the Japanese advance towards Port Moresby in September 1942, and defeated an attempt by the Japanese to overpower an Allied base at Milne Bay.[109]

In the meantime, the Allies learned in July that the Japanese had begun building an airfield on Guadalcanal. Operating from this base the Japanese would threaten the shipping supply routes to Australia. To prevent this from occurring, the U.S. chose Tulagi and nearby Guadalcanal as the target of their first offensive. The failure of the Japanese to take Port Moresby, and their defeat at Midway, had the effect of dangling their base at Tulagi and Guadalcanal without effective protection from other Japanese bases. Tulagi and Guadalcanal were four hours flying time from Rabaul, the nearest large Japanese base.[110]

Three months later, on 7 August 1942, 11,000 United States Marines landed on Guadalcanal, and 3,000 U.S. Marines landed on Tulagi and nearby islands.[111] The Japanese troops on Tulagi and nearby islands were outnumbered and killed almost to the last man in the Battle of Tulagi and Gavutu–Tanambogo and the U.S. Marines on Guadalcanal captured an airfield under construction by the Japanese.[112] Thus began the Guadalcanal and Solomon Islands campaigns that resulted in a series of attritional, combined-arms battles between Allied and Japanese forces over the next year which, in tandem with the New Guinea campaign, eventually neutralized Japanese defenses in the South Pacific, inflicted irreparable losses on the Japanese military—especially its navy—and contributed significantly to the Allies' eventual victory over Japan.[113]

The delay in the advance of Japanese forces also allowed the Marine Corps to land on Funafuti on 2 October 1942, with a Naval Construction Battalion (Seabees) building airfields on three of the atolls of Tuvalu from which USAAF B-24 Liberator bombers of the Seventh Air Force operated. The atolls of Tuvalu acted as a staging post during the preparation for the Battle of Tarawa and the Battle of Makin that commenced on 20 November 1943, which was the implementation of Operation Galvanic.[114]

### New type of naval warfare

[edit]

A 13 May 1942 editorial cartoon from the Japanese English-language newspaper Japan Times & Advertiser depicts a dejected Uncle Sam joining John Bull in erecting grave markers for Allied ships which Japan had sunk, or claimed to have sunk, at Coral Sea and elsewhere.

The battle was the first naval engagement in history in which the participating ships never sighted or fired directly at each other. Instead, manned aircraft acted as the offensive artillery for the ships involved. Thus, the respective commanders were participating in a new type of warfare, carrier-versus-carrier, with which neither had any experience. In H. P. Willmot's words, the commanders "had to contend with uncertain and poor communications in situations in which the area of battle had grown far beyond that prescribed by past experience but in which speeds had increased to an even greater extent, thereby compressing decision-making time."[115] Because of the greater speed with which decisions were required, the Japanese were at a disadvantage as Inoue was too far away at Rabaul to effectively direct his naval forces in real time, in contrast to Fletcher who was on-scene with his carriers. The Japanese admirals involved were often slow to communicate important information to one another.[116]

Research has examined how commanders’ choices affected the battle’s outcome.[117] Two studies used mathematical models to estimate the impact of various alternatives.[118] For example, suppose the U.S. carriers had chosen to sail separately (though still nearby), rather than together. The models indicated the Americans would have suffered slightly less total damage, with one ship sunk but the other unharmed. However, the battle’s overall outcome would have been similar. By contrast, suppose one side had located its opponent early enough to launch a first strike, so that only the opponent’s survivors could have struck back. The modeling suggested striking first would have provided a decisive advantage, even more beneficial than having an extra carrier.

The experienced Japanese carrier aircrews performed better than those of the U.S., achieving greater results with an equivalent number of aircraft. The Japanese attack on the U.S. carriers on 8 May was better coordinated than the U.S. attack on the Japanese carriers. The Japanese suffered much higher losses to their carrier aircrews, losing ninety aircrew killed in the battle compared with thirty-five for the U.S. side. Japan's cadre of highly skilled carrier aircrews with which it began the war were, in effect, irreplaceable because of an institutionalised limitation in its training programs and the absence of a pool of experienced reserves or advanced training programs for new airmen. Coral Sea started a trend which resulted in the irreparable attrition of Japan's veteran carrier aircrews by the end of October 1942.[119]

The U.S. did not perform as expected, but it learned from its mistakes in the battle and made improvements to its carrier tactics and equipment, including fighter tactics, strike coordination, torpedo bombers and defensive strategies, such as anti-aircraft artillery, which contributed to better results in later battles. Radar gave the U.S. a limited advantage in this battle, but its value to the U.S. Navy increased over time as the technology improved and the Allies learned how to employ it more effectively. Following the loss of Lexington, improved methods for containing aviation fuel and better damage control procedures were implemented by the U.S.[120] Coordination between the Allied land-based air forces and the U.S. Navy was poor during this battle, but this too would improve over time.[121]

Japanese and U.S. carriers faced off against each other again in the battles of Midway, the Eastern Solomons, and the Santa Cruz Islands in 1942; and the Philippine Sea in 1944. Each of these battles was strategically significant, to varying degrees, in deciding the course and ultimate outcome of the Pacific War.[122]

The British radio interception station was at Colombo on Ceylon (Lundstrom). The U.S. mistakenly believed (in part due to erroneous transliteration of the characters of her name) that Shōhō was a previously unknown fleet carrier, Ryūkaku, with 84 aircraft (Holmes 1979, p. 70). A Japanese prisoner captured at the Battle of Midway informed the U.S. of the correct reading of the carrier's kanji and identified her as actually a light carrier (Lundstrom and Morison, p. 11). The Japanese apparently had not developed cipher codes for several of the islands in the Louisiade Archipelago and thus transmitted the island names in Katakana in the clear, making it easier for the U.S. to decipher the meaning of the messages (Holmes, p. 65). According to Parker (p. 21), MacArthur refused to believe the radio intelligence forecasts of the MO operation and did not acknowledge that the Japanese were attempting to invade Port Moresby until his reconnaissance aircraft actually sighted Japanese ships approaching the Louisiades and New Guinea in the first week of May.

TF 44's destroyers were Perkins, Walke, and Farragut. Chicago and Perkins sortied from Nouméa, with the rest coming from Australia. TF 44 was formerly known as the ANZAC Squadron and was assigned to MacArthur's command, under U.S. Rear Admiral Herbert Fairfax Leary (Lundstrom 2006, p. 133; Morison 1949, p. 15; Gill 1968, p. 34). Crace was senior in time in rank to Fletcher, but the Australian Commonwealth Naval Board assented to a request from King that Allied naval carrier forces in the area operate under the command of a U.S. flag officer (Lundstrom 2006, p. 133). The two oilers carried a total of 153,000 barrels (24,300 m3). TF 11 and TF 17 together burned about 11,400 barrels per day (1,810 m3/d) at normal cruising speed (15 kn (17 mph; 28 km/h)) (Lundstrom 2006, p. 135). The destroyer Worden accompanied Tippecanoe to Efate (ONI 1943, p. 11).

The order to maintain radio silence was to help conceal the presence of the forces from the enemy. Cressman states that Shima's force was sighted by Australia-based U.S. Army aircraft from Darwin, Glencurry, and Townsville (Cressman, p. 84), but Lundstrom says that the sighting was most likely by a coastwatcher in the Solomons. Morison (1949, p. 24) speculates that Fitch should have tried to inform Fletcher of his status via an aircraft-delivered message.

Gotō refueled his cruisers from the oiler Irō near the Shortland Islands on 5 May (Morison, p. 29). Also this day, Inoue shifted the four I-class submarines deployed in the Coral Sea to a point 150 nmi (170 mi; 280 km) northeast of Australia. None of the four would be a factor in the battle (Lundstrom 2006, p. 150). Since Takagi transited the Solomons during the night, the Nouméa-based U.S. Navy PBYs did not sight him (Lundstrom). Takagi's oiler was Tōhō Maru (Lundstrom).

Three B-17s from Port Moresby attacked Gotō's ships at 10:30 (Dull and Lundstrom, 2006). Gotō's ships were stationed about 90 nmi (100 mi; 170 km) northeast of Deboyne (D'Albas) to screen the left flank of Abe's and Kajioka's ships. Hackett ("IJN Furutaka") states four B-17s attacked Gotō's cruisers as they refueled at the Shortlands, causing no damage. Shōhō provided a combat air patrol over the invasion convoy until sundown (Morison, p. 32). The B-17s were from the 19th Bombardment Group (Morison, p. 31). Crave & Cate (1947, p. 448) and Gillison (1962, p. 523) state MacArthur's reconnaissance B-17s and B-25s from the 90th Bombardment Squadron provided Fletcher with sightings of the Japanese invasion forces, including Gotō's, on 4–5 May but the U.S. Navy, for unexplained reasons, has no record of having received these sighting reports. Gillison states that an RAAF reconnaissance PBY, commanded by Squadron Leader G. E. Hemsworth, was lost to enemy action near the Louisiades on 6 May.

The SBD's coding system was a board with pegs and holes to allow for rapid transmission of coded ship types. In Nielsen's case, the board was apparently not aligned properly (Cressman). Many of the sources are not completely clear on who exactly Nielsen spotted. Dull says he spotted the "Close Cover Force". Gotō's unit was called the "Distant Cover Force" or "Covering Group" and Marumo's was called the "Cover Force" or "Support Group". Millot and Morison state that Nielsen sighted "Marushige's" cruisers, not Gotō's. Marushige is presumably Marumo's cruiser force. Lundstrom (2006) states that Nielsen sighted Gotō.

Lundstrom says the B-17 sighting was 30 mi (30 mi; 48 km) from the cruisers but Cressman says 60 nmi (69 mi; 110 km). USACMH Vol. I (1994, p. 47) states that 10 B-17s were involved. At 11:00, TF17's combat air patrol (CAP) shot down a Kawanishi Type 97 from Tulagi (Lundstrom 2005b, pp. 196–197, Lundstrom 2006, p. 168). Ten F4Fs, 28 SBDs, and 12 TBDs were from Lexington and eight F4F, 25 SBD, and 10 TBD were from Yorktown (Cressman and Lundstrom 2006). The Kinugasa floatplane reported the launch of the U.S. strike force (Lundstrom 2006, p. 167). The three B-17s, after making their sighting report, bombed the Kamikawa Maru at Deboyne but caused only minor damage (Lundstrom 2006, p. 166).

The two Shōkaku scout aircraft, which lingered over the target area trying to assist the strike force in locating the U.S. ships, did not have sufficient fuel to return to their carrier and ditched on the Indispensable Reefs (see photo at right). The two crews were rescued by a Japanese destroyer, perhaps Ariake (Cressman, p. 92), on 7 May. Ariake sighted the two unrecovered Yorktown airmen from the Tulagi strike floating off Guadalcanal, but did not attempt to capture or kill them (Cressman, p. 92).

Several sources, including Hoyt, Millot, and Morison state that Neosho was attacked first by one, then three or more horizontal bombers around 09:05 before the main Japanese strike. Several Japanese torpedo aircraft dropped target designators near the oiler while the main strike force approached (Lundstrom 2006, p. 167). The dive bomber which crashed into Neosho was piloted by Petty Officer Second Class Shigeo Ishizuka with Petty Officer Third Class Masayoshi Kawazoe as the rear gunner/observer (Werneth, p. 66). Both were killed. Sixteen survivors from Sims were taken aboard Neosho, but one died soon after and another died after rescue four days later. The captain of Sims, Willford Hyman, was killed in the attack. One of Neosho's crewmen, Oscar V. Peterson, was posthumously awarded the Medal of Honor for his efforts to save the ship in spite of severe and ultimately fatal injuries suffered during the attack. At the time of the attack, Neosho's crew numbered 288 officers and men. Twenty are known to have died in the attack. A post-attack muster counted 110 personnel. The remaining 158 crewmen (including four officers) panicked and abandoned ship during or shortly after the attack. Of the men who abandoned ship, only four were eventually recovered; the rest died or vanished (ONI, pp. 48–53; Phillips, Hoyt, p. 130 & 192–193; Morison, pp. 35–37).
56. ^ Lundstrom 2005b, pp. 197–198 (says 1,500 yd (1,400 m) for the cruisers with Shōhō); Hoyt 2003, pp. 54–55; Cressman 2000, pp. 96–97; Millot 1974, p. 69; Dull 1978, p. 132; Lundstrom 2006, pp. 168–169; Henry 2003, pp. 54–56. Shōhō was preparing a strike of five torpedo planes and three Zeros belowdecks when the U.S. attack occurred. Three fighters – one Zero and two Type-96s – were aloft at the beginning of the attack, and three more – all Zeros – were launched as the attack commenced. Senshi Sōshō, Japan's War Ministry's official history, apparently specifies that Gotō's cruisers were 3,000 to 5,000 yards (2,743 to 4,572 m) away in order to warn the carrier of incoming aircraft, not to provide anti-aircraft support (Lundstrom 2006, p. 169 and a privately made sketch from the Senshi Sōsho). Japanese carrier defense doctrine at that time relied on maneuvering and fighter defenses to avoid air attack instead of concentrated anti-aircraft fire from escorting warships (Lundstrom).

Two of the downed SBD crews, one each from Lexington and Yorktown, were rescued. The lost pilot was VS-2's executive officer, Edward H. Allen. Dixon's phrase was quoted by Chicago Tribune war correspondent Stanley Johnston in a June 1942 article and subsequently requoted in most accounts of the Pacific War. Lexington's commanding officer, Captain Frederick C. Sherman, credited Dixon, commanding officer of squadron VS-2, with coining the word "flattop" which became standard slang for an aircraft carrier. Of the 203 Shōhō crewmen rescued, 72 were wounded. Shōhō's captain, Izawa Ishinosuke, survived. Sazanami was Shōhō's plane guard destroyer. One Zero and two Type 96 fighters were shot down during the attack. The remaining three Zeros ditched at Deboyne. One of these was flown by Kenjiro Nōtomi, commander of Shōhō's fighter group (Lundstrom).

U.S. intelligence personnel at Pearl Harbor and with TF17 believed that Japanese carriers Kaga and Kasuga Maru (Taiyō) might also be involved with the MO operation (Lundstrom 2006, pp. 196–197). According to Prados 1995, p. 309, the Japanese carriers' aircraft homing signals were detected by Yorktown's radio intelligence unit, led by Lieutenant Forrest R. Baird. Baird later stated that he pinpointed the location of Takagi's carriers, but Fletcher disbelieved the intelligence after learning that Lexington's unit, led by Lieutenant Commander Ransom Fullinwider, had not detected the homing signals (Prados).

The Type 1s, armed with Type 91 torpedoes, were from the IJN's 4th Air Group (4th Kōkūtai) and launched from Vunakanau airfield, Rabaul, at 09:15 escorted by 11 Zeros from the Tainan Air Group based at Lae, New Guinea (Lundstrom 2006, p. 171). Perhaps low on fuel, the Zeros turned back to Lae shortly before the bombers attacked Crace's ships. The Type 96s, each armed with a pair of 250 kg (550 lb) bombs, were from the IJN's Genzan Air Group and were originally assigned to bomb Port Moresby. All were operating as part of the 25th Air Flotilla under the command of Sadayoshi Yamada at Rabaul (Millot). One of the destroyed Type 1s was commanded by the formation leader, Lieutenant Kuniharu Kobayashi, who was killed. In addition to the four shot down at sea, one Type 1 crash-landed at Lae with serious damage and another ditched in the water at Deboyne with one dead crewman (Tagaya). Two crewmen in Chicago were killed and five wounded in the Japanese air attack (Hoyt, p. 68). According to Hoyt (p. 69) and Morison (pp. 20 & 39), MacArthur's air commander, Lieutenant General George Brett, later flatly denied any of his B-17s could have attacked Crace and prohibited further discussion of the incident. Millot and Gill incorrectly state the bombers were B-26s from the 19th Bomb Group based at Townsville, Australia. The three B-17s were led by Captain John A. Roberts (Lundstrom 2006, p. 172). Gillison (1962, p. 520) states MacArthur's fliers were not informed until after the battle was over that Allied warships were operating in the Coral Sea area. Salecker states that the B-17s attacked because they misidentified the Japanese bombers as U.S. B-25 or B-26 bombers. One of the three B-17s ran out of fuel on its return to base and was destroyed in the resulting crash, but the crew bailed-out and survived (Salecker, p. 181).

Two of the dive bombers returning from hitting Neosho crashed while attempting to land, but the crews apparently survived. Lieutenant Tamotsu Ema, commander of Zuikaku's dive bomber squadron, was one of the pilots selected for the evening strike mission.

Five of the downed torpedo bombers were from Zuikaku and the other two were from Shōkaku, as was the damaged torpedo plane. The dive bomber was from Zuikaku. The dead Japanese aircrews included the commanding officer of Zuikaku's torpedo bomber squadron, Lieutenant Yoshiaki Tsubota, and two division leaders, Lieutenants Yoshito Murakami (Zuikaku) and Tsutomu Hagiwara (Shokaku). The pilot of the damaged torpedo bomber was killed, so the middle-seat observer took over the controls and ditched near Shōkaku; both he and the rear gunner were killed. Two of the Wildcat pilots, Paul G. Baker from VF-2 on Lexington and Leslie L. B. Knox from VF-42 on Yorktown, were killed in action. Another CAP Wildcat, piloted by John Drayton Baker from Yorktown's VF-42, was apparently unable to locate TF-17 in the deepening gloom after the action and vanished without a trace (Lundstrom and Cressman). William Wolfe Wileman was one of the Wildcat pilots who survived the action.

Cressman says that some of the Japanese carrier aircraft did not land until after 23:00. Hoehling and Woolridge report that up to eight Japanese aircraft may have lined up to land on the U.S. carriers after sunset, but Lundstrom and Cressman explain that the number of aircraft was probably fewer than that. Millot states the postwar belief that 11 more Japanese aircraft were lost while landing on their carriers, but Lundstrom, citing Japanese sources, disagrees, stating that the 18 surviving aircraft all returned safely. In addition to his carriers' lights, Takagi's cruisers and destroyers illuminated the two carriers with their searchlights (Lundstrom 2006, p. 178).

Fletcher contemplated launching a carrier nocturnal attack or sending his cruisers and destroyers after Takagi's ships during the night, but decided it would be better to preserve his forces for battle the next day (ONI 1943, p. 19; Cressman, p. 101 and Lundstrom 2006, pp. 179–180). During the night, three Japanese Type 97 aircraft armed with torpedoes hunted Crace but failed to locate him (Lundstrom 2006, p. 182).

The carrier search aircraft included four from Shōkaku and three from Zuikaku. The floatplanes at Deboyne patrolled the area directly south of the Louisiades. Furutaka and Kinugasa joined the striking force at 07:50. After the previous day's losses, the striking force at this time consisted of 96 operational aircraft: 38 fighters, 33 dive bombers, and 25 torpedo bombers (Lundstrom 2006, p. 186).
72. ^ Lundstrom 2005b, pp. 221–222; Hoyt 2003, p. 75; Cressman 2000, p. 103; Woolridge 1993, p. 48; Millot 1974, pp. 82–83, 87; Dull 1978, p. 132; Lundstrom 2006, pp. 181–184. Twelve SBDs were assigned to the northern search area where the Japanese carriers were expected to be. The six SBDs assigned to the southern sector were to fly out only 125 nautical miles (232 km) and then assume close-in anti-submarine patrol duty upon their return to TF17. At this time operational aircraft strength for TF17 was 117, including 31 fighters, 65 dive bombers, and 21 torpedo planes (Lundstrom 2006, p. 183) Eight SBDs were assigned as close-in anti-submarine patrol, and 16 fighters, eight from each ship, to the CAP (Lundstrom 2006, p. 183). Around 01:10, Fletcher detached the destroyer Monaghan to try to find out what happened to Neosho. Monaghan searched throughout the day, but, basing her search on the erroneous coordinates in the tanker's last message, was unable to locate her and returned to TF17 that evening. While separated from TF17, Monaghan sent several messages to Nimitz and MacArthur, to allow TF17 to maintain radio silence (Cressman, p. 103; Hoyt 2003, p. 127; Lundstrom 2006, p. 181). Fitch was not actually notified by Fletcher he was in tactical control of the carriers until 09:08 (Lundstrom 2006, p. 186). According to Parker (2017, pp. 26–27), Fletcher was informed early on 8 May his Fleet Radio Unit located Japanese carriers northeast of his position.

Kanno, a warrant officer, was the middle-seat observer on a plane piloted by Petty Officer First Class Tsuguo Gotō. The radioman was Petty Officer Second Class Seijirō Kishida (Werneth, p. 67). Radio interception analysts in TF17 copied Kanno's messages and alerted Fletcher his carrier's location was known to the Japanese. Smith's report mistakenly placed the Japanese carriers 45 nmi (52 mi; 83 km) south of their actual position. An SBD piloted by Robert E. Dixon took over for Smith and stayed on station near the Japanese carriers to help guide in the U.S. strike until 10:45 (Morison).

An odd number of fighters took part in Lexington's attack because one of VF-2's Wildcats, piloted by Doc Sellstrom, was damaged during launch preparations and was forced to stay behind. TF17 recovered its returning scout aircraft between 09:20 and 10:50, and launched 10 SBDs for anti-submarine patrol at 10:12. The Japanese strike force included nine fighters, 19 dive bombers, and 10 torpedo planes from Shōkaku and nine fighters, 14 dive bombers, and 8 torpedo planes from Zuikaku. The fighters were Type 0s, the dive bombers were Type 99 kanbaku, and the torpedo planes were Type 97 kankō. Takahashi was in one of Shōkaku's kanbaku. By heading south, Takagi unwittingly moved his carriers into the range of the U.S. TBD torpedo planes, which otherwise would have been forced to turn back without participating in the attack (Lunstrom 2006, p. 187). Shortly after 10:00, two Yorktown CAP Wildcats shot down a Japanese Type 97 scout aircraft (Lundstrom 2006, p. 187).

The second hit was scored by SBD pilot John James Powers, who was shot down by a CAP Zero and killed during his dive. Tetsuzō Iwamoto was one of the CAP pilots airborne at the time, flying from Zuikaku. Another VB-5 SBD, crewed by Davis Chafee and John A. Kasselman, was shot down by a CAP Zero during the attack. During Yorktown's attack, a CAP Zero flown by Takeo Miyazawa was shot down by a Wildcat piloted by William S. Woolen, and a CAP Zero flown by Hisashi Ichinose was shot down by a Wildcat piloted by Elbert Scott McCuskey. Lundstrom states that both Zeros were from Shokaku. Hata states that Miyazawa was a member of Shōkaku's fighter group and that he died after shooting down a U.S. torpedo plane and then deliberately crashing his Zero into another (Hata & Izawa 1975, p. 42), although no TBDs were actually lost. Also flying in the Japanese CAP were future aces Yoshinao Kodaira and Kenji Okabe (Hata & Izawa 1975, pp. 286, 329). Aces Yoshimi Minami and Sadamu Komachi were members of Shōkaku's fighter group at this time (Hata & Izawa 1975, pp. 265, 281) but Hata does not say if they were with the CAP or the strike escort. Lundstrom states the former, detailing how Minami narrowly escaped being shot down by Woollen.

One of Lexington's bomber pilots was Harry Brinkley Bass, although his group was unable to locate the carriers. The three Wildcat pilots killed, from VF-2 squadron, were Richard S. Bull, Dale W. Peterson, and Richard M. Rowell (Lundstrom). The Japanese CAP claimed to have shot down 24 U.S. aircraft (Hata & Izawa 1975, p. 48).

Shōkaku's total losses were 108 killed and 114 wounded. The Japanese CAP fighter pilots claimed to have shot down 39 U.S. aircraft during the attack, at a cost of two Zeros destroyed and two damaged. Actual U.S. losses in the attack were two SBDs (from Yorktown) and three Wildcats (from Lexington). More U.S. aircraft were lost during the subsequent return to their carriers. The destroyers which accompanied Shōkaku's retirement were Ushio and Yūgure (Tully).

The Wildcats were at altitudes between 2,500 and 8,000 ft (760 and 2,440 m) when the Japanese aircraft, stacked between 10,000 and 13,000 ft (3,000 and 4,000 m), flew by. Kanno paused during his return to Shōkaku to lead the Japanese strike formation to within 35 nmi (40 mi; 65 km) of the U.S. carriers even though he was low on fuel.

The crews of the four SBDs, totalling eight airmen, were all killed (The crewmen's names are given in Cressman, p. 108. One was Samuel Underhill). The four torpedo planes sent after Yorktown were from Zuikaku. Two of the Zero escorts from Shōkaku were piloted by aces Ichirō Yamamoto and Masao Sasakibara (Hata & Izawa 1975, pp. 314, 317).

Screening Yorktown were cruisers Astoria, Portland, and Chester and destroyers Russell, Hammann, and Aylwin. Protecting Lexington were the cruisers Minneapolis and New Orleans and the destroyers Dewey, Morris, Anderson, and Phelps. Some participants thought Lexington might have been hit by as many as five torpedoes (Woolridge, p. 42 and Lundstrom 2006, p. 191). Two torpedo planes switched targets from Lexington to Minneapolis but missed (Lundstrom 2006, p. 191).

The four Lexington Wildcats were from VF-2 Squadron's 3rd Division under Lieutenant Fred Borries, Jr. The two Yorktown Wildcats were piloted by Vincent F. McCormack and Walter A. Haas from VF-42's 3rd Division. After losing their leader over Lexington, the last two Shōkaku dive bombers switched to attack Yorktown at the last minute. One of these was shot down by Albert O. Vorse (Lundstrom 2006, p. 191). Hoyt states that the bomb hit on Yorktown seriously wounded 26 men, several of whom (Hoyt does not specify the exact number) died later from their injuries. One of those killed by the bomb hit on Yorktown was Milton Ernest Ricketts. Three of Yorktown's boilers were shut down due to a flareback, but were back on line within 30 minutes (Cressman, p. 113). One bomb that hit Lexington wiped out a battery of United States Marine Corps anti-aircraft machine guns, killing six men (Hoehling, p. 82). Another did heavy damage to a 5-inch (127.0 mm) gun battery and wiped out its entire crew (Hoehling, pp. 90–92, see image at right, Lundstrom 2006, p. 191).

Hall was one of the SBD pilots who aggressively pursued the Japanese aircraft after they completed their attacks. A damaged SBD piloted by Roy O. Hale attempted to land on Lexington but was shot down by friendly anti-aircraft fire from the carrier and its escorts, killing Hale and his rear gunner (Lundstrom and Hoehling). Another damaged SBD bounced off Lexington's flight deck into the ocean, but its pilot, Frank R. McDonald, and rear gunner were rescued (Lundstrom and Hoehling). An SBD from VS-2 and two from VB-2 (Lexington) shot down the three Japanese torpedo planes, two from Shōkaku. The Japanese dive bomber was shot down by Walt Haas from Yorktown's VF-42. Two Wildcats from VF-2 (Lexington) piloted by Clark Franklin Rinehart and Newton H. Mason disappeared and their fates are unknown. A VF-42 (Yorktown) Wildcat piloted by Richard G. Crommelin was shot down by a Zero but Crommelin, unharmed, was rescued by the destroyer Phelps. A damaged Zero piloted by Shigeru Okura from Zuikaku ditched at Deboyne and Okura survived. A total of three Wildcats (two from VF-2 and one from VF-42) and six SBDs were lost defending TF17 from the Japanese strike. Kanno was killed by VF-42 pilots Bill Woolen and John P. Adams. Takahashi was killed by VF-42's Bill Leonard (Lundstrom). Lexington SBD pilot Joshua G. Cantor-Stone was also killed that day.

Clark was unable to find TF17 and disappeared without a trace. A TBD piloted by Leonard W. Thornhill ditched 20 nmi (23 mi; 37 km) from TF17; he and his rear gunner, seen entering their life raft, were not recovered, even though Fletcher sent the destroyer Dewey to look for them. William B. Ault, SBD pilot and commander of Lexington's air group, and another Lexington SBD piloted by John D. Wingfield from VS-2, were unable to find TF17 and disappeared. Ault's last transmission was, "From CLAG. OK, so long people. We got a 1000 pound hit on the flat top." (Lundstrom, p. 277). Another SBD piloted by Harry Wood ditched on Rossel Island and he and his rear gunner were later rescued. One Shōkaku Zero, piloted by Yukuo Hanzawa, successfully crash landed on Shōkaku (Hata & Izawa 1975, pp. 42–43). Nineteen Lexington aircraft were recovered by Yorktown (Millot 1974, p. 100). Parshall (p. 417) states that many of the jettisoned Japanese aircraft were not necessarily unserviceable, but were jettisoned to make way for less damaged aircraft because of a lack of sufficient deck-handling speed and skill by Zuikaku's crew.

Fletcher initially proposed sending the damaged Lexington to port for repairs and transferring that ship's aircraft to Yorktown to continue the battle, but Fitch's 14:22 message changed his mind. Separate U.S. aircraft, both carrier and land-based, had apparently sighted Zuikaku twice but were unaware that this was the same carrier (Hoyt, p. 133).

As the fires raged on Lexington, several of her aircrews requested to fly their aircraft to Yorktown, but Sherman refused (Lundstrom 2006, p. 560). The names of those killed from Lexington's crew, including from the air squadrons, are recorded in Hoehling 1971, pp. 201–205. One of those killed was Howard R. Healy. Hoyt, Millot, and Morison give the coordinates of the sinking as 15°12′S 155°27′E﻿ / ﻿15.200°S 155.450°E﻿ / -15.200; 155.450. Assisting Lexington during her travails were Minneapolis, New Orleans, Phelps, Morris, Hammann, and Anderson. Portland, Morris, and Phelps were the last to leave Lexington's final location (Lundstrom 2006, pp. 197, 204). Gillison (p. 519) states that eight B-26 bombers from Townsville sortied to attack Inoue's forces but were unable to locate the Japanese ships.

On 9 May, Yorktown counted 35 operational aircraft: 15 fighters, 16 dive bombers, and seven torpedo planes (Lundstrom 2006, pp. 200, 204). Fletcher stationed Russell and Aylwin 20 nmi (23 mi; 37 km) astern as radar pickets to warn of any Japanese pursuit (Lundstrom 2006, p. 204). On 9 May, a Yorktown SBD on scout patrol sighted what it thought was a Japanese carrier 175 nmi (201 mi; 324 km) from TF17. Yorktown dispatched a strike force of four SBDs, which could not locate the target. It was later determined the scout probably sighted the Lihou Reef and Cays (Lundstrom 2006, pp. 205–6). Fourteen U.S. Army B-17s from Townsville also responded to the erroneous report. During the false alarm, an SBD crashed in the sea; the crew was rescued. On 11 May, Fletcher dispatched cruisers Minneapolis, New Orleans, and Astoria with three destroyers under Kinkaid to rendezvous with Halsey's TF16 near Efate after a brief stop at Nouméa (Lundstrom 2006, p. 205). Gillison (1962, p. 527) reports that Japanese float fighters from Deboyne attacked and seriously damaged an RAAF reconnaissance PBY, from 11th Squadron, commanded by Flying Officer Miller, on 9 May.

The invasion convoy returned to Rabaul on 10 May. Takagi intended to complete the delivery of the Tainan Zeros to Rabaul and then provide air support for the RY operation before Yamamoto ordered the ship back to Japan. After further repairs to battle-damaged aircraft, on 9 May Zuikaku counted 24 fighters, 13 dive bombers, and eight torpedo planes operational. Takagi's scout aircraft sighted the drifting Neosho on 10 May, but Takagi decided the tanker was not worth another strike (Lundstrom 2006, p. 207). Takagi completed delivery of the Zeros to Rabaul after turning back on 10 May. Matome Ugaki, Yamamoto's chief of staff, stated that he initiated and sent the order in Yamamoto's name to Takagi to pursue the Allied ships (Chihaya, p. 124). Four U.S. Army B-25 bombers attacked Japanese floatplanes moored at Deboyne on 10 May, but apparently caused no damage. The bombers did not see Kamikawa Maru present (Gillison 1962, p. 527).
92. ^ ONI 1943, p. 52; Millot 1974, p. 108; Morison 1949, pp. 35–37. The PBY was from Tangier's air group. The U.S. destroyer Helm recovered four more Neosho crewmen from a drifting raft (Morison coords: 15°25′S 154°56′E﻿ / ﻿15.417°S 154.933°E﻿ / -15.417; 154.933; ONI coords: 15°16′S 155°07′E﻿ / ﻿15.267°S 155.117°E﻿ / -15.267; 155.117) on 14 May, the sole survivors of the group which abandoned ship in panic on 7 May (ONI, p. 53; Millot 1974, p. 108; and Morison, p. 36). Hoyt incorrectly says that it was U.S. destroyer Phelps who recovered the final four survivors (Hoyt (2003, pp. 192–193)). Two more Neosho crewmembers died on 13 May aboard Henley from their injuries (Hoyt) and one of the four rescued from the ocean by Helm died soon after rescue (Morison, p. 36).

The RY invasion force included one light cruiser, one minelayer, two destroyers, and two transports (Lundstrom). Takagi's cruisers and destroyers provided distant cover to the north. Ocean and Nauru were later occupied by the Japanese without opposition on 25–26 August and held until the end of the war (Millot and Morison). Yorktown refueled from an Australian armed merchant cruiser HMAS Kanimbla at Tongatabu on 16 May, and then – along with her escorts – from the oiler USS Kanawha on 18 May (Lundstrom 2006, pp. 207 & 216). The initial U.S. intelligence on Yamamoto's upcoming operation indicated an attack on Oahu, but around 17 May, Midway emerged as the probable target (Lundstrom 2006, pp. 208 & 212).

Shōkaku almost capsized because she had to steam at high speed during the trip to Japan to avoid attacks from the U.S. submarines. The high speed caused her to take on water through her damaged bow. Four submarines— Gar, Greenling, Tautog, and Grampus – were stationed off Truk, and four more – Drum, Grenadier, Triton, and Pollack – between Truk and Japan. Triton sighted a carrier, believed to be Shōkaku, at 6,700 yd (6,100 m) but was unable to close and attack (Holmes 1979, p. 74; Blair, pp. 230–233).
