The Cisplatine War[b] was an armed conflict fought in the 1820s between the Empire of Brazil and the United Provinces of the Río de la Plata over control of Brazil's Cisplatina province. It was fought in the aftermath of the United Provinces' and Brazil's independence from Spain and Portugal, respectively, and resulted in the independence of Cisplatina as the Oriental Republic of Uruguay.

In 1816, the United Kingdom of Portugal, Brazil and the Algarves carried out an invasion of the Banda Oriental and, after defeating the local resistance led by José Gervasio Artigas, annexed it under the name of Cisplatina. After Brazil's independence in 1822, Cisplatina remained as part of Brazil. Wishing to gain control of the region, the United Provinces sent a diplomatic mission to Brazil in 1823 to negotiate a peaceful Brazilian withdrawal, but it failed. In 1825, a group of patriots known as the Thirty-Three Orientals, supported by the Argentine government and led by Juan Antonio Lavalleja, launched a rebellion against Brazil. On 25 August of that year, in the Congress of Florida, they declared Cisplatina's independence from Brazil and its unification with the United Provinces. After a series of initial skirmishes, they defeated the Brazilians at the battles of Rincón and Sarandí, prompting the Argentine Congress to proclaim Cisplatina reintegrated into the United Provinces on 25 October. In response, Brazil declared war on the United Provinces on 10 December 1825 and imposed a naval blockade on the River Plate.

The United Provinces managed to occupy the Uruguayan countryside with the help of the local insurgents, however, its forces never managed to capture Montevideo and Colonia del Sacramento or penetrate deeply into Brazilian territory. Likewise, the Brazilians did not manage to regain control of the countryside or achieve a decisive victory in order to repel the Argentines, being defeated at the battle of Ituzaingó. Thus, the war on land reached an impasse. At sea, however, the Brazilian Navy obtained better results, despite the Argentine resistance, whose small fleet, led by Irish-born admiral William Brown, was mostly destroyed.

The economic burden and internal political disputes caused by the war in both states, especially the Brazilian naval blockade and the impasse on land, led both countries to start peace negotiations. In 1827, the Argentine minister plenipotentiary Manuel José García signed a peace treaty with Brazilian representatives, recognizing Brazil's sovereignty over Cisplatina and agreeing to pay Brazil a war indemnity. The treaty was rejected by Argentine president Bernardino Rivadavia, but its terms generated enormous backlash forcing the president to present his resignation. Manuel Dorrego was then elected to succeed him and continue the war. The conflict continued until 27 August 1828, when Argentine and Brazilian representatives, under British mediation, signed the Preliminary Peace Convention of 1828, by which Cisplatina would become an independent state and hostilities would cease.

After the war, tensions in Argentina between the Federalists and the Unitarians increased. Manuel Dorrego, a Federalist, was deposed and executed by Juan Lavalle and the country fell into a civil war. In Brazil, the war's financial cost, aggravated by the damage done to Brazilian trade by Argentine corsairs, and the loss of Cisplatina, added to the internal political disputes surrounding emperor Pedro I, which ultimately led him to abdicate the throne in favour of his 5-year-old son Pedro II in 1831, ushering the regency period.

## Background

[edit]

### Colonial disputes

[edit]

Following the South American wars of independence, the region known as the Banda Oriental became a point of contention between the Empire of Brazil and the United Provinces after Brazil's independence in 1822.[5] This dispute was inherited from the Portuguese and Spanish colonial empires, whose borders in the River Plate basin had never been settled.[6] It began in 1679, when the Portuguese crown, which had always considered the River Plate as Brazil's natural southern border, ordered Manuel Lobo [pt], the governor of the Captaincy of Rio de Janeiro, to found the fortress town of Colônia do Sacramento, in an easily defensible peninsula with a natural harbour, on the right bank of the river, right in front of Buenos Aires, which he effectively did in 1680.[7] By expanding into the River Plate basin, the Portuguese wanted to secure access to the continent's interior and also divert the smuggling of silver from Upper Peru away from Buenos Aires.[8]

The Spaniards, wishing to solidify their control over the region, also founded a colony on the opposite bank of the river in 1724, when Bruno Mauricio de Zabala founded the town of Montevideo.[9] After centuries of wars and settling attempts between the two empires, Colônia do Sacramento finally became a Spanish possession by the 1801 Treaty of Badajoz.[10]

With the outbreak of the 1810 May Revolution in Buenos Aires and the Argentine struggle for independence that ensued, Montevideo, under the command of viceroy Francisco Javier de Elío, remained loyal to Spain.[11] The Primera Junta of Buenos Aires then set out to subdue Montevideo and Elío, who, finding himself without support from Europe, requested assistance from Carlota Joaquina, the Spanish wife of Portuguese prince regent John of Braganza.[12] The Portuguese crown, which had fled to Brazil in 1808 after the French invasion of Portugal, then took the opportunity to invade the Banda Oriental in 1811.[13] An army named "Peacekeeping Army of the Banda Oriental" was assembled and command was given to Diogo de Sousa [pt], who had orders to help Elío.[14] Diogo de Sousa then led the troops into the Banda Oriental, but a few months later, on 20 October 1811, Elío signed the Treaty of Pacification with the First Triumvirate, which had succeeded the Primera Junta, and so the Argentines, led by José Rondeau, lifted the siege on Montevideo and left the Banda Oriental.[15] Likewise, the Portuguese signed an armistice with Buenos Aires on 26 May 1812 and also left the region.[16]

In this struggle for control over the region, José Gervasio Artigas, a native of the Banda Oriental who had defeated the Spanish at the battle of Las Piedras in 1811, opposed the treaty; Artigas left the Banda Oriental with 16 thousand people, in what became known as the Oriental Exodus [es], and continued to fight against Spanish rule.[17] In 1814, Artigas, who had fought for independence alongside Buenos Aires troops since 1810, finally defeated the last Spanish forces in the region.[18] Despite receiving military assistance from Buenos Aires in the independence war, Artigas opposed the Buenos Aires elites' intention of centralizing power and resisted their attempts to take control of the Banda Oriental, defeating Manuel Dorrego at the battle of Guayabos [es] in 1815 and forming the League of the Free Peoples.[19] This league was based on federalism and social reform, which gained him the support of the poor peoples of the countryside; thus, Artigas became an obstacle to Buenos Aires' political ambitions.[10]

Artigas also opposed Portuguese intentions of asserting control over the region, and attacked the neighboring Brazilian province of Rio Grande do Sul near Quaraí.[20] His influence was also felt in the north, inhabited by Brazilians.[10] In the account of John Parish Robertson, the Banda Oriental fell into "the most unbridled disorder and horrible anarchy" and Artigas' name became "synonymous with bandit, murderer and thief";[21] this was the pretext now king John VI needed to once again invade the region in 1816.[20] The new invasion, led by Carlos Frederico Lecor, was instigated and unopposed by Buenos Aires, who feared Artigas.[22][c] The invading Luso-Brazilian forces repeatedly defeated Artigas and his men, with Lecor conquering Montevideo on 20 January 1817.[23] Artigas still unsuccessfully tried to resist, being finally defeated at the battle of Tacuarembó in 1820; with no hopes of continuing the resistance, he went into exile in Paraguay, where he spent the rest of his life as a prisoner of Paraguayan dictator Rodríguez de Francia.[24]

### Brazilian rule and failure of negotiations

[edit]

On 31 July 1821, the Montevideo cabildo, with representatives from all of the Banda Oriental, approved its incorporation into the United Kingdom of Portugal, Brazil and the Algarves as a province under the name of Cisplatina.[25][d] The following year, when prince Pedro of Branganza openly rebelled against the Portuguese Cortes, the Brazilian government juntas in the provinces gradually joined the independence cause, with the exception of Cisplatina, whose junta, led by Portuguese-born Álvaro da Costa [pt], voted to remain loyal to Portugal.[26][e] Brazilian patriots, loyal to prince Pedro and under the command of Carlos Frederico Lecor, then besieged and blockaded the Portuguese troops garrisoned in Montevideo, finally defeating them in 1824.[27]

The local population was divided on the matter; many notable natives of the province, such as Fructuoso Rivera and Juan Antonio Lavalleja, joined Lecor against the Portuguese, while others, such as Manuel Oribe, sided with Portugal; the towns and villages of the countryside, such as Colônia do Sacramento, San José, Cerro Largo and Maldonado, had also joined the Brazilian cause.[28] Thus, once the Portuguese were defeated and left to Lisbon, the Cisplatina province remained as part of the Empire of Brazil.[29]

Following the United Province's recognition of Brazil's independence on 25 June 1823, the country immediately began diplomatic talks with the Empire regarding Cisplatina, which the Argentine government considered theirs and wanted to gain possession of.[30] In 1823, the Argentines sent José Valentín Gómez [es] to the Brazilian court in Rio de Janeiro in order to negotiate a peaceful Brazilian withdrawal from the region.[31] The Argentine diplomatic mission made a series of proposals and, after receiving no response from the Brazilian government, demanded a reply in February 1824.[32] The answer was given on 6 February 1824, in which the Imperial government promptly rejected any negotiations regarding the cession of Cisplatina, concluding its note by declaring:[33]

> Therefore, on these important considerations, the Government of His Imperial Majesty can not enter with Buenos Aires on a negotiation which has for its fundamental basis the cession of the Cisplatine State, the inhabitants of which it can not abandon.

Emperor Pedro I of Brazil, who had been informed of the situation in Cisplatina by Lecor, believed the natives of the province wanted to remain as part of the Empire; however, Lecor had surrounded himself with people who were sympathetic to Brazil, which prevented him from knowing the true intentions of the province's inhabitants.[34] Likewise, after the Brazilian patriots defeated the Portuguese and entered Montevideo, the locals swore the Brazilian Constitution on 10 May 1824, by which Cisplatina would become part of Brazil.[35][f] This situation gave off the impression the inhabitants of the province wanted to be part of the Empire.[31] In reality, however, this was not the case: apart from Montevideo and other small cities along the coast, all the countryside, where Artigas' influence was still strong, wished for independence, with the locals disguising their intentions.[36][g] According to Argentine historian Ángel Carranza [es], the people and the press in Argentina "ardently clamored for the vindication of the usurped property".[37]

### The Uruguayan rebellion

[edit]

#### Landing of the Thirty-Three Orientals

[edit]

Main article: Thirty-Three Orientals

The landing of the Thirty-Three Orientales [Uruguayans] on Agraciada beach, by Josefa Palacios

When news of the Argentine diplomatic mission's failure reached Montevideo, the locals, including various of the notable leaders who had previously fought alongside the Brazilians against the Portuguese, started to conspire against Brazilian rule, wishing to unite with the United Provinces and forming a secret society named Caballeros Orientales.[38] The conspiracy was discovered by Lecor and some of the more prominent conspirators had to flee to Buenos Aires.[38][h] Among the conspirators, who numbered more than two hundred people, was Fructuoso Rivera, who was a colonel in the Brazilian Army. Despite having distinguished himself in the service of the Empire and having received several promises of career advancement, Rivera decided to revolt, but continued to disguise his intentions from the Brazilian Court.[39][i]

On 19 April 1825, a group of 33 men known as the Treinta y Tres, or the Thirty-Three,[j] led by Juan Antonio Lavalleja, left Buenos Aires, crossed the Uruguay River and landed on Agraciada beach with arms and ammunition, starting the rebel movement against the Empire of Brazil; the action had Rivera's knowledge and collusion.[40] After landing, Lavalleja and his men set out in search of recruits.[41] The next day, the patriots, already numbering more than 200 men, marched to Soriano and defeated the small garrison there, which was commanded by Julián Laguna [es], who joined them.[42] People from every corner of the province began to take up arms and present themselves to the patriots.[43] According to John Armitage, a foreign observer present at the time, the insurgents were few in number, but superior to their opponents when on horseback, also having "a perfect knowledge of the face of the country".[41]

#### Rivera's defection and first actions

[edit]

When news of Soriano's fall reached Lecor, he ordered Rivera to attack it. After leaving Colonia del Sacramento to confront the rebels, Rivera was imprisoned by them without offering resistance, defecting to their side on 27 April.[44][k] On 1 May, Rivera, whose defection was still ignored in the Brazilian Army, went from Monzon to San José, where he met Brazilian colonel Vicente Rodrigues Borba, who, having arrived there with troops from Curitiba and São Paulo, was to join forces with Rivera. Unaware of Rivera's defection, Borba went to meet him, at which time he and his entire column of 300 men were captured by Lavalleja.[45]

The Oath of the Thirty-Three Orientals, by Juan Manuel Blanes

Upon learning of Rivera's defection, the Brazilian government sent two thousand men and a fleet under admiral Rodrigo Ferreira Lobo to the River Plate in July 1825 in order to request the Argentines to abstain from further aiding the rebels and to recall "their subjects", otherwise his imperial majesty would "repel force by force".[46] The Argentine government replied that it had no part in the rebellion and that "the supplies furnished from Buenos Aires had been bought either with the money, or on the credit, of private individuals in the stores of the city, which were open to all alike, whether friends or enemies".[47] Despite this, they were covertly supporting the rebels and, as time passed, it became increasingly apparent that the message was insincere.[48] In Carranza's words, the insurgents' "crusade" was "generously supported by donations from Argentines and Orientals [Uruguayans]".[49]

On 14 July, the Uruguayan patriots installed a provisional government in Florida, which was headed by Lavalleja. By now their numbers had increased considerably: Lavalleja, commander of the army, was at the head of 1,000 men. Rivera commanded an equal force in Durazno, while Manuel Oribe and Quirós commanded 300 men each.[50] The Uruguayans then laid siege to Colonia del Sacramento and Montevideo. On 15 July, Brazilian colonel Vasco Antunes Maciel routed the besiegers at Colonia. Three days later, Oribe attacked Montevideo at night, but was repelled. On 17 August, a new battle took place near Colonia del Sacramento, when colonel João Ramos, at the head of 300 Brazilians, fought against 400 Uruguayans, who, after a fierce combat, retreated with considerable losses. On 22 August, Rivera attacked the town of Mercedes with 500 men, being repelled. According to David Carneiro, the patriots' goal was always to fight on open field due to the superiority of their cavalry, but, whenever that was not the case, or when they were not in large numerical advantage, they were defeated.[51]

#### Rincón and Sarandí

[edit]

On 25 August 1825, in an assembly [es] gathered in Florida, the Uruguayans declared their independence from Brazil and their union with the United Provinces.[52] The declaration's goal was to compel the Argentine government to take definitive action.[53] Brazilian general José de Abreu, who had entered the province's countryside in June 1825 with 1,300 men, decided to take the initiative. He ordered Bento Manuel Ribeiro to march towards Rivera and attack him whenever he was found. Rivera, in turn, wanted to avoid any encounter with the Brazilians, but was found by Ribeiro, who defeated him at Puntas del Águila on 4 September 1825.[54] According to Carneiro, the victory made Ribeiro too confident and anxious: after defeating Rivera, he marched to Montevideo in order to convince Lecor, who passively watched everything, to take the initiative.[55] Taking advantage of Ribeiro's absence, Rivera decided to attack the Brazilian camp at Rincón de las Gallinas and take the more than six thousand horses guarded there. On 24 September, he defeated the small garrison and, when preparing to leave, was informed that two Brazilian cavalry units were approaching the camp. Rivera then ambushed and defeated each of them separately.[56]

Once convinced by Bento Manuel to go on the offensive, Lecor devised a plan to defeat the patriots separately and ordered Bento Manuel to reconnoitre the countryside.[57] Bento Manuel left Montevideo for Minas on 1 October with 1,150 cavalrymen in order to join forces with Bento Gonçalves and his 354 men. After the junction, they were to march towards Lavalleja and fight him before he could join forces with Rivera. The two Uruguayan leaders managed to join forces, however, and together they numbered more than two thousand men.[58]

### The outbreak of war

[edit]

The Brazilian declaration of war, signed by the Viscount of Santo Amaro[l]

With the rebellion gaining traction after the victories at Rincón and Sarandí, the Argentines began mobilizing for war.[59] The Congress of the United Provinces approved, on 11 May 1825, a law that provided for the creation and maintenance of an army. This army, created by Juan Gregorio de las Heras on 13 May 1825, was named "Observation Army" and had a predicted strength of 8,000 men.[60] Command was given to general Martín Rodriguez, who positioned it along the Uruguay River without any notification to the Brazilian government.[61] This act caused the protest of the Brazilian consul in Buenos Aires, Antônio José Falcão da Frota [pt], who had been appointed for the office that same month.[62]

On the night of 20 October 1825, the population in Buenos Aires took to the streets and attacked the Brazilian consulate shouting death to the emperor of Brazil and insulting the Brazilian consul, to which the Argentine government refused to give any satisfaction.[63] A few days later, on 28 October, Frota wrote his last report to the Brazilian government, declaring that the United Provinces' Congress had already decided on war. Fearing for his own safety, he left Buenos Aires and returned to Brazil.[64]

The Argentine Congress proclaimed the Cisplatina province reintegrated into the United Provinces on 25 October 1825, declaring that it would help the insurgents against Brazil by all means;[65] this decision was communicated to the Minister of Foreign Affairs of Brazil by means of a note on 3 November.[66] The following day, the Argentine government broke off diplomatic relations with Brazil, claiming that the Imperial Navy had engaged in acts of hostility in the River Plate.[67] Faced with this situation, the Empire of Brazil then responded by formally declaring war on the United Provinces on 10 December 1825, with admiral Rodrigo Lobo declaring "all the ports of the Republic in a state of blockade" eleven days later, on 21 December.[68] In order to effectively fight Brazil, the Argentine Congress then created the central executive power and elected Bernardino Rivadavia as the country's first president.[69]

## Opposing forces

[edit]

### Brazilians

[edit]

The Brazilian ship of the line Pedro I, by Edoardo De Martino

According to Brian Vale and Jorge Luis Toscano, Brazil was the largest naval power in the Americas at the time.[70] Toscano estimated the Brazilian fleet at no less than 65 large warships for a total of 690 guns in 1825, also counting 31 small armed packet boats and transport vessels, noting that it had doubled in size in the three years after the country's independence war by the purchase or incorporation of ships that had been captured by lord Thomas Cochrane from Portugal during the conflict.[71] Apart from purchasing ships, the imperial government also ordered the construction of new ones in local shipyards: two frigates, two corvettes and several gunboats and yachts.[72]

In Hélio Leôncio Martins' estimate, the Imperial Brazilian Navy was the strongest force Brazil could rely on, numbering 121 ships including two ships of the line, Pedro I and Príncipe Real, 8 frigates, 7 corvettes, 1 lugger, 17 brigs, 24 schooners, 33 gunboats, and other vessels.[73] Apart from these vessels, the Brazilian fleet also included merchant ones that had been armed and converted into warships.[71] Its quality varied, however; the frigates were no older than eight years, but the corvettes and brigs included ships from the Napoleonic Wars, such as Itaparica, Liberal and Cacique, to new ones built in North America, such as Maria da Gloria and Maceió.[71] The ships of the line, Pedro I and Príncipe Real, built in 1763 and 1771, respectively, were old and in poor condition, with the latter serving only as a prison ship while the former, despite still being in active service during the war, was in serious need of repairs.[74]

Brazil's naval policy became the subject of criticism for the government's opposition, which were repeated by foreign observers. The former, wanting to harm the emperor's ministers, described the navy as a "naval police", saying that, instead of the large and heavy frigates bought by the government, it would have been better to acquire low draft schooners, better suited for navigation in the shallow waters of the River Plate.[72] For John Armitage, the desire of "ostentation" and to show off an "exalted idea" of its naval power to foreign nations had led Brazil to purchase and build heavy vessels, unsuited for war in the River Plate.[75] Armitage also opined that "swift-sailing vessels would not only have been more easily equipped, but also more appropriate to the actual exigencies of the country".[76] This was also Gustavo Barroso's opinion, for whom the Brazilian fleet was "abundant, but inadequate", as its ships "were not suited to our people, our service and the war against [our] neighbours inside their home".[77] In turn, Toscano argued that these criticisms were unjustified, remarking that, for a country like Brazil, with a large coast and sea trade routes to defend, having a balanced navy with both large and small vessels would be ideal; Toscano also pointed out that John Armitage's remarks were "accepted without criticism in its nominal value by many historians".[72]

When the war broke out in December 1825, the Brazilian naval forces in the River Plate consisted of the frigate Tétis, the corvette Liberal, 2 brigs, a barque, 12 schooners, and 8 gunboats; the same fleet that, under the command of Pedro Nunes, had fought against the Portuguese during Brazil's independence war and also against Artigas in 1820.[78] This squadron was promptly reinforced by two frigates, Imperatriz and Paula, two corvettes, Itaparica and Maceió, one brig and other smaller vessels.[78]

### Argentines

[edit]

In Jorge Toscano's words, when compared to Brazil's maritime power, the Argentine Navy was "insignificant and consisted of little more than a handful of small ships left aside since the independence campaign", also remarking that the sight of admiral Lobo's fleet anchored in front of Buenos Aires was a constant reminder of the country's vulnerability.[79] As a result, measures began to be taken in mid-1825: the new Argentine navy minister, Marcos Balcarce [es], created the navy's structure and appointed commanders José Zapiola and Benito de Goyena [es]; these, in turn, established the payments, rations and uniforms, and also published privateering rules. Balcarce also sought to increase the fleet's size.[80] According to Angel Carranza, at the beginning of 1826 the Argentine fleet numbered 16 ships: a corvette, two brigs, a ketch, and 12 gunboats.[81]

According to Alexandre Boiteux, upon creating their navy, "the Argentines did so not only in accordance with their financial resources, but also with the hydrographic conditions of the theater of operations: robust medium-draft ships, sailboats, well equipped, easily manoeuvrable".[77] In Carranza's view, the Argentine fleet consisted of "some materially weak vessels, but that became respectable and effective by the strong spirit of their crews".[82]

## Conflict

[edit]

### The war at sea

[edit]

The two navies which confronted each other in the Río de la Plata and the South Atlantic were in many ways opposites. The Empire of Brazil was a major naval power consisting of 96 warships, large and small, an extensive coastal trade and a large international trade carried on mostly in British, French and American ships. The United Provinces had similar international trading links but had few naval pretensions. Its navy consisted of only half a dozen warships and a few gunboats for port defence. Both navies were short of indigenous sailors and relied heavily on British—and, to a lesser extent—American and French officers and sailors, the most notable of which were the Irish born admiral William Brown, and the commander of the Brazilian inshore squadron, the English commodore James Norton.[83]

The strategy of the two nations reflected their respective positions. The Brazilians immediately imposed a blockade on the Río de la Plata and the trade of Buenos Aires on 31 December 1825,[84] while the Argentines attempted to defy the blockade using Brown's squadron while unleashing a swarm of privateers to attack Brazilian seaborne commerce in the South Atlantic from their bases at Ensenada and more distant Carmen de Patagones.[85] The Argentines gained some notable successes—most notably by defeating the Brazilian flotilla on the Uruguay River at the Battle of Juncal and by beating off a Brazilian attack on Carmen de Patagones. But by 1828, the superior numbers of Brazil's blockading squadrons had effectively destroyed Brown's naval force at the Monte Santiago and was successfully strangling the trade of Buenos Aires and the government revenue it generated.[86]

#### Brazilian blockade

[edit]

Brazilian fleet blockading Buenos Aires

According to Brian Vale, "it was inevitable that Brazil's principal weapon in the struggle would be a naval blockade", given the country's naval power. Moreover, ever since the United Provinces' independence from Spain, Buenos Aires had become a centre of trade, which, being carried out mostly by British, American, and French ships, totalled a yearly sum of 2 million pounds in 1825. It was, therefore, an obvious target.[87] Following Brazil's declaration of war on 10 December 1825, admiral Rodrigo Lobo, commander of the Brazilian fleet in the River Plate, declared the blockade on 21 December, giving neutral vessels fourteen days to leave. News of the blockade only reached Buenos Aires ten days after its declaration, however, and a wave of panic ensued. Woodbine Parish, the British consul in the city, protested that it would be impossible for neutral vessels to leave in time, and so admiral Lobo agreed to postpone the beginning of the blockade to 31 January 1826.[88]

Rodrigo Lobo's initial declaration stated that "all of the ports of the republic" were in a state of blockade.[89] It caused different reactions from foreign powers. The United States view on blockades had been expressed before the war had begun, when Condy Raguet, the U.S. consul in Rio de Janeiro, wrote an extensive note to the Brazilian court detailing his government's position after being notified of the blockade on 6 December.[90] Likewise, the American consul in Buenos Aires, colonel John Forbes, protested and accused Brazil of conducting a "paper" blockade for breaking the requirements of presence and continuity, since Lobo's fleet had made frequent returns to Montevideo for long periods.[91]

The Americans held the view that a blockading force should not only be near the ports, but also in sight. They also argued that Brazil could not legitimally claim to be blockading Patagonia's southern coast when a single corvette was present there. In May, admiral Lobo conceded and agreed to limit the blockade to the River Plate's estuary.[92] The United Kingdom, on the other hand, accepted the Brazilian position. As a naval power itself, it was not in Britain's interests for blockades to be hampered by excessive rules. The British government ordered its diplomatic posts to observe the blockade and refused requests for intervention made by its nationals to the Foreign Office.[92]

In May 1826, Rodrigo Lobo was replaced by admiral Pinto Guedes, who reinvigorated the blockade, causing an enormous increase in the number of vessels seized, which motivated protests from Britain, France and the United States.[93] In November Raguet announced that the United States refused to accept the legality of the blockade; the French ambassador was also instructed not to recognize it, unless Brazil released all French prizes and paid an indemnity. Only Britain continued to recognize it. With foreign patience waning, the Brazilian government backed down: on 26 November 1826, Guedes was ordered only to seize neutral vessels that were attempting to run the blockade after individually warning each one of them. The changes to the blockade's rules made the risk worth taking, and so the number of vessels reaching Buenos Aires, most of which were American, increased.[94] Disappointed with his government's decision, Guedes declared: "I feel not the least repugnance to act fairly to the subjects of His Britannic Majesty, but no-one is ignorant of the mischief which citizens of the United States have done by taking advantage of the obstructions placed in the way of this squadron".[95]

##### Economic impacts

[edit]

The economy of Buenos Aires, which was based on the export of cattle, was dependent on the city's port due to the customs revenues it generated. In Roberto Schmit's words, with the blockade, a negative economic cycle began, and production and trade plummeted.[96] When admiral Pinto Guedes replaced Rodrigo Lobo, the Imperial Navy slowly began to strangle the trade from Buenos Aires. According to Vale, only two vessels managed to enter the city's port in the second half of 1826, ruining the country's finances. That year, customs revenues fell to 81,900 pounds from 429,300 in the previous year, and the price of imported commodities more than doubled.[97] Bonds issued for public and private investments lost their value and inflation quickly went up, as the government used its metal reserves to finance the war, leaving fiat money unbacked. The population's purchasing power decreased and several businessmen were ruined.[98]

#### Privateering

[edit]

The United Provinces issued a decree on 2 February 1826 authorizing privateers to attack Brazilian sea trade.[99]

### The war on land

[edit]

On land, the Argentine army initially crossed the Río de la Plata and established its headquarters near the town of Durazno. General Carlos María de Alvear invaded Brazilian territory and a series of skirmishes followed. Emperor Pedro I planned a counteroffensive by late 1826, and managed to gather a small army mainly composed of southern Brazilian volunteers and European mercenaries. The recruiting effort was hampered by local rebellions throughout Brazil, which forced the Emperor to relinquish direct command of his Army, return to Rio de Janeiro and bestow command of the troops on Felisberto Caldeira Brant, Marquis of Barbacena. The Brazilian counteroffensive was eventually stopped at the Battle of Ituzaingó.

The stalemate in the Cisplatine War was caused by the inability of the Argentine and Uruguayan land forces to capture major cities in Uruguay and Brazil,[100] the severe economic consequences imposed by the Brazilian blockade of Buenos Aires,[101] and the lack of manpower for a full-scale Brazilian land offensive against Argentine forces. There was also increasing public pressure in Brazil to end the war. All of this motivated the interest on both sides for a peaceful solution.

Given the high cost of the war for both sides and the threat it posed to trade between the United Provinces and the United Kingdom, the latter pressed the two belligerent parties to engage in peace negotiations in Rio de Janeiro. Under British mediation, the United Provinces and the Empire of Brazil signed the 1828 Treaty of Montevideo, which acknowledged the independence of Cisplatina under the name Eastern Republic of Uruguay.

The treaty also granted Brazil sovereignty over the eastern section of the former Eastern Jesuit Missions and, most importantly, guaranteed free navigation of the Río de la Plata, a central national security issue for the Brazilians.

## Aftermath

[edit]

In Brazil, the loss of Cisplatina added to growing discontent with Emperor Pedro I. Although it was far from the main reason, it was a factor that led to his abdication in 1831.

## Legacy

[edit]

Although the war was not a war of independence, as none of the belligerents fought to establish an independent nation, it has a similar recognition within Uruguay. The Thirty-Three Orientals are acknowledged as national heroes, who freed Uruguay from Brazilian rule. The landing of the Thirty-Three Orientals is also known as the "Liberation crusade".[102]

The war has a similar reception within Argentina, considered as a brave fight against an enemy of superior forces. The Argentine Navy has named many ships after people, events and ships involved in the war. William Brown (known as "Guillermo Brown" in Argentina) is considered the father of the Argentine navy,[103][104][105][106] and is treated akin to an epic hero for his actions in the war. He is also known as the "Nelson of the Río de la Plata".[107]

Brazil has had little interest in the war beyond naval warfare buffs. Few Brazilian historians have examined it in detail. The national heroes of Brazil are instead from Brazilian independence, the conflicts with Rosas (Platine War) or the Paraguayan War.[108]

Despite the role of Britain in the war, and the presence of British naval officials on both sides of the conflict, the war is largely unknown in the English-speaking world.[108]

1. ^ Articles I and II of the Preliminary Peace Convention, Câmara dos Deputados 1828, p. 121:
* Article I: "His Majesty, the Emperor of Brazil, declares the Province of Montevideo, today called Cisplatina, separated from the territory of the Empire of Brazil, so that it can constitute itself in a free State, and independent of all and any nation, under the form of government that it deems most suited to its interests, needs and resources."
* Article II: "The government of the Republic of the United Provinces of the Río de la Plata agrees to declare, for its part, the independence of the Province of Montevideo, today called Cisplatina, so that it constitutes a free and independent State in the terms declared in the preceding article."
2. ^ Portuguese: Guerra Cisplatina. Also known as the Argentine-Brazilian War (Spanish: Guerra argentino-brasileña) or, in Argentine and Uruguayan historiography, as the Brazil War (Spanish: Guerra del Brasil), the War against the Empire of Brazil (Spanish: Guerra contra el Imperio del Brasil), or the Liberating Crusade (Spanish: Cruzada Libertadora) in Uruguay.
3. ^ According to Doratioto 2009, pp. 219–220, the invasion "was not opposed by Buenos Aires, because, although [it] meant a loss of territory that would potentially be subordinate to them, on the other hand it contributed to strengthening the power of the Buenos Aires authorities to the extent that it put an end to the Artiguist project, an alternative to centralization".
4. ^ According to Rio Branco 2012, pp. 93–94, upon being incorporated, Cisplatina's limits with neighboring Rio Grande do Sul were set as the Quaraí and Chuí rivers.
5. ^ Lecor voted in favor of Brazil; in his justification, Álvaro da Costa declared that "[c]onquered by Portuguese weapons, this province shall not detach itself from the Portuguese cause to follow the fate of Brazil", Carneiro 1946, p. 34\. Apart from Cisplatina, in the south, the northern provinces of Grão-Pará, Maranhão, Piauí, Ceará and part of Bahia also remained loyal to Portugal, having to be militarily subjugated in the Brazilian War of Independence that followed through, Fundação Alexandre de Gusmão 2022, pp. 33–34.
6. ^ According to Pedro Calmon, the province had sent two deputies to the 1823 Constituent Assembly that was tasked with drafting Brazil's first constitution, Calmon 2002, p. 192\. The constitution drafted by the Assembly was rejected by emperor Pedro I, who dissolved the Assembly and issued a constitution himself in 1824, Lustosa 2007, pp. 135–136. Under his Constitution, Cisplatina enjoyed a considerable degree of autonomy, more so than other provinces within the Empire, Manning 1918, p. 295.
7. ^ Their goals varied, some wanted to join the United Provinces while others simply wanted independence, Carneiro 1946, p. 37.
8. ^ Notably Juan Antonio Lavalleja, who would later lead the insurgents against Brazil. Lavalleja had fought against the Luso-Brazilian invasion, but was captured in 1818 and imprisoned for three years at Ilha das Cobras, Rio de Janeiro, being released in 1821, Carneiro 1946, pp. 38–39.
9. ^ Rivera published a manifesto, dated 13 February 1825, in which he declared he would defend Cisplatina's incorporation into Brazil "with the good faith incumbent on a man of honour, and a soldier". According to Armitage, the message was insincere, but still managed to "remove the suspicions of the Court of Rio", Armitage 1836, p. 215.
10. ^ According to Carneiro 1946, pp. 38–39, they were: Manuel Oribe, Pablo Zufriátegui [es], Simon del Pino, Manuel Lavalleja [es], Manuel Freire, Jacinto Trapani, Gregorio Sanabria, Manuel Meléndez, Atanasio Sierra, Santiago Gadea [es], Pantaleón Artigas, Andres Spikerman, Juan Spikerman [es], Celedonio Rojas, Andres Cheveste, Juan Ortiz, Ramón Ortiz, Avelino Miranda, Carmelo Colman, Santiago Nievas, Miguel Martínez, Juan Rosas [es], Tiburcio Gómez [es], Ignacio Núñez, Juan Acosta [es], José Leguizamon, Francisco Romero, Juan Arteaga, Dionisio Oribe and Juaquim Artigas, including Juan Antonio Lavalleja and two rowers. Out of the 33, 16 were foreigners: 11 Argentines, 1 French, 1 Brazilian, 1 Paraguayan and 2 Africans.
11. ^ Rivera's action was qualified by Brazilian historian David Carneiro as a betrayal of those who previously considered him a friend, Carneiro 1946, p. 41\. Uruguayan historian Washington Lockhart says, on the other hand, that the defection was not "spontaneous and unconditional", mentioning that, when captured by Lavalleja, Rivera begged for his life. Still according to Lockhart, Rivera's defection was "unworthily" called "the embrace of Monzon [es]" by politicized historians, Lockhart 1996, p. 22.
12. ^ It reads: Having the Government of the United Provinces of the River Plate practiced acts of hostility against this Empire without provocation, and without preceding an express declaration of war, disregarding the forms received among civilized nations, it suits the dignity of the Brazilian Nation and the order that it must occupy among the powers, that I, having heard my Council of State, declare as I do declare war against the said provinces and their government: therefore I order that all possible hostilities be carried out against them by sea and land, authorizing privateering and armament, which my subjects might want to propose themselves against that nation; Declaring that all takings and prizes, whatever their quality, will belong completely to their captors, without any deduction for the benefit of the Public Treasury. May the Supreme Military Council understand it as such and publishes it, sending it by copy to the competent stations and publishing it in notices.

Rio de Janeiro Palace on 10 December 1825, the fourth [year] of the independence and the Empire.

With his imperial majesty's signature. Viscount of Santo Amaro.
