## History

[edit]

On April 29, 1865, rebel sympathizers in the town started "rejoicing over the death of President Lincoln." When news reached Benicia a company of militia was sent to stop these acts of celebration. When the militia met the "party" of secessionists gunfire was exchanged and 2 members of the militia were wounded. After several shots the sympathizers surrendered to the militia ending the short battle.[6]
