The Battle of Palmito Ranch, also known as the Battle of Palmito Hill, is considered by some criteria as the final battle of the American Civil War. It was fought May 12 and 13, 1865, on the banks of the Rio Grande east of Brownsville, Texas, and a few miles from the seaport of Los Brazos de Santiago, at the southern tip of Texas. The battle took place more than a month after the general surrender of Confederate forces to Union forces at Appomattox Court House, which had since been communicated to both commanders at Palmito, and in the intervening weeks the Confederacy had collapsed entirely, so it could also be classified as a postwar action.
