Union forces from Brazos Island launched the Brazos Santiago Expedition, leading to the last battle of the Civil War, the Battle of Palmito Ranch, fought in Texas form May 12 to 13th, 1865, well after Robert Edward Lee’s surrender on April 9, 1865, at Old Appomattox Court House, Virginia.
The Battle of Palmito Ranch was a victory for the confederate army. However, due to the surrender of the armies of the remainder of the confederacy, the victory did not change the outcome of the war.
The site of the last Civil War battle has been designated as the the Palmito Ranch Battlefield National Historic Landmark.
