What was the last Confederate victory in the Civil War?
Battle of Palmito Ranch
The Battle of Palmito Ranch 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. Since the Confederacy had ceased to exist, it is also argued that this battle should be classified as a postwar action.
Danville Leadbetter
Leadbetter's last Confederate command was the District of the Gulf (Department of Alabama, Mississippi, & East Louisiana) from November 22 to December 12, 1864. There is no record of him receiving a parole from the U.S. Government when the Civil War ended.
