Unaware of Lee's surrender to Grant and the assassination of Abraham Lincoln, Union and Confederates clashed in the Battle of Columbus, Georgia, on Easter Sunday, April 16, 1865, when a Union detachment of two cavalry divisions under Maj. Gen. James H. Wilson attacked the lightly defended city and burned many of the industrial buildings. John Stith Pemberton, who later developed Coca-Cola in Columbus, was wounded in this battle. Col. Charles Augustus Lafayette Lamar, owner of the last slave ship in America, was also killed here. A historic marker erected in Columbus notes that this was the site of the "Last Land Battle in the War from 1861 to 1865."
