The Battle of Raymond was fought on May 12, 1863, near Raymond, Mississippi, during the Vicksburg Campaign of the American Civil War. The bitter fight pitted elements of Union Army Maj. Gen. Ulysses S. Grant's Army of the Tennessee against Confederate forces of Lt. Gen. John C. Pemberton's Department of the Mississippi and East Louisiana. The Confederates failed to prevent the Federal troops from reaching the Southern Railroad and isolating Vicksburg, Mississippi, from reinforcement and resupply.
