The town of Grand Gulf was burned by Admiral David Farragut's men in 1862 and occupied by Porter's Mississippi Squadron on May 3, 1863. The Union occupation followed Confederate Brig. Gen. John Bowen's evacuation of the town after the Battle of Port Gibson on May 1. Gen. U.S. Grant visited here on May 3, and established Grand Gulf as the primary Union supply depot for the duration of the Vicksburg Campaign. From Grand Gulf, some 200 wagons per day were used to resupply Grant's army.
