Vicksburg Campaign - Grants Advance from Jackson to Vicksburg and the Battle of Chapman's Hill

1863-05-15/1863-05-19

The Vicksburg campaign was a series of maneuvers and battles in the Western Theater of the American Civil War directed against Vicksburg, Mississippi, a fortress city that dominated the last Confederate-controlled section of the Mississippi River. The Union Army of the Tennessee under Major General Ulysses S. Grant gained control of the river by capturing this stronghold and defeating Lieutenant General John C. Pemberton's forces stationed there. The campaign consisted of many important naval operations, troop maneuvers, failed initiatives, and eleven distinct battles from December 26, 1862, to July 4, 1863. Military historians divide the campaign into two formal phases: operations against Vicksburg (December 1862 – January 1863) and Grant's operations against Vicksburg (March–July 1863).
