Siege of Vicksburg

The Battle of Vicksburg, or Siege of Vicksburg, was the final significant battle in the Vicksburg Campaign of the American Civil War. In a series of skilled maneuvers, Union  Maj. Gen. Ulysses S. Grant and his Army of the Tennessee crossed the Mississippi River and drove the Confederate army of  Lt. Gen. John C. Pemberton into defensive lines surrounding the fortress city of Vicksburg, Mississippi. Grant besieged the city from May 18 to July 4, 1863, until it surrendered, yielding command of the Mississippi River to the Union.
