Significance

  • Lieutenant General John C. Pemberton’s surrender of the Army of the Mississippi marked the second time that an entire Confederate army surrendered to Ulysses S. Grant, the first being at Fort Donelson.
  • During the Siege of Vicksburg, inhabitants of the city dug over 500 caves that they inhabited to escape injury from Union bombardment.
  • Vicksburg’s fall gave the Union complete control of the Mississippi River, reestablishing trade through the Gulf of Mexico.
  • Vicksburg’s fall severed the Confederacy’s connections with territories in the American West, denying the South essential agricultural supplies.
  • The success of the Vicksburg Campaign also restored Ulysses S. Grant’s reputation, which had suffered after the surprise attack at Shiloh. The renewed confidence in Grant would have a decisive impact on later events in the eastern theater and on the conclusion of the war.
  • The Siege of Vicksburg ended one day after the Union victory at the Battle of Gettysburg.
