Answer:
The Siege of Vicksburg (May 18, 1863-July 4, 1863) was a decisive Union victory during the American Civil War (1861-65) that divided the confederacy and cemented the reputation of Union General Ulysses S. Grant (1822-85). Union forces waged a campaign to take the Confederate stronghold of Vicksburg, Mississippi, which lay on the east bank of the Mississippi River, halfway between Memphis to the north and New Orleans to the south. The 47-day siege gave control of the Mississippi River to the Union, a critical supply line, and was part of the Union’s Anaconda Plan to cut off outside trade to the Confederacy.
