Grant hoped to secure control of the Mississippi River for the Union. By having control of the river, Union forces would split the Confederacy in two and control an important route to move men and supplies. The last major Confederate stronghold on the Mississippi River was the city of Vicksburg, Mississippi.
The siege of Vicksburg (May 18 – July 4, 1863) was the final major military action in the Vicksburg campaign of the American Civil War. In a series of maneuvers, Union Maj. Gen. Ulysses S. Grant and his Army of Tennessee crossed the Mississippi River and drove the Confederate Army of Mississippi, led by Lt., Gen. John C. Pemberton, into the defensive lines surrounding the fortress city of Vicksburg, Mississippi.
