What geography advantage did the union army have during the siege of Vicksburg?

Answer 1

During the Battle of Vicksburg (meaning the engagements before the siege), the Confederate commander, Pemberton, was receiving conflicting orders from his immediate chief Joseph Johnston and his president Jefferson Davis. This put him in a vulnerable position, which Grant was able to exploit.

Apart from that, there was the simple matter of Generalship. Grant was simply a better strategist and tactician than the inexperienced Pemberton.

Answer 2

It enabled them to liberate the Mississippi, denying the Confederates all use of this important military highway, and isolating all enemy units West of the river.

Grant was then free to go to the aid of the Army of the Cumberland at Chattanooga, saving it from starvation, and making possible the advance on Atlanta.

Answer 3

The Union army had the geographic advantage of controlling much of the Mississippi River. Grant and Sherman were able to place pressure on Vicksburg with a combination of land and river dominance.

Answer 4

The Union won the Battle of Vicksburg by laying siege to the city. This caused the Confederate forces to stay split instead of uniting.

Answer 5

More Industrial and had a (not so well trained) army and navy.

Answer 6

The Union outnumbered the Confederacy significantly in weapons because they were vastly more industrialized.
