Question

What was the most significant benefit to the Union of the siege at Vicksburg?

Answer 1

Lincoln was able to enforce the Emancipation Proclamation in parts of Mississippi.

Answer 2

As a result of the siege at Vicksburg, Texas, Arkansas and Louisiana were isolated from the rest of the Confederation and the loss also meant for the Confederation the loss of livestock and agricultural resources of the first two. Additionally, the victory in Vicksburg and the victory in Gettysburg the previous day marked the beginning of the end of the Civil War, while Grant with his victory increased his fame, which later made him commander in chief of the Union troops during that contest.
