11. Why was control of the Mississippi River an important goal of the Union strategy in the West?

The Union army could use the Mississippi for training purposes.
The Mississippi River was key to connecting railroad system in the west to the industrial South.
The Confederacy would not be able to split Union forces if they lost control of the river.
Confederacy could no longer use the Mississippi River to carry its goods to sea or use it to supply troops

. The Confederacy relied heavily on the Mississippi River for transportation and supplies, so controlling it would disrupt their ability to move troops and materials effectively. Additionally, cutting off Confederate access to the river would prevent them from using it to export goods and receive imports, weakening their economy and overall war effort. By controlling the Mississippi River, the Union could effectively block Confederate efforts in the west and maintain control over key logistical and strategic routes.

What answer?

The answer is that the Confederacy could no longer use the Mississippi River to carry its goods to sea or use it to supply troops.
