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

The Mississippi river was key to connecting Union forces in the north, to forces in the south.

Union army could use the Mississippi River for the transport of its troops into Confederate territory.

Confederacy could no longer use the Mississippi River to carry its goods to sea or use it to supply troops

Confederacy would not be able to split Union forces if they lost control of the river.

Additionally, the Mississippi River was also an important transportation route for the shipment of goods and supplies from the Midwest to the eastern states. By controlling the river, the Union could cut off the Confederacy's supply lines and weaken their military and economic power. The capture of key cities along the river, such as New Orleans and Vicksburg, were crucial victories for the Union in securing control of the Mississippi River.
