Union morale was low after its many losses, and victories would raise that morale.
Explanation:
The Western Theatre of the Civil War refers to the military operations that took place in the states of Alabama, Georgia, Florida, Mississippi, North Carolina, Kentucky, South Carolina and Tennessee. The Western Theatre allowed Union troops to have direct access to the most productive regions of the South, which were also harder for the Confederacy to defend, as they were far from the most populated areas. This advantage allowed the Union to enjoy a series of important victories, which raised morale among the troops.
