Explanation:
During the Civil War, the Unions plan focused on cutting off resources of the Confederacy. The Union planned to put a blockade in all Southern coasts to eliminate the help from foreign countries. This blocking strategy came to be known as the Anaconda Plan. The Union also wanted to control over the Mississippi River. The river played a significant role for the South because it was the last port on the river held by them. Confederate troops provided goods and ammunition to Louisiana, Texas, and Arkansas.
