Final answer:
The Anaconda Plan aimed to divide the Confederacy and disrupt its supply lines. Control of the Mississippi River would further isolate Confederate states, and the North's industrial capacity granted it a military advantage. The Mississippi River's significance lay in its function as a vital Southern transportation route.
Step-by-step explanation:
The goal of the Anaconda Plan was to split the South in two and cut off the South's supply routes. By gaining control of the Mississippi River, the North could isolate three Confederate states, creating strategic disadvantages for the Confederacy. The number of factories in the North provided a significant military advantage during the Civil War, as these industries supported the Union's war effort by producing essential supplies and materials. The North also recognized the importance of the Mississippi River because it was the South's major transportation link, essential for moving troops, supplies, and trade goods.
