Final answer:
The Northern strategy, known as the Anaconda Plan, involved a blockade to weaken the South. The Southern strategy, attrition, aimed to wear down the Northern army. The North's strategy eventually proved more successful due to greater resources and industrial capacity.
Step-by-step explanation:
The Northern strategy for winning the American Civil War was known as the Anaconda Plan. It involved a blockade of the Southern ports, cutting off the Confederacy's access to supplies and foreign aid. This strategy aimed to slowly suffocate and weaken the South, like the grip of an anaconda, and ultimately lead to its defeat.
On the other hand, the Southern strategy, also known as attrition, focused on wearing down the Northern army and exploiting its disadvantages. The Confederacy aimed to prolong the war, inflict heavy casualties on the Union, and make the conflict too costly for the North to continue.
The North's Anaconda Plan proved to be more successful in the long run, as the Union gradually gained control of the Southern ports and weakened the Confederate economy. Additionally, the Union had greater resources and industrial capacity, which allowed them to sustain a prolonged war effort.
