Was Sherman's Total War effort Necessary or Unnecessary to win the Civil War for the North?
Necessary
Unnecessary

Yes, Sherman's Total War strategy was necessary to avoid a stagnation in the strategic development of the war. Otherwise, the conflict between North and South could have taken much longer to resolve.

Explanation:

Sherman's Total War effort was carried out during his March to the Sea, carried out from November 15 to December 22, 1864.

Northern General William T. Sherman launched a march from Atlanta, Georgia, to Savannah on the Atlantic coast, using the tactics of total war. He destroyed infrastructure such as roads and railways, killed livestock and burned houses so that the enemy could not gain reinforcement or food. Through the march, large parts of the southern states' physical and psychological ability to wage war were destroyed. The morale of the southern army was destroyed and mass deserts followed.
