The correct answer is C) the destruction of Georgia would be so complete that it would break the Confederacy's will to continue fighting.
The BEST reasoning behind William T. Sherman's strategy of using "total war " to defeat the south was "the destruction of Georgia would be so complete that it would break the Confederacy's will to continue fighting."
That was his goal with the Total War. The Union had to win the war at any cost, so he decided to led his troops in November 1864 from Atlanta to Savanah, Georgia. It was an army of approximately 60,000 soldiers. Sherman wanted to create fear in the people of Georgia, so he and his men steal food and burned crops to force the people to stop supporting the Confederates. With this total war concept, Georgia was completely destroyed and indeed the people from the state were afraid.
The other options of the question were A) the strategy of "total war " was needed to stop the confederates from trading with France and England. B) Sherman's men wanted revenge from the horrifying treatment of Union soldiers in Andersonville prison camp. D) the invasion of Georgia would lead to an armed revolt by the slaves, which in turn would help the Union to win the war.
