What was the purpose of the union march on Atlanta?

The Union march on Atlanta, led by General William Tecumseh Sherman during the American Civil War, aimed to demonstrate military might and disrupt Confederate infrastructure and morale. It was part of Sherman’s broader strategy of "total war," intended to weaken the South's ability to sustain the war effort. The march also sought to bolster Northern resolve by showcasing the Union's commitment to victory. Ultimately, the capture of Atlanta in September 1864 became a significant turning point in the war and boosted President Lincoln's re-election campaign.
