What did William Tecumseh sherman want to show the southerners that their government could not do?

William Tecumseh Sherman sought to demonstrate to the Southerners that their government could not protect them from the consequences of war and its devastation. Through his infamous "March to the Sea," Sherman aimed to undermine the Confederacy's will to fight by destroying military targets, infrastructure, and civilian property. This strategy was intended to illustrate the futility of their cause and to accelerate the South's surrender by showcasing the Union's overwhelming power. Ultimately, he wanted to convey that the Confederate government was incapable of safeguarding its citizens against the Union's might.
