The famous general known for his "March to the Sea" during the American Civil War is William Tecumseh Sherman. In late 1864, Sherman led Union forces from Atlanta to Savannah, Georgia, in a military campaign aimed at crippling the Confederate war effort. His strategy involved total warfare, targeting not only enemy troops but also the infrastructure and resources supporting the Confederacy, including railroads and supplies. Sherman's approach aimed to demoralize the Southern population and hasten the end of the war. His tactics, while controversial, contributed significantly to the Union's success, ultimately leading to the Confederacy's defeat.
