What type of war did Sherman declare on the south?

General William Tecumseh Sherman declared a type of warfare known as "total war" on the South during the American Civil War. This strategy aimed to undermine the Confederate war effort by targeting not only military forces but also civilian infrastructure, resources, and morale. His infamous "March to the Sea" from Atlanta to Savannah exemplified this approach, as it involved widespread destruction of railroads, crops, and towns to cripple the Southern economy and resolve. Sherman's tactics significantly contributed to hastening the end of the war.
