William Tecumseh Sherman (February 8, 1820 — February 14, 1891) was an American general who served the United States during the American Civil War. He is most famous for creating the modern ideal of "Total War" and his infamous March to the sea.
In pop culture, he is a man who brings about a lot of mixed feelings. To many in the South, he is seen as a monster who destroyed while his men raped, looted and pillaged Georgia and South and North Carolina. To others, particularly in the North, he was a brilliant man who helped end the civil war quicker and ensured the Union's survival and slavery's end, along with General Grant and Abraham Lincoln.
Trope Namer for War Is Hell, from a speech that Sherman, disdainful of military glory, gave at a military academy's graduation ceremony. (On another occasion he also said "War is cruelty, and you cannot refine it.")
