William T. Sherman pillages his way through Georgia to destroy the South.
General William Tecumseh Sherman burns his way through Georgia, leaving a 20-mile wide trail of destruction behind. He wanted to bring hell unto the South, and he sure did.
Sherman's act is ethically disgusting to many, but was also tactically quite significant. His "scorched-earth" method destroyed Southern supplies and morale just as much as it demonstrated the horrors of war, so it certainly worked.
"War is cruelty, and you cannot refine it; and those who brought war into our country deserve all the curses and maledictions a people can pour out."
