The most gruesome crime in history is thought to be the Purge of Pengcheng, believed to have occurred in 1477 B.C. In this attack, an invading Mongol army is said to have slaughtered up to half a million people in the city of Pengcheng. Victims were thrown into the surrounding sea to prevent them from becoming food for the fish, and even babies were killed.
