In May 1782, Colonel William Crawford led over 450 volunteers across Ohio to attack British-allied Native Americans who had been raiding the frontiers of Pennsylvania and Virginia for years. An experienced yet reluctant commander, Crawford and his men clashed with a similarly sized force of British Rangers and Wyandot, Delaware, and Shawnee Indians on the Sandusky River in early June. After three days, the Americans were routed in one of the worst defeats American arms suffered on the frontier during the American Revolution. During the retreat, Native American warriors captured dozens of men, including Colonel Crawford. Many were horrifically tortured to death in revenge for the Gnadenhutten massacre earlier that spring, when American volunteers bludgeoned nearly one hundred unarmed and unresisting Delaware Indians to death.
