St. Clair's Defeat was the worst defeat of an American army by Native Americans in U.S. history. This ended with the Battle of Fallen Timbers and Treaty of Greenville. Those Miami who still resented the United States gathered around Ouiatenon and Prophetstown, where Shawnee Chief Tecumseh led a coalition of Native American nations.
