On November 3, 1791, the army of a confederation of Indian tribes, led by Blue Jacket and Miami Chief Little Turtle, defeated an American expedition led by Arthur St. Clair, governor of the Northwest Territory. The engagement, known as the Battle of the Wabash or St. Clair's Defeat, was the crowning achievement of Blue Jacket's military career, and the most severe defeat ever inflicted upon the United States by Native Americans. Traditional accounts of the battle tend to give most of the credit for the victory to Little Turtle. John Sugden argues that Little Turtle's prominence is due in large measure to Little Turtle's self-promotion in later years.
