The Importance of St. Clair’s Defeat

In the fall of 1791, an ill-trained and poorly supplied American army led by General Arthur St. Clair was annihilated by a confederation of Native American forces in the Ohio wilderness. This engagement remains the most catastrophic defeat the U.S. military has ever suffered at the hands of Native Americans. The American failure stemmed from presumptions of superiority and a blatant disregard for basic security, while the Native force executed a coherent plan with superior intelligence and unified command. The battle was a pivotal moment in the broader Northwest Indian War, a conflict fueled by the new nation's relentless westward expansion into Native lands.
