St. Clair's defeat was a battle fought between the United States and the Western Confederacy of Native Americans on November 4, 1791, during the Northwest Indian War. Out of a US force of roughly 1000 men and officers, only 24 escaped unharmed. It has been cited as the most decisive defeat in the history of the American military and its largest defeat ever by Native Americans. This pamphlet is a compilation of three articles published in 1847, 1851 and 1864.
