Battle of the Wabash
The Battle of the Wabash, also known as St. Clair's Defeat, was fought on this day in the Northwest Territory between the United States and the Western Confederacy of American Indians, as part of the Northwest Indian War. It was one of the worst defeats, in percentage of casualties, suffered by the United States Army. It was also the largest victory ever won by American Indians.

The American Indians were led by Little Turtle of the Miamis, Blue Jacket of the Shawnees and Buckongahelas of the Delawares (Lenape). The war party numbered more than one thousand warriors, including a large number of Potawatomis from eastern Michigan and the Saint Joseph. The opposing force of about 1,000 Americans was led by General Arthur St. Clair. The forces of the American Indian confederacy attacked at dawn, taking St. Clair's men by surprise. Of the 1,000 officers and men that St. Clair led into battle, only 24 escaped unharmed. As a result, President George Washington forced St. Clair to resign his post and Congress initiated its first investigation of the executive branch.
