The Harmar campaign was an attempt by the United States Army to subdue confederated Native Americans nations in the Northwest Territory that were seen as hostile in Autumn 1790. The campaign was led by General Josiah Harmar and is considered a significant campaign of the Northwest Indian War. The campaign ended with a series of battles on 19–21 October 1790 near the Miami villages of Kekionga. These were all overwhelming victories for the Native Americans and are sometimes collectively referred to as Harmar's Defeat.
