The Battle of Fallen Timbers (August 20, 1794) was the final battle of the Northwest Indian War, a struggle between Native American tribes affiliated with the Western Confederacy, including minor support from the British, against the United States for control of the Northwest Territory (an area north of the Ohio River, east of the Mississippi River, and southwest of the Great Lakes). The battle, which was a decisive victory for the United States, ended major hostilities in the region until Tecumseh's War and the Battle of Tippecanoe in 1811.
