1811: Tecumseh and his American Indian Confederacy defeat William Henry Harrison in the Battle of Tippecanoe. Tecumseh and his men continue on and defeat the Americans at Fort Mackinac. These two defeats convince the United States that Great Britain was aiding the Indians in their conquests. Much of America now wants war with Britain. The Indians then burned the city of Brownstown, despite being outnumbered 5 to 1 by the Americans.
