Organizer of Indian confederation - Tecumseh
In 1811, while Tecumseh was in the South, William Henry Harrison, governor of the Indiana Territory, marched up the Wabash River and camped near the brothers’ settlement. The Prophet unwisely attacked Harrison’s camp and was so decisively defeated in the ensuing Battle of Tippecanoe that his followers dispersed, and he, having lost his prestige, fled to Canada and ceased to be a factor in Tecumseh’s plans.
Seeing the approach of war (the War of 1812) between the Americans and British, Tecumseh assembled his followers and joined the British forces at Fort Malden on the Canadian side of the Detroit River. There he brought together perhaps the most formidable force ever commanded by a North American Indian, an accomplishment that was a decisive factor in the capture of Detroit and of 2,500 U.S. soldiers (1812).
