Tippecanoe (tĭpˌəkənōˈ) [key], river, c.170 mi (270 km) long, rising in the lake district of NE Ind. and flowing SW to the Wabash River, near Lafayette. U.S. Gen. William Henry Harrison fought the Shawnees in the battle of Tippecanoe, Nov. 7, 1811, on the site of Battle Ground, Ind. The Native Americans, encouraged by their chief, Tecumseh, and by the British, became threatened by the continued U.S. advance into their territory. At the time of Harrison's expedition, Tecumseh was away and his brother, the Shawnee Prophet, led the group. They attacked U.S. forces at dawn but were repelled; their village was subsequently razed by Harrison's forces. Claimed as a U.S. victory, the battle was at best indecisive; the power of the Shawnees was broken, however, despite the subsequent American retreat.
