Tecumseh was a Native American leader of the Shawnee and a large tribal confederacy, known as Tecumseh's Confederacy, which opposed the United States during Tecumseh's War and became an ally of Britain in the War of 1812.During the War of 1812, Tecumseh's confederacy allied with the British and helped in the capture of Fort Detroit. He helped British Major-General Sir Isaac Brock’s men to force the city to surrender in August 1812 As Brock advanced, Tecumseh had his four hundred warriors parade out from a nearby forest and circle back around to repeat the parade, making it appear that there were many more warriors under his command than there were. Brigadier General William Hull, the fort commander, surrendered in fear of a massacre. The victory was of a great strategic value to the British allies.The victory at Detroit was reversed a little over a year later. Commodore Perry's victory on Lake Erie late in the summer of 1813 cut the British supply lines. The British found themselves in an indefensible position and had to withdraw from Detroit. They burned all public buildings in Detroit and retreated into Upper Canada along the Thames Valley. Tecumseh still wanted British support in order to defend tribal lands against the Americans. American forces caught him and his warriors at the Battle of the Thames, and killed Tecumseh on October 5, 1813. With his death, Tecumseh’s confederation fell apart. Tecumseh became an iconic folk hero in American, Aboriginal and Canadian history.
