Tecumseh.
The Battle of Bloody Creek was an 1811 battle of Tecumseh's War between the Indian Army of the Shawnee war chief Tecumseh and the Indiana militia. Sobel does not say where in the Confederation of Indiana the Battle of Bloody Creek took place, but he does state that Tecumseh's army wiped out the Indianan army. With Indiana's military forces destroyed, Tecumseh was able to range through the confederation at will, attacking white settlements. By the summer of 1814 Tecumseh was able to launch the Siege of Burgoyne, threatening to destroy the capital city of the Confederation of North America.
Sobel's sources for the Battle of Bloody Creek are William Henry Harrison's memoirs, The Autobiography of William Henry Harrison (Burgoyne, 1840); and Henry Brand's Tecumseh and the Indianan Wars (New York, 1970).
