In 1794, nineteen-year-old Tenskwatawa was present at the Battle of Fallen Timbers with two of his brothers, Tecumseh and Sauwauseekau, but he did not distinguish himself as a warrior. Instead, Tenskwatawa viewed the battle as a chance to re-insert himself into tribal society. In his late twenties, he decided to become a medicine man and apprenticed with a tribal healer, Penagashea ("Changing Feathers"). However, when Tenskawatawa was unable to save his people after they fell seriously ill, probably with influenza, he became humiliated and even more depressed. By the early 1800s, Tenskawatawa had developed a reputation as a notorious drunk among the Shawnee living along the White River.
