inherited their father's money, so he lacked the funds for his further medical schooling, which he had also discovered he didn't prefer. He therefore withdrew from medical school, though school archives record him as a "non-graduate alumnus of Penn's medical school class of 1793". With the influence of his father's friend, Governor Henry Lee III, he embarked upon a military career. Early military career On August 16, 1791, within 24 hours of meeting Lee, Harrison, age 18, was commissioned as an ensign in the Army and assigned to the First American Regiment. He was initially assigned to Fort Washington, Cincinnati in the Northwest Territory where the army was engaged in the ongoing Northwest Indian War. Biographer William W. Freehling says that young Harrison, in his first military act, rounded up about eighty thrill-seekers and troublemakers off Philadelphia's streets, talked them into signing enlistment papers, and marched them to Fort Washington. Harrison was promoted to lieutenant after Major General "Mad Anthony" Wayne took command of the western army in 1792, following a disastrous defeat under Arthur St. Clair. In 1793, he became Wayne's aide-de-camp and acquired the skills to command an army on the frontier; he participated in Wayne's decisive victory at the Battle of Fallen Timbers on August 20, 1794, which ended the Northwest Indian War. He received the following commendation from Wayne for his role in the battle: "I must add the name of my faithful and gallant Aide-de-camp ... Lieutenant Harrison, who ... rendered the most essential service by communicating my orders in every direction ... conduct and bravery exciting the troops to press for victory." Harrison was a signatory of the Treaty of Greenville (1795), as witness to Wayne, the principal negotiator for the U.S. Under the terms of the treaty, a coalition of Indians ceded a portion of their lands to the federal government, opening two-thirds of Ohio to settlement. At his mother's death in 1793, Harrison inherited a portion of his family's Virginia estate, including approximately of land and several slaves.
