On 30 June 1794, just outside the gates of Fort Recovery, built on St. Clair's battlefield, a pack-horse convoy, led by Major William Friend McMahon, was attacked by 2,000 Native Americans. After Major McMahon was killed and the rest of the survivors fled to the protection within the fort, a full-scale attack was made on the fortification. Many of the approximately 125 soldiers defending the fort were expert riflemen, and Fort Recovery also had artillery. The battle lasted two days, but the Legion maintained control of the fort. Some scholars believe there were more native warriors involved in the attack of Fort Recovery than at the climactic Battle of Fallen Timbers.
