The Legion conducted a movement to contact and found an established ambush in a field of trees that had blown over in a storm (the "fallen timbers"). The Legion's front withdrew when it was attacked, but the troops closed quickly and pressed with the bayonet. The Native forces could not rally an attack, and withdrew to the nearby British-controlled Fort Miami. Unwilling to initiate a military battle with the United States, the commander of the fort refused to open the gates, forcing the Native American forces to withdraw from the area. Although the battle lasted little more than an hour, Fallen Timbers was the culmination of an arduous campaign and owed its success to the intense training and discipline of the Legion of the United States. The Legion encamped in the vicinity of Fort Miami for 3 days, but without their heavy artillery, they finally withdrew.
