On the morning of 20 August, the Legion broke camp and marched toward the Maumee River near modern Toledo, Ohio, where an ambush had been set by the Confederacy. This late in the campaign, the Legion was reduced to about 3,000 soldiers and militia, with many soldiers defending the supply trains and forts. Blue Jacket, the Native alliance commander, had selected a battlefield where a tornado had felled hundreds of trees, creating a natural defensive barrier. Here, he placed confederation forces of about 1,500 warriors: Blue Jacket's Shawnees, Delawares led by Buckongahelas, Miamis led by Little Turtle, Wyandots led by Tarhe and Roundhead, Mingos, a small detachment of Mohawks, and a British company of Canadian militiamen dressed as Native Americans under LTC William Caldwell.
