August 20, 1794: The final battle between Native Americans and the United States for the control over the Northwest Territory took place on this date. The Battle of Fallen Timbers, located in northwestern Ohio, involved many Indian tribes, including the Ojibwas and Potawatomis. The battle resulted in a decisive victory for the army, led by General "Mad" Anthony Wayne, and proved to be a turning point in the development of the Northwest Territory, the region that would eventually become the states of Ohio, Michigan, Indiana, Illinois and Wisconsin. The outcome of the battle was a deciding factor for the British, who had supported the Indian coalition, to evacuate their posts in the region. With the British now gone from the area and with subsequent treaties with the Native Americans, the path was clear for American settlement in the Northwest Territory.
