Secretary of War Henry Knox ordered Brigadier General Josiah Harmar to launch a major offensive against the Shawnee and Miami Natives living in the region. In October 1790, his force of 1,453 men was assembled near present-day Fort Wayne, Indiana. At least 129 soldiers were killed. Determined to avenge the defeat, the president ordered Major General Arthur St. Clair, who was serving as the governor of the Northwest Territory, to mount a more vigorous effort by the third quarter of 1791. After considerable trouble finding men and supplies, St. Clair was finally ready. At dawn on November 4, 1791, his poorly trained force, accompanied by about 200 camp followers, was camped near the present-day location of Fort Recovery, Ohio. Wayne's soldiers advanced toward Fort Miami and on August 20, 1794, encountered Native American confederacy forces led by Blue Jacket, in what has become known as the Battle of Fallen Timbers.
