Near present-day Baden, Pennsylvania, Legionville was established in the winter of 1792 under Major General Anthony Wayne as the first formal basic training facility of the United States military. Created after St. Clair’s Defeat exposed the need for a better-trained standing army, the camp became a large, fortified cantonment where troops drilled intensively in marksmanship, bayonet use, field maneuvers, and discipline. Peace talks with Seneca leaders failed there in 1793 before the Legion departed for the Northwest Indian War. The training at Legionville was widely credited with preparing the army for victory at Fallen Timbers and the Treaty of Greenville, securing the site’s lasting military and archaeological importance.
