The new command was trained at Legionville, near present-day Baden, Pennsylvania. The base was the first formal basic training facility for the United States military. Throughout the winter of 1792-93, existing troops along with new recruits were drilled in military skills, tactics and discipline. The Legion then went on to fight the Northwest Indian War, a struggle between American Indian tribes affiliated with the Western Confederacy in the area south of the Ohio River. The overwhelmingly successful campaign was concluded with the decisive victory at the Battle of Fallen Timbers on August 20, 1794. The training the Legion received at Legionville was seen as instrumental to this victory.
