The United States military realized it needed a well-trained
standing army following
St. Clair's Defeat on November 4, 1791, when a force led by
General Arthur St. Clair was almost entirely wiped out by the
Northwestern Confederacy near modern
Fort Recovery, Ohio. The plans, which were supported by U.S. President
George Washington and
Henry Knox,
Secretary of War, would lead to the creation of the
Legion of the United States. The command would be based on the 18th-century military works of
Henry Bouquet, a professional Swiss soldier who served as a
colonel in the
British Army, and French
Marshal Maurice de Saxe. In 1792
Anthony Wayne, a renowned hero of the
American Revolutionary War, was encouraged to leave retirement and return to active service as Commander-in-Chief of the Legion with the rank of
major general. The Legion, which was recruited and raised in
Pittsburgh, Pennsylvania, was formed around elements of the
1st and 2nd Regiments from St. Clair's army that had fought at the Battle of the Wabash. These units then became the
First and
Second Sub-Legions. The Third and
Fourth Sub-Legions were raised from additional recruits. From June 1792 to November 1792, the Legion remained cantoned at
Fort LaFayette in Pittsburgh. 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. However, after Wayne's death,
Brigadier General James Wilkinson, who was once Wayne's second-in-command of the Legion, began disbanding his former superior's organization in December 1796. His policy was to re-establish a military model based on a regimental system. Wilkinson, who was later found to be a
paid agent for the
Spanish Crown, tried to rid the US Army of everything Wayne had created. This resulted in the 1st, 2nd, 3rd and 4th Sub-Legions becoming the 1st, 2nd, 3rd and 4th Regiments of the United States Army. Nevertheless, the new regiments honored their foundations: • Part of the shield in the coat-of-arms of the
1st US Infantry Regiment is red in honor of the 2nd Sub-Legion. • The
Distinctive Unit Insignia worn on the uniform
epaulette and
beret by the
3rd US Infantry (The Old Guard) show a golden cocked hat with plume. This insignia represents the crest of the Old Guard's
coat of arms which shows a black cocked hat with white, which were the colors of the 1st Sub-Legion. • The coat-of-arms of the
4th US Infantry Regiment is green and white in honor of the 4th Sub-Legion. In 1808, Congress agreed to the expansion of the Regular Army as a result of deteriorating American relations with Britain. This led to the establishment of the 5th, 6th and 7th Regular infantry regiments, and a
Regiment of Riflemen. ==War of 1812==
