The 1st Infantry saw its first combat in an unsuccessful campaign against the Miami tribe near modern-day Fort Wayne, Indiana in 1790. This was followed by devastating losses at St. Clair's Defeat in 1791. In 1792 the United States Army was reorganized into the Legion of the United States, with the 1st Infantry forming the nucleus of the 1st Sub-Legion. (Sub-Legions were the remote ancestors of today's Brigade Combat Teams, with organic Infantry, Cavalry and Artillery units.) On 20 August 1794, along with the most of the Legion's units under the command of Major General Anthony Wayne, the 1st Sub-Legion was engaged at the decisive victory of the Legion over the Miamis at the Battle of Fallen Timbers. In 1795 the Legion was reorganized along more traditional lines and reverted to being called the United States Army. In the reorganization the 1st Sub-Legion was redesignated as the 1st Infantry Regiment. As of 1805, six of the regiment's ten companies were in St. Louis, Missouri, with the other four located at Fort Massac, Fort Dearborn, Fort Adams, Mississippi and Fort Wayne in Detroit. War of 1812 and reorganization of the Army During the War of 1812 the 1st Infantry served in Upper Canada and saw action at the battles of Chippewa and Lundy's Lane. These actions give the regiment campaign credit for the War of 1812. After the end of the War of 1812 in early 1815, the Army had a total of 44 Infantry regiments which were consolidated into only eight regiments. Rather than preserving the existing designations of the Army's oldest units, it was decided instead to consolidate units based on their geographic proximity rather than seniority. On May 17, 1815, the 1st Infantry was consolidated with five
