The U.S. 4th Infantry Regiment ("Warriors") is an infantry regiment in the United States Army. It has served the United States for approximately two hundred years. History Origins It has been alleged that the regiment traces its lineage to the original Fourth United States Infantry, which was organized as the Infantry of the Fourth Sub-Legion on 4 September 1792, only four years after the adoption of the Constitution. The infantry of the Fourth Sub-Legion fought at Miami Rapids in 1794. In 1796, it was re-designated the Fourth Regiment of the Infantry. After ten years, due to a reduction in the army, the regiment was disbanded in 1802. However, according to the United States Army Center of Military History, this Fourth Infantry was a temporary unit with no lineal connection to either the original permanent 4th Infantry Regiment, or the modern 4th Infantry Regiment. See the lineage of the first 4th US Infantry below. Tecumseh's War In 1808, the Regular Army was reorganized to counter the increasing levels of resistance to colonization by Indian tribes living on the American frontier. The first permanent Regular Army unit to bear the designation of 4th Infantry Regiment was constituted on 12 April 1808 in the Regular Army, and organized from May to June of that year in New England. Led by General William Henry Harrison, the 4th Infantry, commanded by Colonel John Parker Boyd, was ordered to the Northwest Territory, which included modern-day Ohio, Indiana, and Illinois. Its mission was to defeat Tecumseh's confederacy, a pan-tribal confederation determined to resist the U.S. invasion of indigenous lands as part of a conflict which had raged since 1810; defeating the confederation would allow for white settlers to colonize the region without facing indigenous resistance. Harrison, would go on to serve as President of the United States, led a force consisting of the 4th Infantry supplemented by militiamen and volunteers against the confederacy at the Battle of Tippecanoe. During the battle, the American troops routed their Indian opponents, killing up to 80 Native Americans while suffering 188 casualties. Harrison then ordered his force to loot and burn the Shawnee settlement of Prophetstown; the Americans also desecrated the settlement's graveyard under his orders. The regiment subsequently returned to Fort Vincennes, and in 1812, after marching through Ohio, joined forces with General William Hull.
