First American Regiment


The First American Regiment was the first peacetime regular army infantry unit authorized by the Continental Congress after the American Revolutionary War. Organized in August 1784, it served primarily on the early American frontier beyond the Appalachian Mountains. In 1815, following the end of the War of 1812, it was consolidated with several other regiments to form the 3rd Infantry Regiment.

Formation

After the conclusion of the American Revolution in 1783, Congress ordered the Continental Army to disband, and General George Washington resigned his commission as commander-in-chief. While the bulk of the Continental Army was disbanded by the end of 1783, Jackson's Continental Regiment, commanded by Colonel Henry Jackson and a company of artillery under Brevet Major John Doughty, remained in service. On June 2, 1784, Congress reissued the disbandment order, under the principle that "standing armies in time of peace are inconsistent with the principles of republican government, dangerous to the liberties of a free people, and generally converted into destructive engines for establishing despotism." Jackson's regiment was disbanded later that month and Doughty's Battery was retained at West Point guarding artillery and ammunition.
On June 3, 1784, Congress passed a new resolution:
Resolved, That the Secretary at War take order for forming the said troops when assembled, into one regiment, to consist of eight companies of infantry, and two of artillery, arming and equipping them in a soldier-like manner: and that he be authorised to direct their destination and operations, subject to the order of Congress, and of the Committee of the states in the recess of Congress.

Thomas Mifflin, the president of Congress, named his former aide, Josiah Harmar, to be the commander of the new regiment, with the rank of lieutenant colonel. Harmar was commissioned as the regiment's "lieutenant colonel commandant" on August 12, 1784. The new regiment was used primarily to man frontier outposts and guard against Native American attacks. An artillery company of the new regiment was Captain John Doughty's Company of the 2d Continental Artillery Regiment which had been attached to the 1st American Regiment.
The Regiment's first posting was to Fort McIntosh in Beaver, Pennsylvania.
In 1786, Secretary of War Henry Knox ordered Colonel Harmar to the outpost village of Vincennes to restore order. The Kentucky militia, who had been left behind by George Rogers Clark to help defend Vincennes but had become a lawless mob, fled at the approach of the Regiment. Colonel Harmar left 100 regulars under the command of Major Jean François Hamtramck to build a new fort and conduct operations deep within Indian Territory.

Northwest Indian War

The First American Regiment was renamed the Regiment of Infantry on September 29, 1789 when the United States Army was formally instituted under the Constitution of the United States. In 1790, Harmar – who had been breveted as a brigadier general in 1787 – led 320 regulars and over 1,000 militia on the disastrous Harmar Campaign in October 1790. The Regiment of Infantry suffered over 70 casualties.
An act of Congress on March 3, 1791 reorganized the U.S. Army to have two regiments of Infantry under the command of Major General Arthur St. Clair. As a result, the regiment was redesignated as the 1st Infantry Regiment with Colonel Harmar retained as its commanding officer. It comprised the main force of regulars under General St. Clair in the campaign to destroy Kekionga, a large Miami village central to the Western Confederacy of Native American nations.
While on campaign, the 1st Infantry under Major John Hamtramck was sent to find an overdue supply train. The supplies were never found, but as the Infantry marched to rejoin the main force on November 4, 1791, gunfire was heard. Native Americans under Miami Chief Little Turtle had attacked in what came to be known as St. Clair's Defeat, the worst loss to American Indians by the United States Army in history. Survivors broke through Little Turtle's lines and warned Major Hamtramck, who fell back to Fort Jefferson instead of covering the retreat.
In response to St. Clair's defeat, the Army was reorganized in 1792 as the Legion of the United States under Major General Anthony Wayne. The First Infantry was again re-designated, and became the Infantry component of the 1st Sub-Legion, commanded by Hamtramck, who was promoted to lieutenant colonel commandant. Under General Wayne's leadership, the Legion trained extensively before marching North to meet the Native American Confederacy that had defeated St. Clair. The Legion was victorious at the Battle of Fallen Timbers in 1794. The trading post at Kekionga was rebuilt and named Fort Wayne, and was garrisoned by the First Sub-Legion under Colonel Hamtramck. William Henry Harrison, later to become President of the United States, was a junior officer in the 1st Sub-Legion.

Later service

In October 1796, the Legion of the United States reverted to being named the United States Army and the 1st Sub-Legion was re-organized and re-designated as the 1st Infantry Regiment.
In 1803, Captain Meriwether Lewis of the 1st Infantry was appointed by President Thomas Jefferson to command the Corps of Discovery which conducted the Lewis and Clark Expedition to explore newly acquired territories of the United States.
During the War of 1812, the 1st Infantry served in Upper Canada and saw action at the battles of Chippewa and Lundy's Lane and the Siege of Fort Erie.

Consolidation

In October 1815, the 1st Infantry was consolidated with the 5th, 17th, 19th, and the 28th Infantry regiments to form the 3rd US Infantry Regiment. The 3rd Infantry, with its roots in the First Infantry Regiment, dating back to 1784, is recognized as the oldest Regular Army regiment in the United States Army.
