On June 3, 1784, the day after the Continental Army was reduced to 80 men, the Congress established a regiment which was to be raised and officered by obtaining volunteers from the militia of four of the states. This unit, the First American Regiment was commanded until 1 January 1792 by Josiah Harmar of Pennsylvania, gradually turned into a Regular regiment known as the 1st Infantry in 1791, and in 1815 was it redesignated as the 3d Infantry in the reorganization of the army following the War of 1812. Congress gradually increased the military establishment from 700 men in 1784 to 5,104 in 1793.
