The Continental Army was established by the Continental Congress on June 14, 1775 which is also recognized as the founding date of its successor, the United States Army. On that day, the Continental Congress assumed responsibility for militia regiments that had been raised by the colonies of New Hampshire, Massachusetts, Rhode Island, and Connecticut. Most of these troops were stationed outside Boston, Massachusetts, where they besieged the city occupied by British troops under the command of General Thomas Gage. The forces adopted by the Continental Congress amounted to 39 regiments of infantry, and 1 regiment and 1 separate company of artillery. The period of service for many of these regiments ended on December 31, 1775, although some had a service period that expired earlier. The Continental Congress resolved on June 15, 1775 that the Continental Army should be commanded by a full general. This appointment was offered to George Washington, who accepted it the following day. In company with Philip Schuyler and other officers he began the journey from Philadelphia to Boston.
On June 14 Continental Congress also for the first time ordered additional troops to be raised for national defense. It ordered that ten companies of "expert riflemen" be raised in Pennsylvania, Maryland, and Virginia, specifying their organization, pay, and term of enlistment.
As 1775 came to a close, with no end in sight to the siege of Boston and troops in Quebec preparing to attack Quebec City, Congress authorized a second establishment of the army, with a new regimental structure.
