The 1st New Hampshire Regiment was an infantry unit that came into existence on 22 May 1775 at the beginning of the American Revolutionary War. John Stark was the regiment's first commander. The unit fought at Chelsea Creek and Bunker Hill in 1775. On 1 January 1776, while engaged in the Siege of Boston, the unit was renamed the 5th Continental Regiment. In the spring it was sent to Canada where the New Hampshire soldiers fought at Trois-Rivières and later helped defend the area around Lake Champlain. Late in the year, the 5th Continental Regiment was transferred south to George Washington's main army where it fought at Trenton.
