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.
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.
On 1 January 1777 the unit was renamed the 1st New Hampshire Regiment and it saw action at Princeton before being sent back to the Northern Department.
The regiment was adopted into the Continental Army on 14 June 1775, and assigned to General John Sullivan's brigade on 22 July 1775.
