In 1759 the 1st Battalion went with Gen. James Wolfe to Quebec City and the Battle of the Plains of Abraham serving in a support role followed by the Battle of Sainte-Foy and the subsequent siege of Quebec. Meanwhile, the 2nd battalion was with Gen. Amherst at the capture of Fort Ticonderoga and Fort St. Frédéric, driving the French from the Lake Champlain valley. In 1760, with the continuation of the 1759 Lake Champlain campaign, Col. Goffe commanded the New Hampshire troops who built the Crown Point Military Road from the Fort at Number 4 to the new English fort at Crown Point in forty days during the spring and at the Siege of Montreal and the fall of New France later that year.
