Roger's Rangers were part of William Haviland's force who marched from Lake Ontario in the west along the St Lawrence River and from upper New York via the Richelieu River in August. Along the way the Rangers fought to reduce the fortified French island of Île aux Noix. During the bombardment of the island Haviland sent Rogers' four ranger companies as well as light infantry and a force of Indians to drag three cannon through the forest and swamps further down to the rear of the French position. With much difficulty this was achieved and in a few days the guns were planted on the river-bank where a French naval force stood defending it. Rogers' cannon opened up upon these vessels surprising them; the closest sloop cut her cable and a strong west wind then drove her ashore into the hands of the British. The other vessels and gunboats made all sail downstream but stranded in a bend of the river, where the rangers, swimming out with their tomahawks, boarded and took one of them, and the rest soon surrendered. With their communications cut the French evacuated the island which then fell to the British. Soon after the Forts of Saint Jean and Chambly were burned by the French; the Rangers then led the final advance on Montreal which surrendered without a fight the following month.
