Île aux Noix (French pronunciation: [il o nwa]) is an island on the Richelieu River in Quebec, close to Lake Champlain.Their army spent 10 days on the island: more than 900 American soldiers died from small pox and were buried in two mass graves on Isle aux Noix.The Île aux Noix Naval Shipyard was a Royal Navy yard from 1812 to 1834 in Quebec and served the RN's Lake Champlain fleet during the War of 1812.Amherst had not thought it wise to preserve the French fortifications on Île aux Noix and therefore he ordered the razing of the entrenchments to salvage the construction materials, which might be reused at Crown Point.During the War of 1812, the race for naval superiority in the area re-established the military importance of the island, which became the main support point for the British navy on this border.The flagship of the British squadron on Lake Champlain, HMS Confiance, a 36 gun 5th rate frigate, became the largest vessel ever constructed at Île aux Noix.The latter were further favoured by the activities of the Americans a short distance from the border, since the construction of Fort Montgomery provided the competent British authorities with an argument for supporting Île aux Noix.
