Description

Battle of Lacolle National Historic Site of Canada is located within a suburb of the town of Lacolle, Quebec, just north of the border between Canada and the United States. In March 1814, a small force composed of the British garrison the 13th Regiment of Foot, Royal Marines, Canadian Fencibles, Voltigeurs and Aboriginal warriors withstood an attack by 4,000 American soldiers. Resistance to the American forces centred at the local mill on the river’s southern bank and a blockhouse 200 metres away on the northern bank. The mill’s location on the Lacolle River is marked by an HSMBC cairn next to the road. Official recognition refers to a 150 meter radius from the centre of the bridge on route 223 that crosses the Lacolle River.

Heritage value

The Battle of Lacolle was designated a national historic site of Canada in 1923 because:

  • The Battle of Lacolle Mill ended the last American invasion of Lower-Canada during the War of 1812.

The Battle of Lacolle, the final battle against the American invasion of Lower-Canada during the War of 1812, is valued for its associations with the protection of Canada. Following a previously unsuccessful attempt to march into Montreal in 1812, Major-General James Wilkinson planned an American invasion of Lower-Canada for March 1814. Major-General Wilkinson crossed the frontier with an army of 4 000 men and headed towards the Lacolle River where he had been defeated in 1812. On March 30th 1814, the Americans opened fire on the mill near the Lacolle River where Major R.B. Handcock led a small force of approximately 500 men. This force comprised a small British garrison of the 13th Regiment of Foot, Royal Marines, Canadian Fencibles, Voltigeurs and Aboriginal warriors. Major Handcock’s forces withstood the attack on the fortified mill. Daunted by Major Handcock’s resistance, Major-General Wilkinson gave up his incursion and retreated to the American border, thus ending the last American invasion of Lower Canada during the War of 1812.
