American plan Late in 1813,
United States Secretary of War John Armstrong Jr. devised a plan to capture
Montreal, which might have led to the conquest of all
Upper Canada. Two divisions were involved. One would descend the
St. Lawrence River from
Sackett's Harbor on
Lake Ontario, while the other would advance north from
Plattsburgh on
Lake Champlain. The two divisions would unite in front of the city for the final assault. . He took command of the American forces around
Lake Champlain on 4 July 1813. The Americans around Lake Champlain were led by Major General
Wade Hampton I, who had taken command on 4 July 1813. Hampton had several misgivings about the plan. His own troops, encamped at
Burlington, Vermont, were raw and badly trained, and his junior officers themselves lacked training and experience. The British took over the sloops and used them in a raid against a number of settlements around Lake Champlain. In particular, they captured or destroyed quantities of supplies in and around Plattsburgh. Although the British crews and troops involved in the raid were subsequently returned to other duties, the American naval commander on the lake, Lieutenant
Thomas Macdonough, was unable to construct a flotilla of sloops and gunboats to counter the British vessels until August. Hampton, a wealthy southern plantation owner, despised Major General
James Wilkinson who commanded the division from Sackett's Harbor and who had a reputation for corruption and treacherous dealings with Spain. The two men, who were the two senior generals in the
United States Army after the effective retirement of Major General
Henry Dearborn on 6 July 1813, had been feuding with each other since 1808. Hampton at first refused to accept orders from Wilkinson, until Armstrong (who had himself moved to Sackett's Harbor) arranged that all correspondence regarding the expedition was to pass through the War Department.
Hampton's movements On 19 September, Hampton moved by water from Burlington to Plattsburgh, escorted by Macdonough's gunboats, and made a reconnaissance in force towards
Odelltown on the direct route north from Lake Champlain. He decided that the British forces were too strong in this sector. The garrison of
Ile aux Noix, where the British sloops and gunboats were based, numbered about 900 and there were other outposts and light troops in the area. Also, water on this route was short after a summer drought had caused the wells and streams to dry up, though this excuse caused some amusement among Hampton's officers as Hampton was known to be fond of drink. Hampton's force marched west instead to
Four Corners, on the
Chateauguay River. As Wilkinson's expedition was not ready, Hampton's force waited at Four Corners until 18 October. Hampton was concerned that the delay was depleting his supplies and giving the British time to muster forces against him. Hearing from Armstrong that Wilkinson's force was "almost" ready to set out, he began advancing down the Chateauguay River. A brigade of 1,400 New York militia refused to cross the frontier into Canada, leaving Hampton with two brigades of regulars numbering about 2,600 in total, 200 mounted troops and 10 field guns. Large numbers of loaded wagons accompanied the force. Hampton's advance was slowed because the bridges across every stream had been destroyed and trees had been felled across the roads (which themselves were little more than tracks).
Canadian counter-moves The Swiss-born Major-General
Louis de Watteville was appointed commander of the Montreal District on 17 September. In response to reports of the American advance, he ordered several units of militia called up. Reinforcements (two battalions of the
Royal Marines) were also moving up the St. Lawrence from
Quebec. Already though, the commander of the outposts, Lieutenant Colonel
Charles de Salaberry, had been organising his defences. In addition to his own corps (the
Canadian Voltigeurs) and George MacDonnell's 1st Light Battalion, he had called in several units of the
Select Embodied Militia and local militia units. two companies of the
Canadian Voltigeurs under Captain
Michel-Louis Juchereau Duchesnay and his brother Captain
Jean-Baptiste Juchereau Duchesnay, totalling about 100 men; a company from the 2nd Battalion Sedentary
Beauharnois Militia under Captain Longuetin (about 100) and perhaps two dozen Native Americans (
Abenaki,
Algonquin and
Iroquois) nominally commanded by Captain Lamothe. • To guard a ford across the Chateauguay behind the abatis, de Salaberry posted the light companies of the
2nd and 3rd Battalions of Select Embodied Militia under Captains de Tonnancoeur and Daly, and another company of Beauharnois militia under Captain Brugière (about 160 in total). De Salaberry had been so confident of victory that he had not informed his superiors of his actions. De Watteville and Sir George Prevost rode forward and "approved" de Salaberry's dispositions, even as the fighting started. ==Battle==
