Battle of The Chateauguay - Aftermath

Aftermath

Having reunited his forces, Hampton held a council of war. This unanimously concluded that a renewed advance stood no chance of success. Furthermore, the roads were becoming impassable under the autumn rains, and Hampton's supplies would soon be exhausted. Hampton ordered a withdrawal to Four Corners and sent Colonel Atkinson to Wilkinson with a report of his situation.

Wilkinson's own force had reached a settlement named Hoags, on the Saint Lawrence River a few miles upstream from Ogdensburg, when they received this news. Wilkinson replied with orders for Hampton to advance to Cornwall, bringing sufficient supplies for both his own and Wilkinson's division. When he received these orders, Hampton was convinced that they could not be executed and declined to comply, retreating instead to Plattsburgh. Before Hampton's reply could reach Wilkinson, the latter's own force was defeated at the Battle of Crysler's Farm on 11 November. Wilkinson nevertheless used Hampton's refusal to move on Cornwall (which he received by letter on 12 November) as a pretext to abandon his own advance, and the campaign to capture Montreal was called off.

Hampton had already submitted his resignation the day before the battle of Chateauguay, in his reply to Armstrong's letter of 16 October. He was not employed again in the field.

On the British side, the victorious troops at Chateauguay held their existing positions and endured much discomfort for several days before Indians reported that the Americans were retreating, which allowed them to retire to more comfortable billets. The hot-tempered de Salaberry was furious that Major General de Watteville and especially Sir George Prevost had arrived on the field too late to take part in the fighting but in time to submit their own dispatches claiming the victory for themselves. He considered resigning his commission but was later officially thanked by the Legislative Assembly of Quebec. He and Lieutenant Colonel MacDonnell were made Companions of the Bath after the war for their parts in the battle. Sir George Prevost's dispatch, which claimed that 300 Canadians had put 7,500 Americans to flight nevertheless contributed to the battle becoming legendary in Canadian folklore.

Eight currently active regular battalions of the United States Army (1-3 Inf, 2-3 Inf, 4-3 Inf, 1-5 Inf, 2-5 Inf, 1-6 Inf, 2-6 Inf and 4-6 Inf) perpetuate the lineages of several of American infantry regiments (the old 1st, 4th, 25th and 29th Infantry Regiments) that took part in the Battle of the Chateauguay.

The site was designated a National Historic Site of Canada in 1920.
