peninsula, but they had left Sacket's Harbor defended only by a few troops, mainly militia. When reinforcements from the Royal Navy commanded by Commodore James Lucas Yeo arrived in Kingston, Yeo almost immediately embarked some troops commanded by Prévost and attacked Sackett's Harbor. Although the British were repelled by the defenders at the Second Battle of Sacket's Harbor, Chauncey immediately withdrew into Sacket's Harbor until mid-July, when a new heavy sloop-of-war had been completed. Chauncey sortied again on July 21 with 13 vessels. Six days later, he embarked a battalion of 500 troops commanded by Colonel Winfield Scott at Niagara. Chauncey sought to relieve the British-Native blockade of Fort George, by attacking British supply lines at Burlington Heights at the western end of Lake Ontario. Winfield Scott's force disembarked east of the heights at Burlington Beach (present-day Burlington) on July 29 but found the defenders too well entrenched for any assault to be successful. Anticipating Chauncey's intentions, Major-General Francis de Rottenburg, Sheaffe's successor as Lieutenant Governor, ordered the bulk of the troops at York to Burlington Heights. However, this left York largely undefended, as most of its militia were still on parole. The American squadron proceeded to York in order to seize food stores to feed its soldiers. The last remaining troop in York, members of the 19th Light Dragoons, collected the military supplies they could carry and withdrew along the Don River. The American landing of 340 men at York was unopposed, with the American force burning the barracks at the fort and the military fuel yards, and looting several properties. They also seized 11 batteaux, 5 cannons and some flour, before reembarking on their ships, leaving the settlement later that night. The library books that were looted from the battle in April 1813, were returned to the settlement during the second incursion into York. The Ontario Heritage Foundation erected a plaque in 1968 near the entrance to Coronation Park, Exhibition Place, Lake Shore Boulevard, in commemoration of the event. The plaque reads: On the morning of July 31, 1813, a U.S. invasion fleet appeared off York (Toronto) after having withdrawn from a planned attack on British positions at Burlington Heights. That afternoon 300 American soldiers came ashore near here. Their landing was unopposed: there were no British regulars in town, and York's militia had withdrawn from further combat in return for its freedom during the American invasion three
