months earlier. The invaders seized food and military supplies, then re-embarked. The next day they returned to investigate collaborators' reports that valuable stores were concealed up the Don River. Unsuccessful in their search, the Americans contented themselves with burning military installations on nearby Gibraltar Point before they departed. Third incursion, August 1814 In the months after the second American incursion into York, the defences around the harbour were significantly improved, as the British needed to protect a four-vessel squadron that would be stationed at the town's harbour. On August 6, 1814, the American Lake Ontario squadron pursued HMS Magnet, before its captain set fire to the ship, preventing its capture. Suspecting the ship sailed from York, the American naval squadron made its way to the settlement in order to evaluate the situation, and discover if any more ships could be captured there. Arriving near York's harbour, the American squadron dispatched to negotiate under a white flag, in a ploy to evaluate the town's defences. However, the militia stationed at Fort York opened fire at the schooner, which returned fire, before withdrawing to rejoin the American squadron. The 8th Regiment of Foot, and the 82nd Regiment of Foot were sent to York in an effort to bolster the town's defences. The American squadron did not attempt to engage the newly built defences, although they remained outside York's harbour for the next three days before sailing away.

Historian, Charles Perry Stacey notes in the years before the war, American settlers had regularly settled into Upper Canada, with the colony essentially becoming a "transnational space," and the only distinction between Americans and Upper Canadians existing on paper. However, in the years after the war, Stacey notes a "deep prejudice against the United States," had emerged amongst the colony's settlers. Stacey further notes that the burning of York, and other American transgressions during the war, were later used by Canadian nationalists to create a national narrative that sees the "birth of the Canadian nation," as a result of the conflict. Several Canadian Army Reserve units perpetuate the linages of Fencibles, and militia units involved in the Battle of York, including the Stormont, Dundas and Glengarry Highlanders (Glengarry Light Infantry), the
