On March 31, 1814, the allied armies marched into Paris and with that came the collapse of Napoleon's empire. That was good news for Europe who had been fighting French armies for more than two decades, but it was bad news for the United States as with Napoleon's demise, Wellington’s veteran British regiments would now be freed up to fight in North America, and by mid-summer, four brigades of Wellington's best troops sailed from Bordeaux for Canada.

While General Henry Dearborn was trying to make headway along the Niagara front, the British were busy launching an offensive of their own against Sackett’s Harbor. This was not the first British attack on the American outpost, as the previous summer, on July 19, a British fleet had attempted to destroy Sackett’s Harbor’s critical navy yard, but the British were repulsed in that attack which marked the first armed engagement in the War of 1812.

In early May 1813, Commodore Isaac Chauncey loaded General Henry Dearborn’s army onto his waiting ships and sailed back across Lake Ontario for the second phase of Dearborn’s campaign, the capture of Fort George. Between the men stationed at Fort Niagara and Dearborn’s contingent, the American force consisted of roughly 4,000 men, with command of the army falling to 26-year-old Colonel Winfield Scott, destined to be one of the great military commanders in American history.
