 After the British and members of Tecumseh's Confederacy under Major General Isaac Brock had captured Detroit, "Nancy" carried troops, stores and provisions between Fort Erie and Detroit during the late summer and autumn.The following spring, on 23 April 1813 "Nancy" joined a small squadron in moving Major General Henry Procter's division from Amherstburg to Miami Bay, positioning them for what would be an unsuccessful Siege of Fort Meigs.On 9 September 1813, while "Nancy" was in Lake Huron on a trip to Fort Mackinac (which had been captured by a British force in the first few days of the war), the Americans won the decisive Battle of Lake Erie, capturing all the British armed vessels on the lake.
