HMS Duke of Gloucester was a 10-gun brig of the Royal Navy, constructed at Kingston Royal Naval Dockyard in Kingston, Ontario, and launched in May 1807. As a Provincial Marine vessel, she was designed with a shallow draft, allowing access to ports year-round on the Great Lakes and St. Lawrence River. The vessel measured approximately 165 tons burthen and was armed initially with ten 12-pounder guns, though by the War of 1812, her armament was reduced to six 6-pounder long guns, and she was rated as a schooner. Built under the supervision of Master Shipwright John Dennis, the Duke of Gloucester was intended primarily for transportation duties, supporting the colonial government and British Army logistics. Her role was initially limited to transporting provisions and personnel, reflecting her modest armament and size. During her service in the War of 1812, she participated in several naval engagements along Lake Ontario and the St. Lawrence River. In July 1812, under Lieutenant Francis Gauvreau, she was part of a British squadron that attempted to attack Sackett's Harbor; however, she remained offshore during the assault, which ultimately failed. Subsequently, she was involved in efforts to intercept American merchant vessels and enforce a blockade of Ogdensburg, New York. Her duties included patrolling and transporting supplies, with her operations primarily focused on Lake Ontario. By 1813, the vessel's hull had deteriorated, and she was unrigged for repairs at York, Upper Canada, with plans to increase her armament to 16 guns. During this period, she was captured by American forces when York was briefly taken in 1813. Renamed York, she was converted into a powder hulk at Sackett's Harbor and later damaged in the Battle of Sackett's Harbor in May 1813. Her service reflects the logistical and tactical challenges faced by naval forces operating on the Great Lakes during the War of 1812, embodying the critical role of smaller vessels in inland waters and colonial defense.
