HMS Duke of Gloucester (1807)

HMS Duke of Gloucester (or Gloucester) was a 10 gun brig of the Royal Navy which was launched at the Kingston Royal Naval Dockyard in Kingston, Ontario.

During the naval campaign in the War of 1812, H.M.S. Duke of Gloucester and H.M.S. Growler engaged the U.S. Schooner Julia at Sackets Harbour on July 19, 1812.

She was being repaired at York when the Americans briefly captured the colonial capital in 1813 during the War of 1812. She was sailed away, but British general Roger Hale Sheaffe ordered that her sister ship, HMS Sir Isaac Brock, was to be torched during the British retreat from York. This prevented the Americans from seizing the frigate. Gloucester was herself destroyed by the British a month later on 29 May 1813 in the Battle of Sackett's Harbor.
