Prince Regent was a schooner constructed for Upper Canada's Provincial Marine for use on Lake Ontario. Built just before the beginning of the War of 1812, the vessel took part in the attack on Sackett's Harbor, New York. With the arrival of the Royal Navy in the Great Lakes under the command of Commodore James Lucas Yeo in 1813, the vessel was renamed HMS Lord Beresford or General Beresford, or Beresford. The British detachment on the lake engaged the American naval squadron and attacked American positions in the Niagara region, while supporting British armies.
