Navy veteran Sir Thomas Staines was appointed her first captain on 7 May 1812 but did not join the ship until 17 June 1813 owing to his being at sea aboard HMS "Hamadryad". After a period of cruising in the Bay of Biscay, the vessel set sail for South America where during the course of several missions she unexpectedly encountered the last member of the crew that had seized HMS "Bounty" from its captain Lieutenant William Bligh during the 1789 mutiny aboard the ship. With the coming of the Pax Britannica in 1815, "Briton" undertook various voyages before she was broken up in 1860.
