Awarded to Admiral Sir John Thomas Duckworth in 1804 by the Assembly of Jamaica.
The hilt of the sword consists of a gold lion's-head pommel and knuckle-bow guard made in the form of a serpent, with its head forming the quillon and its tail issuing from the lion's mouth. The gilt grip is embossed on each side with the arms of Jamaica.
It was issued for the protection he gave to local trade during his time as Commander-in-Chief of Jamaica, from 1803-05.
Despite being court-martialled twice, Admiral Duckworth led a long and very successful naval career. He served during the Seven Years' War, the American War of Independence, the French Revolutionary and Napoleonic Wars, as the Governor of Newfoundland during the War of 1812, and a member of the British House of Commons during his semi-retirement.
