HMS Leopard was a 50-gun Portland class fourth-rate warship of the Royal Navy, launched from Sheerness Dockyard on 24 April 1790. Constructed over a decade after her initial order in 1775, she was built at Portsmouth and later at Sheerness, with her construction overseen by several master shipwrights. The vessel measured as a typical fourth-rate ship of her class, designed for versatile service during the late 18th and early 19th centuries. Her service record includes participation in significant naval operations during the French Revolutionary and Napoleonic Wars. In 1791, she escorted the China fleet of East Indiamen from Macao to Java Head, illustrating her role in protecting vital trade routes. Notably, on 24 October 1798, HMS Leopard captured the French privateer Apollon, and on 22 August 1800, she took the vessel Clarice. She also served actively in the Egyptian campaign of 1801, with her crew eligible for the Naval General Service Medal with the "Egypt" clasp. Leopard's most infamous incident occurred in 1807 when, while blockading French ships in Chesapeake Bay, her captain, Salusbury Pryce Humphreys, demanded to search the USS Chesapeake. When refused, Leopard opened fire, capturing four deserters and causing a diplomatic crisis with the United States—the Chesapeake-Leopard Affair—highlighting tensions that nearly led to war. In 1808, she escorted convoys from Portsmouth, and during the Mauritius campaign of 1809–1811, she was part of the Indian Ocean fleet. By 1812, her armament was removed, converting her into a troopship. Her final voyage ended in tragedy on 28 June 1814 when she grounded on Anticosti Island in heavy fog while en route from Britain to Quebec, carrying 475 Scots Guardsmen. The ship was wrecked, but all aboard survived. HMS Leopard's distinguished service and involvement in pivotal naval events underscore her maritime significance during a turbulent period of naval warfare.
