HMS Mercury was a 28-gun Enterprise-class sixth-rate frigate of the Royal Navy, constructed during the American War of Independence. Ordered from Peter Mestaer at the King and Queen Shipyard in Rotherhithe, she was laid down on 25 March 1778 and launched on 9 December 1779. She was completed by 24 February 1780 at Deptford Dockyard, with her construction costing a total of £13,603 8s, including fitting and coppering. Designed as a sixth-rate frigate, Mercury featured a typical armament of 28 guns. She was commissioned in October 1779 under Captain Isaac Prescott, and her early service involved cruises to Newfoundland, where she notably retook the ship Elizabeth in July 1780. Mercury participated in George Johnstone’s squadron, capturing French vessels such as the Philippine in September 1781 and the privateer Bologne in March 1782. She also recaptured the ship Aimwell off Scilly in January 1800. Throughout the 1780s and early 1790s, Mercury served in North American waters, including Nova Scotia, escorting merchant vessels and engaging in various captures. She was briefly fitted as a floating battery in 1803 and participated in operations against Spanish shipping, notably capturing the Spanish gun-vessel Fuerte de Gibraltar in February 1805. During the Napoleonic Wars, Mercury saw active service in the Mediterranean, Adriatic, and off the Spanish coast. She engaged in several notable actions, such as destroying Spanish vessels, cutting out French schooners like Pugliese in 1808, and participating in attacks on coastal towns like Pesaro and Cesenatico. She also captured multiple privateers and smaller vessels, often in chases lasting several hours. In 1810, Mercury was converted into a troopship, and she continued service in the Leeward Islands and off Lisbon. Her final notable action was sharing in the capture of the American ship Fame in July 1813. Mercury was broken up at Woolwich in January 1814, marking the end of her active career. Her service record exemplifies the versatility and durability of the Enterprise-class frigates in late 18th and early 19th-century naval warfare.
