HMS Seahorse was a 38-gun Artois-class fifth-rate frigate of the Royal Navy, launched in June 1794 and decommissioned and broken up in 1819. Constructed as part of the Artois class, she was a relatively nimble vessel designed for versatility and speed. Her armament of 38 guns made her suitable for a variety of roles, including patrol, escort, and combat operations. Commissioned in July 1794 under Captain John Peyton for service on the Irish Station, Seahorse quickly became active in early engagements. Notably, in August 1796, she participated in the capture of the privateer cutter Calvados, and shortly thereafter, she helped seize the privateer Indemnité and the Brazilian ship Santa Cruz in August and September 1796. She also took part in Rear Admiral Nelson's attack on Santa Cruz in July 1797. In June 1798, Seahorse engaged and captured the French frigate Sensible in the Strait of Sicily. During her service, Seahorse operated off the coast of Egypt and the Mediterranean, including participation in Vice-Admiral Hood's squadron near Alexandria in August 1798. She was involved in the destruction of the French aviso Anemone in September 1798, demonstrating her role in cutting-edge naval actions of the period. Seahorse also served as the flagship for Rear-admiral Sir Richard Bickerton in 1800 and escorted convoys to Bengal in 1801. Throughout her career, Seahorse saw numerous engagements, including action against Ottoman and French vessels, such as the capture of the Neapolitan privateer Stella di Napoleon in 1810 and the engagement with the French brig Renard. She sank the privateer lugger Subtile in November 1813 after a prolonged chase, with significant loss of life among her enemies. In the War of 1812, Seahorse participated in major actions along the American coast, including the Battle of Baltimore in September 1814 and operations at Lake Borgne. She was involved in the capture and destruction of enemy vessels and contributed to the British efforts in North America before returning to Portsmouth in 1815. She was ultimately broken up in July 1819, marking the end of her nearly 25 years of distinguished service.
