HMS Melampus was a fifth-rate frigate of the Royal Navy, launched on 8 June 1785 after being ordered from James Martin Hillhouse of Bristol. Originally designed as a 38-gun vessel, her armament was reduced to 36 guns in January 1783 to improve crew comfort and operational efficiency. She measured approximately 1,130 tons burthen and was fitted for service at Plymouth after her launch. Her construction cost was roughly £20,785, with an additional fitting expenditure of about £2,985 in 1790. Throughout her service, Melampus was heavily engaged in combat and patrol operations during the French Revolutionary and Napoleonic Wars. She was first commissioned in 1790 under Captain Charles M. Pole, and after periods of being paid off and refitted, she re-entered service in 1793 under Captain Isaac Coffin. She participated in notable actions such as the capture of vessels during the action of 23 April 1794, and she was involved in the destruction of a French convoy at Cartaret Bay in May 1795. Melampus also captured several French privateers and ships, including the privateer Rayon in 1797, and the corvette Etna, which was renamed HMS Cormorant. Her notable engagements include the Battle of Tory Island in October 1798, where she fought in the main action and subsequently captured the Résolue. She continued capturing enemy vessels, such as the privateer Mercure in 1799 and the Spanish privateer Hydra in 1805. In her later years, under Captain Edward Hawker, she operated in North American waters, capturing the French brig Colibri in 1809 and the brig Bearnais in 1810, both of which were taken into Royal Navy service. In 1815, Melampus was sold to the Dutch government for £35,364. She served as the flagship of the Dutch squadron under Vice-Admiral T.F. van de Capellen during the bombardment of Algiers in August 1816, an action aimed at ending slavery practices there. Subsequently, by 1822, she was operating in the Dutch East Indies, leading a punitive expedition against the Iranun of Sulawesi. Her service record underscores her importance as a versatile and combat-proven vessel during a pivotal period of maritime conflict and colonial expansion.
