HMS Emerald was a 36-gun Amazon-class fifth-rate frigate of the Royal Navy, designed by Sir William Rule in 1794. Constructed at Northfleet dockyard, she was launched on 31 July 1795 and completed by October of that year. Her dimensions included a gun deck length of approximately 143 feet 2½ inches and a beam of 38 feet 4 inches, with a tonnage of about 933 tons burthen. The vessel was armed primarily with twenty-six 18-pounder long guns on her main deck, supplemented by eight 9-pounder guns on the quarterdeck and forecastle, along with eight 32-pounder carronades. Emerald's service history was marked by active participation in key naval campaigns of the late 18th and early 19th centuries. Her early deployments involved escort and patrol duties in the Mediterranean, where she was involved in hunting Spanish ships following the Battle of Cape St Vincent in 1797. Although she was not present at the battle itself, she was tasked with searching for the disabled Spanish flagship Santisima Trinidad afterward. In subsequent years, Emerald saw action in the Caribbean, notably during the invasion of St Lucia and Surinam in 1803, and participated in several engagements against French and Spanish vessels. She captured multiple privateers, including the French privateer Mosambique and the Dutch vessel Augusta, and contributed to the blockade of Cádiz. Emerald also played a role during the Battle of the Basque Roads in 1809, providing diversionary support and engaging enemy ships, including the destruction of French frigates in Conil Bay. Her operational duties included convoy escort, anti-privateer patrols, and participation in cutting-out expeditions, such as the attack on Apropos at Viveiro harbor. After her active combat service, Emerald was laid up in Portsmouth in 1811, later repurposed as a receiving ship in 1822, and ultimately broken up in January 1836. Her extensive career reflected her versatility and importance in British naval operations across various theaters during the Age of Sail.
