HMS Ethalion was a 36-gun frigate of the Royal Navy, launched in 1802 at Woolwich Dockyard and in service until her decommissioning in 1877. Constructed as a frigate, she was designed to carry a significant armament suitable for a range of naval operations during the Napoleonic Wars and beyond. Ethalion entered active service in 1803 under Captain Charles Stuart, initially operating in the North Sea. Throughout her career, Ethalion was engaged in various notable military actions. In May 1804, she captured the Dutch brig Union off Bergen. During 1807, command shifted to William Charles Fahie, who led Ethalion to the West Indies. There, she participated in the bloodless British invasions of Danish-held St Thomas and Santa Cruz in December 1807, under the squadron of Admiral Sir Alexander Cochrane. The vessel also captured the American vessel Washington on 26 October 1808 and was involved in the invasion of Martinique in 1809 under Captain Thomas John Cochrane. Ethalion played a role in the blockade of the Îles des Saintes in April 1809, which culminated in the capture of the islands. Though she was not directly involved in the assault, she shared in the proceeds of the conquest. After a brief period of paying off in 1810, she returned to service in 1811, operating off Lisbon and later in the Baltic Sea. Notably, on 12 April 1812, she, along with Clio, captured the Opsloe. During the War of 1812, Ethalion was active in capturing American vessels, including the seizure of several ships in August 1812 and the recapture of the Pomona off Ireland in December 1813. She continued her service off the Irish Coast in 1814 before being placed in reserve at Woolwich in 1816. In 1823, Ethalion was converted into a hospital ship, a role she served until the 1860s when she was repurposed as a breakwater. She was ultimately broken up in 1877, marking a lengthy career spanning over seven decades of service and adaptation, reflecting her significance in early 19th-century naval operations.
