HMS Leven was a 20-gun sixth-rate post ship of the Cyrus class, constructed in Ipswich and launched on 23 December 1813. As a vessel of the Royal Navy, she measured typical for her class, though specific dimensions are not detailed in the provided content. Initially, she served during the final campaign of Napoleon Bonaparte, operating along the coast of La Vendee under Captain Buckland Stirling Bluett after her commissioning at Woolwich in October 1814. Following her decommissioning in 1816 at Chatham, HMS Leven was transferred to the Royal Navy’s Survey Service in August 1818. Under Captain David Ewen Bartholomew, she embarked on early survey missions along the west African coast and the Cape Verde Islands. Despite setbacks such as Bartholomew's death at Porto Praya in 1821, the vessel’s most notable service began under Captain William Fitzwilliam Owen, who took command in 1821. Owen’s expedition aimed to map the eastern coast of Africa, the southern Arabian Peninsula, Madagascar, and various Indian Ocean islands. During her survey voyage from 1821 to 1826, HMS Leven covered approximately 30,000 nautical miles and produced 83 charts, significantly advancing knowledge of the African coastline. Her crew’s efforts, however, came at a high cost, with many members succumbing to tropical diseases. The ship played a crucial role in regional security, capturing slave ships and supporting British military actions such as the First Anglo-Ashanti War. Notably, her crew found the brig Singapore near Delagoa Bay in Portuguese hands, with only one survivor due to disease, and successfully arranged for her cargo to be relanded and the vessel reloaded. After her survey service, Leven was decommissioned in February 1827 and converted into a hospital ship. She later served as a prison hulk at Chatham and a receiving ship at Limehouse before being broken up in July 1848. Her long and varied career underscores her maritime significance as a survey vessel, explorer, and auxiliary ship in the early 19th-century Royal Navy.
