MANSELL, Sir THOMAS (1777–1858), rear-admiral, son of Thomas Mansell of Guernsey, was born 9 Feb. 1777. He entered the navy in January 1793, on board the Crescent frigate with Captain James Saumarez [q. v.], whom he followed to the Orion, in which he was present in Lord Bridport's action off Lorient, at the battle of Cape St. Vincent, and at the battle of the Nile; after which he was promoted by Nelson to be acting-lieutenant of the Aquilon, a promotion which was confirmed by the admiralty to 17 April 1799. He subsequently served in the Channel and on the French coast, and at the reduction of the Cape of Good Hope, whence he was sent home by Sir Home Popham in command of an armed transport. He was flag-lieutenant to Sir James Saumarez in the Diomede, Hibernia, and Victory, and on 17 Sept. 1808 was promoted to the command of the Rose sloop, in which he took part in the capture of Anholt in the Baltic, 18 May 1809, and was at different times engaged with the Danish gunboats. In 1812 he was presented by the emperor of Russia with a diamond ring, in acknowledgment of his having piloted a Russian squadron through the Belt; and by the king of Sweden with the order of the Sword, 'in testimony of the esteem in which he held his services. In 1813 Mansell commanded the Pelican on the north coast of Spain, and on 7 June 1814 was advanced to post rank. It is stated that while in command of the Rose and Pelican he captured at least 170 of the enemy's vessels, some of them privateers of force. In 1837 he was nominated a K.C.H. and knighted. On 9 Oct. 1849 he became a rear-admiral on the retired list, and died in the early summer of 1868. In 1806 he married Catherine, daughter of John Lukis, a merchant of Guernsey, and by her had issue four daughters and four sons. These latter all entered the navy or marines. The second, Arthur Lukis, for some years commanded the Firefly, surveying ship, in the Mediterranean, and died, a retired vice-admiral, in 1890.
