OLDMIXON. (Lieut., 1815. f-p., 14; h-p.,27.)
William Henry Oldmixon entered the Navy, 14 Oct. 1806, as Fst.-cl. Vol., on board the Tartar 32, Capts. Edw. Hawker and Stephen Poyntz, on the Halifax station. In the following Jan., after he had been for a brief period attached to the Meleager frigate, Capt. John Broughton, fitting at Chatham, he became Midshipman of the Agamemnon 64, Capt. Jonas Rose; under whom he was at first employed off Lisbon, then with the expedition against Copenhagen, and ultimately on the Brazilian station; where, in June, 1809, he removed to the Foudroyant 80, Capt. Rich. Turner Hancock. Joining, next, the Révolutionnaire 38, Capt. John Chas. Woolcombe, he served for some time in that ship on the north coast of Spain, and in Aug. and Sept. 1813 was employed in the batteries at the siege of St. Sebastian. From Dec. in the latter year until Aug. 1815, we find him officiating as Master’s Mate of the Columbia sloop, Capt. Henry Ducie Chads, and Shark receiving-ship at Port Royal, Jamaica, Capts. Jackson and Campbell. He was then (he had been promoted to the rank of Lieutenant by commission dated 24 Feb. 1815) appointed to the Onyx 10, Capt. Chas. Strangways, also on the West India station; whence, in April, 1816, he returned to England in the North Star 20, Capt. Geo. Bentham. His last appointment was, 18 Dec. 1841, to the office of Admiralty Agent on board a contract mail steam-vessel, which he retained until the spring of 1847. Agents – Messrs. Chard.
