John Ludlow Nelson Sealy entered the Navy, 21 July, 1817, as Fst.-cl. Vol., on board the Ganymede 26, Capt. Hon. Robt. Cavendish Spencer, with whom he continued employed as Midshipman in the Mediterranean and South America until transferred, in Sept. 1822, to the Cherokee 10, Capt. Wm. Keats, on the Leith station. Being again, in April, 1823, placed under the orders of Capt. Spencer in the Naiad 46, he returned to the Mediterranean, where he contributed, 31 Jan. 1824, to the utter defeat of the Tripoli Algerine corvette of 18 guns and 100 men, and aided in the boats under Lieut. Michael Quin at the brilliant destruction, on the night of 31 May following, of a 16-gun brig, moored in a position of extraordinary strength alongside the walls of the fortress of Bona, in which was a garrison of about 400 soldiers, who, from cannon and musket, kept up a tremendous fire almost perpendicularly on the deck. After serving for about a year and 10 months, still in the Mediterranean, on board the Zebra 18, Capts. Edw. Rich. Williams and Chas. Cotton, he was there nominated, 28 Nov. 1827 (he had parsed his examination 4 Dec. 1823), Acting-Lieutenant of the Raleigh 18, Capt. John Burnet Dundas. From that sloop, to which the Admiralty confirmed him 9 Jan. following, he removed, in April, 1828, to the Ocean 80, Capt. Patrick Campbell, also on the Mediterranean station, whence, in May, 1830, he returned to England. His last appointment was, 2 Sept. 1832, to the Tyne 28, Capt. Chas. Hope, with whom he served in the Pacific until paid off in Jan. 1834.
