USS Fulton was a steamer that served the U.S. Navy prior to the American Civil War, and was recommissioned in time to see service in that war. However, her participation was limited to being captured by Confederate forces in the port of Pensacola, Florida, at the outbreak of war. The second ship to be named Fulton by the Navy, a side wheel steamer, her build commenced in 1835, and she was launched 18 May 1837 by Brooklyn Navy Yard; and commissioned 13 December 1837, Captain M. C. Perry in command. She was often called Fulton II. Fulton I was the renamed floating battery Demologos. Service in the North Atlantic Fulton cruised the Atlantic coast, aiding ships in distress, conducting ordnance experiments, and training officers in gunnery. A major event of her early service came on 23 November 1838, when she bested the British steamer in a speed contest off New York. In 1841, Captain John T. Newton was in command of Fulton. Experiments in gunnery and projectiles were conducted aboard under the direction of Captain M. C. Perry; during one such experiment, a gun burst, killing several men and wounding others. Newton had been aboard with Commodore Isaac Chauncey, who was inspecting the ship, and the two had left "only 10 or 15 minutes before the explosion". Decommissioned at New York 23 November 1842, Fulton lay in ordinary until 1851, when she was rebuilt and her machinery completely replaced. 1851 rebuild The third Fulton rebuild commenced in 1850, was launched on 30 August 1851, at the Brooklyn Navy Yard. Fulton was essentially a harbor defense ship and was unsuitable for the cruising missions then emphasized by Navy policy. Accordingly, the New York Navy Yard rebuilt her in 1851 as a much more conventional warship. Fulton was recommissioned 25 January 1852 for duty in the Home Squadron, and sailed from New York 22 February for the West Indies. After the rebuild she was commonly referred to as Fulton III. During the next six years, aside from necessary repair periods in the yards at Washington, D.C., Norfolk, Virginia, and Boston, Massachusetts, Fulton ranged from the Caribbean to the Gulf of St. Lawrence, transporting Government officials, protecting merchantmen against search on the high seas, and joining in the search for (January through May 1855) and the expedition to Nicaragua in 1857 to break up William Walker's filibustering activities.
