On 2 September she departed New York for Fort Monroe where she joined with steamer in intercepting a British arms shipment from Bermuda to Wilmington, North Carolina. While sailing from Bermuda on 16 September a boiler burned out and forced her to repair at New York. In December 1863 Fort Jackson was assigned to the North Atlantic Blockading Squadron to cruise off the Western Bar, Cape Fear, and the following month helped in destroying the grounded blockade runnerBendigo at Folly Inlet. In April, Captain Benjamin F. Sands, her commanding officer, organized a boat expedition in which her crew crossed the bar to Masonboro Sound and destroyed valuable State salt works, and seized a number of prisoners. The steamer captured the blockade runner Thistle in June and took the runner Boston as prize during the next month. The success of her voyage was heightened when in the same period she plucked drifting cotton bales and bags from the sea and sent them to Philadelphia for adjudication. During October she was attached to the 2nd Division North Atlantic Blockading Squadron and on 21 October captured CSS Wando attempting to run through with a cargo of cotton. During December Fort Jackson fought in the battle off Wilmington and in the first bombardment of Fort Fisher during which she covered troop landings and received on boardthe dead and wounded. After loading supplies for the fleet at Fort Monroe and Norfolk, Virginia, she returned in mid-January 1865 to cannonade Fort Fisher until its surrender on the 15th. On 1 February she was transferred to the West Gulf Blockading Squadron, underwent repair at Pensacola, Florida, and took up station on the Texas coast. She aided steamer in capturing the schooner Chaos off Galveston during April, and was present at the surrender of Forts Point and Magruder in June. Fort Jackson returned to New York where she was decommissioned on 7 August 1865 and later sold 27 September 1865. She subsequently became the commercial steamer North America and was not broken up until 1879. As of 2005, no other ship in the United States Navy has borne this name.
