The USS Lafayette was a notable Union Navy vessel that served during the American Civil War, originally constructed in 1848 in St. Louis, Missouri, as the side wheel steamer Aleck Scott. She was later purchased by the War Department on 18 May 1862, and converted at St. Louis into an ironclad ram by Edward Hartt. Renamed Lafayette on 8 September 1862, she was transferred to the U.S. Navy with the western flotilla on 1 October 1862 and commissioned at Cairo, Illinois, on 27 February 1863 under Captain Henry A. Walke. Lafayette's most significant contribution was her participation in the pivotal naval operations supporting the Union effort to seize Vicksburg. She joined Rear Admiral David Dixon Porter’s Mississippi Squadron and was involved in the daring dash past Confederate batteries on 16 April 1863, a key moment in the campaign that contributed to the fall of Vicksburg and control of the Mississippi River. During this action, Lafayette, lashed to the ram General Sterling Price for protection, endured nine effective hits through her casemate and lost her coal barge, yet she and her squadron successfully passed the defenses under heavy fire, demonstrating the effectiveness of ironclad river warfare. Throughout the campaign, Lafayette participated in reconnoitering Confederate fortifications, engaging in battles at Grand Gulf, and supporting Union troop landings. She was instrumental in the Union’s strategic movements along the river, including pushing past obstructions and supporting land forces at key points like Alexandria and Shreveport. After the fall of Vicksburg on July 4, 1863, Lafayette patrolled the Mississippi and its tributaries, aiding in the protection of Union communications and transportation. Decommissioned on 23 July 1865 and laid up in New Orleans, Lafayette was sold there on 28 March 1866. Her service exemplifies the crucial role of ironclad gunboats in the Union’s riverine warfare strategy, contributing decisively to the control of the Mississippi River and the broader Union victory.
