The USS Benton was an ironclad river gunboat that served in the United States Navy during the American Civil War. Originally constructed as a center-wheel catamaran snagboat, she was converted in 1861 by James B. Eads in St. Louis, Missouri, into a formidable warship. Commissioned on February 24, 1862, Benton became a key part of the Western Gunboat Flotilla, serving as a flagship for much of her service. Her physical modifications included widening her lower deck into a gun deck and adding a second tier of accommodations, resulting in a large vessel well-suited for command roles. She was heavily armed, with her armament repeatedly upgraded throughout the war. Initially equipped with 9-inch smoothbore guns, she also carried antiquated 32-pounders and modified 42-pounder rifles, alongside a 12-pounder howitzer for close-quarters defense. By the war’s end, Benton was among the most heavily armed vessels in the Mississippi theater. The Benton’s service record was marked by participation in several significant battles and operations. She fought at the Battle of Island Number Ten in March–April 1862, and was present at the Battle of Plum Point Bend in May, where Union forces repelled a Confederate ram attack. She played a prominent role in the First Battle of Memphis in June 1862, leading to the routing of Confederate rams. In April 1863, under Admiral David Porter, Benton led a nighttime assault past Vicksburg’s defenses, taking multiple hits including a 10-inch shell that damaged her casemate. She also participated in the bombardment of Grand Gulf, MS, and supported Union operations along the Red River, although some campaigns, like the Red River expedition, ended in failure. Throughout her service, Benton hosted notable naval figures such as Admirals Andrew Foote and David Porter. Her durability and heavy armament made her a significant asset in riverine warfare, especially in the control of the Mississippi River and its tributaries. She decommissioned on July 20, 1865, and was sold later that year, marking the end of her notable career in Civil War naval operations.
