The USS Cincinnati was a city-class ironclad gunboat built in 1861 in St. Louis, Missouri, under a War Department contract by James Eads. Commissioned on January 16, 1862, at Mound City, Illinois, the vessel was a stern-wheel casemate ironclad designed for riverine warfare during the American Civil War. She was assigned to the Western Gunboat Flotilla under Flag Officer Andrew H. Foote, serving primarily on the Mississippi River and its tributaries. Constructed as an iron-hulled vessel, Cincinnati played a vital role in key Union campaigns. She participated in the capture of Fort Henry in February 1862, operations against Island No. 10, and engagements at Plum Point Bend and Fort Pillow, where the ship was repeatedly struck by enemy rams and eventually sunk during the engagement. The vessel was raised and returned to service, continuing operations against Confederate positions such as Arkansas Post and the White River in early 1863. One of Cincinnati’s notable actions occurred during the Siege of Vicksburg in May 1863. Ordered to destroy two Confederate artillery guns obstructing Sherman's flank, Cincinnati encountered a well-concealed heavy artillery battery atop a bluff. As Cincinnati approached, the Confederate "Arkansas Battery" opened fire, scoring a direct hit that penetrated her magazine and disabled her steering. The vessel was soon beached and abandoned after taking on water, but her crew displayed remarkable bravery. Several sailors swam back to assist wounded comrades under fire, with six crew members later receiving the Medal of Honor for their heroism. Repaired in August 1863, Cincinnati resumed patrol duties along the Mississippi River until early 1865, after which she was transferred to the West Gulf Blockading Squadron, patrolling off Mobile Bay and the Mississippi Sound. She was decommissioned on August 4, 1865, at Algiers, Louisiana, and subsequently sold in New Orleans on March 28, 1866. The USS Cincinnati remains a significant vessel for its contributions to Union riverine operations and its demonstration of naval bravery during the Civil War.
