The USS Lexington (1861) was a timberclad sidewheel gunboat built in Pittsburgh, Pennsylvania, in 1861. Constructed as a sidewheel steamer, she was subsequently purchased by the U.S. War Department and converted into a gunboat at Cincinnati, Ohio, under the supervision of Commander John Rodgers. Her design featured wooden hull construction typical of timberclads, optimized for riverine warfare during the Civil War. Throughout her service, Lexington played a vital role in Union operations along the Mississippi and Tennessee Rivers. She joined the Western Flotilla at Cairo, Illinois, and was actively engaged in multiple significant military actions. Notably, she participated in the seizure of the steamer W. B. Terry at Paducah, Kentucky, and supported General Ulysses S. Grant’s campaign by spearheading the Union drive to capture Paducah and Smithland, Kentucky, in September 1861. Her artillery proved effective in silencing Confederate batteries and covering troop advances, including during the Battle of Belmont, where her fire helped scatter Confederate reinforcements. Lexington was instrumental in the successful attack on Fort Henry in February 1862, pounding the fort’s defenses and contributing to its surrender. She continued river patrols, supporting Union advances and engagements, such as the Battle of Shiloh and operations along the White River and in Louisiana during the Red River Campaign. During these campaigns, she participated in notable actions like silencing shore batteries at Blair’s Landing, supporting the construction of a dam to save the fleet from the Red River rapids, and capturing Confederate steamers carrying cotton. Her construction and operational history exemplify the importance of rivergunboats in Union strategy, combining artillery support with mobility along inland waterways. She decommissioned in July 1865 at Mound City, Illinois, and was sold later that year. The USS Lexington’s service highlights her significance in controlling vital Confederate river routes and supporting major Union victories during the Civil War.
