The USS De Soto was a prominent wooden-hulled sidewheel steamship built in 1859 by Lawrence & Foulks of Brooklyn, New York, for Livingston, Crocheron & Co. She measured approximately 253 feet in length and displaced around 1,675 tons, making her one of the larger steamers of her era. Powered by a 65-inch bore, 11-foot stroke single-cylinder vertical beam engine, built by Morgan Iron Works, De Soto drove a pair of 30-foot sidewheels. This engine enabled her to reach speeds of up to 14 mph, a notable feat at the time, which contributed to her reputation for speed and reliability. She was equipped with a single forward-raked smokestack and carried two masts—one fore and one aft—supporting auxiliary square-rigged sails. Originally designed for passenger service between New York and New Orleans, with a stop at Havana, De Soto was a fast and sizable vessel, capable of making the trip in less than four days, and played a role in conveying mail, passengers, specie, and news across the route. She also served as a conduit for information, including reports of illegal slave ship interceptions. With the outbreak of the Civil War in 1861, De Soto was purchased by the U.S. Navy for $161,250 and converted into a gunboat at the New York Navy Yard. Her armament included a 30-pounder Parrott rifle and eight 32-pound guns. As USS De Soto, she was commissioned in November 1861 under Commander William M. Walker. Her service mainly involved patrolling Confederate blockade runners in the Gulf of Mexico, where her speed and shallow draft made her effective in capturing or destroying numerous blockade-running vessels—totaling eighteen during the war. Throughout her wartime career, De Soto participated in significant operations, including patrols along the Mississippi River, enforcement of the blockade, and engagements with Confederate vessels. Her operational history was marked by successful captures, occasional mishaps such as a collision with the French war steamer Milan, and periods of repair due to boiler wear and yellow fever outbreaks among her crew. Postwar, De Soto continued service in South American waters, notably in Haiti and the Dominican Republic, where she was involved in diplomatic and conflict-related activities. She was decommissioned in September 1868, resold to her original owners, and returned to commercial service. Her career ended in December 1870 when a fire, following a collision, caused her to burn to the waterline at McCalls Flat, resulting in the loss of her and her cargo valued at approximately $250,000. The USS De Soto remains a notable example of a versatile, fast wooden steamship that transitioned from civilian passenger service to a significant role in Union naval operations during the Civil War.
