The USS Argosy was a stern-wheel river steamer constructed in late 1862 to early 1863 in Monongahela, Pennsylvania. As a Civil War-era vessel, she was acquired by the Union Navy on 24 March 1863 and commissioned five days later. The ship was primarily used as a supply vessel and gunboat, playing a vital role in the Union blockade of Confederate waterways. Designed as a river steamer, Argosy was equipped for patrol and support duties along major rivers such as the Ohio, Tennessee, and Cumberland. Her dimensions and specific engineering details are not provided, but her role as a stern-wheel steamer indicates she was powered by a paddle wheel mounted at the stern, suitable for navigation on shallow, winding rivers. She was part of Lt. Comdr. Le Roy Fitch’s group of gunboats, patrolling these waterways to protect Union communication lines and restrict Confederate movement. Notable operations included her participation in expeditions up the Tennessee River, where she helped destroy vessels serving the Confederates and provided strategic support to Union forces. In May 1863, Argosy joined other gunboats in an expedition to Eastport, Mississippi, establishing a potential naval refuge for Union troops. Her service extended to routine patrols, escort duties, and small-scale raids, such as the destruction of a ferryboat at Bruinsburg in September 1863, where she also seized supplies and supplies meant for Confederate forces. Later in the war, Argosy served within the Mississippi Squadron, covering waters between New Orleans and Donaldsonville, Louisiana. Her most dramatic moment occurred in April 1865 when she attempted to intercept the Confederate steam ram Webb. After she was identified as a threat, her commanding officer set her ablaze on the riverbank, preventing her capture. Following the war, Argosy was decommissioned at Mound City, Illinois, on 11 August 1865, sold at auction, and returned to civilian service along the Mississippi River. She operated until her destruction by fire in Cincinnati, Ohio, on 7 March 1872. Her service exemplifies the vital role of river steamers in Union naval operations and blockade strategy during the Civil War.
