The USS Wasp (1865) was a sidewheel gunboat constructed from an iron-hulled steamer originally named Emma Henry. She was captured at sea in December 1864 while attempting to run the Union blockade of the Confederacy. The U.S. Navy purchased her from the New York prize court on January 13, 1865, and commissioned her into service on May 11 of the same year. Her construction featured a traditional sidewheel propulsion system, characteristic of mid-19th-century steam-powered vessels, and an iron hull that provided increased durability. Initially, USS Wasp joined the squadron commanded by Acting Rear Admiral Sylvanus W. Godon at Norfolk, Virginia. This squadron was tasked with locating the Confederate ironclad ram CSS Stonewall. Wasp departed Hampton Roads on May 17, 1865, and on May 22, she transported Acting Rear Admiral Godon into Charleston harbor for a conference with Rear Admiral John A. Dahlgren. During this mission, she collided with another ship, necessitating repairs at Philadelphia, Pennsylvania. In June 1865, while undergoing repairs, she was renamed USS Wasp. After her repairs, she rejoined Rear Admiral Godon’s squadron, which had been reassigned to the Brazil Squadron based at Rio de Janeiro. The original mission against the CSS Stonewall was rendered moot when the ironclad surrendered to Spanish authorities in Cuba, but Wasp’s new assignment involved protecting American interests along South America’s eastern coast and in Africa. During the Paraguayan War (1864–1870), Wasp operated mainly around the Rio de la Plata, Uruguay, Paraná, and Paraguay Rivers, supporting American interests and transporting diplomats. Her duties included patrolling rivers and ascending inland waterways as far as Asunción, Paraguay. After the conflict concluded in June 1870, she remained based in Montevideo, continuing her patrols and diplomatic duties until she was deemed unfit for service in 1876. She was decommissioned and sold on June 5, 1876. The USS Wasp’s service exemplifies mid-19th-century naval deployment, combining riverine and coastal operations in support of American foreign interests during a period of regional conflict and geopolitics.
