The USS Wissahickon was a Unadilla-class gunboat constructed for the United States Navy during the American Civil War. Built in Philadelphia, Pennsylvania, she was commissioned in November 1861 and featured the typical design of her class, optimized for both riverine and coastal operations. During her service, the Wissahickon played a significant role in key naval campaigns. She initially operated in the Gulf of Mexico and along the Mississippi River, participating in the pivotal capture of New Orleans in April–July 1862. Her engagements included bombarding Grand Gulf, making two daring runs past Confederate fortifications at Vicksburg, and engaging the ironclad CSS Arkansas in combat. After undergoing repairs at Philadelphia from August to October 1862, she joined the blockade efforts along the southeastern coast, including South Carolina, Georgia, and eastern Florida. Wissahickon was actively involved in several notable actions, such as the bombardment of Fort McAllister, Georgia, in late 1862 and early 1863, and the destruction of the privateer Rattlesnake (formerly CSS Nashville) in February 1863. Her crew earned recognition for bravery, notably Captain of the Forecastle Henry Shutes, who received the Medal of Honor for his actions during this period. Throughout 1863, she destroyed blockade runners, including the SS Georgiana, and participated in the bombardments of Forts Wagner and Sumter off Charleston, South Carolina. Throughout the remainder of the Civil War, Wissahickon continued patrols off South Carolina and conducted inland water expeditions in Georgia. After the war concluded, she arrived in New York in June 1865, was decommissioned in July, and sold in October of the same year. She was subsequently renamed Adele and served as a merchant vessel for approximately two decades, extending her maritime service well beyond her military career.
