The USS Pembina was a Unadilla-class screw gunboat constructed for the Union Navy during the American Civil War. Built by Thomas Stack and Novelty Iron Works in New York City, she was commissioned on October 16, 1861. As a typical vessel of her class, she was designed for agility and versatility in naval operations, featuring a screw propeller propulsion system suitable for patrolling and combat duties in confined or shallow waterways. Upon commissioning, the USS Pembina quickly joined the South Atlantic Blockading Squadron, engaging in a series of significant early actions. By November 5, 1861, she participated in dispersing a Confederate squadron in Port Royal Sound alongside ships such as Ottawa, Seneca, and Pawnee. She played a key role in the bombardment of Fort Beauregard and Fort Walker, contributing to their eventual abandonment. She also supported the occupation of Beaufort, South Carolina, on November 9, 1861. Throughout late 1861 and early 1862, Pembina operated extensively along the Georgia and South Carolina coasts. She penetrated Wassaw Sound to assist in blockading Savannah, Georgia, and engaged Confederate positions at Port Royal Ferry. She was instrumental in clearing mines from the Savannah River near Wright’s River between January and February 1862. Her duties included escorting transports, covering troop landings, and supporting Union operations against Confederate forces. In June 1862, she seized her first prize, the schooner Rowena, in the Stono River. She continued her blockade and patrol operations along the Gulf Coast, capturing a sloop, Elias Beckwith, near Mobile, Alabama, on April 23, 1863. Her final prize was the Dutch brig Geziena Hilligonda, captured off Brazos Santiago, Texas, on December 4, 1864, carrying supplies such as medicines, iron, and cloth. After the Civil War, the USS Pembina returned to the U.S. East Coast and was decommissioned at the Washington Navy Yard on September 22, 1865. She was sold in New York City on November 30, 1865. Her service exemplifies the vital role of small, agile gunboats in blockading and controlling Confederate waterways during the Civil War.
