The USS Cayuga was a Unadilla-class gunboat constructed for the United States Navy during the Civil War. Launched on October 21, 1861, by S. Gildersleeve and Sons in Portland, Connecticut, she was outfitted at the New York Navy Yard and officially commissioned on February 21, 1862, under the command of Lieutenant N. B. Harrison. Designed for blockading operations, she measured as a typical Unadilla-class vessel, which were known for their relatively small size, speed, and maneuverability, though specific dimensions are not detailed in the source. Cayuga was primarily assigned to the West Gulf Blockading Squadron, arriving at Ship Island in Mississippi Sound on March 26, 1862. Her service focused on the lower Mississippi River, its tributaries, and the Gulf coast of Texas. The vessel only left this area once, from May 1 to July 8, 1862, when she underwent repairs at the New York Navy Yard. During her deployment, Cayuga played a vital role in the Union blockade, capturing numerous vessels including schooners Jesse J. Cox, Tampico, J. T. Davis, Wave, and the sloop Blue Bell, as well as sharing in the capture of the sloop Active. Cayuga participated in the significant engagement with Forts Jackson and St. Philip in April 1862, contributing to the Union's victory at New Orleans. Her crew earned three Medals of Honor for bravery in this battle: Captain of the Afterguard William Parker, Quartermaster Edward Wright, and Boatswain’s Mate William Young. Additionally, she bombarded Donaldsonville, Louisiana, on August 9, 1862. On April 18, 1863, at Sabine Pass, Texas, her commanding officer, Lieutenant Commander David McDermut, led a reconnaissance mission that ended tragically when Confederate forces surprised the party, resulting in McDermut being mortally wounded and six men captured. Cayuga’s active service concluded after her departure from Galveston, Texas, on July 4, 1865, and she arrived in New York on July 26. She was decommissioned shortly thereafter on July 31, 1865, and sold on October 25 of the same year. Her service exemplifies the vital role played by Unadilla-class gunboats in the Union blockade and their contribution to the Union's naval dominance during the Civil War.
