The USS Mystic was a screw steamship originally built as Mount Savage in 1853 in Philadelphia, Pennsylvania. She had a burden tonnage of approximately 452 tons and was designed as a steam-powered vessel. In 1857, she was renamed Memphis, and in September 1858, she was chartered by the U.S. Navy, serving as USS Memphis during the Paraguay expedition of 1858–1859. The Navy purchased her outright in May 1859 and shortly thereafter renamed her USS Mystic. During her service, Mystic was actively involved in various maritime operations. Notably, while operating off the coast of Africa in June and July 1860, she captured two slave ships, contributing to anti-slavery efforts. With the outbreak of the American Civil War, Mystic was assigned to the Union Navy's blockade of the Confederate coastline along the Atlantic Ocean. Her duties included the pursuit and capture or destruction of blockade runners, among them the steamers Emma and Sunbeam, off the coast of North Carolina between June and September 1862. During this time, Mystic sustained damage in a collision with USS State of Georgia on September 28, 1862. Throughout 1863, Mystic supported Union military operations, including an expedition up the York River to assist Union Army actions and the seizure of a sailing vessel off Yorktown, Virginia. Her operational area primarily encompassed the Chesapeake Bay region, where she remained active until the end of the Civil War in 1865. Following her wartime service, Mystic was sold to private owners in June 1865. She was subsequently renamed General Custer and appears in merchant vessel registers until 1868, when she disappears from commercial records. The USS Mystic's service record highlights her versatile role in anti-slavery patrols, blockade enforcement, and supporting Union military campaigns during the Civil War, marking her as a notable vessel in mid-19th-century American naval history.
