The USS Mist was a stern wheel steamer constructed in 1864 at Allegheny, Pennsylvania, serving as a key vessel for the Union Navy during the final months of the American Civil War. Purchased by the Union Navy on December 23, 1864, in Cincinnati, Ohio, the ship was commissioned on March 3, 1865, at Mound City, Illinois, under the command of Acting Master W. E. H. Fontress. Originally built as a civilian vessel, the Mist underwent a conversion into a tinclad gunboat during the first four months of 1865, equipping her for military service on the Mississippi River. Physically, the Mist was a stern wheel steamer, a design favored for river operations, with a shallow draft suitable for navigating the Mississippi and its tributaries. As a tinclad vessel, she was armed with light artillery intended for patrol and escort duties rather than heavy combat. Her primary role was to enforce Union blockades and protect vital waterways against Confederate threats, such as desperadoes and other hostile elements. Assigned to the 8th District within the Mississippi Squadron, the Mist patrolled the river to safeguard steamers and settlements, contributing to the Union’s control of the Mississippi River. Her service was relatively brief; she was decommissioned on August 4, 1865, at Mound City, shortly after the end of the Civil War, and was sold at public auction to C. C. Hutchinson on August 17, 1865. Subsequently, she was documented as a merchant vessel, continuing to serve American commerce on the Mississippi River and its tributaries until 1874. The USS Mist’s significance lies in her role as part of the Union’s river patrol fleet, helping to secure vital supply routes and maintain Union control of the Mississippi during a critical period in American history.
