The USS Donegal was a large sidewheel steamship constructed in 1860 in Wilmington, Delaware. Originally used as a Confederate blockade runner, she occasionally bore the name Austin during her service with the Confederacy. Her primary purpose was to facilitate trade and transport for the Confederacy, leveraging her size and steam-powered propulsion. During the American Civil War, the Union Navy captured Donegal off Mobile Bay on June 6, 1864, through the efforts of the USS Metacomet. Following her capture, she was sent to Philadelphia for condemnation and subsequently purchased by the Union Navy. She was fitted for service at the Philadelphia Navy Yard and commissioned into the Union fleet on September 3, 1864, under the command of Acting Volunteer Lieutenant W. H. West. Once in Union service, Donegal was assigned to patrol the navigable waterways of the Confederacy to enforce blockades and prevent the South from trading with foreign nations. Her initial voyage took her down the Delaware River to Charleston, South Carolina, carrying supplies and personnel for the South Atlantic Blockading Squadron. She made several similar voyages between September and December 1864, returning to Philadelphia multiple times. In 1865, Donegal continued her patrols along the coasts of South Carolina and Georgia. Notably, she participated in rescue operations, saving the crew of the USS Commodore McDonough after it sank on August 23, 1865, while being towed to New York. She arrived in New York City on August 24, 1865, and was decommissioned on September 8, 1865. Shortly thereafter, she was sold on September 27, ending her service with the Union Navy. Overall, USS Donegal played a significant role in Union naval efforts to blockade the Confederacy, exemplifying the use of captured vessels in wartime maritime strategy.
