USS Eolus, an 368-ton (burden) side wheel steamship, was built at Newburgh, New York, for civilian employment, but was purchased by the Navy upon completion. Outfitted as a gunboat, she was commissioned in August 1864 and, following a brief search off the Atlantic Coast for the Confederate raider Tallahassee, joined the blockading forces off North Carolina. During October 1864 she captured the blockade runner Hope and assisted in the capture of the Lady Sterling. Late in the year and in mid-January 1865 Eolus took part in the attacks that captured Fort Fisher, thus closing the port of Wilmington to blockade runners. She continued operations in North Carolina waters from then until after the Civil War's end, and in June went north to Boston, Massachusetts, for decommissioning. USS Eolus was sold at the beginning of August 1865 and soon began a long career as a commercial steamer. She was broken up in 1894.
