High Quality Content by WIKIPEDIA articles! USS Antelope (1861) was a stern-wheel steamer acquired by the Union Navy for service during the American Civil War. Following the fall of that Confederate river fortress in the summer of 1863, Lavinia Logan seems to have returned to private hands for a time. In any case, the Union Navy acquired the vessel at Louisville, Kentucky, in the spring of 1864; and, on 26 May of that year, Rear Admiral David D. Porter wrote to Secretary of the Navy Gideon Welles reporting the purchase and recommending that her name be changed to Antelope. Apparently, he had acquired the ship to meet Rear Admiral Farragut's need for light-draft gunboats and had her hull covered with iron plates by naval shipfitters at Mound City, Illinois.
