CSS Columbia Civil War Ironclad

Columbia was constructed under contract at Charleston, South Carolina in 1864, of yellow pine and white oak with iron fastenings and 6 inch (150 mm) iron plating. Hull work was done by F. M. Jones to John L. Porter's plans, plating and machinery by James M. Eason; her casemate was shortened to conserve precious metal and clad with 6" iron. Columbia was launched in March 1864 and entered service later in that year.
CSS Columbia, a 218-foot ironclad ram built at Charleston, South Carolina, was launched in March 1864 and entered service later in that year. On 12 January 1865, while on duty as part of the defenses of Charleston, she struck a sunken wreck near Fort Moultrie and suffered fatal damage. She was salvaged by Federal forces after they captured the city and in May 1865 was towed to Norfolk, Virginia. Her hulk was sold in October 1867.
