context_page_description: The Floating Battery of Charleston Harbor was an ironclad vessel that was constructed by the Confederacy in early 1861, a few months before the American Civil War ignited. Apart from being a marvel to contemporary Charlestonians, it was a strategic naval artillery platform that took part in the bombardment of Fort Sumter on April 12 and April 13, 1861, making it the first floating battery to engage in hostilities during the Civil War.
context_section_description: The battery was constructed on the waterfront of Charleston, South Carolina in view of the Union forces at Ft. Sumter near the mouth of Charleston harbor. Construction began in January 1861, under the leadership of Lieutenant John R. Hamilton formerly an officer in the United States Navy and the son of a former governor of South Carolina. Built of pine heartwood logs sawn twelve inches (305 mm) square, it was buttressed by palmetto logs on the bow  and the exterior of the vessel was clad in two layers of railroad iron vertically and four layers of boiler iron horizontally. Its dimensions were approximately twenty-five feet wide by one hundred feet long. The massive front bow of the battery resembled a peaked barn to onlookers who branded it with that nickname. Along the barn face were four evenly-spaced casemate windows suitable for the naval guns to fire through. The battery's armament consisted of two 42 lb and two 32 lb naval artillery guns. A detailed drawing by a Confederate officer illustrates the guns (the fourth is not depicted). To offset the weight of the barn with the armament added, the vessel was counterbalanced at the rear with 6 ft. thick sandbag emplacements along the length of the stern. The powder magazines were below the sandbags while shot was stored behind the guns in covered bins beneath the deck. Positioned behind the stern and on its own separate raft was a small floating hospital.
  The March 30, 1861, issue of Frank Leslie's Illustrated Newspaper contains a detailed sketch of the hospital interior. There appears to be at least eight hospital beds and two operating tables. Access was gained by a steeply-angled staircase through a hatch in the roof. A framed wooden door allowed for entry and exit on the starboard side of the hospital closer to the waterline while two framed glass sash windows allowed in light on the port side. Window casements framed into the roof allowed for some additional light and ventilation.
