CSS Charleston

CSS Charleston was a casemate ironclad ram built for the Confederate Navy (CSN) at Charleston, South Carolina during the American Civil War. Funded by the State of South Carolina as well as donations by patriotic women's associations in the city, she was turned over to the Confederate Navy and defended the city until advancing Union troops that threatened Charleston caused her to be destroyed in early 1865 lest she be captured. Her wreck was salvaged after the war and the remains have been obliterated by subsequent dredging.

Construction and description
James M. Eason was awarded a contract by the State of South Carolina to build a larger ironclad at Charleston in November 1862 after he finished the casemate ram CSS Chicora. Funds were also contributed by the city's "Ladies' Gun-boat Association", which led to Charleston's nickname of the "Ladies' Gunboat". He began construction the next month and completed the ship in September 1863.

Charleston was 189 ft long overall and had a beam of 34 ft. Her depth of hold was 14 ft and she had a draft 12 ft. The ship had a displacement of 600 LT. Charleston's propulsion system is unknown, but her engine had a diameter of 36 in and her propeller was 8 ft in diameter. At any rate, she was credited with a speed of 6 kn. The ship was armed with two 9 in smoothbore guns at the ends of the ship, probably Dahlgren guns, and four muzzle-loading Brooke rifles on the broadside that fired 90 - 110 lb projectiles, which would make them 7 in guns although their exact type is unknown. Charleston was also fitted with a wrought-iron ram. The ship's armor was 4 in thick. All together, her ram and armor weighed 600 LT. Her crew numbered 150 officers and enlisted men.

Service
Once completed, Charleston served as the flagship of the CSN's Charleston Squadron together with the rams CSS Palmetto State and Chicora. Her only captain was Commander Isaac N. Brown. The ship was set on fire and blown up with 10 LT of gunpowder in the Cooper River on the night of 17/18 February 1865 to prevent her capture by the Union Army once the city was evacuated by the Confederates. The wreck was salvaged to a depth of 12 ft below low water by Benjamin Maillefort in 1872–73 and the site has been thoroughly dredged to deepen the channel, destroying any remains. Its last known location was at 32.79139°N, -79.9225°W
