I have been writing about J.J. Ingraham who at least at times was stationed as a boatswain on the CSS Arctic. There is not a lot written about the CSS Arctic at the Wilmington (N.C.) Naval Station in the Cape Fear River.
Civil War Talk had a thread running on it at one time "CSS Arctic--what do we know?" Not much.
A person wrote that he knew it was a floating battery with a "nifty" name, but that was about it.
Another commented that it was a receiving ship and at one time 38 Confederate Marines were stationed there after the loss of their ship, the CSS Raleigh.
Wikipedia lists it as an ironclad floating battery, burned in 1865, but had no article on it.
