Another person wrote some information that I have seen in several places concerning the CSS Arctic.
Flt. Btry: 3 guns (Floating battery)
Built in Wilmington 1863, as ironclad floating battery and additional duty as a receiving ship for Flag Officer Robert F. Pinckney's Naval Forces Station Cape Fear River from 1862-1864 with Lt. C.B. Poindexter, CSN, in command.
Her machinery removed in the latter part of 1862 for ironclad CSS Richmond then completing in Richmond.
With threat of First Attack on Fort Fisher, it was sunk 24 December 1864 to obstruct the Cape Fear River channel.
Another person commented that the Arctic's engine was removed in 1859 and was providing power to a sawmill when the CSS Richmond was commissioned with engines built by Naval Ironworks in Richmond, Virginia.
