CSS Albemarle was one of three ironclads laid down in early 1863 to combat control of the North Carolina sounds. Only the ram Albemarle would become operational and able to contest Union control of eastern North Carolina until its dramatic sinking in October 1864.
A 19-year-old boatbuilder, Gilbert Elliot of Elizabeth City, North Carolina, sent a proposal to Confederate Secretary of the Navy Stephen Russell Mallory. His idea: to construct ironclads up the various rivers that were out of reach of Union forces. Mallory agreed. So, Elliot submitted sketches to Confederate Naval Constructor John L. Porter, who established working drawings.
