The CSS VirginiaII, was one of four casemated ironclads built at Richmond after the loss of the CSS Virginia (Merrimac). These ironclads mostly patrolled the James River above the Confederate and Union obstructions, but were involved late in the war in an abortive attempt to break out and attack the Union supply base at City Point, VA. All the James River ironclads were blown up upon the fall of Richmond, 4 Apr 1865.
