From the Logbook
The first ironclad battle
On 9 March 1862 she fought CSS Virginia at Hampton Roads, the first engagement between ironclad warships.
A cheesebox on a raft
Contemporaries described her that way. The low freeboard and revolving turret that made her formidable in sheltered water are what sank her at sea.
The first National Marine Sanctuary
The water above her was designated in 1975 specifically to protect the wreck — the first such designation in the United States.
