The Vessel and Her Loss
Launched in 1900 for the Cromwell Line's New York-New Orleans passenger and freight service, Proteus was considered a modern and well-appointed vessel. On August 19, 1918, sailing under wartime blackout conditions in dense fog, she was struck by the tanker SS Cushing off North Carolina and sank about six hours later with the loss of one crewman. The Navy later dynamited the wreck as a hazard to navigation, and it remains a popular deep dive off Ocracoke.
