On the night of December 30-31, 1862, the USS Monitor, caught in rough seas as it made its way past Cape Hatteras, North Carolina, sank. Sixteen crew members perished.
Many years later efforts were made to raise the Monitor, with recovered pieces being sent to the Mariners’ Museum in Newport News, Virginia. You can listen to a presentation about the conservation of the wreck here:
