Yes I know, this is a machine of war used by racist haters. That aside, it's a really neat project on a legendary submarine long lost. There is at least one more Confederate submarine somewhere in Lake Ponchatrain.
More CSS Hunley. I always wondered where it was. Too bad they didn't find it earlier. Remarkable project.
USS Monitor. Another famous ship, now found and mostly lifted from the bottom.
Account of the battle of the Merrimac attacking ships in Hampton Roads, Virginia.
