Merrimack was the first of six screw frigates (steam frigates powered by screw propellers) begun in 1854. The CSS Virginia then took part in the Battle of Hampton Roads (also known as "the Battle of the Monitor and the Merrimack") in the first engagement between ironclad warships. USS Merrimack, also improperly Merrimac, was a steam frigate, best known as the hull upon which the ironclad warship CSS Virginia was constructed during the American Civil War.

Historical Records: Some historical evidence suggests the Hunley did not sink immediately after the attack and light, perhaps in the forms of signals, was seen by both Union and Confederate sources. These small glass ports were equipped with iron covers that could make the ports watertight and also block any light from escaping the sub, and possibly alerting ships to their presence.

The submarine had a series of 10 topside ports that provided the crew a small measure of ambient light when the Hunley cruised on the surface. This discovery suggests the crew may not have drowned, but died of some other cause.īlackout Mode: The Hunley was in Blackout Mode when she was lost. Those settings could reveal what steps – if any – the crew may have taken to try and save their lives.Ī preliminary study of pump system shows that it was not set to pump water out of the crew compartment. The pumps are still in the same position they were on the night the submarine was lost. If the crew had been desperately trying to escape, it is reasonable to assume both hatches would have been unlatched.īallast Pump Settings: When the Hunley mysteriously vanished, most students of history assumed the eight-man crew drowned. This could be significant, but the hatch was heavy enough that it would stay sealed while the submarine was underwater and upright. Scientists found one hatch was locked and the other was not. The forward conning tower was found unlatched. Hatches: The hatches that sat on top of the forward and aft conning towers served as the only access points into and out of the submarine.
