The H.L. Hunley made history back in 1864 when it became the first submarine to successfully attack an enemy ship. Launched by the Confederacy as a way to break the Union blockade of Southern ports during the Civil War, it sank the USS Housatonic on 17 February 1864 and itself mysteriously sank shortly thereafter.

Crew members hand cranked the propeller to make the sub move forward and its one weapon was a bomb set at the end of a long pole. The idea was to ram a ship with the bomb, which would then explode and leave a hole below the waterline. That's what happened when the H.L. Hunley attacked one of the warships blockading Charleston harbor, but the sub never returned from its mission.

The Hunley was later found and brought to the surface. Now after several years of restoration the Confederate submarine has been placed upright for the first time since its sinking. The sub had been found resting at a 45 degree angle in a layer of silt and was kept in the same position until now. Moving it to the upright position has given researchers a look at a side of the ship unseen since 1864.

The researchers have found some holes on that side but are unsure if they are natural erosion or the cause of the Hunley's sinking. Analysis of the bones of the eight crew members showed they died of a lack of oxygen. Interestingly, they were all at their posts as if nothing was going wrong.

You can visit the lab where this historic sub is being studied. The Warren Lasch Conservation Center is located in North Charleston, SC. You can also see a different Confederate submarine at the Louisiana State Museum in Baton Rouge.
