On Feb 17, 1864, a H.L. Hunley, a 40-foot-long Confederate submarine, sank to a bottom of a sea off Charleston, South Carolina. The reason because is still a mystery.
That day, a Hunley became a initial submarine to penetrate an rivalry boat during conflict when it embedded a shoot in a USS Housatonic’s hull. After a shoot detonated and sank a ship, a underling signaled to seaside that a goal had been finished and started streamer behind to land…but it and a 8 organisation members aboard never returned. The underling sank to a sea floor.
After some-more than 150 years, nobody can contend for certain what accurately happened to a men. One thing’s for sure, yet — something killed them all unexpected and left no earthy injuries.
After a underling was lifted from a sea in 2000, a carcass wasn’t found to be majorly damaged.
Even when researchers unblocked a organisation compartment, they still couldn’t find a clear means of death.
