Steven Schwankert and the HMS Poseidon
on October 11, 2013
When the HMS Poseidon struck a Chinese freighter in the Gulf of Bohai in 1931, the collision sparked a devastating accident that would see the British submarine plunge to the ocean floor in mere minutes, claiming the lives of nearly half the crew, but then making history through the daring escape of six submariners who found themselves trapped in the torpedo room of the doomed vessel and made their way to the surface nearly an hour after its sinking.
