Thank you for sharing this!!
Every time i read one of these stories, my mind always tries to visually see these young men and the very frightful death they met with.
It's always very sobering.
As much as i love submarines and the idea of sailing beneath the waves, the horrors associated with the history of the submarine are always present in my mind.
I suppose the same can be said of any amazing product of engineering like airplanes or rockets or tracked vehicles etc etc
