History and life are not always the same as the romantic idea we sometimes have of them; nevertheless knowing the truth doesn't hurt and doesn't also mean you can't keep a romantic idea where appropiate. it's just that things are not always in all of their parts what you thought of them.

official source) that will tear down a good amount of romanticism, follow the link I posted below:
BUT WARNING: Those who want to keep the "Das Boot" image of the real crews, DON'T READ IT
