Also irrelevantly, and probably not so true of modern submarines, a former colleague took the surrender of a submarine of the Kriegsmarine during WW2. The captain, apparently a fanatical Nazi, hadn’t wanted to surrender, so the crew shot him.
My former colleague descended into the submarine and, he said, the smell of Sauerkraut and Diesel oil made him feel immediately sick. He said that he completely sympathised with the crew wanting out.
It’s an aspect of submarines we tend not to think of, because of course film doesn’t reproduce smells.
