Or you can remove the subnet cutter off the front of your VIIB and systematically use it to saw the boat into pile of timber wood, then rebuild it into a Giant wooden Uboat sculpture to demorilise the British, just make sure you do it at night though, or you might get caught by the police.
Then you could go up to Gunther Prien and say "Scapa flow?, PAH! geuss what we did last patrol! NAH NAHHH NAHHHHH NA NAAAAAAAAAAAAAAAAAAAAHHH"
