Ouch, bad luck... sinking more than 30k grt in a single convoy attack at the end of 1942 was a big achievement but you paid it the hardest price... We'll remember your boat and crew.
But flat seas are not our friends as they make detection way too easy for escorts and once they start to pound you with depth charges or worse, hedgehogs... well, you know the story. I never attack convoys in flat seas past 1941, luckily weather is bad most of the time in my patrols!
