Was transiting the Orkney Shetland gap when I ran into this fella.
Hit him with 1 torpedo (out of 2 fired), then finished him off with the deck gun. The weather was bloody atrocious.
EDIT: It was darker in game. I lightened these so you could see 'em better!
EDIT AGAIN: Just realised, worryingly the deck gun crew were quite happy to man the gun in this rough weather, and no-one was wearing any wet weather gear.
Has anyone actually seen wet weather gear in this game yet?
