Longyearby is a nasty place. Went up there late March 1940 killing time for the Narvik action. Sailed right in cos Norway was neutral and sussed the place out. There was a small passenger liner or troop ship and a tanker i think or possibly a large merchant. Seemed like a possible fall back so I decided to do Narvik and return. Sorry I ever did. I think it was the longest patrol ever. Ran in submerged with loads of warship contacts everywhere. Sank one of the biggies but the escorts were all over the place. Grey sunken ship logos everywhere! They were running into piers and grounding themselves everywhere but there were still s***loads of them. Nothing bigger than a frigate and tons of trawlers and elco boats. Just enough to make you keep your head down. The crew were blue in the face by the time I got out. 2 whole evenings for 10000 tons. Not worth it
