Did a patrol in BE2-BE5. Chased down multiple freighters mostly neutral countries and I couldn't find evidence for sinking them. Only found one that was going to Liverpool and one actual target. Found a couple solo targets but was burning up fuel chasing them down.
One the way back to Brest I found a convoy and nipped at it a few times bagging 5 of them in total from that convoy.
Next assignment was to go to, I think, Bear Island and set up a weather station. Uneventful there but on the way back I did hug the English coast and maul a couple small convoys Had another crewman go down with TB on this one. I also stress tested them again and found another 4 seawolves and 6 cowards. Got back to Brest, gave the crew a rest and installed a snorkel in late summer 1940. Put the specialization points on my seawolves so I should be a bit quieter and dive quicker.
By the time the crew got back it's now September 1940 so that's one year down. I checked and I can upgrade to the VIIC/41, I think I'll wait until at least 1941 before I do that.
I sent the rescued officer to the naval academy because I didn't know what it did. Turns out it's a waste to do that as you can't put him in your crew. What it does do is sends an officer away for 16 days and they get 2500xp out of it. So you could use that as a way to train replacement officers at the cost of requisition points. Might come in handy in future playthroughs staying more historically accurate to not get too far ahead in research and maybe release salty officers so they can go crew their own boats.
