Well, I resurrected good ol' Fritz and his skeleton crew to try out NYGM again. Same patrol really, DH19, a 10 day cruiser at Ahead Slow from Brest.
This time I tried out three watch shifts and two of everyone else. Seemed to work pretty well for mangement swaping everyone out at 0800, 1600 and 0000.
I got to the patrol area and finally got a radio contact about a convoy north of me, heading ESE. Did some plots, figured out that at Ahead Standard I'd meet up with them around 9pm. That was good. (Now, turns out I miscalculated horribly, it wasn't 9pm it was 1900!! So i bumped into them during daylight, but it was foggy and stormy so I wasn't too worried.
I plotted a parallel course to the convoy and started to swap people around since I'd missed their 1600 crew change. As I'm doing this someone screams "We're under attack!!" So I crash dive, turn away and hope for the best.
10-15 minutes later they are pining me, depth charges are above me, so I think I'm ok. Drop to 100m and keep going on silent run. Pinging me again, I drop deeper (really should have just plummeted from the start) and turn south.
Depth charges but I'm not worried since they'd been off before, and I'm lower and heading even deeper now. WRONG! From inside the control room I see the boat start to shudder. Damage reports flood in! Torpedo tubes damaged, something else damaged, stern quarters are flooding!
So I move my chief engineer, who is repair certified, and a full crew of rested petty officers into stern quarters since I know NYGM does repairs based on where the damage it. The little flooding icon reads 1:15 and is getting lower. I dump the rest of my off shift crew into the damage control area up top, and give them a watchman. I click on stern quarters, but there's nothing to repair?
So I have a full set of rested people led by a repair officer IN the flooded compartment, I have a full set of rested people and an officer in damage control, but there's no listed damage to fix and the flooding NEVER stops. One minute real time later I'm dead. What happened?
I forgot to turn OFF Silent Running.

Hehe
"Oops, my bad!" - Bernard.
So tonite's lessens are... Pay more attention to silent running. Plot more carefully. Don't put Bernard in charge of repairs.

Oh well, I have a save from before I met the convoy, so tomorrow we'll try things a little differently.
