Shot at Dawn?

April 1943, torpedoed a hospital ship in error but finished the patrol with two other ships totalling 13,700 GRT not counting the big white thing with the red crosses on it (at least I assume it was big and white and red all over, never got a good look at it in the filthy weather conditions at the time of the attack. No excuse I know).

Got back safely to the St. Nazaire bunkers on the 26th of the month ok but showed up dead on arrival. The SH3 Commander profile has the boat, U-581, intact (well damaged but 94% H.I. remaining) and the crew in good health with only the captain dead. Incurred a renown penalty of -7553.45 but didn't expect it to be fatal. The only thing I can figure is GWX had me shot at dawn pour encourager les autres.

DiD, no problems if that's the case, just wondering if this is what happened so any insights are welcome. Thanks.

In any event I think I will cross hospital ships off my hit list in the future so as to avoid lead poisoning.
