Oh yes, that wasn't a lot of fun,
despite that little setback I managed to sink 78k GRT that patrol and make it to Bordeaux in one piece -ish.
But I had to leave real quickly again because the Allies were approaching with tanks and stuff it being august of 1944
Next time I won't take pattern runners at all, too much hassle
I made it through Biscay Bay again thanks to the weather and am now west of Ireland having just dodged a Hunter Killer group with 2 escort carriers.
I figure about 100km behind a Hunter/killer group is a good place to be for a Uboat
