Hello fellow submariners,I've played SHIII vanilla for a while,now thanks to this forum It's now GWX3.0 for me

I have been reading all I can,when I can,but I still come up with the odd question once in a while.
I started over again,now I'm on my third patrol and have read the gwx manual,for the most part.It says the ships Gneisenau and Scharnhorst are scripted in the game.Operation Berlin has started,I am near their actual routes taken.Will I find them+should I help them?I'm almost sure but not 100%.Thank you for your help.I'm sure I'll have more Q's in the future.
