Well, after my first brilliant attack mentioned above, i wizzed ahead of the convoy got into position again and got another Grosse Ladung, Liberty and a Grosse Frachter. I sneaked off out the back of the convoy and just when i thought i'd made it I got picked up by the rearguard.
This time they really have me pinned. I got hit once and am presently at 250m and trying to throw off at least 2 DDs. Tried 2 bold maneuvers but it's no good.
Once there's two of them on you...
It's going to be a long trying time before i'm lucky enough to throw them both off. If, that is.
