Well, 7 hours and I was complaining about 3!
But, the only times I have escaped from 2 plus hours of multiple escorts was, believe it or not, coming to periscope depth and sneaking away.
I had given up and decided to fight with my last fish but as I snuck away to make a stern shot they did not follow.
Maybe a one time deal????
I had edited all my escorts to be 3 or 4 from the start but frankly the improved equipment in 43 then 44 makes the 4s impossible if there are 2 of them or more.
So I since have edited convoys to only have one 4.
I still have not survived what you have and I am sure I stand in a long line of the impressed!!!
Can't wait to hear the verdict like a Kaleum listening to reports in an area too far away to do anything but hope you survive.
