Well, wow...I escaped!!!!!
At about 8 pm I rose from the bottom, still being pinged by both destroyers but they had not thrown charges for hours so both were out. Rose to periscope depth but they were still so close to me that risking surfacing would have been certain death. I plotted a course to the small island group in BF24 hpoint to reach that and maybe ground the destroyers. But in reality it would have too far away. At about 11 pm a corvette joined the party so I was up against 3 foes again, one some depth charging started once again, none hit.
I just kept my course but at around 3 AM suddenly the pinging stopped...I stayed as deep as possible at 1 knot for another hour and then rose to persiscope depth again. They were gone, I still heard and detected a flower class to my starboard side at bout 13 km's away.
So I am now on the surface at full speed while charging my batteries and restoring oxygen and compressed air.
All in all about 17 (game-) hours of cat and mice...but I survived!
