Yah
Well there I was, coolly cruising around on the U.S. Eastern Seaboard looking for targets, when out of the mist comes a lone DD forcing me to dive sharpish! Now I don't know what his problem was, an ace complex or what, but he just couldn't let me go no matter what

I finally slipped away after 3 hours of frantic manouvering combined with making like a very small and quiet hole in the water...
Fortunately, what one can do with a VIIC is to go deep... and then a bit deeper just to make sure. Yah, was what saved my butt in the end
