I was shadowing a convoy when all of a sudden I spotted a German submarine surfaced on the side of the convoy. He was in actually quite a good position to attack. All he did was stay there, stopped, while he got blasted by the British escorts. I got a grey sunken ship icon appear on my map where he was and all the escorts came back uninjured to their positions.
Why did the escorts attacked him and he didnt responded. It almost looked like the game told the submarine to stop and wait for the convoy to pass to avoid any collisions.
I was disapointed, I thought we were going to attack this convoy together.
That would have been cool.
