Q-Ships?

[IceGrog]

On my way back to base on more than one occasion I’ve run into a single ship just sitting in the ocean not moving at all and with no apparent damage. (GW) why are these there, just curious? Now I just had the same thing happen but this time there were two ships sitting, the smaller (medium size) one was smoking, a larger cargo it’s friend was maybe a 100 yards away also just sitting there. I was surfaced because from my past experience these sitting ducks don’t fight back, I sent two torpedoes away, one for each. Two hits, but both stayed afloat, my crew had to load from externals so I decided to man the deck gun while I waited, I got a couple of shots off, (I was slowly getting closer) when the larger ship opened fire on me. I had to dive because the shots were getting really heavy. I told my boat out beyond their range and surfaced while I finished loading. I went back and sunk them both; these two ships were in the same location?
