Well something that just hapened.
I was on patrol traveling to north atlantik and i was about to pass to west of england between the orkeneys and i dont remember the name but betwenn scapa flow and the other base on the northern islands of britain.
I got contact of slowmoving merchant and it turn out to be passanger/cargo around 2000 tons.Given the place in witch engagement was going to take place (so close to the bases) i (it was around 21 when i made visual contact) first tought of a silently torpedoing the ship and leaving but then the greed for not wasting Aals came.And given that it was deadcalm water i poped up 1,5 kilometers from the ship and shelled it.It took around 30 rounds and few minutes to sink.
With that hapening i continued my patrol and Oh surprise just few minutes after the sinking of the merchant a destroyer straith ahead at distance around 8-9 kilometers.Long story short - 1 hour of dodging depthcharging attacks i finally screwed and a DC hit pretty hard the forward torpedo area.
(something you should now is that sea floor was 79 meters so i didnt go below 65 because DC could miss me and explode on bottom)
Heavy flooding occured after the explosion of the DC and all tubes were destroyed.By the time the crew stoped the flooding there was so much water that the sub probably was 30 degrees pointing at the bottom and sinking.I could support it by using slow backwards but i have to stop machines in order not to surface.And so after another 10 min the destroeyer finaly hit me with dc and blew me to pieces :|
Imagine, and it was still '39
