Enemy T Class Submarine.

[RustySubmarine]

I encountered a stationary T Class Submarine in Loch Ewe, so decided to see if I could target it. I sent one torpedo from approx. 1800 yards and scored a hit. I then fired at a small tanker with tube 2 and also scored a hit. Then I decided to get the hell out of it, as quite a few searchlights came on and a couple of destroyers appeared on the scene. I managed to get to the open sea on silent running until the coast was clear, so I could surface and head off into the North sea. My Captains log showed that I had sunk the T Class sub & the small tanker. However on the chart there was only one sunk ship icon for the tanker, the submarine although sunk too, was not showing on the chart. Is this normal for submarines, not to display a sunk icon on the map, even though it is actually recorded in the captains log as sunk.
