5 ships sunk (10,706 tons) and 1 ship damaged (11,500 tons).

We have a picture of this vessel.
(d.) means the ship was damaged.
[Mine] indicates the vessel was hit by a mine laid by said U-boat.

In some cases the exact positions of losses are not known, those are not shown.
In other cases the posititions are too close and the markers overlap, not much we can do about that.
