We have a picture of this vessel.

(t.) means the ship was a total loss (included in ships & tonnage lost).

Below is a map showing the locations of the attack(s) in question:

ship sunk or total loss (9). ship damaged (5).

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.
