Previously recorded fate
Depth charged on July 27, 1918 by the RN trawler Calvis and yacht Vanessa II at position 5423N, 0024W. In fact, UB 107 probably was not present for this attack.

UB 107 was, however, the only U-boat that could have been responsible for the sinking of the steamers Chloris and John Rettig two and a half hours later at position 5352N, 0010E. Divers in recent years discovered the wreck of UB 107, which was identified by markings on the propellers, off Flamborough Head together with (under) what remains of the steamer Malvina. The Malvina was torpedoed and sunk by UB 104 on August 3, 1918. UB 107 apparently either suffered an accident of some sort or was lost on a British mine.
