A British ship sunk under its own flag, John Bull, personification of Great Britain, calls for a false flag with which to disguise his ships even as he is being dragged beneath the surface by German mermen — submariners with armbands in the colors of the German flag. Personifications of neutral nations holding their flags include Uncle Sam of the USA, a Nederlander, and representatives of Sweden, Norway, and Denmark. In the distance, the British Isles have been hit, bombed by a Zeppelin or shelled by a sea battery.

". . . the logs and code-books recovered from the captured Turquoise provided the German and Ottoman navies with details of the rendezvous locations and of the times of meeting with the other British submarines. On 5 November, Oberleutnant zur See Hugo von Heimburg, commanding UB14, set out from Constantinople to one of the rendezvous positions and at 4 p.m. sighted a conning tower, 5 miles to the north. At 5.10 p.m., and at a distance of 550 yards, he fired one torpedo which hit and sank E20. . . . At 5.20, UB14 surfaced and rescued two officers, including Warren, and six sailors from E20's crew."
During the Allied Gallipoi campaign, French and British submarines made the hazardous journey through the Dardanelles to attack Turkish shipping in the Sea of Marmara. On October 20, 1915, the French submarine Turquoise made its way through the Dardanelles. The ship was plagued with problems that included electric motors that caused short circuits and fires, a leaking periscope, a malfunctioning gyrocompass, and faulty forward hydroplanes. Returning through the Dardanelles on October 30, it surfaced, was seen and fired on by shore batteries, dove, struck bottom, resurfaced, and surrendered. Turquoise was taken with its logs and code-books. Using these windfall, UB14 set out to a rendezvous point, and found the British submarine E20 under Lieutenant Commander C. H. Warren.
