Immediately after 'Commissioning' Submarine E20 was sent to the Mediterranean to bolster Submarine Operations at the Dardanelles.

E20 entered the Sea of Marmora and was programmed to rendezvous with the French submarine Turquoise on 6th November 1915 to co-ordinate plans. Unfortunately the details of the rendezvous position (40º45'N 28º10'E) were captured by the Turks after the Turquoise had run aground and was abandoned by its Officers and Crew.

The position and time of the rendezvous was passed to the Commanding Officer of the German U-Boat UB-14 (Lieutenant von Heimburg). Whilst E20 was waiting on the surface at the rendezvous point the submarine was torpedoed by UB-14.

The following personnel made up the crew of E20. Of these ten survived to be taken Prisoner of War (one died whilst still a Prisoner) & twenty one were lost in the sinking. Those who died are listed above.

06-11-1915 : On 30th October 1915 the French submarine Turquoise ran aground near Nagara Point, in the Dardanelles. With the submarine directly under the Turkish shore batteries the French crew hastily abandoned ship. Unfortunately for E20, who was due to rendezvous with the Turquoise, the French Captain had failed to destroy his confidential papers. The Germans now knew of the rendezvous and dispatched U14 to intercept the unsuspecting E20

U14 first sighted E20 at 1600 and at 1700 at a range of 550 yards she fired a single torpedo scoring a direct hit.
08-02-1917 : Able Seaman Arthur James Howard died (illness) in the POW Camp at Angora
