Fate:
Supported the British surface fleet at the 'Battle of Helgoland'.

Carried out two patrols in the Marmara.   While proceeding up the Narrows by Nagara Point, the submarine became entangled in a net and could not break free.   The commotion on the surface caused by Cochrane's manoeuvring of his submarine did not go unnoticed.

A spectator of events was Oberleutnant zur See Heino von Heimburg, commanding officer of a German U-boat under repair at Chanak.   Heimburg himself visited the spot in a small skiff (rowed by his cook) and lowered a small explosive charge over the side.   When he made contact with what he hoped was a submarine, he fired the charge and was rewarded with the sight of E.7 coming to the surface.

Cochrane and his crew became prisoners of war (although Cochrane escaped in 1918) and Heimburg dined out on the story for the rest of his life.

Sunk by UB14 in the Dardanelles, 4th September 1915.
