"E 7" (Commander Cochrane) made herself unpopular with the enemy in July of 1915. She passed up the Dardanelles (being missed "overhead" by a torpedo fired from Kelid Bahr) on the 30th June, and on 2nd July sank a steamer and two dhows in Rodosto Bay. On the 3rd she sank a brigantine, and on the 6th a 200-ton Zebec and another brigantine. On the 7th she got a tug and a ferry-steamer and had an action on the surface with a two- or three-gun gunboat which retired, leaving a dhow to its fate. In the evening she chased a ferry-steamer ashore. In the morning she sighted the same ferry-steamer under way and sank her. On the 9th she got a Zebec, and on the 10th she dived into Mudania and torpedoed a steamer alongside the pier. On the 11th she sank two dhows, and on the 15th she dived into Constantinople and fired a torpedo at the Arsenal (which is close to the water) in the hope of detonating something. The explosion was very heavy when the torpedo hit. She then dived out and came to the surface off Zeitunlik Powder Mills, into which she fired twelve rounds. On the 16th she sank a dhow, and at 9.30 A.M. on the 17th she opened fire on a railway cutting a mile west of Kaya Burnu and blocked the line. She then waited till she saw a heavy troop train going west, and chased at full speed to pick up the fruits of her labours. The train entered the cutting, and, as was expected, backed out again into Yarandje Station. "E 7" settled down to work, and after twenty rounds had been fired, three ammunition cars blew up. Later in the day she shelled another train and hit several cars, without, however, doing so much damage. She concluded an interesting day by sinking another dhow. On the 18th she sank a brigantine, and was fired at by rifles from Mudania. She replied by hitting a steamer with one shell, and the buildings from which rifles were being fired with ten. Three shells fired into a small shed on the beach produced heavy and satisfactory explosions. On the 19th she sank four sail, and on the 21st one; on the 22nd she fired again on a train rounding Kaya Burnu and on a stone railway bridge. On the 24th she came back through the Narrows, presumably to the immense relief of the Turks. On her next trip, as has already been related, "E 7" was sunk and the crew captured. The coxswain was imprisoned some 60 miles from the coast of Asia Minor. He made a small canvas boat, _carried it with him_ to the beach across that 60 miles of hills and put to sea. He was blown back by a gale, however, and recaptured on the day that his captain escaped from a camp 300 miles inland.
