"The destruction of the enemy's means of transport in the Sea of Marmora has been pursued throughout with the utmost regard for humanity. Ships carrying refugees have invariably been spared, and the crews of sailing vessels either given time to escape or rescued at considerable inconvenience to the submarine. On many occasions the crews of vessels destroyed have shown their surprise and gratitude at the consideration shown to them." The first boat to enter the Narrows was "B 11" (Lieutenant Holbrook). She successfully torpedoed and sank the Turkish battleship _Messudiyeh_. The outstanding fact of this feat was that the boat was built in the summer of 1906, making her well over eight years old when she went into the Dardanelles. Eight years is a great age for a submarine in a Service which advances every month in the knowledge of construction, and "B 11" was in 1914 almost ready for a final paying off. She showed, however, that the old boats were by no means useless if handled as they should be. The first trip right into the Marmora was by "A-E 2" (Lieut.-Commander Stoker). She was an Australian boat of the same type as the other E's. She was unfortunately sunk by a destroyer in the Marmora after getting in.[4] [4] As I have not the despatch by me, I am postponing the account of her passage till later. In the Baltic also, at the beginning of the war, targets were far more plentiful than in the North Sea. Commander Horton in "E 9" sank a destroyer on January 29, 1915. On June 4 he sank a transport which was protected by a destroyer screen. On July 2 he torpedoed and badly damaged the _Prinz Adalbert_. On July 29 "E 1" (Commander Laurence) sank a transport. On August 19 he torpedoed and damaged the _Moltke_, incidentally causing the enemy to withdraw from the attack on the Gulf of Riga--an attack which at the moment showed every probability of succeeding. Later in the war the Germans renewed their attack successfully--secure in the knowledge that the internal conditions caused by the Revolution had prevented the British submarines from operating. At that time we had in the Baltic four "E" Class ("E 18," Lieut.-Commander Halahan, having been lost at sea in May 1916 with all hands, from a cause unknown) and four "C" Class. The latter boats had, instead of entering the Baltic by the Sound, come in August 1916 _viâ_ the White Sea and up the Dvina river in wooden barges towed by tugs; they came practically empty, and their batteries, etc., were replaced in them on arrival at Petrograd. The Revolution caused such chaos that the flotilla was practically tied to harbour after the Soviet Government's installation. "C 27" (Lieutenant Sealy), however, was able to torpedo a transport during the attack on Oesel, and was also reported to have damaged one of the screening vessels. There is no doubt that the knowledge that these submarines had been rendered powerless enormously helped the Germans in the Baltic.
