Lieut.-Commander Nasmith then chased and torpedoed a heavily laden store-ship, and drove another ashore, exchanging rifle fire with a party of horsemen on the cliff above. Altogether the day was a lively one, and the news, brought by Mr. Silas Q. Swing and his friends, shook Constantinople up severely. Mr. Einstein records that ‘the submarine came up at 20 minutes to 2 o’clock, about three hundred yards from where the American guardship _Scorpion_ lay moored, and was immediately fired at by the shore batteries. It shot off two torpedoes; the first missed a transport by about fifty yards, the second struck the _Stamboul_ fair, passing under a barge moored alongside, which blew up. The _Stamboul_ had a gap of twenty feet on her water-line but did not sink. She was promptly towed toward Beshiktash to lie on the bottom in shallow water. The submarine meanwhile, under a perfect hail of fire, which passed uncomfortably close to the _Scorpion_, dived and got away, steering up the Bosphorus. At Galata there was a panic, everyone closing their shops; the troops, who were already on two transports, were promptly disembarked, but later re-embarked, and still later landed once more. The total damage was inconsiderable, but the moral effect was very real.’ On the following day he adds, ‘S.’ (Swing, no doubt--Silas Q. Swing of the _Chicago Sun_) ‘came in with an exciting tale. On his way to the Dardanelles the steamer, which carried munitions and a 6-inch gun, had been torpedoed by an English submarine, the E. 11. They allowed the crew to leave, and then sank the ship. The English officer told him there were eleven submarines in the Marmora, and these are holding up all the ships going to the Dardanelles. They had sunk three transports full of troops, out of four which had been sunk, and various other vessels, but do not touch those carrying wounded.’ So, between Lieut. D’Oyly Hughes and Mr. Silas Q. Swing, the E. 11 became eleven submarines, and may go down the ages like the eleven thousand virgins of Cologne. Her commander evidently hoped to create a panic, and Mr. Einstein leaves us no doubt that the plan succeeded to the full. On May 27 he writes again: ‘The Marmora is practically closed by English submarines. Everyone asks where their depot is, and how they are refurnished.’ May 28: ‘The submarines in the Marmora have frightened the Turks, and all the remaining transports, save one, lie tranquilly in the Golden Horn. Otherwise I have never seen the port so empty. One wonders where the submarines have their base, and when and how it was prepared.’ He adds, with some shrewdness: ‘Probably, if at all, in some island of the Marmora, though the newer boats can stay out a long time.’ E. 11 was far from new, as we have seen, but she was in hands that could make her stand for quality as well as quantity.
