In the meantime Commander Boyle had been diving up and down all the morning between Fort Victoria and a point four miles up the coast to the east, about a mile from shore. Three times he came to the surface, but each time the troops turned out to be bullocks. At 1.30 P.M. (when he came up for the fourth time) more dust was coming down the road, and this time it was the right kind of dust. As he opened fire he heard E. 11 banging away. She had left the place where he had stationed her, to the N.E. of Dohan Aslan Bank, and had come down to join him in his billet. The two boats then conducted a joint action for the best part of an hour. Commander Boyle got off forty rounds, of which about six burst on the road among the troops, and one in a large building. But the distance was almost beyond his 6-pounder’s reach. He had to put the full range on the sights, and then aim at the top of the hill, so that his fire was less accurate than that of Commander Nasmith with his 12-pounder. E. 11 had strewed the road with a large number of dead and wounded, when guns on shore came into action and forced her to dive. She came up again an hour and a half later and dispersed the troops afresh, but once more had to dive for her life. Next day, Commander Boyle ordered E. 11 to change billets with him, and both boats had luck, Commander Boyle destroying a 5,000-ton supply steamer with torpedo and gunfire, and Commander Nasmith bagging a battle-ship. This last was the _Haireddin Barbarossa_. She was passing about five miles N.E. of Gallipoli, escorted by a destroyer. E. 11 was skilfully brought into position on her starboard beam, and the torpedo got home amidships. The _Barbarossa_ immediately took a list to starboard, altered course towards the shore, and opened a heavy fire on the submarine’s periscope. But she was mortally hit. Within twenty minutes a large flash burst from her fore part, and she rolled over and sank. To lose their last battleship, and so near home, was a severe blow for the Turks, and they made every effort to conceal the depressing details. Mr. Einstein, however, heard them and makes an interesting entry. ‘The _Barbarossa_ was sunk in the Marmora and not in the Dardanelles, as officially announced. She was convoying barges full of munitions and also two transports, when she found herself surrounded by six submarines.’ It is creditable to Commander Nasmith that he did so well with only six of his E. 11 flotilla. Einstein continues: ‘The transports were supposed to protect her, but the second torpedo proved effective and she sank in seven minutes. One of the transports and a gunboat were also sunk, the other ran aground. Of crews of 700, only one-third were saved.’ And on August 15 he records further successes by Commander Nasmith--a large collier, the _Ispahan_, sunk while unloading in the port of Haidar Pasha, the submarine creeping up under the lee of another boat; and two transports with supplies, the _Chios_ and the
