The one great day of his nine days’ patrol was June 25, when he brought off a hand-to-hand fight on the surface with three enemy ships. At 10.45 in the morning he sighted, in the Gulf of Mudania, a small two-decked passenger steamer. ‘She looked,’ he says, ‘rather like a tram-car, and was towing two sailing-vessels. In the distance was a sister of hers, towing three more.’ He chased, and soon stopped the nearer steamer. He could see, as he steamed round her, that she was carrying a lot of stores. She had no boat, and all the crew appeared to be on deck in lifebelts. He could see no sign of guns, so he ran his bow up alongside and sent his first-lieutenant, Tristram Fox, to board her. But guns are not the only risk a submarine has to take on such occasions. As the boarding party stepped on board the steamer, a Turk heaved a bomb over the side. It hit E. 12 forward, but did not explode, and no second one followed. The Turks, however, meant fighting, and they opened fire with rifles and a small gun, concealed somewhere aft. The situation was a very anxious one, especially for Lieutenant Fox and his boarding party; for they knew their own ship must open fire in return, and it was difficult to take cover on an enemy ship in action. Lieut.-Commander Bruce was in a very tight corner, but he kept his head and played his game without a mistake. He did not hesitate to open fire with his 6-pounder, but he began upon the enemy’s stern, where the gun was concealed, and having dealt with that he turned to her other end and put ten shots into her from fore to aft. His men shot steadily, though under gun and rifle fire at a range of only ten yards, and his coxswain, Charles Case, who was with him in the conning-tower, passed up the ammunition. Spare men, with rifles, kept the Turks’ heads down, and all seemed to be going well, when the two sailing-ships in tow began a new and very plucky move of their own. They came in to foul the submarine’s propellers, and at the same time opened fire with rifles, taking E. 12 in flank. But by this time the steamer was beaten, and the British rifles soon silenced those in the sailing-ships. Then, as soon as Lieut.-Commander Bruce had cleared the steamer, he sank the three of them. The steamer had probably been carrying ammunition as well as stores, for one of the shots from the 6-pounder touched off something explosive in her forward part. In fifteen minutes she was at the bottom.
