They came. After one minute he observed a very vivid flash on the water-line at the point of aim. This was immediately followed by a very heavy concussion, and the entire ship was hidden instantly in a huge column of thick grey smoke. Evidently the torpedo had exploded the fore magazine. The sky was filled with debris, and the smaller bits began falling in the water near the submarine. There was no use in spending time on the surface, and in one minute more, E. 8 was sliding down to fifty feet, where she stayed for eight minutes, to give the rest of the ship ample time to come down. At 9.42 Commander Goodhart rose to twenty feet, and took a survey through his periscope. There was no sign of the _Prinz Adalbert_. The two destroyers had closed on to the scene of the explosion, but it was not likely that they had been able to find any survivors, for the destruction of the ship had been instantaneous and complete. Commander Goodhart decided not to attack them, because, for all he knew, they were ignorant of his presence; if so, they might very probably imagine the damage to have been done by a mine, and give him future opportunities. The shot had been a long one, about 1,300 yards, and this was in the circumstances particularly fortunate; for at a shorter distance, such as 500 or 600 yards, the submarine herself would have felt a tremendous shock from the double explosion. An hour later he saw four destroyers hovering about the place of the wreck. He turned away, and they made no attempt to follow. At dawn next day he reported by wireless, and then proceeded to his base. In the meantime E. 19, Lieut.-Commander F. N. Cromie, had arrived. She set to work in earnest upon the German shipping engaged in the service of the naval and military departments of the enemy, towards the western end of the Baltic. Monday, October 11, was her best day, and the beginning of a downright panic in the Hamburg trade. ‘8.0 A.M.,’ says Lieut.-Commander Cromie, ‘started to chase merchant shipping.’ He had good hunting. At 9.40 A.M. he stopped the _Walter Leonhardt_, from Lulea to Hamburg, with iron ore. The crew abandoned ship, and were picked up by a Swedish steamer, considerately stopped for the purpose. A gun-cotton charge then sent the empty vessel to the bottom. By noon, E. 19 was chasing the _Germania_ of Hamburg, signalling her to stop immediately. In spite of the signals and a warning gun-shot, she continued to bolt, and soon ran ashore. Lieut.-Commander Cromie went alongside cautiously to save her crew, but found that they had already abandoned ship. He tried to tow her off, but failed to move her--small wonder, for her cargo consisted of nearly three million kgs. of the finest concentrated iron ore, from Stockholm to Stettin. He left her filling with water, and at 2.0 gave chase to the _Gutrune_. By 3.0 he had towed her crew to the Swedish steamer, and started her for the bottom with her 4,500,000 kgs. of iron ore, from Lulea to Hamburg.
