Lieut.-Commander Cromie continued to have the good fortune he deserved. He ended the 1915 campaign with another war-ship in his bag. Cruising in the Western Baltic on the morning of November 7, he sighted a light cruiser and two destroyers, but was disappointed in his attempt to attack. Three hours later, at 1.20, in a favourable mist, he had a second chance. A light cruiser--perhaps the same--with one destroyer in attendance, came on at fifteen knots, steaming south and east. He dived at once, and at 1.45 fired his starboard torpedo. The range was about 1,100 yards, and the shot went home on the cruiser’s starboard side forward. She immediately swung round in a large circle and then stopped dead. She appeared to be on fire and sinking. But Lieut.-Commander Cromie was unwilling to leave her in uncertainty. He avoided the destroyer, passed under her stern, and manœuvred for a second shot. This was fired at 1,200 yards, and was aimed at the cruiser’s main-mast, just abaft of which it actually struck. A double explosion followed. Evidently the after magazine had blown up, and several large smoking masses were shot out some 200 yards in the direction of the submarine. The destroyer then opened a heavy fire on the periscope with H.E. shell. Down went E. 19 for her life; but three minutes later, she was up again to see what was happening. The cruiser--she was the _Undine_ of 2,650 tons--was gone. The destroyer was picking up a few survivors, and after a restless half-hour made off to the southward, leaving on the scene only a ferry-boat flying the German mercantile flag. Lieut.-Commander Cromie left also, and arrived next day at Reval, where he reported the attack and added that, under existing weather conditions, it was only rendered possible by the sound judgment and prompt action of Lieutenant G. Sharp, who was officer of the watch at the time. E. 19 was not alone in her successful campaign against the German iron-ore trade. A week after her fine break recorded above, E. 9 arrived on the scene; and Commander Max Horton, in two successive days, sank the _Soderham_, _Pernambuco_, _Johannes-Russ_, and _Dall-Asfen_--four serious losses to the German gun factories, and even more serious blows to the courage of their carrying trade. The captain of the _Nike_ told Lieutenant Mee on his voyage to Reval, that after E. 19’s first raid no less than fifteen ships were held up at Lulea, awaiting convoys; and after E. 9’s success, the command of the Baltic seemed to have passed for the time out of German hands.
