"Fired starboard beam tube 1100 yards' range, hitting her forward on starboard side. The cruiser (_Ancona_ class) swung round and stopped. At 1.55 P.M. fired stern tube at 1200 yards. Torpedo hit just abaft main-mast, and after-magazine blew up. Three minutes later there was no sign of her." The German ships torpedoed in the Baltic seem to have had touchy magazines. Commander Goodhart "E 8" met the _Prinz Adalbert_ on October 23rd, 1915. She was zigzagging slightly and going 15 knots, with two destroyers zigzagging ahead as a screen. The torpedo was fired at the fore-bridge as she passed, and-- "Observed very vivid flash of explosion along water-line at point of aim. This was immediately followed by a very heavy concussion, and the entire ship was completely hidden by a huge column of thick grey smoke--fore magazine having evidently been exploded by torpedo. As many portions of the ship were observed to be falling in the water all round, I proceeded to 50 feet depth." The range of this shot was about 1300 yards. This comparatively long distance was fortunate, as the resultant explosion would have probably caused a terrific shock to "E 8" had she happened to fire from closer. The E boats in the Baltic came from Harwich _viâ_ the Sound. It sounds simple, but it was a remarkably difficult and dangerous trip. For six miles in the narrows it is too shallow for a submarine to submerge. The boats had to trim down and go along with their conning-towers showing and their keels bumping along the rocky bottom. The traffic--both neutral and enemy--was so thick that it was not so much a question of avoiding being seen, as of actually avoiding collision. A maze of moving and fixed lights, searchlights, star-shells, and attempts to ram made up a nightmare of navigational difficulties to add to the normal anxiety of passing through thick traffic in a narrow channel. It was really a marvel that any boats got through safely at all. III Throughout this history I am giving selections from despatches of typical "contacts" with the enemy, or of those which describe exciting incidents on patrol; but I don't want to give the idea that submarine patrol work was one whirl of gaiety, and that a boat had only to go to sea in order to find a target. The facts are very different. A boat might do a matter of twenty trips without meeting any kind of chance at an enemy, and I suppose that each boat averaged two to three thousand miles of diving between chances. The following description of routine in a patrol boat must stand for four years of blank days in the North Sea, Atlantic, or Mediterranean:--
