I endeavoured to simulate an air of unconcern which I was far from feeling. Not that I was a prey to physical fear; I flatter myself it is so far unknown to me, and there was no great danger, but simply that I longed to know what was happening. At length I heard the welcome order: "Starboard tube. Stand by!" Which was followed almost immediately by the order: "Fire!" There was a kind of coughing grunt, and the starboard torpedo proceeded on its errand of destruction. Every ear was strained for the sound of the explosion, but all we were vouchsafed was a torrent of blasphemy from Alten. The torpedo had jumped clean out of the water a hundred yards short of the steamer, and had then evidently dived under the ship; so I gathered later when Alten had calmed down somewhat. We were about to surface and give her the gun, when luckily Alten took a good sweep round with the skyscraper and discovered one of those wretched little airships about a mile away, coming towards the steamer, which was wailing piteously, on her syren. As the chart showed forty metres we decided to bottom and have lunch. Over lunch we discussed the misadventure. Alten was loud in his curses of Tanzerman (the torpedo lieutenant at Bruges), from whom he had got the torpedo in guaranteed good condition only forty-eight hours before we sailed. He launched forth into a tirade against the torpedo staff at Bruges, and, warming to his subject, he roundly abused the whole of the depot personnel, whom he stigmatized as a set of hard-drinking, shore-loafing ruffians, who were incapable of realizing that they existed for the benefit of the boats' personnel and "material." I naturally disagreed, and did so the more readily that I conscientiously disagree with him. I find that there is a tendency on the part of some of these submarine officers, who have been U-boating a long time, to get into narrow grooves. Most reserve officers are not like this, as they have only been in during the war. Alten is an exception; he left the Hamburg-Amerika on two years' half pay in 1912, and was, of course, kept on in 1914. After all, the depot staff are Germans, and as such labour for the Fatherland, and though their work in office and workship is not so dangerous as ours, on the other hand they have not got the stimulation before their eyes, of glory to be gained. Personally I am of the opinion that the torpedo broke surface because, being fired from the outside tubes, it probably started too shallow, dived deep, recovered shallow and dived deep, broke surface and dived very deep. A sticky motor or sluggish weight would give this effect.
