It is possibly something to do with this trait that brought the major part of the U-boat successes into the hands of a few special officers. The greater part of the captains did little; a few "aces" compiled huge lists of sunken tonnage to their credit (or otherwise). Judged by British Admiralty standards of efficiency, those few are the only ones who in our Service would have been retained at all. However, it is time I went on with the doings of our own boats. Human beings are so much more important in war than are machines, that it is a temptation to describe them for preference. I would like to be able to talk about the submarine seamen also, but there is no ground for comparison between our own men and the German machine-made U-boat hand. One thinks of the German men as just things that opened or closed valves when barked at, and who never took any interest in what was going on outside their particular stations, or in what the boat was doing. Our sailors are--well, to put it "socially," they seem to belong more to the middle than the lower class. They are certainly not machine-made or dull, and they are not reluctant to act according to their own judgment in the absence of an officer's orders. During the war our submarines sank 54 enemy warships and 274 other vessels. These figures do not, of course, include the many warships which were damaged but which were got back into harbour, although they include the U-boats which our submarines destroyed. German ships are very well subdivided in compartments and take a lot of killing. Certainly on a modern war-vessel one torpedo-hit is very little use; it takes about four to make certain of sinking her. The _Moltke_ (battle-cruiser) was hit with one torpedo forward in the Baltic by Commander Laurence, and again off Hiorn's Reef by Lieutenant Allen (right aft this time); on each occasion she got home safely. Our own light cruiser _Falmouth_ had to receive four torpedoes in succession before she sank. The _Prinz Adalbert_ was torpedoed by Commander Horton in the Baltic off Cape Kola and returned safely to Kiel (she could not take a hint, however, and after a long interval for repair she went east again and met Commander Goodheart of "E 8," who sank her). Commander Laurence in "J 1" hit the _Kronprinz_ and _Grosser Kurfurst_ (battleships) in the North Sea, but both were got home safely. Our later submarines were fitted with larger torpedoes and tubes, but the boats fitted with eighteen-inch torpedoes made up the larger part of our flotillas, and it was realised by both our own and the enemy submarines that it took several hits with the smaller-size weapon to finish off a large ship. Perhaps the clearest case on record is that of the _Marlborough_, the ship being hit by a torpedo at the Jutland battle and remaining in the line at the Fleet speed and continuing her firing as if she had never been touched. Older ships, as both sides found to their cost, were much more vulnerable. Probably the Turkish
