The medium-size German submarines are quite good-looking boats, but the German mind showed itself clearly in the U cruisers. It has been an axiom at sea since the days of the Vikings, that a thing that looks ugly isn't good seamanship. British submarines are better stream-lined than German boats, and have generally a more "varminty" and clean-run look. The sight of a U cruiser in dry dock recalls to one's mind a pair of pictures once published in 'La Vie Parisienne'--a Paris weekly which has done as much to win the war as any other periodical. The first picture showed a "seventy-five" gun, and standing beside it a girl built on clearly thoroughbred lines, balancing a cartridge on her hand. The second was of a squat 11-inch howitzer, accompanied by 'La Vie's' interpretation of a homely German Frau clutching the great shell to her portly figure. The two pictures illustrate rather well the ideas of our own K-boat designers as compared with the mental state of the authors of the German submarine cruisers. II It used to be a catchword of naval correspondents that "submarine cannot fight submarine." Well, it is true, and it isn't. What can be done is that one submarine submerged can torpedo another submarine on the surface: in which case submarine No. 2 is not really a submarine at the moment. Two submarines may meet and have a gun-action, with possible damage to one or both of them, and much entertainment to their crews; but in such a case neither boat would be acting as a submarine. Throughout the war our boats have been on the look-out for, and ready to engage, any enemy submarines met with. We have had boats, in varying numbers, since the middle of 1915 engaged definitely in submarine-hunting--that is, those boats that could be spared from the all-important task of watching the Bight and its approaches. The anti-submarine boats we sent out simply proceeded to areas where, by inference or by "information received," U-boats might be expected to be working. The ordinary patrol boats on passage to and from their stations, or while watching at their stations for the coming of big ships, often met with U-boats, and naturally took the chances the gods gave them with gun, torpedo, stem, or whatever means seemed best at the moment.
