The latter question is still difficult to answer, even if one takes into account a system of "compulsory volunteering," and also the fact that standardised boats can be worked by standardised and partly-trained men. What it would have come to was indicated by the trend of U-boat war results in 1918. It would have implied a good deal of real work being performed by a few experienced and trained crews, and a lot of blank trips and half-hearted performances by a mass of other crews, the mortality among the latter rising to a terrible percentage. It will always be the same; a good personnel will do well in any boat--a bad personnel will do badly, however good the boat is. In the remarks quoted from a German officer, I have referred to three incidents in connection with the activities of our own submarines. I will give them in their order, as they appeared to the officers concerned. It was "E 42" (Lieutenant C. Allen) that met the German battle-cruisers on 25th April 1918, and, the enemy being homeward bound, fired a torpedo into the _Moltke_ as she passed Hiorn's Reef:-- "A.M. 0630. While on surface, sighted hostile sea-plane--high up, but close. "Dived to 60 feet (4 bombs). Surfaced for observations. Saw smoke bearing N.E. Dived. "Sighted a battle-cruiser escorted by three torpedo-boats. Altered course, and proceeded utmost speed to attack. Fired starboard bow tube (quarter shot). Range 2000-2500 yards. Heard sound of explosion a long way off--possible hit." (The "possible hit," as a matter of fact, caused the _Moltke_ to be towed in a very precarious condition all the way home.) "About 5 depth-charges and 20 lance-bombs were dropped at me after the shot. Courses as requisite for getting clear." The next incident, of the attack in the Weser river, has a story behind it. Lieut. Varley ("H 5") reports as follows:-- "11th July 1916: Fixed by Terschelling Light. Proceeded towards Ems." (At this moment "H 5," being bored with the patrol billet assigned to her, and thirsting for trouble, left her patrol to see what was going on in Germany.--Author.) "12th July, 2 A.M.: Dived off Borkum. 10.25 P.M.: dived to avoid destroyer. 10.50: surface, proceeding east, sighted enemy patrol vessel, but steamed round her without being seen. "13th July, 1 A.M.: Sighted Wangeroog and Rote Land Lights. 9.58 P.M.: sighted destroyer about 2 miles N.W. from Aussen Jahde Lightship. "14th July, 12.34 A.M.: Dived--several destroyers of G 101 class in sight. Attacked same. 10 A.M.: sighted hostile submarine--attacked same. Torpedoed submarine with one torpedo amidship. Surface to look for survivors. Was put down immediately by destroyer, who opened fire. 10.41: altered course N., and went to bottom in 18 fathoms. Heard loud explosion. Destroyers sweeping for us all day.
