Since I came back out of the war zone I have met persons who questioned the existence of a 42-centimeter gun, they holding it to be a nightmare created out of the German imagination with intent to break the confidence of the enemies of Germany. I did not see a 42-centimeter gun with my own eyes, and personally I doubt whether the Germans had as many of them as they claimed to have; but I talked with one entirely reliable witness, an American consular officer, who saw a 42-centimeter gun as it was being transported to the front in the opening week of the war, and with another American, a diplomat of high rank, who interviewed a man who saw one of these guns, and who in detailing the conversation to me said the spectator had been literally stunned by the size and length and the whole terrific contour of the monster. Finally, I know from personal experience that these guns have been employed, and employed with a result that goes past adequate description; but if I hadn't seen the effect of their fire I wouldn't have believed it were true. I wouldn't have believed anything evolved out of the brains of men and put together by the fingers of men could operate with such devilish accuracy to compass such utter destruction. I would have said it was some planetic force, some convulsion of natural forces, and not an agency of human devisement, that turned Fort Loncin inside out, and transformed it within a space of hours from a supposedly impregnable stronghold into a hodgepodge of complete and hideous ruination. And what befell Fort Loncin on the hills behind Liège befell Fort Des Sarts outside of Maubeuge, as I have reason to know. When the first of the 42-centimeters emerged from Essen it took a team of thirty horses to haul it; and with it out of that nest of the Prussian war eagle came also a force of mechanics and engineers to set it up and aim it and fire it. Here, too, is an interesting fact that I have not seen printed anywhere, though I heard it often enough in Germany: by reason of its bulk the 42-centimeter must be mounted upon a concrete base before it can be used. Heretofore the concrete which was available for this purpose required at least a fortnight of exposure before it was sufficiently firm and hardened; but when Fräulein Bertha Krupp's engineers escorted the Fräulein's newest and most impressive steel masterpiece to the war, they brought along with them the ingredients for a new kind of concrete; and those who claim to have been present on the occasion declare that within forty-eight hours after they had mixed and molded it, it was ready to bear the weight of the guns and withstand the shock of their recoil.
