Let me say at the outset of this chapter that I do not setup as one professing to have any knowledge whatsoever of so-called military science. The more I have seen of the carrying-on of the actual business of war, the less able do I seem to be to understand the meanings of the business. For me strategy remains a closed book. Even the simplest primary lessons of it, the A B C's of it, continue to impress me as being stupid, but none the less unplumbable mysteries.

The physical aspects of campaigning I can in a way grasp. At least I flatter myself that I can. A man would have to be deaf and dumb and blind not to grasp them, did they reveal themselves before him as they have revealed themselves before me. Indeed, if he preserved only the faculty of scent unimpaired he might still be able to comprehend the thing, since, as I have said before, war in its commoner phases is not so much a sight as a great bad smell. As for the rudiments of the system which dictates the movements of troops in large masses or in small, which sacrifices thousands of men to take a town or hold a river when that town and that river, physically considered, appear to be of no consequence whatsoever, those elements I have not been able to sense, even though I studied the matter most diligently. So after sundry months of first-hand observation in one of the theaters of hostilities, I tell myself that the trade of fighting is a trade to be learned by slow and laborious degrees, and even then may be learned with thoroughness only by one who has a natural aptitude for it. Either that, or else I am most extraordinarily thick-headed, for I own that I am still as complete a greenhorn now as I was at the beginning.

Having made the confession which is said to be good for the soul, and which in any event has the merit of blunting in advance the critical judgments of the expert, since he must pity my ignorance and my innocence even though he quarrel with my conclusions, I now assume the rôle of prophet long enough to venture to say that the day of the modern walled fort is over and done with. I do not presume to speak regarding coast defenses maintained for the purposes of repelling attacks or invasions from the sea. I am speaking with regard to land defenses which are assailable by land forces. I believe in the future great wars—if indeed there are to be any more great wars following after this one—that the nations involved, instead of buttoning their frontiers down with great fortresses and ringing their principal cities about with circles of protecting works, will put their trust more and more in transportable cannon of a caliber and a projecting force greater than any yet built or planned. I make this assertion after viewing the visible results of the operations of the German 42-centimeter guns in Belgium and France, notably at Liège in the former country and at Maubeuge in the latter.

Except for purposes of frightening noncombatants the Zeppelins apparently have proved of most dubious value; nor, barring its value as a scout—a field in which it is of marvelous efficiency—does the aëroplane appear to have been of much consequence in inflicting loss upon the enemy. Of the comparatively new devices for waging war, the submarine and the great gun alone seem to have justified in any great degree the hopes of their sponsors.

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.

This having been done, I conceive of the operators as hoisting their guns into position, and posting up a set of rules—even in time of war it is impossible to imagine the Germans doing anything of importance without a set of rules to go by—and working out the distance by mathematics, and then turning loose their potential cataclysms upon the stubborn forts which opposed their further progress. From the viewpoint of the Germans the consequences to the foe must amply have justified the trouble and the cost. For where a 42-centimeter shell falls it does more than merely alter landscape; almost you might say it alters geography.

In the open field, where he must aim his gun with his own eye and discharge it with his own finger, I take it the Kaiser's private soldier is no great shakes as a marksman. The Germans themselves begrudgingly admitted the French excelled them in the use of light artillery. There was wonderment as well as reluctance in this concession. To them it seemed well-nigh incredible that any nation should be their superiors in any department pertaining to the practice of war. They could not bring themselves fully to understand it. It remained as much a puzzle to them as the unaccountable obstinacy of the English in refusing to be budged out of their position by displays of cold steel, or to be shaken by the volleying, bull-like roar of the German charging cry, which at first the Germans counted upon as being almost as efficacious as the bayonet for instilling a wholesome fear of the German war god into the souls of their foes.

While giving the Frenchmen credit for knowing how to handle and serve small field-pieces, the Germans nevertheless insisted that their infantry fire or their skirmish fire was as deadly as that of the Allies, or even deadlier. This I was not prepared to believe. I do not think the German is a good rifle shot by instinct, as the American often is, and in a lesser degree, perhaps, the Englishman is, too. But where he can work the range out on paper, where he has to do with mechanics instead of a shifting mark, where he can apply to the details of gun firing the exact principles of arithmetic, I am pretty sure the German is as good a gunner as may be found on the Continent of Europe to-day. This may not apply to him at sea, for he has neither the sailor traditions nor the inherited naval craftsmanship of the English; but judging by what I have seen I am quite certain that with the solid earth beneath him and a set of figures before him and an enemy out of sight of him to be damaged he is in a class all by himself.

A German staff officer, who professed to have been present, told me that at Manonvilla—so he spelled the name—a 42-centimeter gun was fired one hundred and forty-seven times from a distance of 14,000 meters at a fort measuring 600 meters in length by 400 meters in breadth—a very small target, indeed, considering the range—and that investigation after the capture of the fort showed not a single one of the one hundred and forty-seven shots had been an outright miss. Some few, he said, hit the walls or at the bases of the walls, but all the others, he claimed, had bull's-eyed into the fort itself.
