This particular show to which we had been bidden as special guests was to be a foray by night over the tops preceded by artillery preparation. Now such things as these happen every night or every day somewhere on the Western Front; times are when they happen in different sectors at the rate of half a dozen within the twenty-four hours. In the dispatches each one means a line or so of type; in the field it means a few prisoners, a few fresh graves, a few yards of trench work blasted away, a few brier patches of barbed wire to be repatched; in the minds of most readers of the daily papers it means nothing but the tiresome reiteration of a phrase that is tiresome and staled. But to us it meant something. It was our boys who were going in and going over; and our guns were to be partners in the prior enterprise of blazing the way for them.

No matter how much one may read of the cost of war operations in dollars and in time and in labour, I am sure one does not really begin to appreciate the staggering expenditure of all three that is requisite to accomplish even the smallest of aggressive movements until one has opportunity, as we now had, to see with one's own eyes what necessarily had to be done by way of preliminary.

Take for instance the present case. The raid in hand was to be no great shakes of a raid. Forty-five Americans and three times their number of Frenchmen would participate in it. Within twenty minutes, if all went well—and it did—they would have returned from their excursion into hostile territory, with prisoners perhaps, or else with notes and letters taken from the bodies of dead enemies which might serve to give the Intelligence Department a correct appraisal of the character and numbers of the troops opposing us in this sector. In the vast general scheme of the campaign now about renewing itself it would be no more than an inconsequential pin prick in the foe's side—a thing to be done and mentioned briefly in the dispatches, and then forgotten.

But mark you how great and how costly the artillery accompaniment must be. More than a hundred guns, ranging in calibre from a nine-inch bore down to a three-inch bore, would join in the preparation and in the barrage fire. More than ten thousand rounds of ammunition would be fired, this not taking into account the supplies for the forty-three machine guns and for the batteries of trench mortars which were to cooperate. Many a great battle of our Civil War had been fought out with the expenditure on both sides of one-tenth or one-twentieth part the gross weight of metal that would be directed at the boche beyond the ridge. The cost for munitions alone, excluding every other item of a score of items, might run to a quarter of a million dollars; might conceivably run considerably beyond that figure. And the toil performed and the pains taken beforehand to insure success—wowie!

For days past the French had been bringing up pieces and massing them here for the purpose of this one little stab at the Hun's armoured flank. As we travelled hither we had seen the motor-drawn guns labouring along the wide high roads; had seen the ammunition trucks crawling forward in long lines; had seen at every tiny village behind the Front the gun crews resting in bad streets named for good saints. By the same token, on the following day, which was Sunday, we were to see the same thing repeated, except that then the procession would be headed the other way—going back to repeat the same wearisome proceeding elsewhere.

Days, too, had been spent in planning the raid; in mapping out and plotting out the especial spot chosen for attack; in coordinating all the arms of the service which would be employed; in planning signals for the show and drilling its actors. And now all this preparation requisite and essential to the carrying out of the undertaking had been completed; and all the guns had been planted in their appointed places and craftily hidden; and all the shells had been brought up—thousands of tons of them—and properly bestowed; and the little handful of men who were to have a direct hand in the performance of the main job, for which all the jest would be purely preliminary, had been chosen and sent forward to ordained stations, there to await the word. And so up we got from table and went out across a threshold, which quaked like a living thing as we crossed it, to see the spectacular side of the show.

Inside the house the air had been churned up and down by the detonations. Outside literally it was being rent into fine bits. One had the feeling that the atmosphere was all shredded up fine, so that instead of lying in layers upon the earth it floated in tom and dishevelled strips; one had the feeling that the upper ether must be full of holes and voids and the rushing together of whipped and eddying wind currents. This may sound incoherent, but I find in my vocabulary no better terninology to convey a sense of the impression that possessed me as I stepped forth into the open.

We had known in advance that there were guns in great number disposed about the surrounding terrain. Walking about under military guidance in the afternoon we had seen sundry batteries ensconced under banks, in thickets and behind low natural parapets where the earth ridged up; and had noted how cunningly they had been concealed from aëroplanes scouting above and from the range of field glasses in the German workings on beyond.

But we had no notion until then that there were so many guns near by or that some of them were so dose to the village where we had stopped to eat. We must almost have stepped on some of them without once suspecting their presence. The ability of the French so well to hide a group of five big pieces, each with a carriage as large as a two-ton truck and each with a snout projecting two or three yards beyond it, and with a limber projecting out behind it, shows what advances the gentle arts of ambuscade and camouflage have made since this war began. Seen upon the open road a big cannon painted as it is from muzzle to breach with splotchings of yellows and browns and ochres seems, for its size, the most conspicuous thing in the world. But once bedded down in its nest, with its gullet resting upon the ring back of earth that has been thrown up for it, and a miracle of protective colouration instantaneously is achieved. Its whole fabric seems to melt into and become a part of the soil and the withered herbage and the dirt-coloured sandbags which encompass it abaft, alongside and before. It is the difference between a mottled snake crawling across a brick sidewalk and the same snake coiled and motionless amid dried leaves and boulders in the woods. Nature always has protected her wild creatures thus; it took the greatest of wars for mankind to learn a lesson that is as old as creation is.

Standing there in the square of the wrecked village we could sense that in all manner of previously unsuspected coverts within the immediate vicinity guns were at work—guns which ranged from the French seventy-fives to big nine-inch howitzers. As yet twilight had not sufficiently advanced for us to see the flash of the firing, and of course' nowadays there is mighty little smoke to mark the single discharge of a single gun; but we could tell what went on by the testimony of a most vast tumult.
