Subsequently, on subjecting this tale to the acid test of second thought I was compelled to doubt what the staff officer had said. To begin with, I didn't understand how a 42-centimeter gun could be fired one hundred and forty-seven times without its wearing out, for I have often heard that the larger the bore of your gun and the heavier the charge of explosives which it carries, the shorter is its period of efficiency. In the second place, it didn't seem possible after being hit one hundred and forty-seven times with 42-centimeter bombs that enough of any fort of whatsoever size would be left to permit of a tallying-up of separate shots. Ten shots properly placed should have razed it; twenty more should have blown its leveled remainder to powder and scattered the powder.

Be the facts what they may with regard to this case of the fort of Manonvilla—if that be its proper name—I am prepared to speak with the assurance of an eyewitness concerning the effect of the German fire upon the defenses of Maubeuge. What I saw at Liège I have described in a previous chapter of this volume. What I saw at Maubeuge was even more convincing testimony, had I needed it, that the Germans had a 42-centimeter gun, and that, given certain favored conditions, they knew how to handle it effectively.

We spent the better part of a day in two of the forts which were fondly presumed to guard Maubeuge toward the north—Fort Des Sarts and Fort Boussois; but Fort Des Sarts was the one where the 42-centimeter gun gave the first exhibition of its powers upon French soil in this war, so we went there first. To reach it we ran a matter of seven kilometers through a succession of villages, each with its mutely eloquent tale of devastation and general smash to tell; each with its group of contemptuously tolerant German soldiers on guard and its handful of natives, striving feebly to piece together the broken and bankrupt fragments of their worldly affairs.

Approaching Des Sarts more nearly we came to a longish stretch of highway, which the French had cleared of visual obstructions in anticipation of resistance by infantry in the event that the outer ring of defenses gave way before the German bombardment. It had all been labor in vain, for the town capitulated after the outposts fell; but it must have been very great labor. Any number of fine elm trees had been felled and their boughs, stripped now of leaves, stuck up like bare bones. There were holes in the metaled road where misaimed shells had descended, and in any one of these holes you might have buried a horse. A little gray church stood off by itself upon the plain. It had been homely enough to start with. Now with its steeple shorn away and one of its two belfry windows obliterated by a straying shot it had a rakish, cock-eyed look to it.

Just beyond where the church was our chauffeur halted the car in obedience to an order from the staff officer who had been detailed by Major von Abercron, commandant of Maubeuge, to accompany us on this particular excursion. Our guide pointed off to the right. "There," he said, "is where we dropped the first of our big ones when we were trying to get the range of the fort. You see our guns were posted at a point between eight and nine kilometers away and at the start we over-shot a trifle. Still to the garrison yonder it must have been an unhappy foretaste of what they might shortly expect, when they saw the forty-twos striking here in this field and saw what execution they did among the cabbage and the beet patches."

We left the car and, following our guide, went to look. Spaced very neatly at intervals apart of perhaps a hundred and fifty yards a series of craters broke the surface of the earth. Considering the tools which dug them they were rather symmetrical craters, not jagged and gouged, but with smooth walls and each in shape a perfect funnel. We measured roughly a typical specimen. Across the top it was between fifty and sixty feet in diameter, and it sloped down evenly for a depth of eighteen feet in the chalky soil to a pointed bottom, where two men would have difficulty standing together without treading upon each other's toes. Its sides were lined with loose pellets of earth of the average size of a tennis ball, and when we slid down into the hole these rounded clods accompanied us in small avalanches.

We were filled with astonishment, first, that an explosive grenade, weighing upward of a ton, could be so constructed that it would penetrate thus far into firm and solid earth before it exploded; and, second, that it could make such a neat saucer of a hole when it did explode. But there was a still more amazing thing to be pondered. Of the earth which had been dispossessed from the crevasse, amounting to a great many wagonloads, no sign remained. It was not heaped up about the lips of the funnel; it was not visibly scattered over the nearermost furrows of that truck field. So far as we might tell it was utterly gone; and from that we deduced that the force of the explosion had been sufficient to pulverize the clay so finely and cast it so far and so wide that it fell upon the surface in a fine shower, leaving no traces unless one made a minute search for it. Noting the wonder upon our faces, the officer was moved to speak further in a tone of sincere admiration, touching on the capabilities of the crowning achievement of the Krupp works:

"Pretty strong medicine, eh? Well, wait until I have shown you American gentlemen what remains of the fort; then you will better understand. Even here, out in the open, for a radius of a hundred and fifty meters, any man, conceding he wasn't killed outright, would be knocked senseless and after that for hours, even for days, perhaps, he would be entirely unnerved. The force of the concussion appears to have that effect upon persons who are at a considerable distance—it rips their nerves to tatters. Some seem numbed and dazed; others develop an acute hysteria.

"Highly interesting, is it not? Listen then; here is something even more interesting: Within an inclosed space, where there is a roof to hold in the gas generated by the explosion or where there are reasonably high walls, the man who escapes being torn apart in the instant of impact, or who escapes being crushed to death by collapsing masonry, or killed by flying fragments, is exceedingly likely to choke to death as he lies temporarily paralyzed and helpless from the shock. I was at Liège and again here, and I know from my own observations that this is true. At Liège particularly many of the garrison were caught and penned up in underground casements, and there we found them afterward dead, but with no marks of wounds upon them—they had been asphyxiated."
