In beginning this job I find myself casting about for comparisons to set up against the vision of a full German army of seven army corps on the march. I think of the tales I have read and the stories I have heard of other great armies: Alaric's war bands and Attila's; the First Crusade; Hannibal's cohorts, and Alexander's host, and Cæsar's legions; the Goths and the Vandals; the million of Xerxes—if it was a million—and Napoleon starting for Moscow.

It is of no use. This Germanic horde, which I saw pouring down across Belgium, bound for France, does not in retrospect seem to me a man-made, man-managed thing. It seems more like a great, orderly function of Nature; as ordained and cosmic as the tides of the sea or the sweep of a mighty wind. It is hard to believe that it was ever fashioned of thousands of separate atoms, so perfectly is it welded into a whole. It is harder still to accept it as a mutable and a mortal organism, subject to the shifts of chance and mischance.

And then, on top of this, when one stops to remember that this army of three hundred thousand men and a hundred thousand horses was merely one single cog of the German military machine; that if all the German war strength were assembled together you might add this army to the greater army and hardly know it was there—why, then, the brain refuses to wrestle with a computation so gigantic. The imagination just naturally bogs down and quits.

I have already set forth in some detail how it came to pass that we went forth from Brussels in a taxicab looking for the war; and how in the outskirts of Louvain we found it, and very shortly thereafter also found that we were cut off from our return and incidentally had lost not only our chauffeur and our taxicab but our overcoats as well. There being nothing else to do we made ourselves comfortable along side the Belgian Lion Café in the southern edge of Louvain, and for hours we watched the advance guard sliding down the road through a fog of white dust.

Each time a break came in the weaving gray lines we fancied this surely was all. All? What we saw there was a puny dribbling stream compared with the torrent that was coming. The crest of that living tidal wave was still two days and many miles to the rearward. We had seen the head and a little of the neck. The swollen body of the myriad-legged gray centipede was as yet far behind.

As we sat in chairs tilted against the wall and watched, we witnessed an interesting little side play. At the first coming of the German skirmishers the people of this quarter of the town had seemed stupefied with amazement and astonishment. Most of them, it subsequently developed, had believed right up to the last minute that the forts of Liège still held out and that the Germans had not yet passed the gateways of their country, many kilometers to the eastward. When the scouts of the enemy appeared in their streets they fell for the moment into a stunned state. A little later the appearance of a troop of Uhlans had revived their resentment. We had heard that quick hiss and snarl of hatred which sprang from them as the lancers trotted into view on their superb mounts out of the mouth of a neighboring lane, and had seen how instantaneously the dull, malignant gleam of gun metal, as a sergeant pulled his pistol on them, had brought the silence of frightened respect again.

It now appeared that realization of the number of the invaders was breeding in the Belgians a placating spirit. If a soldier fell out of line at the door of a house to ask for water, all within that house strove to bring the water to him. If an officer, returning from a small sortie into other streets, checked up to ask the way to rejoin his command, a dozen eager arms waved in chorus to point out the proper direction, and a babble of solicitous voices arose from the group about his halted horse.

Young Belgian girls began smiling at soldiers swinging by and the soldiers grinned back and waved their arms. You might almost have thought the troops were Allies passing through a friendly community. This phase of the plastic Flemish temperament made us marvel. When I was told, a fortnight afterward, how these same people rose in the night to strike at these their enemies, and how, so doing, they brought about the ruination of their city and the summary executions of some hundreds of themselves, I marveled all the more.

Presently, as we sat there, we heard—above the rumbling of cannon wheels, the nimble clunking of hurrying hoofs and the heavy thudding of booted feet, falling and rising all in unison—a new note from overhead, a combination of whir and flutter and whine. We looked aloft. Directly above the troops, flying as straight for Brussels as a homing bee for the hive, went a military monoplane, serving as courier and spy for the crawling columns below it. Directly, having gone far ahead, it came speeding back, along a lower air lane and performed a series of circling and darting gyrations, which doubtlessly had a signal-code meaning for the troops. Twice or three times it swung directly above our heads, and at the height at which it now evoluted we could plainly distinguish the downward curve of its wing-planes and the peculiar droop of the rudder—both things that marked it for an army model. We could also make out the black cross painted on its belly as a further distinguishing mark.

To me a monoplane always suggests a bird when it does not suggest an insect or a winged reptile; and this monoplane particularly suggested the bird type. The simile which occurred to me was that of the bird which guards the African rhinoceros; after that it was doubly easy to conceive of this army as a rhinoceros, having all the brute strength and brute force which are a part of that creature, and its well-armored sides and massive legs and deadly horned head; and finally its peculiar fancy for charging straight at its objective target, trampling down all obstacles in the way.
