For once in my life--and doubtlessly only once--I saw now understandingly a battle front.

It was spread before me--lines and dots and dashes on a big green and brown and yellow map. Why, the whole thing was as plain as a chart. I had a reserved seat for the biggest show on earth.

To be sure it was a gallery seat, for the terrace from which we started stood fully five hundred feet above the bottom of the valley, and we had ascended approximately seven hundred feet above that, giving us an alt.i.tude of, say, twelve hundred feet in all above the level of the river; but a gallery seat suited me. It suited me perfectly. The great plateau, stretching from the high hill behind us, to the river in front of us, portrayed itself, when viewed from aloft, as a shallow bowl, alternately grooved by small depressions and corrugated by small ridges.

Here and there were thin woodlands, looking exactly like scrubby clothesbrushes. The fields were checkered squares and oblongs, and a ruined village in the distance seemed a jumbled handful of children's gray and red blocks.

The German batteries appeared now to be directly beneath us--some of them, though in reality I imagine the nearest one must have been nearly a mile away on a bee line. They formed an irregular horseshoe, with the open end of it toward us. There was a gap in the horseshoe where the calk should have been. The German trenches, for the most part, lay inside the encircling lines of batteries. In shape they rather suggested a U turned upside down; yet it was hard to ascribe to them any real shape, since they zigzagged so crazily. I could tell, though, there was sanity in this seeming madness, for nearly every trench was joined at an acute angle with its neighbor; so that a man, or a body of men, starting at the rear, out of danger, might move to the very front of the fighting zone and all the time be well sheltered. So far as I could make out there were but few breaks in the sequence of communications. One of these breaks was almost directly in front of me as I stood facing the south.

The batteries of the Allies and their infantry trenches, being so much farther away, were less plainly visible. I could discern their location without being able to grasp their general arrangement. Between the nearer infantry trenches of the two opposing forces were tiny dots in the ground, each defined by an infinitesimal hillock of yellow earth heaped before it--observation pits these, where certain picked men, who do not expect to live very long anyway, hide themselves away to keep tally on the effect of the sh.e.l.ls, which go singing past just over their heads to fall among the enemy, who may be only a few hundred feet or a few hundred yards away from the observers.

It was an excessively busy afternoon among the guns. They spoke continually--now this battery going, now that; now two or three or a dozen together--and the sound of them came up to us in claps and roars like summer thunder. Sometimes, when a battery close by let go, I could watch the thin, shreddy trail of fine smoke that marked the arched flight of a shrapnel bomb, almost from the very mouth of the gun clear to where it burst out into a fluffy white powder puff inside the enemy's position.

Contrariwise, I could see how sh.e.l.ls from the enemy crossed those sh.e.l.ls in the air and curved downward to scatter their iron sprays among the Germans. In the midst of all this would come a sharp, spattering sound, as though hail in the height of the thunder shower had fallen on a tin roof; and that, I learned, meant infantry firing in a trench somewhere.

For a while I watched some German soldiers moving forward through a criss-cross of trenches; I took them to be fresh men going in to relieve other men who had seen a period of service under fire. At first they suggested moles crawling through plow furrows; then, as they progressed onward, they shrank to the smallness of gray grub-worms, advancing one behind another. My eye strayed beyond them a fair distance and fell on a row of tiny scarlet dots, like cochineal bugs, showing minutely but clearly against the green-yellow face of a ridgy field well inside the forward batteries of the French and English. At that same instant the lieutenant must have seen the crawling red line too. He pointed to it.

"Frenchmen," he said; "French infantrymen's trousers. One cannot make out their coats, but their red trousers show as they wriggle forward on their faces."

Better than ever before I realized the idiocy of sending men to fight in garments that make vivid targets of them.

My companion may have come up for pleasure, but if business obtruded itself on him he did not neglect it. He bent to his telephone and spoke briskly into it. He used German, but, after a fashion, I made out what he said. He was directing the attention of somebody to the activities of those red trousers.

I intended to see what would follow on this, but at this precise moment a sufficiently interesting occurrence came to pa.s.s at a place within much clearer eye range. The gray grub-worms had shoved ahead until they were gray ants; and now all the ants concentrated into a swarm and, leaving the trenches, began to move in a slanting direction toward a patch of woods far over to our left. Some of them, I think, got there, some of them did not. Certain puff-b.a.l.l.s of white smoke, and one big smudge of black smoke, which last signified a bomb of high explosives, broke over them and among them, hiding all from sight for a s.p.a.ce of seconds. Dust clouds succeeded the smoke; then the dust lifted slowly.

Those ants were not to be seen. They had altogether vanished. It was as though an anteater had come forth invisibly and eaten them all up.

Marveling at this phenomenon and unable to convince myself that I had seen men destroyed, and not insects, I turned my head south again to watch the red ladybugs in the field. Lo! They were gone too! Either they had reached shelter or a painful thing had befallen them.

The telephone spoke a brisk warning. I think it made a clicking sound.

I am sure it did not ring; but in any event it called attention to itself. The other man clapped his ear to the receiver and took heed to the word that came up the dangling wire, and snapped back an answer.

"I think we should return at once," he said to me over his shoulder.

"Are you sufficiently wearied?"

I was not sufficiently wearied--I wasn't wearied at all--but he was the captain of the ship and I was not even paying for my pa.s.sage.

The car jerked beneath our unsteady feet and heeled over, and I had the sensation of being in an elevator that has started downward suddenly, and at an angle to boot. The balloon resisted the pressure from below.

It curled up its tail like a fat b.u.mblebee trying to sting itself, and the guy ropes, to which I held with both hands, snapped in imitation of the rigging of a sailboat in a fair breeze. Plainly the balloon wished to remain where it was or go farther; but the pull of the cable was steady and hard, and the world began to rise up to meet us. Nearing the earth it struck me that we were making a remarkably speedy return. I craned my neck to get a view of what was directly beneath.

The six-horse team was advancing toward us at a brisk canter and the drum turned fast, taking up the slack of the tether; but, as though not satisfied with this rate of progress, several soldiers were running back and jumping up to haul in the rope. The sergeant who took care of the telephone was hard put to it to coil down the twin wires. He skittered about over the gra.s.s with the liveliness of a cricket.

Many soiled hands grasped the floor of our hamper and eased the jar of its contact with the earth. Those same hands had redraped the rim with sandbags, and had helped us to clamber out from between the stay ropes, when up came the young captain who spelled the lieutenant as an aerial spy. He came at a run. Between the two of them ensued a sharp interchange of short German sentences. I gathered the sense of what pa.s.sed.

"I don't see it now," said, in effect, my late traveling mate, staring skyward and turning his head.

"Nor do I," answered the captain. "I thought it was yonder." He flirted a thumb backward and upward over his shoulder.

"Are you sure you saw it?"

"No, not sure," said the captain. "I called you down at the first alarm, and right after that it disappeared, I think; but I shall make sure."

He snapped an order to the soldiers and vaulted nimbly into the basket.

The horses turned about and moved off and the balloon rose. As for the lieutenant, he spun round and ran toward the edge of the field, fumbling at his belt for his private field gla.s.ses as he ran. Wondering what all this bother was about--though I had a vague idea regarding its meaning-- I watched the ascent.

I should say the bag had reached a height of five hundred feet when, behind me, a hundred yards or so away, a soldier shrieked out excitedly.

Farther along another voice took up the outcry. From every side of the field came shouts. The field was ringed with clamor. It dawned on me that this spot was even more efficiently guarded than I had conceived it to be.

The driver of the wagon swung his lumbering team about with all the strength of his arms, and back again came the six horses, galloping now.

So thickly ma.s.sed were the men who s.n.a.t.c.hed at the cable, and so eagerly did they grab for it, that the simile of a hot handball scrimmage flashed into my thoughts. I will venture that balloon never did a faster homing job than it did then.

Fifty men were pointing aloft now, all of them crying out as they pointed:

"Flyer! French flyer !"

I saw it. It was a monoplane. It had, I judged, just emerged from a cloudbank to the southward. It was heading directly toward our field.

It was high up--so high up that I felt momentarily amazed that all those Germans could distinguish it as a French flyer rather than as an English flyer at that distance.

As I looked, and as all of us looked, the balloon basket hit the earth and was made fast; and in that same instant a cannon boomed somewhere well over to the right. Even as someone who knew sang out to us that this was the balloon cannon in the German aviation field back of the town opening up, a tiny ball of smoke appeared against the sky, seemingly quite close to the darting flyer, and blossomed out with downy, dainty white petals, like a flower.

The monoplane veered, wheeled and began to drive in a wriggling, twisting course. The balloon cannon spoke again. Four miles away, to the eastward, its fellow in another aviation camp let go, and the sound of its discharge came to us faintly but distinctly. Another smoke flower unfolded in the heavens, somewhat below the darting airship.

Both guns were in action now. Each fired at six-second intervals. All about the flitting target the smokeb.a.l.l.s burst--above it, below it, to this side of it and to that. They polka-dotted the heavens in the area through which the Frenchman scudded. They looked like a bed of white water lilies and he like a black dragonfly skimming among the lilies.

It was a pretty sight and as thrilling a one as I have ever seen.

I cannot a.n.a.lyze my emotions as I viewed the spectacle, let alone try to set them down on paper. Alongside of this, big-game hunting was a commonplace thing, for this was big-game hunting of a magnificent kind, new to the world--revolving cannon, with a range of from seven to eight thousand feet, trying to bring down a human being out of the very clouds.

He ran for his life. Once I thought they had him. A sh.e.l.l burst seemingly quite close to him, and his machine dipped far to one side and dropped through s.p.a.ce at that angle for some hundreds of feet apparently.

A yell of exultation rose from the watching Germans, who knew that an explosion close to an aeroplane is often sufficient, through the force of air concussion alone, to crumple the flimsy wings and bring it down, even though none of the flying shrapnel from the bursting bomb actually touch the operator or the machine.

However, they whooped their joy too soon. The flyer righted, rose, darted confusingly to the right, then to the left, and then bored straight into a woolly white cloudrack and was gone. The moment it disappeared the two balloon cannon ceased firing; and I, taking stock of my own sensations, found myself quivering all over and quite hoa.r.s.e.

I must have done some yelling myself; but whether I rooted for the flyer to get away safely or for the cannon to hit him, I cannot for the life of me say. I can only trust that I preserved my neutrality and rooted for both.

Subsequently I decided in my own mind that from within the Allies' lines the Frenchman saw us--meaning the lieutenant and myself--in the air, and came forth with intent to bombard us from on high; that, seeing us descend, he hid in a cloud ambush, venturing out once more, with his purpose renewed, when the balloon reascended, bearing the captain. I liked to entertain that idea, because it gave me a feeling of having shared to some degree in a big adventure.

As for the captain and the lieutenant, they advanced no theories whatever. The thing was all in the day's work to them. It had happened before. I have no doubt it has happened many times since.

Chapter 10

In the Trenches Before Rheims

After my balloon-riding experience what followed was in the nature of an anticlimax--was bound to be anti-climactic. Yet the remainder of the afternoon was not without action. Not an hour later, as we stood in a battery of small field guns--guns I had watched in operation from my lofty gallery seat--another flyer, or possibly the same one we had already seen, appeared in the sky, coming now in a long swinging sweep from the southwest, and making apparently for the very spot where our party had stationed itself to watch the trim little battery perform.

It had already dropped some form of deadly souvenir we judged, for we saw a jet of black smoke go geysering up from a woodland where a German corps commander had his field headquarters, just after the airship pa.s.sed over that particular patch of timber. As it swirled down the wind in our direction the vigilant balloon guns again got its range, and, to the throbbing tune of their twin boomings, it ducked and dodged away, executing irregular and hurried upward spirals until the cloud-fleece swallowed it up.
