As he looked at them, Stewart could not but wonder how on earth they had ever been assembled here, and, still more, how they were ever going to be got away again. Also, he thought, how easily might they be cut to pieces by a few batteries of machine-guns posted on that ridge across the river! Looking across, he saw that the army chiefs had foreseen that danger and guarded against it, for a strong body of cavalry had been thrown across the river to screen the advance, while along the bank, behind hasty but well-built intrenchments, long lines of artillery had been massed to repel any attack from that direction.
But no attack came. The little Belgian army evidently had its hands full elsewhere, and was very busy indeed, as the roar of firing both up and down the river testified. And then, as the fugitives walked on along the hillside, they saw that one avenue of advance would soon be open, for a company of engineers, heavily guarded by cavalry and quick-firers, was repairing a bridge whose central span had been blown up by the Belgians as they retreated.
The bridge had connected two little villages, that on the east bank dominated by a beautiful white château placed at the edge of a cliff. Of the villages little remained but smoking ruins, and a flag above the château showed that it had been converted into a staff headquarters.
Where was the owner of the château, Stewart wondered, looking up at it. Where were the women who had sat and gossiped on its terrace? Where were all the people who had lived in those two villages? Wandering somewhere to the westward, homeless and destitute, every one of them—haggard women and hungry children and tottering old men, whose quiet world had turned suddenly to chaos.
“Well,” he said, at last, “it looks as if we shall have to wait until these fellows clear out. We can’t get across the river as long as there is a line like that before it.”
“Perhaps when they begin to advance, they will leave a break in the line somewhere,” his companion suggested. “Or perhaps we can slip across in the darkness. Let us wait and see.”
So they sat down behind the screen of a clump of bushes, and munched their apples, while they watched the scene below. Stewart even ventured to light his pipe again.
A flotilla of boats of every shape and size, commandeered, no doubt, all up and down the river, plied busily back and forth, augmenting the troops on the other side as rapidly as possible; and again Stewart marveled at the absolute order and system preserved in this operation, which might so easily have become confused. There was no crowding, no overloading, no hurrying, but everywhere a calm and efficient celerity. A certain number of men entered each of the boats,—leading their horses by the bridle, if they were cavalry,—and the boats pushed off. Reluctant horses were touched with a whip, but most of them stepped down into the water quietly and without hesitation, showing that they had been drilled no less than their masters, and swam strongly along beside the boat. On the other shore, the disembarkation was conducted in the same unhurried fashion, and the boat swung back into the stream again for another load.
But a great army cannot be conveyed across a river in small boats, and it was not until mid-afternoon, when the repairs on the bridge were finished, that the real forward movement began. From that moment it swept forward like a flood—first the remainder of the cavalry, then the long batteries of quick-firers, then regiment after regiment of infantry, each regiment accompanied by its transport. Looking down at the tangle of wagons and guns and motors, Stewart saw that it was not really a tangle, but an ordered arrangement, which unrolled itself smoothly and without friction.
The advance was slow, but it was unceasing, and by nightfall at least fifteen thousand men had crossed the river. Still the host encamped along it seemed as great as ever. As one detachment crossed, another came up from somewhere in the rear to take its place. Stewart’s brain reeled as he gazed down at them and tried to estimate their number; and this was only one small corner of the Kaiser’s army. For leagues and leagues to north and south it was pressing forward; no doubt along the whole frontier similar hosts were massed for the invasion. It was gigantic, incredible—that word was in his thoughts more frequently than any other. He could not believe his own eyes; his brain refused to credit the evidence of his senses.
