Scarcely had the first gone by, when a second gun came rolling along the road, followed by its crew and its ammunition-train; and then a third appeared, seemingly more formidable than either of the others. "These Germans are certainly a wonderful people," said Stewart, following the three monsters with his eyes as they dwindled away westward along the road. "They may be vain and arrogant and self-confident; apparently they haven't much regard for the rights of others. But they are thorough. We must give them credit for that! They are prepared for everything." "Yes," agreed his companion; "for everything except one thing." "And that?" "The spirit of a people who love liberty. Neither cannon nor armies can conquer that! The German Staff believed that Belgium would stand aside in fear." "Surely you don't expect Belgium to win?" "Oh, no! But every day she holds the German army here is a battle won for France. Oh, France will honor Belgium now! See--the army has been stopped. It is no longer advancing!" What was happening to the westward they could not see, or even guess, but it was true that the helmeted host had ceased its march, had broken ranks, and was stacking arms and throwing off its accouterments in the fields along the road. The halt was to be for some time, it seemed, for everywhere camp-kitchens were being hauled into place, fires started, food unloaded. "Come on! come on!" urged the girl. "We must reach the Meuse before this tide rolls across it." They pressed forward again along the wooded hillside. Twice they had to cross deep valleys which ran back into the mountain, and once they had a narrow escape from a cavalry patrol which came cantering past so close upon their heels that they had barely time to throw themselves into the underbrush. They could see, too, that even in the hills caution was necessary, for raiding parties had evidently struck up into them, as was proved by an occasional column of smoke rising from a burning house. Once they came upon an old peasant with a face wrinkled like a withered apple, sitting staring down at the German host, so preoccupied that he did not even raise his eyes as they passed. And at last they came out above the broad plain where the Vesdre flows into the Meuse. Liège, with its towers and terraced streets, was concealed from them by a bend in the river and by a bold bluff which thrust out toward it from the east--a bluff crowned by a turreted fortress--perhaps the same they had seen the night before--which was vomiting flame and iron down into the valley.
