"Deliver this to Captain Leboeuf at Visé," ordered the Major. "In view of the German advance, he is to cross the river and impede the enemy as much as possible, retiring upon Fort de Pontisse if in danger of being outflanked." Then dropping the official voice, he added in English, "Since Madame de la Barre would pay no heed to my request, it is necessary for strategic reasons to occupy her house. You may now have an opportunity of seeing your sister, Monsieur Everest. There are, I believe, only our pupils there during the holidays. Captain Leboeuf will arrange for them to be sent into Maastricht by train, or by a carriage if railway communication is interrupted. They can then proceed to Brussels in the ordinary way. You might give this to Mademoiselle Yvonne for incidental expenses for herself and her friend, your sister," and the Major handed Kenneth a packet containing a sheaf of notes. "Be cautious," he added. "The Germans have already advanced upon Lembourg." The lads saluted and withdrew. A minute later they were dashing over the drawbridge, bound on their first duty as dispatch-riders in the Belgian army, though with a semi-official motive. Away on their right came the rapid booming of light artillery fire. Beyond the woods of Verviers a thick cloud of black smoke rose sullenly in the heavy air. Their route lay along a fairly level road bounded on each side by tall trees. In the centre was a strip of _pavé_, but between it and the ditch on either hand was a dusty path which afforded good going. The cyclists were soon touching thirty miles an hour, the rapid beats of their engines drowning the noise of the distant cannonade. Once they had to slow down in order to allow a cart to draw up on one side. The floor of the cart was covered with straw, and on the straw lay some strange objects. The lads did not realize what these burdens were. They were new to the game of war, but not for long. Presently they noticed a group of soldiers approaching. Thrice the lads sounded their horns without effect. Again they had to slow down. "Good heavens! Look!" ejaculated Kenneth. The men were limping painfully. One had his arm thrown around a comrade's neck, and his head falling limply upon the other's shoulder. Another, his head bound by a blood-stained scarf, was using the butt of his rifle as a crutch. "There's been an action already," said Rollo. "Yes, and on the Visé road," added his companion. "Let's push on. I hope we are not too late." During the slowing-down process the thunder of the guns became horribly distinct. There was terrific firing in the direction of Argenteau. More, there were heavy Belgian losses, for the men they had just passed were but the van of a ghastly procession of wounded. At Argenteau a body of reserves was in possession of the village. Barricades had been hastily constructed, walls of buildings loopholed, and barbed-wire entanglements placed across the road. "Halte-là!"
