They had seen trainloads of soldiers all sweeping toward the west and south. Heavy traction engines had been noticed moving slowly along country roads, and drawing enormous guns behind them. Thousands of motor trucks, each also loaded to the limit with men in helmets, had been seen scurrying along.

All these things pointed to a growing fear that some terrible calamity was impending over poor Europe, so that possibly the long talked of World’s War might be nearer than most people across the Atlantic dreamed of.

To comfort Bumpus, Thad had solemnly promised him that no matter what happened they would do everything in their power to forge ahead and reach Antwerp. When he made that brotherly promise Thad could not have foreseen one-tenth of the tremendous difficulties that would have to be surmounted before it could ever be carried into execution; but once it was given he had such a tenacious will that the leader of the Silver Fox Patrol was bound to try and keep his word.

Their other comrade, Allan Hollister, had gone into the city for any mail that might be awaiting their arrival at Cologne. Sitting there with the magnificent twin spires of the famous cathedral in plain sight, the others were impatiently awaiting his return.

It may have been ten minutes after the little talk occurred with which this chapter opens that a boy was discovered hurrying toward the boat. From the fact of his wearing a khaki suit like the ones Thad and his other two chums sported, it could be set down for granted that this must be Allan Hollister.

As he drew nearer, all of them could see that his face was grave. This gave Bumpus a new pang, for he feared he would never be able to make the journey across Belgium, and join his invalid mother, who would be waiting for him in Antwerp.

Allan silently handed each of them some mail, but after a glance at his Thad voiced the feelings of his other two allies when he said:

“You’re bringing us bad news, Allan; it’s written on your face, and there’s no use keeping it back any longer. What’s happened?”

Allan was the second in control of the patrol, a good woodsman, and a stout-hearted scout. He braced himself with an effort, and after drawing a big breath went on to tell them the thrilling news he had heard when getting the mail.

“The war is on—German armies have crossed the frontier into Belgium—King Albert has refused to let them pass through his country, and there is a terrible battle being fought at Liége, with thousands of men killed and wounded on both sides. The whole of Germany and Austria have flamed up, and it’s going to be a fight to the death with the biggest nations of Europe on the battle line!”
