"I fancy if we march behind them with their own loaded rifles we can induce them to go ahead of us to our lines," remarked Roger. "Later on the Germans can be attended to. They won't be very likely to run away." "Say, I guess you've got the right dope!" Jimmy exclaimed. "We'll do just that. But it's late now, and probably as dark as a pocket outside. We can't find our way to the American lines now. Better stay here in the cave until morning." "That's the best thing to do," decided Roger. "If any more spies show up we'll be ready for 'em, though I'm sick of this kind of fighting." "So'm I," agreed Jimmy. They cut into strips some of the German civilians' own garments, and with these bound the two spies. There was no need to gag them, since all danger of any of the plotters giving premature warning was passed. Indeed there seemed to be no need of binding the badly wounded Hun, but Jimmy and Roger were taking no chances. During this process, by the light of the lantern the Khaki Boys made sure of the identity of the Germans. They were the same men who had been seen in the dugout, and there was no question now but what the Bixtons had been the two soldiers seen. Having the instincts of humanity, Roger and Jimmy made their prisoners as comfortable as the circumstances would allow. They took the gags from the mouths of the Bixton brothers and gave them water. But the traitors spoke no word. The lesser wounded German begged for a drink, and it was given to him. The other remained in a stupor, though the Khaki Boys washed the wound on his head and bound it up. Then passed the long night. In the morning, not very much refreshed, as may be imagined, by the weary, hungry hours spent in the cave, Jimmy and Roger ventured forth. They found the entrance by which the Bixtons and the spies had come in, and from this point, which was on a hill, they were afforded a good view of the surrounding country. "There's smoke over there," said Jimmy, pointing to what, at first, seemed to be a fog. "Yes," agreed his companion. "Maybe it's smoke of battle or some burning village. But it means there have been men there, and that's more than can be said of this vicinity. It's deserted." This was true enough. Though there were evidences all about that fighting had gone on in the neighborhood, there was no sign of habitation near the cave, and no inhabitants. "Let's start for that smoke," said Jimmy. "It's an even break that we meet our lines somewhere over that way. That's the logical place for them to be, considering the fighting of yesterday. Let's hike for there, and drive the Bixtons ahead of us." "I'm with you!" cried Roger. There was no necessity of waiting for breakfast--there was no breakfast to be had. Jimmy and Roger donned their underwear, which had dried by this time, and then, again putting on the Bixton's uniforms, the two lads gave their orders.
