"Nothing," growled the prisoner.
"That doesn"t go with me," replied Frank. "I happened to hear some of that speech of yours and Coblenz was sprinkled through it rather thickly. Suppose you hand over to me that map with the red dots marked on it."
"I have no map," the man replied, a look of apprehension coming into his eyes.
"Lying again, are you?" said Frank. "Bart, cover this fellow with your rifle while Billy goes through his pockets."
The prisoner"s fist clenched, but a prod of Bart"s rifle made him think better of it, and Billy drew from one of the inside pockets of the man"s coat the identical map over which the group had been poring when Bart first came upon the scene.
"That"ll do," said Frank. "Go back to the wall and sit down. Your case will be attended to by the American authorities at Coblenz."
The German, with a muttered imprecation, did as he was told, and while Bart kept his eye on the group of prisoners, Frank and the other Army Boys looked over the map.
They had been so long in Coblenz that they knew the town from end to end, and could readily identify the places that on the map were splashed with red. They included all the places occupied as headquarters by staffs of the various brigades and divisions of the American Army, as well as the American hospital and other buildings devoted to army uses.
"What do the red marks mean, do you think?" asked Billy, with lively curiosity.
"Blood or bombs or something of that kind, I suppose," replied Frank. "Taking this with what I gathered from the fellow"s speech, I think it marks places that are to be blown up. It looks like a general uprising against American rule. I think that Army headquarters will find this little sheet of paper an interesting thing to study. And it wouldn"t surprise me very much if our genial friend over there should find himself before long standing before a firing squad."
"What is this place here?" asked Tom, putting his finger on one of the red spots.
"I don"t know of any government building there," commented Billy.
Frank took another look.
"Why, fellows," he said with quickening interest, "that"s where the alley is that we were so nearly trapped in the other night.
Don"t you recognize it?"
"Sure enough," agreed Billy. "But what is there that they would want to blow up?"
"Maybe some of these red spots are meant to indicate meeting places of the conspirators," suggested Frank. "See, there"s a little red cross added here that you don"t find in connection with the army and government buildings. But it"s queer that that alley should turn up again. I wish I knew what it meant."
"Well, we"ll have to let the Secret Service ferret that out," said Billy. "They have fellows there to whom this will be as clear as crystal after they"ve studied it a little. In the meantime we"ve got a big enough job on our hands to take care of these prisoners.
What are we going to do with them?"
"We"ve got time to think that over between now and daylight,"
answered Frank. "For the present we"ll make them lie down flat and far enough apart so that they can"t talk with each other. Then you and I will stand the first watch and Bart and Tom the next. As soon as daylight comes we must be on the move."
The plan was carried out, although Bart and Tom declared that they had lost all desire for sleep and would keep awake with the others. Frank, however, wanted to have them in good shape when morning came, and the plan was carried out. As a matter of fact, Bart and Tom were fast asleep in five minutes, and Frank and Billy yielded as readily when their turn came.
With the first streak of dawn, the boys were on their feet.
"Doped it out yet?" Bart asked of Frank.
"Pretty well," his chum answered. "I"ve figured out that we"d do better to try to find our detachment than to go back with these fellows to Coblenz. In the first place, it must be nearer, and then, too, we have the chance of meeting some of the detachment who have probably been sent out to look for us. The sun will give us the general direction and we"ll probably hit the camp before long."
"Perhaps some of the prisoners could give us the direction,"
suggested Bart.
"I suppose most any of them could," answered Frank. "Some of them, no doubt, are natives of this section, though that big red beard comes from Berlin. But do you think I"d trust any of them? Not on your life! They"d only lead us into a trap."
"I guess you"re right," agreed Bart.
"How about breakfast for these Huns?" asked Tom.
"We"ll have to rustle some grub for them, of course," answered Frank. "Haven"t they got any food with them?"
"A few hunks of bread and cheese," answered Tom, "but not nearly enough to go around. We"ll have to give them some of our rations, I suppose, though we made quite a hole in them last night and there isn"t very much left."
"Well, we"ll divide up with them as long as we have any," said Frank, "though I know mighty well they wouldn"t do it with us if the case were reversed."
"You bet they wouldn"t," answered Tom, "I"ve been a prisoner in their hands, and I know what I"m talking about."
They made coffee and distributed food, giving to their prisoners as much as they ate themselves. Then Frank lined up the prisoners and directed them to go ahead in the general direction he pointed out, warning them sternly that he would not hesitate to shoot at the least sign of resistance or any attempt to escape.
The storm had ceased, although a bitter wind was still blowing and heaping the snow in drifts. Still this had some advantages, for while it piled the snow deep in places it swept other spots almost clean and they made fairly rapid progress. The prisoners marched sulkily but steadily, with a wholesome respect for the rifles behind them and the men who held them.
They had been marching for perhaps an hour through the bleak forest, when Bart gave a sudden exclamation.
"See those black dots on the snow?" he said, pointing ahead and a little to the right. "They"re moving and they"re coming this way!
I"ll bet it"s some of our fellows sent out to find us."
Frank looked hard and long, and as he looked his face grew grave.
He did not seem to share his comrade"s jubilation.
"Guess again, Bart," he said.
"Why?" asked Bart.
"Because," replied Frank, "those fellows are wearing German uniforms. They"re probably a lot of disbanded soldiers on their way home. I rather think, boys, that we"re in for a fight."
CHAPTER VII
A CLOSE CALL
There was a stir among the Army Boys as they crowded around their leader.
"Are you sure, Frank?" asked Billy.
"Positive," answered Frank. "I can tell by their uniform and by their walk. I could even make out that some of them were wearing the uniform of the Jaeger regiments. They fought against us in the Argonne, and you"ll remember that they"re pretty tough birds. If it comes to a sc.r.a.p we"ll have our work cut out for us."
"But why should there be any sc.r.a.p?" questioned Tom. "Germans are arrested every day in Coblenz and no one tries to rescue them."
"That"s different," replied Frank. "The people know there that we"ve got powerful forces right at hand that could crush any attempt at rescue. But that doesn"t count much out in the wilderness. If these fellows have an officer with them, he"ll probably have sense enough to know that it doesn"t pay to buck up against the United States army. But if they"re just traveling along without organization, they feel so sore at us that they may be willing to take a chance and mix in."
"How many do you make them out to be?" asked Billy.
