But he had no time for musing, and after a moment's glance he turned and burrowed deeper into the woods. There alone for the moment lay safety. In those leafy coverts he could lie concealed, while he took breath and thought out the situation.

He had no idea of where the American lines lay. Bound hand and foot as he had been during that terrible journey, and tortured by the thoughts that had a.s.sailed him, he had taken little note of the way he was traveling. And even if he had, he could not have told with certainty what was the dividing line between the hostile armies.

All that he could do was to exercise the utmost caution, get as deeply into the recesses of the wood as he could, and let his future course be guided by circ.u.mstances. In a battle area that was so full of soldiers it would not be long before he would catch sight of some of them. The great thing was to see them before they saw him. If they wore German helmets he would keep his distance. If, on the contrary, he should see the old familiar khaki uniform of his American comrades, his troubles would be over.

But if the most important thing was concealment, another problem almost as important was the question of food. He had had only the scantiest kind of nourishment since his escape from the prison yard. The last crumb had been eaten that morning. He had no weapon of any kind with which to shoot squirrels or rabbits or birds. And he did not dare to approach a cottage for fear that he might again be placed in the power of his enemies.

But he was not yet starving, though exceedingly hungry, and he kept on in the woods, intent upon putting as many miles behind him as possible before he stopped for rest.

Far up in the wooded hills he came in sight of a little cabin. It was a dilapidated little shack that perhaps had been used by hunting parties in happier days. It seemed to be entirely deserted, but he was wary and lay in the bushes for an hour or more, watching it closely for any sign of life. Only when he felt perfectly sure that there was no one about, did he creep up to the door and look in.

He drew a sigh of relief when he saw that it was indeed uninhabited.

Not only that, but there was no evidence that any one had visited it of late. There was no sign of a path and the bushes had grown up close to the door. One of the hinges of the door had rusted away and the door sagged heavily upon the other.

There was absolutely nothing in the hut except a rough board table and a three-legged stool. Tom searched about eagerly in the hope that he might find some food left by its last occupants. He was not particular, and even mouldy crusts would have been eagerly welcomed.

But even in this he was doomed to be disappointed.

Still it was something to be under a roof. Human beings once had been there, and the fact seemed to bring him in contact with his kind. And even this rough shelter was better than being compelled to sleep in the woods. If he had only had something to still the terrible gnawing at his stomach he would have been content--at least as far as he could be contented while a fugitive, with his life and liberty in constant danger.

After he had rested a while he went outside, with the double purpose of watching for enemies and trying to find something to eat. He fashioned a club from a stout branch and made several attempts to get a squirrel or a bird by hurling it at them. But the weapon was too clumsy and they were too quick, and this forlorn hope came to nothing. So that when night at last dropped down upon him he was more hungry than ever and had to go to sleep supperless.

The next morning he was more fortunate, for he came upon a stream that abounded in fish. He improvised a hook and line and landed several fair-sized ones. He had some matches in an oilskin pouch, and he made a little fire in a deep depression, so as to hide the smoke, and roasted fish over it. He had no salt, but never had a meal tasted more delicious in his life.

Now a burden was lifted from his mind. At least he would not starve.

Fish, no doubt, would grow wearisome as a diet if it were varied with nothing else. But at least it would sustain life and give him strength for the tasks that lay before him.

He listened for the booming of the guns and tried to figure out from the sound just where the contending armies were facing each other.

Sometimes they grew louder and fiercer, and at other times seemed to recede, as the tide of battle ebbed and flowed. But there was rarely any lull in the ominous thunder, and Tom knew that the fiercest kind of fighting was going on. He thought of Frank and Bart and Billy, who he felt sure were in the very thick of it, and he grew desperate at the thought that he was not at their side, facing the same dangers, and, as he hoped, sharing in the same victories.

Gradually he worked his way down the mountain, taking the utmost care to avoid detection, until he felt sure from the increasing din that he was not far from one or the other of the hostile armies. But it was of the utmost importance to him to know whether he was within the German or the American lines.

The question was solved for him when, some days later, he caught sight of a file of German soldiers pa.s.sing through a ravine a little way below him. These were followed by others. He sought shelter instantly upon catching his first glimpse of them, but the bushes were thin at that point, and a huge tree seemed to offer a more secure refuge. He climbed it quickly, and, peering through the leaves, tried to figure out the situation. Rank after rank pa.s.sed, and seemed to be taking up a position with the view of making an attack. Batteries were drawn up, and their guns pointed in a direction away from where Tom was hiding.

This was a valuable, but at the same time a painful, bit of information, because it showed Tom that he was behind the German lines instead of in front of them. If he had been in front, it would be simply a matter of making his way in all haste to where the American armies lay. Now he knew that in order to reach his own lines he would have to cross through the German positions. And without weapons this could only be a forlorn hope. Even had he been armed it would have been a desperate chance.

He was pondering this fact with a sinking of the heart, when suddenly he saw approaching a man in American uniform. What could it mean? The man was not a prisoner, or he would have been under guard. Yet what other explanation was there for the appearance of the uniform in the midst of the Germans, who swarmed all about?

The man came nearer, until he paused beneath the tree. He looked about as though expecting to see some one. Then he glanced at the watch on his wrist, and uttered an exclamation of impatience. It was evident that he had made an appointment, and that the other party to the tryst was slow in coming.

The day was warm, and the upward climb through the woods had been arduous. The man took his hat from his head and wiped his forehead with his handkerchief. As he did so, Tom caught his first glimpse of the newcomer's face, and his heart gave a leap of surprise as well as repulsion when he recognized Nick Rabig.

The last news that Tom had had of Rabig was that he had been taken prisoner in the preceding Fall. He had not known, of course, of Nick's alleged escape from German captivity, and of his return to the American lines, but his quick mind readily reached the correct conclusion. He had always distrusted Rabig and had felt sure that the fellow was at heart a traitor. He was morally certain that the German corporal, whom Nick had been a.s.signed to guard, had escaped with Rabig's connivance, and he remembered what Frank had told him about hearing Rabig's voice in the woods the night the German spy was shot. But Rabig's cunning, or perhaps his luck, had prevented his treachery being proved.

Whatever errand had brought Rabig to this spot, Tom felt sure that it boded no good to the American cause, and even in the precarious position in which he found himself he rejoiced at the thought that he might be instrumental in unmasking a traitor.

While these thoughts were pa.s.sing through his mind, a German officer approached from another direction. He saw Rabig, and hastened toward him. He greeted Nick coldly, and with an air that scarcely concealed the contempt he felt for the man whose services he was using.

An animated colloquy began at once. But unluckily for Tom it was in German. He hated the language, but just then he would have given anything if he could have understood what was pa.s.sing between the two men.

The conversation continued for some time. Rabig handed over some papers which the German officer carefully looked over, using a pencil to follow some lines that seemed to be the tracing of a map or plan.

Then he folded them up and put them carefully in his pocket, and after a few more sentences had been exchanged Tom heard the clink of money and saw Rabig tuck something away in his belt. Then the officer stood up and with a curt nod went away toward the bottom of the hill.

For some minutes more Rabig remained sitting at the foot of the tree.

Then he took money from his belt and counted it carefully. Tom couldn't help wondering whether it consisted of thirty pieces of silver!

In Tom's mind a plan was rapidly forming. He looked through the trees in every direction. No one was in sight. From the slope below came the hum of the camp, but no helmets were visible.

If Rabig had come through the German lines he had done so by means of a pa.s.s. That pa.s.s would take him back just as it had brought him through. He must have it in his pocket now.

Tom measured the distance between himself and the figure sitting beneath him. Then with the litheness of a panther he dropped plump on Rabig's shoulders.

The shock was terrific and knocked the breath from the traitor's body.

He rolled over and over. Tom himself was thrown forward on his hands and knees, but the next moment he had risen and his hands fastened like a vise around Rabig's throat.

CHAPTER XXI

CROSSING THE LINE

Nick Rabig was a young man of powerful build, and under ordinary conditions Tom would have had his work cut out for him. But the surprise and the shock had taken all the fight out of the traitor, and Tom's sinewy hands never relaxed until Rabig's face was purple and he lay limp and gasping. Then Tom improvised a gag and thrust it into the rascal's mouth and rapidly bound his hands and feet.

When he had the miscreant helpless, Tom rose panting to his feet and looked about him. There was no sign that the struggle had attracted attention. Rabig himself had had no time to utter a cry for help.

The renegade had revived sufficiently now to understand what had happened, and his face was a study of conflicting emotions. Rage and hate and fear showed in his features. He recognized Tom, and he knew that his treachery stood discovered. He knew that with the evidence against him he was doomed to stand before a firing squad if he should be taken into the American lines.

Tom looked at him as one might look at a leper.

"You low-down traitor!" he said bitterly. "You vile scoundrel! I've caught you at last and caught you dead to rights. You're the most contemptible thing that breathes. You're a disgrace to your uniform.

You ought to be wearing a wooden overcoat and you will when Uncle Sam lays his hands on you. I ought to kill you myself this minute."

His hand clenched the pistol which he had taken from Rabig's pocket, and a look of craven fear came into the traitor's eyes.

"Oh, don't be afraid," said Tom scornfully. "I'm not going to do it.

Perhaps you'll suffer more if I let you live than if I killed you.

You're a marked and branded man. You're a man without a country. The very men you've sold yourself to look upon you as a yellow dog.

"Now, Rabig, listen to me," Tom went on with deadly earnestness. "I'm going to strip you of the uniform you've disgraced. I'll have to untie your hands for a minute to get the coat over your arms, but I've got the drop on you and if you make the slightest move except to do what I tell you to you're a dead man."

Rabig was too cowed to do anything but obey, and in a few minutes Tom had stripped him of coat and trousers and put them on himself. He re-bound Rabig's hands tightly. Then he went through the pockets of the coat.

As he had expected he found the pa.s.s that had admitted Rabig to the German lines. Opposite the word "_Losung_," which Tom knew meant "countersign," was scribbled the word "Potsdam."

"I guess this thing that brought you over will take me back," Tom remarked. "Now, Rabig, I'm going to leave you here with your German friends. They'll pick you up after a while, though I don't care whether they do or not. I'm going back to the boys of the old Thirty-seventh and tell them just what has happened to Nick Rabig, the traitor. So long, Benedict Arnold."

With a parting glance of contempt Tom left the traitor and went down the hill with a confidence that he was very far from feeling.

He had the pa.s.s and the countersign, but he was not sure that these would be sufficient. Perhaps an officer would be called by the sentry to make sure that everything was all right. Perhaps the sentry at the point where he should try to pa.s.s the line might be the same one who had let Rabig through, and he might notice the difference in personal appearance. Any one of a dozen things might happen to arouse suspicion.
