His eyes fell on the clock. It had done him good service, but now was of no further use to him. But a second thought made him pick it up and put it in his blouse.

He had no compass, but the clock would do in a pinch. His woodcraft had taught him how the hands of a clock could find for him the cardinal points. More than once his watch in more peaceful times had done him a similar service.

The first thing necessary was to put as wide a distance as possible between himself and the place where he now was. Afterwards he could figure out how to regain his own lines. By ten o'clock at latest his attack on the guard would be discovered. He must be miles away before then, or his life would not be worth a cent.

His impulse was to take the German's gun, but he discarded the thought at once. His only salvation lay in hiding. The gun would count for nothing among the innumerable foes that surrounded him. It was heavy and cumbrous, and would only retard his progress through the woods. He must travel light if he would travel fast.

He gathered up some fragments of food left from the lunch that the guard had been munching and tucked them in his pocket. Then like a shadow he slipped away through the woods.

From what he had seen and bits of information that he had picked up from other prisoners, some of whom were Frenchmen and knew the country well, Tom had a pretty good idea of the lay of the land. He knew that the country was rolling, with here and there a range of hills that rose almost to the dignity of mountains. Here there ought to be plenty of hiding places where he could stay while he planned a way to get across the lines.

Of course his route would be within the German lines for miles. But the inhabitants were in sympathy with the Allied cause, prisoners in almost as great a degree as he himself had been, and he might find among them aid and comfort, though such assistance if discovered would be sure to be visited with hard punishment by the German oppressors.

The way was full of difficulties and almost every step would be attended by danger. But for the present at least he was free. Free! The word had never appealed to him so strongly before. He drew in great draughts of the mountain air. They seemed in a way to cleanse his lungs from the prison taint.

For what seemed to him hours he never slackened his pace. Many times he stumbled in the darkness and his body was full of bruises, but in the joy of his recovered freedom, he scarcely felt the pain. On he went and on until he felt certain he had placed a safe distance between himself and the scene of his recent captivity.

To be sure, the German command had other things to rely on than mere physical pursuit. There were the long arms of the telegraph and telephone, through which every division on the sector might be warned to be on the lookout for him. But it was wholly unlikely that this would be done. On the eve of the great drive, the authorities were too busy to expend their energies on the recapture of an escaped prisoner. Even if he should fall into the hands of another body of his enemies, it was unlikely that they would know anything of his recent exploit.
