The capture of one made the capture of the two others comparatively easy. It was only necessary to await a moment when the farther sentinel was facing away from the next man marked down for attack, before springing upon him. One after the other the three guards were successfully placed out of action, and the stern work of reprisal was at hand. As a precautionary measure, two men, wearing the tunics and helmets of the captured Germans, were stationed as sentries one at each end of the break, to satisfy their German neighbours in case they should miss the sight of the comrades who had gone. Then rapidly Max selected two pairs of rails, one pair on the up-line and one on the down-line, and the dozen great spanners were quickly at work. Certain of the nuts of the rails and of some of the chairs were carefully loosened a little, and everything was made ready to shift one end of each rail as soon as the signal should be given. Then the men withdrew once more to the obscurity of the bushes. Having satisfied himself that everything was in readiness, Max settled himself to watch the trains as they passed, and to seize upon the essential moment. Trains were now running less frequently than at every hour in the twenty-four, and in the comparative silence he could tell when a train was approaching while it was yet some miles away. It was his intention to await the almost simultaneous approach of two trains from opposite directions, and in steady patience he waited. His men did not know the full extent of his plans and were impatient to see the result of their--to them--successful labours. They could not understand this halt, and grumbled under their breath at the strange hesitancy of their young leader. But everything had gone so well under his guidance that none of them dared to express his discontent aloud, and Max was left to put the finishing touch upon his plans in peace. Suddenly his ear caught the sounds he had been awaiting. "Forward!" he commanded in an undertone in two languages. The men sprang quickly on to the lines and wrestled with the nuts and bolts with all their might. In a very short space of time the rails were loose at one end and the chairs removed. Then Max gave the word for all four rails to be levered inwards, towards the centre of the track, until the loose ends were a foot out of line with the other rails. The chairs were then roughly refixed at the extreme ends of the sleepers, and the bent rails bolted as firmly as possible in their new positions. While this was being done the four rails next the gaps were unbolted and entirely removed. When all was done there was a break 40 feet long in each track, and the pair of rails on the side from which the trains were approaching had been bent inwards, and now pointed towards the corresponding pair on the other track, thus:-- [Illustration]
