Two days later the whole of the band arrived safely within a mile or so of the great main line which runs between Aix-la-Chapelle and Liege, and then on through Namur to Paris. A stoppage to their communications on this line would disconcert the Germans in a way that hardly anything else could do, and Max, from the knowledge he had gained, while at Liege, of the great trains loaded with troops and munitions that constantly passed through at all hours of the day and night, was very well aware of it. Next to his darling scheme for the frustration of the Germans' plans as regards the Durend works, the breaking of the great railway through the town had seemed the most serious blow that could be aimed at the Germans by a few men working independently of the great military forces of the Allies. It was a difficult matter, but not impossible. That was enough. Max and Dale, accompanied by Shaw, reconnoitred the railway after hiding their men well away out of sight. The first point reached Max did not consider suitable, and it was not until they had approached the line at several different places that he found a spot that satisfied him. This spot was one where the line passed along a fairly deep cutting, the sides of which were thickly overgrown with bushes with here and there a young tree. It was a spot at which it would be easy to approach the line unseen. And yet this was not Max's chief reason for selecting it. His design had been to find a spot where the line at night-time would have dark patches of shadow cast upon it here and there. Dale and Corporal Shaw now returned to the spot where the band had been left in hiding, while Max set out for Aix-la-Chapelle alone. He still wore the workman's clothes in which he had masqueraded for so long, and, with his excellent knowledge of the German tongue, he had little to fear so long as he took care not to blunder into a military patrol. Without misadventure he reached Aix, and purchased a dozen spanners similar to those used by plate-layers, except that the handles were short and lacked the great leverage necessary for their work. This difficulty would, however, be easily got over by cutting stout rods from the woods and lashing them to the short spanners. The tools thus obtained would, he knew, be fully suited to the end in view. The reconnoitring of the railway had disclosed the fact that the guards were stationed only about eighty yards apart. Also that they were changed every four hours, at four o'clock, eight o'clock, midnight, and noon. An hour before midnight Max led the band towards the line at the point fixed upon. He had already, at some pains, explained exactly what he desired each man to do, and from their intelligent eagerness felt pretty well assured that they would not fail from want of zeal or knowledge of the part they had to play. To the Frenchmen he, of course, explained matters in their own tongue, and found them equally as ready as their Island brethren.
