In the meantime the flank guards had not been idle. The shout of the sentry first attacked had given the alarm to his comrades on either side, and one had started immediately to his aid. The other remained where he was, but levelled his rifle at Shaw and his men as they sprang on to the line. Both were promptly shot down and their rifles and cartridges as promptly secured. By this time the alarm was fairly general. Several shots had been fired, and the line guards up and down the track had come to the conclusion that a serious attack on the line was in progress. Instead of rushing in ones and twos to the point of attack, they now waited until some half-dozen men had collected before advancing. Even these bodies were easily disposed of by the flank guards posted by Shaw. They were well concealed, and, as the Germans came up, opened a heavy fire upon them at close range. Most of the latter dropped at once, and the survivors fled, only too glad to get away in safety with their lives. Max and Dale had assisted in the removal of the rails and their deposit in the muddy ditch. This accomplished, Max, who viewed the whole affair with some misgiving, stood aside and took no part in the further attacks already in progress on the rails. "You look glum, Max," remarked Dale in a rallying tone, as he straightened his back. He himself looked far from glum. His face was flushed, his eyes sparkled, and he bore himself as though at the height of enjoyment. "Don't you like raiding the railway?" "Not this way," replied Max with decision. "What's the good of it? It won't take half an hour to repair, and, coming after that other affair, will mean half the cavalry in the Ardennes stirring on our tracks." "Who cares?" retorted Dale recklessly. "I----What's the matter?" "Hark! A train I think. Let's get to the top of this bit of rising ground and see what happens. The driver can't come steaming through with all that firing going on yonder." The two friends climbed upon the little hill and up into the lower branches of a large tree. The view thus obtained was a wide one, and showed them much. In the distance a train was approaching. It was slowing up as they watched, and presently came to a standstill. Instantly crowds of soldiers poured out from both sides and formed up on the permanent way. Apparently in response to an order, the troops split into two bodies, one passing to the north side of the line and one to the south, both almost immediately disappearing from view in the woods.
