Some of the Americans were so eager to keep close on the heels of the retreating Huns that they did not stop long enough thoroughly to clean up machine gun nests and other strong points. Groups of the Boche hid until the main body of the Americans had passed on, then raked them from the rear with machine gun and rifle fire, snipers concealed in trees being particularly annoying in this way.
In scores of instances our men found machine guns and their gunners both tied fast in trees, so that neither could fall, even when the operator was shot. It was reported reliably but unofficially that machine gun nests had been found where the Germans, in the short time they had been on the ground, had arranged aerial tramways of rope from tree to tree, so that if a machine gun nest were discovered in one tree and the gunners shot, the guns could be slid over to another tree on the ropes and another group of men could set them going again.
Many of the Huns "played dead" until the American rush was past, then opened fire on the rear. This is an old trick, but Allied soldiers who tried it early in the war discovered that the Germans countered it by having men come along after a charging body of troops, bayoneting everybody on the field to make sure all were dead. The Germans, however, knew they were safe in trying it with our men, for they were well aware Americans did not bayonet wounded men or dead bodies.
Sergeant McFadden, who has been mentioned before, was making his way through the woods with a single companion when he noticed an apparently dead Boche in a rifle pit. He got a glimpse of the face, however, and noticed the eyes were closed so tightly the man was "squinting" from the effort. McFadden jabbed his bayonet in the German's leg, whereupon he leaped to his feet and seized the rifle from the astonished American's hand. He threw it up to fire, but before he could pull the trigger, McFadden's companion shot him.
At one point, below Fossoy, the Germans not only went back to the river, but actually crossed it in the face of the 110th Infantry's advance. Reaching the banks of the river, however, the enemy was within the protection of his big guns, which immediately laid down such fire that it was utterly impossible for the Americans and French to remain. Having had a real taste of triumph, the Pennsylvanians were loath to let go, but fell back slowly, unpressed by the Germans, to their former positions.
