summer day he stayed there, waiting for the night. As soon as it was dark he wriggled back to our trenches, tumbled over the parapet of the front-line trench, and narrowly escaped falling on the point of a bayonet. But he never forgets the feeling of perfect safety and peace at being back, even in an exposed trench, with friends. The fields across which we rode had been ploughed the preceding autumn by the French civilians. Later, when the snow had disappeared, we could see where the ground had been torn up by the horses of a German riding-school of ten days before. On some of the roads the ruts and heavy marks of the retreating German transports could still be seen. It was a new and exciting experience to ride along a road which only two or three days before had been traversed by the Germans in a retreat, even though they called it a "retirement." The thought was very pleasant to men who, for the last two years, had been sitting _in front_ of the Boche month after month, and who, even in an attack, had been unable to find traces of foot, hoof, or wheel mark because of the all-effacing shell-fire. Here and there were places where the Boche had had his watering-troughs, and also the traces of scattered huts and tents on the ground where the grass, of a yellowish green, still showed. The front line of defence here was really no front line at all, but was merely held as in open warfare by outposts, sentry groups, and patrols. At night it was the easiest thing in the world to lose one's self close up to the line and wander into the German trenches. In fact, over the whole of this country, where every landmark had been destroyed and where owing to the weather the roads were little different from the soil on each side, a man could lose himself and find no person or any sign to give him his direction. The usual guide which one might derive from the Verey lights going up between the lines was here non-existent, as both sides kept extremely quiet. Even the guns were comparatively noiseless in these days, and were a man to find himself at night alone upon this ground, which lay between two and three miles behind our own lines, the only thing he could do would be to lie down and wait for the dawn to show him the direction. As we rode toward O---- our only guide was a few white houses two or three miles away on the edge of the village. The German had not evacuated O---- of his own free will, but a certain "Fighting Division" had taken the village two days before and driven the German out, when he retired three or four hundred yards farther to his rear Hindenburg Line. The probable reason why he hung on to this village, which was really in front of his line of advance, was because at the time he decided to retire on the Somme, the Hindenburg Line was incomplete. In fact, the Boche could still be seen working on his wire and trenches.
