For several days now I have been going with our advancing troops into towns, villages, and country abandoned by the enemy in his retreat. It has been a strange adventure, fantastic as a dream, yet with the tragedy of reality. The fantasy is in crossing over No Man's Land into the German lines, getting through his wire, and passing through trenches inhabited by his soldiers until a day or two ago, travelling over roads and fields down which his guns and transport went, and going into streets and houses in which there are signs of his recent occupation. He has ruined all his roads, opening vast craters in them, and broken all his bridges, but our men have been wonderfully quick in making a way over these gaps, and this morning I motored over the German trenches at Roye, zigzagging over this maze of ditches and dug-outs by bridges of planks before getting to the roads behind his line. After passing the area of shell-fire on our side and his, the field of shell-craters, the smashed barns and houses and churches, the tattered tree-trunks, the wide belts of barbed wire, one comes to country where grass grows again, and where the fields are smooth and rolling, and where the woods will be clothed with foliage when spring comes to the world again--country strange and beautiful to a man like myself, who has been wandering through all the filth and frightfulness of the Somme battlefields. German sentry-boxes still stand at the cross-roads. German notice-boards stare at one from cottage walls, or where the villages begin. Thousands of coils of barbed wire lie about in heaps, for the enemy relied a great deal upon this means of defence, and in many places are piles of shells which he has not removed. Gun-pits and machine-gun emplacements, screens to hide his roads from view, observation-posts built in tall trees, remain as signs of his military life a mile or two back from his front lines, but behind the trenches are the towns and villages in which he had his rest billets, and it is in these places that one sees the spirit and temper of the men whom we are fighting. The enemy has spared nothing on the way of his retreat. He has destroyed every village in his abandonment with a systematic and detailed destruction. Not only in Bapaume and in Péronne has he blown up, or burnt, all the houses which were untouched by shell-fire, but in scores of villages he has laid waste the cottages of the peasants, and all their farms and all their orchards. At Réthonvillers this morning, to name only one village out of many, I saw how each house was marked with a white cross before it was gutted with fire. The Cross of Christ was used to mark the work of the Devil.
