The truth is simple and stark. The enemy decided to withdraw, and made his plans to withdraw with careful thought for detail in order to frustrate any preparations we might have made to deal him the famous knock-out blow and in order to save his man-power, not only by escaping this great slaughter which was drawing near upon him as the weeks passed, but by shortening his line and so liberating a number of divisions for offensive and defensive purposes. He timed this strategical withdrawal well. He made use of the hard frost for the movement of men and guns and material, and withdrew the last men from his strongholds on the old line just as the thaw set in, so that the ground lapsed into quagmire more fearful than before the days of the long frost, and pursuit for our men and our guns and our material was doubly difficult. He destroyed what he could not take away, and left very little behind. He fired many of his dug-outs, and left only a few snipers and a few machine-gunners in shell-holes and strong posts to hold up our patrols while the next body of rear-guard outposts fell back behind the barbed wire in front of the series of diagonal trench lines which defend the way to Bapaume. In Gommecourt our troops found only one living man, and he was half dead and quite blind. He had been wounded twenty-four hours previously by a bomb from one of our scouts and had crawled back into a dug-out. It is astounding, but, I believe, quite true, that he knew nothing about the abandonment of Gommecourt, even when it had been achieved. He would not believe it when our men told him. He had lain in his earth-hole wondering at the silence, believing himself deaf as well as blind, except that he could hear the crash of shells. He was frightened because he could hear no movement of his fellow-soldiers. The German scheme is undoubtedly to delay our advance as much as possible and at the cheapest price to himself, so that much time may have elapsed (while his submarines are still at work, and his diplomats, and his propaganda) before we come up to him with all our weight of men and metal upon the real lines to which he is falling back. By belts of barbed wire between the lines of retirement, down past Loupart Wood, and then past Grevillers and Achiet, and outside Bapaume, as well as by strong bodies of picked troops holding on to these positions until the last moment before death or capture or escape, and by massing guns eastward of Bapaume in order to impede our pursuit by long-range fire from his "heavies," and to hold the pivot while his troops swing back in this slow and gradual way, he hopes to make things easy for himself and damnably difficult for us. * * * * * MARCH 12
