The weather is still favourable to the enemy in his plan of withdrawal. Yesterday there was over all the battlefields such a solid fog, after a night of frost which condensed the earth's moisture, that one could not see fifty yards ahead. Our airmen, if they had thought it worth while mounting, would have stared down into this white mist and seen nothing else. Our gunners had to fire "off the map" at a time when direct observation would have been most valuable. I do not remember to have seen anything so uncanny on this front as the effect of our men moving in this heavy wet darkness like legions of shadows looming up in a grey way, and then blotted out. The fog clung to them, dripped from the rims of their steel helmets, made their breath like steam. The shaggy coats of horses and mules plastered with heavy streaks of mud were all damp with little beads of moisture as white as hoar-frost.
Nothing so far in this German movement has been sensational except the fact itself. Fantastic stories about gas-shells, battles, and great slaughter in the capture of the enemy's positions are merely conjured up by people who know nothing of the truth.
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.
