If you glance through Sir John French's dispatch (at the end of the book) you will see that he had in mind to retire in what is called "echelon" formation. That is, one-half retires and takes up a new position, while the other half stays behind to act as a rear-guard and hold up enemy attacks. Then, in turn, that other half retires behind the first half, and so on. That was the idea, and on the first day it worked very well. But after that it was found simply impossible to keep to it, partly through the enemy's thunderbolt movements, and partly because our men became more and more exhausted. Now, it is also a cardinal principle in rearguard fights that you must not only check your enemy, but must also, whenever possible, make a counter-attack. In fact, the counter-attacks are part and parcel of the checking movements. This is where cavalry comes in very useful. Let us, then, take the three divisions of the Force separately. _The First Corps_ Night attacks, especially in the early morning (it sounds rather Irish), are horribly uncomfortable things. The nerves are continuously on edge and you are apt to loose off guns or rifles at the merest suspicion of a movement. "If ye should see a wee brrown beastie in frront o' ye," a canny Scot sergeant told his men, "ye mauna fire, because likely it'll be a bit rrabbit, and rrabbits are guid for the pot. But if the beastie should walk upon twa legs, then ye may ken it's no a rrabbit, but a Gerrman, an' ye will tak a verry quick but carefu' sicht o' him." All through that Sunday night the men had snatched odd minutes of sleep just where they had fought through the day. And very little rest did the enemy allow them. For one can well imagine how exasperated by this time the enemy were at being held up by a handful of a "contemptible little army." It was most difficult, too, to get any food up to the lines, for the German guns had "registered" all the approaches and persistently dropped their shells across them. But the men hung on cheerily enough, and if they couldn't get any sleep they made up their minds that the Germans should not either, especially where they were dug in only a few hundred yards in front. So the short summer night was passed. And with the first hint of dawn the news ran quickly round that, far from dreaming of retiring, the First Corps was going to attack. The news was as good as a big breakfast. Somehow or other the A.S.C. got up rations to most of the units, and so it was the cheeriest of 2nd Divisions which swung out of their trenches and loop holed houses and headed for the enemy's left flank in Binche. The 1st Division acted as supports.
