Battalions, brigades, and divisions went into the fight, were worn down in more or in less time, precisely as the chances of the ground either screened or exposed them for a while to the fire-blasts. Sometimes it was only a matter of hours before what had been a brigade ceased to exist--had soaked horribly into the ground. The wastage was brought down and back across the shell-holes as well as might be, losses were made good, and with a half, two thirds, or three quarters, new drafts, the original Battalion climbed back to its task. While some development behind the next fold of land was in progress or brought to a standstill, they would be concerned only with the life-and-death geography of the few hundred yards immediately about them, or those few score yards over which profitable advances could be made. A day, even an hour, later, the use and value of their own hollow or ridge might be altogether abolished. What had been a hardly won foothold would become the very pivot of a central attack, or subside into a sheltered haven of refuge, as the next dominating ridge or lap of the large-boned French landscape was cleared. Equally suddenly, even while the men thanked God for their respite, German batteries or a suddenly pushed-forth chain of German machine-guns would pound or spray their shelter into exposed torment once more. As one philosopher of that unearthly epoch put it some time afterwards: “We was like fleas in a blanket, ye’ll understand, seein’ no more than the next nearest wrinkle. But Jerry and our Generals, ye’ll understand, they kept us hoppin’.”
