Parallel to this, at a distance ranging from one to two miles, was a new line through Rocquigny, Bapaume, and Ablainzevelle, almost equally strong and elaborate. Behind it, as every one understood, was a thing called the Hindenburg Line, known to the Germans as “Siegfried”--a forty-mile marvel of considered defences with branches and spurs and switches, one end of which lay on St. Quentin and the other outside Arras. This could be dealt with later, but, meantime, the enemy in the Arras-Le Transloy salient were uneasy. The attacks delivered on selected positions; the little inter-related operations that stole a few hundred yards of trench or half a village at a leap, or carried a gun-group to a position whence our batteries could peer out and punish; above all, the cold knowledge that sooner or later our unimaginative, unmilitary infantry would shamble after the guns, made them think well of lines in their rear to which they could retire at leisure. Verdun had not fallen; very many of their men lay dead outside its obliterated forts, and so very many living were needed to make good the daily drain of the Somme that they had none too many to spare for Austrian or Turkish needs. Their one energetic ally was the weather, which, with almost comic regularity, gave them time after each reverse to draw breath, position more guns, reorganise reliefs, and explain to their doubting public in Germany the excellence and the method of their army’s plans for the future. The battle of the Ancre, for instance, was followed by an absolute deadlock of six weeks, when our armies--one cannot assault and dig out battalions at the same time--dropped everything to fight the mud, while our front-line wallowed in bottomless trenches where subalterns took from three to six hours to visit their posts on a front of one quarter of a mile. Bitter frosts set in with the first weeks of the New Year and the “small operations” began at once, on our side, round such portions of the Beaumont-Hamel heights as the enemy still clung to. Here the Third, Seventh, and Eleventh Divisions fought, shift by shift, for the rest of January and won the high ground needed for our guns to uncover against Serre and Grandcourt, which were the keys of the positions at the corner of the Arras-Le Transloy salient. Thanks to our air-work, and the almost daily improvement in the power and precision of our barrages, that little army came through its campaign without too heavy losses, and still further cramped the enemy’s foothold along the Ancre, while the rest of the line enjoyed as much peace as the Somme allowed them when “there was nothing doing.” MARKING TIME
