Keeping this large view in mind, and recalling, generally, its relations, as remarked briefly in the last chapter, to the configuration of the soil and the effect of this and of other conditions on the plans of the German High Command,[69] we may follow for a few days the story of one unit’s experiences, in order to set these in relation to the Division, the Corps, and the Army. For from the night of January 11th-12th, when the 62nd Division first slept, or tried to sleep—for it was so cold—on French soil, till the Battle of Arras in April, every Battalion in that Division was engaged in the same driving work: in the same work of driving the Germans back, of anticipating their retreat to prepared positions, of consolidating small but important gains, of proving their own worth as a fighting unit, of breaking out, between Thiepval and Hébuterne, to Serre, Puisieux, Miraumont, Achiet, Irles, Pys, always nearer to the Bapaume-Arras road. We may select for this purpose the 2/5th Battalion of the Duke of Wellington’s West Riding Regiment. It was another Battalion of the same Regiment whose fortunes we followed in Chapter II. from its earliest volunteer beginnings, and now, as then, we possess the advantage of consulting a personal diary kept by an Officer of the selected unit.[70] The first thing, where everything seemed strange, was to get to know the way about. A ride to Auxi le Château gave opportunity for a ‘very interesting talk’ with an Officer in the 1/5th Battalion of the same Regiment (49th Division). A day or two later came a tour of the trenches in an old London General omnibus. The party visited Acheux and Warlencourt, and then drove along the Doullens-Arras road, which was closed to traffic at one point owing to shelling. They went through Arras, noticing its damage by fire and incendiary shells, and reached the line held by the 7th East Surreys. Here they had an opportunity of watching the system of relief: the East Surreys by the 6th West Kents. ‘It was a daylight relief and worked out very well indeed.’ The reserve and front-line trenches were examined: the latter were highly complicated; all the Platoon dug-outs were in cellars, owing to the ruined state of the houses and factories; at one point, only twenty-five yards from the German front-line. Patrols went out clothed in white to match the snow. A Company cook-house was blown in by trench-mortar fire, wounding two servants and ruining the breakfast. And so back to Doullens and Bus-les-Artois, rejoining their Battalions. This was in January. On February 3rd, ‘the weather was so cold that the ink in my fountain-pen was frozen.’ On the 7th, ‘the cold was so intense that the oil on the Lewis guns froze.’ On the 13th, a tour in the trenches before Serre, in relief of the 1st Dorsets: ‘the sights one saw in and about the trenches rather opened one’s eyes. The dead, both our own and the enemy, were lying about partially buried; rifles, grenades, unexploded shells, bombs and equipment.
