As we could be of no assistance to the distressful Henry we continued our own search, and, by hailing all within call, eventually reached our trench, where we found the colonel, always in good mood when something practical wanted doing, superintending Headquarters' occupation of the place. "Major Mallaby-Kelby, the doctor, the adjutant, and myself can fix up under here," he said, pointing to a large tarpaulin fastened across the trench. "The signallers have got the mined dug-out round the corner, and you," he went on, referring to me, "had better start fixing Wilde and yourself up. We'll make that gun-pit with the camouflaged roofing into a mess to-morrow." With the aid of the servants I gathered six long two-inch planks, and placed them across the part of the trench that seemed best protected from enemy shells. A spare trench cover pulled full stretch on top of these planks lent additional immunity from rain. A little shovelling to level the bottom of the trench, and Wilde's servant and mine laid out our valises. A heap of German wicker ammunition-carriers, sorted out on the ground, served as a rough kind of mattress for the colonel. The doctor had fastened upon a spare stretcher. In half an hour we were all seeking sleep. Zero hour was at 1 A.M., a most unusual time for the infantry to launch an attack. But this would increase the element of surprise, and the state of the moon favoured the enterprise. When hundreds of guns started their thunder I got up to see, and found the doctor on the top of the trench also. Bursts of flame leapt up all around, and for miles to right and left of us. The noise was deafening. When one has viewed scores of modern artillery barrages one's impressions become routine impressions, so to speak; but the night, and the hundreds and hundreds of vivid jumping flashes, made this 1 A.M. barrage seem the most tremendous, most violently terrible of my experience. The doctor, looking a bit chilled, gazed long and solemnly at the spectacle, and for once his national gift of expressing his feelings failed him. When news of the results of the operation came to us it was of a surprising character. The infantry had moved forward under cover of the barrage, had reached their first objective, and continued their advance two miles without encountering opposition. The Boche had stolen away before our guns loosed off their fury. I only saw three prisoners brought in, and some one tried to calculate the thousands of pounds worth of ammunition wasted on the "barrage." A message came that we were to hold ourselves in readiness to rejoin our own Divisional Artillery; our companion Field Artillery Brigade, the --rd, would march also. At 6.30 P.M. the orders arrived. We were to trek northwards, about four thousand yards as the crow flies, and be in touch with our C.R.A. early next morning.
