It was as if the order had been heard all along the entire front. The bombardment ceased almost abruptly, and rifle and machine-gun fire became audible again. On a colossal scale the effect was that of the throttling down of a powerful motor-car whose engine had been allowed to race. Then, not many moments afterwards, from far away to the eastward there came faint, confused sounds of shouts and cheering. It was the infantry, the long-suffering, tenacious, wonderful infantry charging valiantly into the cold grey dawn along the avenues prepared by the guns.... For Pickersdyke it had been a night of pure joy, unspoilt by any qualms of conscience. He had been welcomed at the battery as a kind of returned wanderer and given a section of guns at once. The major—who feared no man’s wrath, least of all that of a dug-out D.A.C. commander—had promised to back him up if awkward questions were asked. Pickersdyke had only one cause for disappointment—the whole thing had gone too smoothly. He was bursting with technical knowledge, he could have repaired almost any breakdown, and had kept a keen look-out for all ordinary mistakes. But nothing went wrong and no mistakes were made. In this battery the liability of human error had been reduced to a negligible minimum. Pickersdyke had had nothing further to do than to pass orders and see that they were duly received. Nevertheless he had loved every moment of it, for he had come into his own—he was back in the old troop, taking part in a ‘big show.’ As he observed to the major whilst they were drinking hot coffee in the dug-out afterwards: ‘Even if I do get court-martialled for desertion, sir, that last little lot was worth it!’ And he grinned as does a man well pleased with the success of his schemes. To complete his satisfaction, Scupham appeared soon afterwards bringing up a large bundle of kit and a few luxuries in the way of food. It transpired that he had presented himself to the last-joined subaltern of the D.A.C. and had bluffed that perplexed and inexperienced officer into turning out a cart to drive him as far as the battery wagon line, whence he had come up on an ammunition wagon. It was almost daylight when the battery opened fire again, taking its orders by telephone now from the F.O.O.,[9] who was in close touch with the infantry and could see what was happening. The rate of fire was slow at first; then it suddenly quickened, and the range was increased by a hundred yards. Some thirty shells went shrieking on their mission and then another fifty yards were added. The infantry was advancing steadily, and just as steadily, sixty or seventy yards in front of their line, the curtain of protecting shrapnel crept forward after the retiring enemy. At one point the attack was evidently held up for a while; the battery changed to high explosive and worked up to its maximum speed, causing Lorrison to telephone imploring messages for more and still more ammunition....
