Then, on the fifth day, our turn came to act as rear-guard artillery. The horses, tucked away behind a convenient wood when we came into action just before dawn, had an easy morning—and there were many, especially amongst the new-comers received on mobilisation, who were badly in need of it. Now the function of a rear-guard is to gain time, and this we did. But, when at last the order to withdraw was given, our casualties were numerous and the enemy was close. Moreover, his artillery had got our range. The teams issuing from the shelter of their wood had to face a heavy fire, and it was at this juncture that the seasoned horses, the real old stagers, who knew as much about limbering up as most drivers and more than some, set an example to the less experienced ones. Bilfred (and I take him as typical of the rest) seemed with a sudden flash of intuition to realise that his apprenticeship and all his previous training had been arranged expressly that he might bear himself courageously in just such a situation as this. Somehow, in some quite inexplicable fashion, he knew that this was the supreme moment of his career. Regardless of bursting shells and almost without guidance from his driver he galloped straight for his gun, with ears pricked and nostrils dilated, the muscles rippling under his dark coat and his traces taut as bow-strings as he strained at his collar with every thundering stride. He wheeled with precision exactly over the trail eye, checked his pace at the right moment, and ‘squared off’ so as to allow the wheelers to place the limber in position. It was his job, he knew what to do and he did it perfectly. B was the first gun to get away and the only one to do so without a casualty.... More marching, more fighting, day after day, night after night; men were killed and wounded; horses, dropping from utter exhaustion, were cut loose and left where they lay—old friends, some of them, that it tore one’s heart to abandon thus. But there could be no tarrying, the enemy was too close to us for that. Then came the day when the terrible retreat southwards ceased as abruptly and as unexpectedly as it had begun. Rejoicing in an advance which soon developed into a pursuit we forgot our weariness and all the trials and hardships of the past. And I think we forgot, too, in our eagerness, that for the horses there was no difference between the advance and the retirement—the work was as hard, the loads as heavy. For our hopes were high. We knew that the flood of invasion was stemmed at last. We believed that final victory was in sight. Reckless of everything we pushed on, faster and still faster, until our strength was nearly exhausted. It mattered not, we felt; the enemy retreating in disorder before us must be in far worse plight.
