And why retire? It was not a question of being defeated, because they were falling back in good order, making sudden halts and delivering violent counter-attacks upon the disconcerted enemy. But his numbers overpowered all resistance. The wave of barbarians reformed itself. The place of each thousand dead was taken by two thousand of the living. And our men retired. One evening, Paul learnt one of the reasons for this retreat from a week-old newspaper; and he was painfully affected by the news. On the 20th of August, Corvigny had been taken by assault, after some hours of bombardment effected under the most inexplicable conditions, whereas the stronghold was believed to be capable of holding out for at least some days, which would have strengthened our operations against the left flank of the Germans. So Corvigny had fallen; and the Château d'Ornequin, doubtless abandoned, as Paul himself hoped, by Jérôme and Rosalie, was now destroyed, pillaged and sacked with the methodical thoroughness which the Huns applied to their work of devastation. On this side, too, the furious horde were crowding precipitately. Those were sinister days, at the end of August, the most tragic days perhaps that France has ever passed through. Paris was threatened, a dozen departments were invaded. Death's icy breath hung over our gallant nation. It was on the morning of one of these days that Paul heard a cheerful voice calling to him from a group of young soldiers behind him: "Paul, Paul! I've got my way at last! Isn't it a stroke of luck?" Those young soldiers were lads who had enlisted voluntarily and been drafted into the regiment; and Paul at once recognized Élisabeth's brother, Bernard d'Andeville. He had no time to think of the attitude which he had best take up. His first impulse would have been to turn away; but Bernard had seized his two hands and was pressing them with an affectionate kindness which showed that the boy knew nothing as yet of the breach between Paul and his wife. "Yes, it's myself, old chap," he declared gaily. "I may call you old chap, mayn't I? It's myself and it takes your breath away, what? You're thinking of a providential meeting, the sort of coincidence one never sees: two brothers-in-law dropping into the same regiment. Well, it's not that: it happened at my express request. I said to the authorities, 'I'm enlisting by way of a duty and pleasure combined,' or words to that effect. 'But, as a crack athlete and a prize-winner in every gymnastic and drill-club I ever joined, I want to be sent to the front straight away and into the same regiment as my brother-in-law, Corporal Paul Delroze.' And, as they couldn't do without my services, they packed me off here. . . . Well? You don't look particularly delighted . . . ?" Paul was hardly listening. He said to himself: "This is the son of Hermine d'Andeville. The boy who is now touching me is the son of the woman who killed . . ."
