Whenever she awoke she heard it; and through the dreams which harassed the heavy periods of her stupor of exhaustion which served that night for sleep, that beat of the feet throbbed and throbbed. Ruth reached Montdidier at noon of the next day. It was at Montdidier, accordingly, that she first learned the true magnitude of the disaster and first heard openly spoken what had been said only in part before; and that was that the fate of France and of the allied cause depended now upon the Americans. If they could not quickly arrive in great force and if, having arrived, they proved unable to fight on even terms with the Germans, all was lost. France would not yet give up, in any case; England would hold on; but, without America, they were beaten. And during that day, and through the next, and the next, while Ruth was unable to leave Montdidier, the disaster grew until it was known that the British Fifth Army, as an organized force, had ceased to exist and the Germans, in this single great stroke, had advanced thirty-five miles and claimed the capture of thirteen hundred guns and ninety thousand men. On Monday, as the Germans yet advanced and moved on Montdidier, Ruth was in a column of refugees again; she was obliged to abandon her determined task for the duty of the moment offered to her hands. She got to Compiègne and there was delayed. Roye, Noyon, Montdidier all now were taken; and the wounded from that southern flank of the salient which thrust west toward Amiens were coming back upon Compiègne; and no man yet could say that the disaster was halted. But Foch had come to the command. Ruth had tried to learn from men who had returned from the region where she had left Gerry Hull, what his fate might have been. She knew that he had been flying and fighting again, for she read in one of the bulletins which was being issued, that he had been cited in the orders of the day for Monday; but she learned nothing at all about him after that until the day after the announcement that all allied armies were to be under the supreme command of General Foch. It was Friday, eight days after that first Thursday morning of mist, and surprise, and catastrophe; and still the Germans fought their way forward; but for two days now the French had arrived, and were present in force from Noyon to Moreuil, and for two days the gap between the British and the French, which the German break-through had opened, had been closed.
