"His hatred of Germany had a concentrated ferocity which I had never seen before... I remember driving with him back to Paris...after he had handed...the German delegates the draft of the Peace Treaty. As we passed the ruins of the palace of St. Cloud, which had been burned by the Germans in 1871, he told me how he remembered seeing the blaze... That event seemed to have burned itself into his memory ... There is only one incident of 1871 of which he spoke to me with emotion, and that was of the poignant scene in the French Assembly when Jules Favre came straight from an interview with Bismarck to report to the deputies the nature of the terms demanded, and the ruthlessness with which the triumphant Chancellor had treated the supplication of the French delegates for some amelioration in the demands. Tears came into M. Clemenceau's eyes—for the first and only time in my intercourse with him—as he described how "the old man" (Favre), in attempting to describe the harshness of the conqueror, broke down in the tribune and wept. I then understood something of M. Clemenceau's hatred of the Germans. They had not only invaded France, defeated her armies, occupied her capital, humbled her pride, but in the hour of victory had treated her with an insolence which for fifty years had rankled in the heart of this fierce old patriot. When I met him at Carlsbad the sore was still stinging him into anger."
