"Before the German armies," he says, "became engulfed in the vast depression that stretches from Paris to Verdun, General Joffre with admirable foresight had brought together a powerful army commanded by General Manoury and having as its support the fortified camp of Paris. As soon as General von Kluck, turning momentarily from the road to the French capital and bending his march to the southeast, laid bare his right wing, General Joffre vigorously launched against his flank the entire army of General Manoury. The brilliant offensive of this army achieved success from the beginning; it threw back the German forces. Von Kluck perceived the danger that threatened him, and the danger was serious, for it only required that Manoury should advance a little further and he would have been almost totally defeated. Resolutely, energetically, and with a sang-froid to which homage must be rendered, Von Kluck proceeded to circumvent this danger. He ordered back to the north two of his army corps, recrossed the Marne, and threw himself with intrepidity on Manoury. "But the retreat of these two army corps allowed General French and General Franchet d'Esperey both to drive forward vigorously. Something resembling the phenomenon of a whirlwind then took place in the German ranks. The British army made progress toward the north, the Fifth French Army, commanded by General Franchet d'Esperey, did the same. General Manoury, assisted by all the troops that General Gallieni was able rapidly to put at his disposal, made headway against the furious onslaught of Von Kluck. Thus the entire German right found itself in a most critical situation. It could not overcome Manoury, who was threatening its communications, and on the other hand it found itself powerless to resist the victorious advance of Generals French and de Franchet d'Esperey. "It was the critical moment of the battle. The German General Staff decided that there was only one method of putting an end to it, and that was to direct against the army of General Foch in the center an offensive so violent that the center would be pierced and the French armies cut in two. If this attack succeeded it would free at once the German right and separate into two impotent parts the entire French military force. During the 7th, 8th, and 9th of September the Imperial Prussian Guard directed to the compassing of that end all its energy and courage. All in vain. General Foch not only checked the German onslaught, but drove it back. Thus the French center was not pierced, Von Kluck was not relieved, and he found himself in a position that grew more and more critical. The general retreat of the German armies was the inevitable result. To this decision the German General Staff came, and on the evening of September 9 orders were given to all the armies of the right and center to retire sixty kilometers to the rear. Thus the battle of the Marne was won by the French."
