Next morning, Monday, September 7, 1914, another glorious summer morning, saw a resumption of the battle along exactly the same lines, with the same persistent attack and defense along the eastern part of the front, and with the British making full use of the blunder made by the German right. General von Kluck had realized his plight, but, even so, he had not secured an understanding of the size of the force that was threatening his flank, and he sent as a reenforcement a single army corps which had been intrenched near Coulommiers on the Grand Morin. The British had three full army corps and were well supplied with cavalry and artillery. Yet Coulommiers was Von Kluck's headquarters and actually, when the Germans were driven back and the British troops entered the town, Prince Eitel, the second son of the kaiser; General von Kluck and his staff were compelled to run down to their motor cars and escape at top speed along the road to Rebais, leaving their half-eaten breakfast on the table, and their glasses of wine half emptied. One of the most dramatic cavalry actions of this period of the war took place shortly before noon, when one hundred and seventeen squadrons of cavalry were engaged. In this action the British were successful, but the German cavalry were tired and harassed, having been severely handled the day before. In this engagement between the British and the German right, all the odds had been in favor of the British, and success meant merely the grasping at opportunities that presented themselves. Still, by constantly striking at General von Kluck's exposed flank, his frontal attack of General d'Esperey was so weakened, that, toward evening at the close of two days of continuous and very severe fighting, the Fifth French Army was able to advance and hold the position from La Ferte-Gaucher to Esternay. The ground gained was valuable but not essential, yet it made a profound impression. General d'Esperey's step forward was the Germans' step back. It meant that the road to Paris was barred. How fully this was realized may be seen from an order signed by Lieutenant General Tuelff von Tschepe und Weidenbach and found in the house that had been occupied by the staff of the Eighth German Army Corps when the victorious French entered Vitry-le-Francois. The order was dated "September 7, 10:30 p. m." and it read as follows: "The object of our long and arduous marches has been achieved. The principal French troops have been forced to accept battle, after having been continually forced back. The great decision is undoubtedly at hand. To-morrow, therefore, the whole strength of the German army, as well as all that of our Army Corps, are bound to be engaged all along the line from Paris to Verdun. To save the welfare and the honor of Germany I expect every officer and man, notwithstanding the hard and heroic fights of the last few days, to do his duty unswervingly and to the last breath. Everything depends on the result of to-morrow."
