On the 11th the French crossed the Marne between Tours-sur-Marne and Sarry, driving the Germans in front of them in disorder. On the 12th they were in contact with the enemy to the north of the Camp de Chalons. The reserve army of the center, acting on the right of the one just referred to, had been intrusted with the mission during the 7th, 8th, and 9th of disengaging its neighbor, and it was only on the 10th that being reinforced by an army corps from the east, it was able to make its action effectively felt. On the 11th the Germans retired. But, perceiving their danger, they fought desperately, with enormous expenditure of projectiles, behind strong intrenchments. On the 12th the result had none the less been attained, and the two French center armies were solidly established on the ground gained.
To the right of these two armies were three others. They had orders to cover themselves to the north and to debouch toward the west on the flank of the enemy, which was operating to the west of the Argonne. But a wide interval in which the Germans were in force separated them from the French center. The attack took place, nevertheless, with very brilliant success for the French artillery, which destroyed eleven batteries of the Sixteenth German army corps.
On the 10th inst., the Eighth and Fifteenth German army corps counter-attacked, but were repulsed. On the 11th French progress continued with new successes, and on the 12th the French were able to face round toward the north in expectation of the near and inevitable retreat of the enemy, which, in fact, took place from the 13th.
The withdrawal of the mass of the German force involved also that of the left. From the 12th onward the forces of the enemy operating between Nancy and the Vosges retreated in a hurry before the two French armies of the East, which immediately occupied the positions that the enemy had evacuated. The offensive of the French right had thus prepared and consolidated in the most useful way the result secured by the left and center.
Such was this seven days' battle, in which more than two millions of men were engaged. Each army gained ground step by step, opening the road to its neighbor, supported at once by it, taking in flank the adversary which the day before it had attacked in front, the efforts of one articulating closely with those of the other, a perfect unity of intention and method animating the supreme command.
To give this victory all its meaning it is necessary to add that it was gained by troops which for two weeks had been retreating, and which, when the order for the offensive was given, were found to be as ardent as on the first day. It has also to be said that these troops had to meet the whole Germany army. Under their pressure the German retreat at certain times had the appearance of a rout.
In spite of the fatigue of the poilus, in spite of the power of the German heavy artillery, the French took colors, guns, mitrailleuses, shells, and thousands of prisoners. One German corps lost almost the whole of its artillery.
In that great battle the spectacular rush of General Gallieni's army defending Paris, was one of the dramatic surprises that decided the issue. In that stroke Gallieni sent his entire force forty miles to attack the right wing of the German army. In this gigantic maneuver every motor car in Paris was utilized, and the flying force of Gallieni became the "Army in Taxicabs," a name that will live as long as France exists.
General Clergerie, Chief of Staff to Gallieni told the story for posterity. He said:
"From August 26, 1914, the German armies had been descending upon Paris by forced marches. On September 1st they were only three days' march from the advanced line of the intrenched camp, which the garrison were laboring desperately to put into condition for defense. It was necessary to cover with trenches a circuit of 110 miles, install siege guns, assure the coming of supplies for them over narrow-gauge railways, assemble the food and provisions of all kinds necessary for a city of 4,000,000 inhabitants.
