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. "But on September 3d, the intelligence service, which was working perfectly, stated, about the middle of the day, that the German columns, after heading straight for Paris, were swerving toward the southeast and seemed to wish to avoid the fortified camp. "General Gallieni and I then had one of those long conferences which denoted grave events; they usually lasted from two to five minutes at most. The fact is that the military government of Paris did little talking--it acted. The conference reached this conclusion: 'If they do not come to us, we will go to them with all the force we can muster.' Nothing remained but to make the necessary preparations. The first thing to do was not to give the alarm to the enemy. General Manoury's army immediately received orders to lie low and avoid any engagement that was not absolutely necessary." Then care was taken to reinforce it by every means. All was ready at the designated time.
