Much did, indeed, depend on the result of the morrow, and for the third day, again, it was General von Kluck's initial move that brought disaster to the German side. Why was it that Von Kluck, instead of marching directly on Paris, as would have been expected, made a detour, having as his object not the capital but the French army? It may be said in favor of it that the decision taken by the German General Staff was in conformity with the military doctrine of Napoleon. According to this doctrine, a capital, whatever its importance, is never more than an accessory object, geographical or political. What is of importance is the strategical object. The strategical object is the essential, the geographical object is only accessory. Once the essential object is attained, the accessory object is acquired of itself. Once the French armies had been beaten, thrown back, and dispersed, Von Kluck could return to the capital and take it easily. Conceive of him, on the other hand, attacking the capital with the army of Manoury on his right, which constituted a serious menace to his left, and in front or him the British army and the Fifth French Army; he might have been caught as in a vise between these forces while all his activity was being absorbed by his attack on the intrenchments around Paris. It has been said that if Von Kluck had won the French capital, as it seemed he might, the French could not have gained the Battle of the Marne, and the result of the war might have been very different. It was, however, no mistake on the part of Von Kluck, no false maneuver on his part, that determined the victory of the Marne. Von Kluck did exactly what he ought to have done; the decision taken by the German General Staff was exactly what it ought to have taken, and what was foreseen during the whole course of the war. It was on September 4, 1914, in the morning, that the observations made by the French cavalry, as well as by British aviators and those of the army of Manoury and the military government of Paris, made it clear that the German right (Von Kluck's army) was bending its march toward the southeast in the direction of Meaux and Coulommiers, leaving behind it the road to Paris. At this moment the Fifth French' Army of the left was ready to meet the German forces in a frontal attack, and it was flanked toward the northwest by the British army and by General Manoury's army to the northeast of the capital.
