The most important of these natural features, however, is of less consequence than the strategical gain of a front whereon the French wings were both safe, while the German wings were both threatened. Gallieni, in throwing the 6th Army upon Kluck’s flank, did but anticipate the inevitable by one or two days. What happened arose necessarily out of the strategy of the retreat, in the direction and form of which Joffre never lost his initiative. It is possible that, had he retired farther, the victory might have been more complete. Actually, the five German armies were drawn within a hemicycle 200 miles wide and 30 miles deep. Their right could not help passing before Maunoury, or their left before Sarrail, except by refusing battle. They dare not turn aside; but the penalty of going on was to offer two cheeks to the smiter. There is, however, no trace of hesitation. The common soldiers still thought they were advancing “Nach Paris.” At Headquarters, the tactic of envelopment having failed, everything was risked on a converging attack upon the French centre. IV. THE LAST SUMMONS We can now enter upon the details of the titanic encounter with a clear impression of its general character. As soon as the relation of forces was realised, the tactical purposes dictated by the circumstances to either side were these, and could not be other: for the French, to attack on the wings, especially the western, where there was a promise of surprise, while holding firm at the centre till the pressure there was relieved; for the Germans, to procure a swift decision at the centre, while sufficiently guarding the threatened flanks. But their initiative gave the Allies the benefit of the move: precious hours elapsed ere Kluck could adequately reply. Thus, the disposition of forces governs the whole story of the battle, and gives it a natural unity. It began on the west and developed eastward, as it were, by a series of reverberations, until the shock was returned by Sarrail. In this direction, therefore, we must follow its successive phases. If we speak of a battle of the Ourcq, a battle of St. Gond, and so on, it is only to make what can but be a bird’s-eye view clearer by a just emphasis. These are so many acts in the battle of the Marne, one and indivisible. We have referred above solely to the measurable factors; the moral of the armies will best be seen in the process and the result. But there is a prevision of it in the evenness of the alignment reached on September 5th——much superior to that of the enemy, for some units of the German centre were crowded together, while the Crown Prince’s troops were scattered——and in the readiness of these defeated and weary men for an instant recoil. On the morning of the 6th, the words of the Generalissimo rang out like a bugle-call along the front: “G.H.Q. (Chatillon-sur-Seine), September 6, 7.30 a.m. (telegram 3948).
