1,700,000. A later French estimate put the Germans at 1,600,000, with the Allies between 1,400,000 and 1,500,000. The preponderance of efficiency of equipment lay with the Germans.
The plans of the German campaign at this time, so far as they can be determined from the official orders and from the manner in which the respective movements were carried out, were three-fold. The first of these movements was the order given to General von Kluck to swirl his forces to the southeast of Paris, swerving away from the capital in an attempt to cut the communications between it and the Fifth French Army under General d'Espérey. This plan evidently involved a feint attack upon the Sixth French Army under General Manoury (though General Pare took charge of the larger issues of this western campaign), coupled with a swift southerly stroke and an attack upon what was supposed to be the exposed western flank of General d'Espérey's army. The cause of the failure of this attempt was the presence of the British army, as has been shown in the alignment of the armies given above, and as will be shown in detail later, in the recital of the actual progress of the fighting. Important as was this movement, however, it was the least of the three elements in General von Moltke's plan for the shattering of the great defense line of the Allies.
The second element in this plan was, contrary to Germany's usual tactics, the determination to attack the center of the French line and break through. Almost three-quarters of a million men were concentrated on this point. The armies of General von Bülow, General Hausen and the Duke of Württemberg were massed in the center of the line. There, however, General Foch's new Ninth Army was prepared to meet the attack. It will be remembered that, in the disposition of the troops, these respective armies were facing each other across the great desolate plain, the ancient battle ground. If the German center could break through the French center, and if at the same time General von Kluck, commanding the German right, could execute a swift movement to the southeast, the Fifth French Army would be between two fires, together with such part of the Ninth Army as lay to the westward of the point to be pierced. This strategic plan held high promise, and it would have menaced the whole interior of France southward from the plain of Champagne, but even this second part of the plan, important as it was, does not appear to have been the crucial point in the campaign.
The glory of the victory, if indeed victory it should prove, as the successes of the previous two weeks had led the Germans to believe, was to be given to the crown prince. With a great deal of trouble and with far more delay than had been anticipated, the crown prince's army had at last managed to get within striking distance of the forefront of the great battle line. His forces occupied the territory north of Verdun to a southern point not far from Bar-le-Duc. Here the German secret service seems to have been as efficient, as it failed to be with regard to conditions only fifty miles away. General Sarrail's army, which confronted the army of the crown prince, was somewhat weak. It consisted of about two army corps with reserve divisions. Nor could General Joffre send any reenforcements. Every available source of reenforcements had been drawn upon to aid the Sixth Army, encamped upon the banks of the Ourcq, in order that Paris might be well guarded. No troops could be spared from the Fifth and Ninth Armies, which had to bear the brunt of the attack from the German center. General Sarrail, therefore, had to depend on the natural difficulties of the country and to avoid giving battle too readily against the superior forces by which he was confronted. It was a part of the plan of the French generalissimo, however, to feel the strength of the German center, and if it proved that they could be held, to release several divisions and send them to the aid of General Sarrail.
Subordinate to this contemplated attack by the crown prince, yet forming a part of it, and, in a measure, a fourth element in the campaign, was the double effort from the garrisons of Metz and Saarbrücken, combining with the armies of the Bavarian Crown Prince and the forces of General von Heeringen. The Second French Army, therefore, could not come to the aid of the Third, except in desperate need, for it was in the very forefront of the attack on Nancy. If the German left could pierce the French lines at Nancy and pour through the Gap of Lorraine, it would be able to take General Sarrail's army in the rear at Bar-le-Duc, and would thus completely hem it in, at the same time isolating Verdun, which, thus invested in the course of time must fall, forming an invaluable advanced fortress to the German advance.
Battle of the Marne—Situation on September 9, 1914.
Before proceeding to the actual working out of this plan of campaign it may be well to recapitulate it, in order that each development may be clear. The German plan was to pierce the French line at three places, at Meaux, at Bar-le-Duc and at Nancy. General von Kluck, at Meaux, would cut off the Fifth and the Ninth Armies from communication with their base at Paris, the Bavarian Crown Prince would weaken General Sarrail's defense in the rear, and if possible come up behind him, and thus the stage would be set for the great onrush of the Imperial Crown Prince, who, with an almost fresh army, and with a most complete and elaborate system of communications and supplies, should be able to crush the weak point in France's defense, the army under General Sarrail. Such a victory was designed to shed an especial luster upon the crown prince and thus upon the Hohenzollern dynasty, a prestige much needed, for the delays in the advance of the crown prince's army had already given rise to mutterings of discontent. From a strategical point of view the plan was sound and brilliant, the disposition of the forces was excellently contrived, and the very utmost of military skill had been used in bringing matters to a focus.
The French plan, is the next to be considered. From official orders and dispatches and also from the developments of that week, it is clear that General Joffre had perceived the possibility of such a plan as the Germans had actually conceived. He had brought back his armies—and there is nothing harder to handle than a retreating army—step by step over northern France without losing them their morale. The loss of life was fearful, but it never became appalling. The French soldiers had faith in Joffre, even as their faith in France, and, while the Germans had victories to cheer them on, the soldiers of the Allies had to keep up their courage under the perpetual strain of retreat. The administration had evacuated Paris. Everywhere it seemed that the weakness of France was becoming apparent. To the three armies in the field, those commanded severally by General Manoury, Sir John French, and General Lanrezac, the generalissimo steadily sent reenforcements. But he informed the French Government that he was not able to save the capital from a siege. Yet, as after events showed, while these various conditions could not rightly be considered as ruses upon General Joffre's part to lure on the Germans, there is no doubt that he understood and took full advantage of the readiness of the attacking hosts to esteem all these points as prophetic of future victory. The first feature of the French plan, therefore, was to lend color to the German belief that the armies of the Allies were disheartened and thereby to induce the attacking forces to join the issue quickly.
The second part of the French plan lay in General Joffre's decision not to do the expected thing. With General Sarrail placed at the extremest point of danger, it would have been a likely move to transfer the entire British Expeditionary Force from the left wing to the weak point at Bar-le-Duc. There is reason to believe that General von Kluck believed that this had been done.
The third part of the defensive prepared by General Joffre was that of a determination to turn the steady retreat into a counterdrive. Time after time had the other generals implored their leader to give them leave to take the offensive, and on every occasion a shake of the head had been the reply. Sir John French had wondered. But when the French officers found themselves in the region of the Marne, close to the marshes of St. Gond, where in 1814 Napoleon had faced the Russians, they were more content. It was familiar as well as historic ground. Even the youngest officer knew every foot of that ground thoroughly. It was, at the same time, the best point for the forward leap and one of the last points at which a halt could be made.
The fourth part of the plan was the holding fast to the point of Verdun, for thereby the communication of the armies of the Central Powers was seriously weakened. It is to be remembered that this actual fighting army of more than a million men depended for food and for ammunition supplies upon the routes from Belgium and Luxemburg by way of Mézières and Montmédy, and the circuitous line to Brussels via St. Quentin. Had Maubeuge fallen a little earlier the situation of the Central Powers would have been less difficult, and both commissariat and ammunition
