The Battle of the Marne

by G. H. Perris

That he and his Staff were caught both unprepared and ill-prepared gives an impish touch of satire to this passage. That it is, nevertheless, the authentic voice of Joffre is confirmed by one of his rare personal declarations in the course of the war. This statement was made in February 1915—when many of the commanders referred to had been removed, and the officership of the French Army considerably rejuvenated—to an old friend[30] who asked him whether Charleroi was lost under pressure of overwhelming numbers. “That is absolutely wrong,” replied Joffre. “We ought to have won the battle of Charleroi; we ought to have won ten times out of eleven. We lost it through our own faults. Faults of command. Before the war broke out, I had already noted that, among our generals, many were worn out. Some had appeared to me to be incapable, not good enough for their work. Some inspired me with doubt, others with disquietude. I had made up my mind to rejuvenate our chief commands; and I should have done so in spite of all the commentaries and against any malevolence. But the war came too soon. And, besides, there were other generals in whom I had faith, and who have not responded to my hopes. The man of war reveals himself more in war than in studies, and the quickest intelligence and the most complete knowledge are of little avail if they are unaccompanied by qualities of action. The responsibilities of war are such that, even in the men of merit, their best faculties may be paralysed. That is what happened to some of my chiefs. Their worth turned out to be below the mark. I had to remedy these defects. Some of these generals were my best comrades. But, if I love my friends much, I love France more. I relieved them of their posts. I did this in the same way as I ought to be treated myself, if it be thought I am not good enough. I did not do this to punish them, but simply as a measure of public safety. I did it with a heavy heart.”

Such were the character and record of the man upon whom, at the darkest moment in modern history, fell the burden of the destinies of liberal Europe; who was called upon to prove, against his own words, that a great leader must and can improvise something essential of what has not been prepared; who, between August 23 and 25, 1914, in a maze of preoccupations, had to provide the Western Allies with a second new plan of campaign. Some day his officers will tell the story of how he did it, of the outer scene at his shifting headquarters during those alarming hours, as the Emperor’s Marshals portrayed their chief pacing like a caged tiger by candlelight in a Polish hut, or gazing gloomily from the Kremlin battlements upon the flames that were turning his ambition to ashes. Joffre will not help us to such pictures; and in this, too, he shows himself to be representative of the modern process, which is anything but picturesque. If he had none of the romance of the stark adventurer about him, he had a cool head and a stout heart; and we may imagine that, out of the depths of a secretive nature, there surged up spontaneously in this crisis all that was worthiest in it, the stored strength of a Spartan life, the will of a deep patriotism, the lessons of a long, varied, pondered experience. So far from dire peril paralysing his faculties, it was now that they first shone to the full. Calm, confident, clear, prompt, he set himself to correct the most glaring errors, and to create the conditions of an equal struggle. We know from his published Army Orders what resulted. Castlenau, Pau, Foch were far away on the east, or at the centre. There were other advisers; but, in the main, this was Joffre’s own plan.

Before we state it, and trace its later modification, it will be well to recall the main features of the problem to be solved.

II. The Second New Plan

The first fact which had to be reckoned with was that the main weight of the enemy was bearing down across the north and north-east, and was, for the moment, irresistible. Retreat, at the outset, was not, then, within the plan, but a condition of it. There was no choice; contact with the invader must be broken if any liberty of action was to be won back. Defeat and confusion had been suffered at so many points, the force of the German offensive was so markedly superior, that an unprepared arrest on the Belgian frontier would have risked the armies being divided, enveloped, and destroyed piecemeal.

If the first stage of the retreat was enforced, its extension was in some measure willed and constantly controlled. For all the decisions taken, Joffre must have the chief credit, as he had the whole responsibility. The abandonment of large tracts of national territory to a ruthless enemy cannot be an easy choice, especially when the inhabitants are unwarned, and the mind of the nation is wholly unprepared (the defeats on the Sambre and the Meuse were not known for several days to the civil public, and then only very vaguely). A less cool mind might have fallen into temporising expedients. Maubeuge was to hold out for a fortnight more; the 4th Army had checked the enemy, and Ruffey had repulsed several attacks; Longwy had not yet capitulated. But the Commander-in-Chief was not deceived. He had no sooner learned the weight of Kluck’s flying wing than he realised that the only hope now lay in a rapid retirement. The fact that the British force, holding the west flank, depended upon coast communications for its munitions, supplies, and reinforcements, was an element to be counted. In every respect, unreadiness in the north dominated the situation.

Evidently the retreat must be stayed, and the reaction begun, at the earliest possible moment. Not only were large communities and territories being abandoned: the chief German line of attack seemed to be aimed direct at the capital, which was in a peculiar degree the centre of the national life. This consideration, which no Commander-in-Chief could have forgotten, was emphasised in a letter addressed at 5 a.m. on August 25 by the Minister of War, M. Messimy, to General Joffre. It contained a specific order from the Government—probably the only ministerial interference with the operations in this period—thus phrased: “If victory does not crown a success of our armies, and if the armies are compelled to retreat, an army of at least three active corps must be directed to the entrenched camp of Paris to assure its protection.” In an accompanying letter, the Minister added: “It goes without saying that the line of retreat should be quite other, and should cover the centre and the south of France. We are resolved to struggle to the last and without mercy.”[31] No doubt, these measures would, to Joffre, seem to “go without saying.” The retreat, so long as necessary, must be directed toward the centre of the country, and at the same time the capital must be protected.

There was another necessity of no less importance. The retreat must be covered on the east. After the reverse of Morhange–Sarrebourg, this was a continual source of anxiety. On August 25, the German Armies of Lorraine, now reinforced, were hammering at the circle of hills called the Grand Couronné of Nancy, and were upon the Moselle before the Gap of Charmes. Belfort and Epinal were safe, and Verdun was not yet directly threatened. Very little consideration of the rectangular battle front—the main masses ranged along the north, while a line of positions naturally and artificially strong favoured the French on the east—would lead to the further conclusion: to stand fast along the east, as cover for the retreat from the north. Castelnau and Dubail, therefore, were asked to hold their critical positions at any cost. At the same time, Mulhouse and the northern Vosges passes were abandoned; Belfort, Epinal, and even Verdun were deprived of every superfluous man, in order to meet the main flood of invasion. The evacuation of Verdun and Nancy was envisaged as a possibility. The line Toul–Epinal–Belfort could not be lost without disaster.

Such were the three chief conditions affecting the extent of the strategic retreat. Conditions are, however, to be made, not only suffered; and General Joffre had no sooner got the retreat in hand than he set himself to the constitution of a new mass of manœuvre by means of which, when a favourable conjuncture of circumstances should be obtained, the movement could be reversed. The simultaneous disengagement and parallel withdrawal of four armies, with various minor forces, over a field 120 miles wide and of a like depth, was an operation unprecedented in the history of war. The pains and difficulties of such a retreat, the danger of dislocation and demoralisation, are evident. Its great compensation was to bring the defence nearer to its reserves and bases of supply, while constantly stretching the enemy’s line, and so weakening his striking force. This could not, of course, be pure gain: the French and British Armies lost heavily on the road south by the capture of laggards, sick, wounded, and groups gone astray, as well as in killed and men taken in action. The Germans lost more heavily in several, perhaps in most, of the important engagements, and they were much exhausted when the crucial moment came. On the other hand, the Allies were constantly picking up reinforcements; while the enemy had to leave behind an army of occupation in Belgium, and large numbers of men to reduce Maubeuge, to garrison towns like Lille, Valenciennes, Amiens, St. Quentin, Cambrai, Laon, Rethel, Rheims, to terrorise scores of smaller places, and to provide guards and transport for ever-lengthening lines of communication.
