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.

      Upon these chief elements Joffre constructed his new plan of campaign. It was first mooted, a few hours after the issue of the order for the general retreat, in the tactical “Note for All the Armies” of August 24, and in the strategical “General Instruction” of August 25. General Headquarters were then housed in the old College, in the small country town of Vitry-le-François. Here, far behind the French centre, undisturbed by the turmoil of the front and the capital, the Commander-in-Chief, aided by such men as General Belin (a great organiser particularly of railway services), General Berthelot and Colonel Pont, grappled with the dire problem and, in the shadow of defeat, imperturbably drafted the design of the ultimate victory.

      The tactical note gathered such of the more urgent lessons of the preceding actions as were capable of immediate application: the importance of close co-operation of infantry and artillery in attack; of artillery preparation of the assault, destruction of enemy machine-guns, immediate entrenchment of a position won, organisation for prolonged resistance, as contrasted with “the enthusiastic offensive”; extended formation in assault; the German method of cavalry patrols immediately supported by infantry, and the need of care not to exhaust the horses. “When a position has been won, the troops should organise it immediately, entrench themselves, and bring up artillery to prevent any new attack by the enemy. The infantry seem to ignore the necessity of organising for a prolonged combat. Throwing forthwith into line numerous and dense units, they expose them immediately to the fire of the enemy, which decimates them, stops short their offensive, and often leaves them at the mercy of a counter-attack.” The Generalissimo offered his lieutenants no rhetorical comfort, but the purge of simple truth. He knew, and insisted on their understanding, that the shrewdest of strategy was useless if faults such as these were to remain uncorrected.

      The “General Instruction No. 2,” issued to the Army Commanders at 10 p.m. on August 25, consisted of twelve articles, which—omitting for the moment the detailed dispositions—contain the following orders:

      “1. The projected offensive manœuvre being impossible of execution, the ulterior operations will be regulated with a view to the reconstitution on our left, by the junction of the 4th and 5th Armies, the British Army, and new forces drawn from the region of the east, of a mass capable of resuming the offensive, while the other armies contain for the necessary time the efforts of the enemy.

      “2. In its retirement, each of the 3rd, 4th, and 5th Armies will take account of the movements of the neighbouring armies, with which it must keep in touch. The movement will be covered by rearguards left in favourable irregularities of the ground, so as to utilise all the obstacles to stop, or at least delay, the march of the enemy by short and violent counter-attacks, of which the artillery will contribute the chief element.
