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._
