CHAPTER III.
THE TURN AT THE MARNE.
Germany, as we have seen, began the war in the West with larger forces than those of France and Britain. She had also prepared definite plans of action, most of which she had managed to conceal from her opponents. General Joffre, the French Commander-in-Chief, was aware of her main intention—to outflank the French left wing by a drive through Belgium; but he did not guess how strong the enemy right wing would be, or how wide its wheel. His own plan was to strike first, and to attack the enemy's left and centre in Lorraine and in the Ardennes, where he supposed the German front would be relatively weak.
He was wrong, for he had under-estimated the number of trained divisions which Germany could place at once in the field. His attacks were repulsed both in Lorraine and in the Ardennes. At the same moment he found that the German right wing, sweeping round through Belgium, was double the strength he had expected. He hurried up troops to meet it, but at Charleroi his Fifth Army was beaten, and the British on its left were compelled to retreat along with it. The result was that on Monday, August 24, 1914, all the armies of the Allies were falling back from the northern frontiers. The men did not know what had happened; but, weary and bewildered, they kept their discipline. That the retirement was achieved without serious losses was a proof of the stoutheartedness of the armies of France and Britain.
Joffre was now compelled to make a new plan. He had to find reserves, and these would take time to collect; he could not get reinforcements brought up to his armies in time, so the armies must fall back to the reinforcements. For nearly a fortnight the retreat went on. Notable exploits were performed by every army, and the record of the retreat from Mons contains the fine defensive battle fought by the British at Le Cateau. The Allies lost heavily in the retirement, but it enabled them to reach their supports, while the enemy had weakened his strength by his long advance. On the 4th September the Allies, who at the start had been outnumbered, were now slightly more numerous than the Germans.
On that day, the 4th September, Joffre halted the retreat. He was now ready to turn and strike back. The enemy forces lay in a huge arc 200 miles wide and 30 deep—from the eastern skirts of Paris to Verdun. On the German right was Kluck, who had led the great wheel through Belgium, and next to him in order towards the east were the armies under Bülow, Hausen, the Duke of Wurtemberg, and the Imperial Crown Prince. Beyond the Meuse lay the detached German left wing, under the Crown Prince of Bavaria, threatening Nancy. The German plan was for Kluck to turn the left, and Prince Rupprecht of Bavaria the right, of the French line, while their centre broke the French centre in Champagne.
FIELD-MARSHAL SIR JOHN FRENCH
(EARL OF YPRES).
The Allies had been forced into a difficult position. From the south of the Marne their line extended to Verdun, consisting of the British Army under Sir John French, and the armies of Franchet d'Esperey, Foch, Langle de Gary, and Sarrail; while facing the Bavarians at Nancy were the armies of Castelnau and Dubail. In the meantime a new French army, the Sixth, had been formed, and this, under Maunoury, lay on the extreme left, covering Paris, and was thus in a position to threaten Kluck's right flank and rear. Joffre's new plan was to strike hard with his left, on the flank of the invader, and for this purpose he had gravely thinned the rest of his front so as to strengthen the forces of Maunoury and Franchet d'Esperey. It was a great hazard, for if the Bavarians forced the gate of Nancy the French right would be turned, and if the German centre broke through the weak French centre the battle would be lost, whatever happened on the French left.
It was one of the moments of crisis on which the world's history depends. The captains who were to win the war for the Allies were all in the field—Foch with an army, Haig with a corps, Pétain and Mangin and Allenby with divisions. Joffre told his men that on the coming fight depended the salvation of their country, and every private in the ranks felt the gravity of the hour. France was fighting on the old ground where, long centuries before, the Hun invasion had been rolled back by Theodoric the Visigoth, and the spirit of her men was kindled to a flame.
The First Battle of the Marne was won not, as many believed, by any single exploit, but by the faithful performance of its duty by each section of the long-drawn line. Let us look first at the French right flank in Lorraine. There the battle began on the 4th September, and three days later came the crisis when, by the slenderest margin, the enemy failed to break Castelnau on the ridge called the Grand-Couronné. The Kaiser himself was a spectator of the fight, for Germany had counted on forcing the pass; but by the 8th she had failed, and by the 9th Castelnau had firmly barred the gate.
The French centre, under Foch, Langle de Gary, and Sarrail, had a longer period of trial. Sarrail, at Verdun, was all but broken on the 8th, and was compelled to fall back to the west bank of the Meuse. All through the 9th and 10th the desperate struggle continued, and by the evening of the last day the French general was preparing for retreat. Suddenly, however, he found the attack ebbing, and by the 12th the enemy was mysteriously withdrawing. Farther west Langle de Gary had his worst moment on the 8th; on the 9th he received reinforcements which eased his position, and on the 10th he too felt the strange weakening of the enemy. The left centre under Foch had the sternest fight of all. He had against him the bulk of Bülow's and Hausen's armies, and on the 8th he found his flanks turned and his whole front split into gaps. Nevertheless he prepared to attack on the 9th with his last ounce of strength. All that day his centre and right were falling back before the enemy's thrust, but he still persevered in his purpose and marched the single division he could muster to the point where he thought he could strike with the greatest effect. The blow was never delivered, for on the evening of the 9th the apparently triumphant advance halted and ebbed. Like Sarrail and Langle de Gary, Foch, having resisted to the limit of human endurance, discovered that the enemy was miraculously disappearing.
The cause of the miracle was the doings of the French left wing. Joffre had hurled Maunoury on Kluck's flank and rear, while Sir John French and Franchet d'Esperey attacked in front. Kluck met the threat with vigour and resolution. He formed front to flank, as the phrase goes—that is, he faced round to what had been his wing—and in the three days' fighting all but defeated Maunoury. On the night of the 7th the outflanking French left found itself outflanked in turn, and its attack turned into a desperate defence. But on the 9th came salvation. Kluck's manoeuvre had left a gap of 30 miles between himself and Bülow, and into this gap were pouring the British force and that of Franchet d'Esperey. Suddenly Maunoury discovered that certain villages in front of him were evacuated, and his airmen told him of enemy convoys moving to the north. At 1 p.m. that day Bülow began his retreat, and Kluck was forced to follow suit. Sir John French and Franchet d'Esperey had pierced the enemy front, and the retreat of the German right caused the retreat of all the German armies. They fell back to a line along the Aisne, through Champagne, and down the east bank of the Meuse—a strong line, which for four years was never really broken. But, none the less, it was a retreat.
The First Battle of the Marne may well rank as the greatest, because the most critical, contest of the war. It was decisive in the sense that it defeated Germany's first plan of campaign. She had hoped for a "battle without a morrow"; but the battle had been fought and the morrow was come. She was now compelled to accept the slow war of entrenchments, and to see every week bringing her nearer to the condition of a beleaguered city. The immediate cause of victory was Maunoury's flank attack, which opened the way for the British and Franchet d'Esperey. But without the daring strategy of Foch and the stubborn endurance of Langle de Gary and Sarrail—above all, without Castelnau's epic resistance at Nancy—the chance in the West could
