Apart from the losses, the mere fact that a great German army had been hustled across thirty miles of country, had been driven from river to river, and had finally to take refuge in trenches in order to hold their ground, was a great encouragement to the Allies. From that time they felt assured that with anything like equal numbers they had an ascendancy over their opponents. Save in the matter of heavy guns and machine-guns, there was not a single arm in which they did not feel that they were the equals or the superiors. Nor could they forget that this foe, whom they were driving in the open and holding in the trenches, was one who had rushed into the war with men and material all carefully prepared for this day of battle, while their own strength lay in the future. If the present was bright, it would surely be incomparably brighter when the reserves of France and the vast resources of the British Empire were finally brought into line. There had never from the beginning been a doubt of final victory, but from this time on it became less an opinion and more a demonstrable and mathematical certainty.

Why the Marne is one of the great battles of all time.

The battle must also be regarded as a fixed point in military history, since it was the first time since the days of the great Napoleon that a Prussian army had been turned and driven. In three successive wars—against the Danes, the Austrians, and the French—they had lived always in the warm sunshine of success. Now, at last, came the first chill of disaster. Partly from their excellent military qualities, but even more on account of their elaborate and methodical preparations, joined with a want of scruple which allowed them to force a war at the moment when they could take their adversary at a disadvantage, they had established a legend of invincibility. This they left behind them with their cannon and their prisoners between the Marne and the Aisne. It had been feared that free men, trained in liberal and humane methods, could never equal in military efficiency those who had passed through the savage discipline which is the heritage of the methods that first made Prussia great at the expense of her neighbours. This shadow was henceforth for ever lifted from men's minds, and it was shown that the kindly comradeship which exists in the Western armies between officers and men was not incompatible with the finest fighting qualities of which any soldiers are capable.

CHAPTER VI
THE BATTLE OF THE AISNE

The hazardous crossing of the Aisne—Wonderful work of the sappers—The fight for the sugar factory—General advance of the Army—The 4th (Guards) Brigade's difficult task—Cavalry as a mobile reserve—The Sixth Division—Hardships of the Army—German breach of faith—Tâtez toujours—The general position—Attack upon the West Yorks—Counter-attack by Congreve's 18th Brigade—Rheims Cathedral—Spies—The siege and fall of Antwerp.

The hazardous crossing of the Aisne.

The stretch of river which confronted the British Army when they set about the hazardous crossing of the Aisne was about fifteen miles in length. It lay as nearly as possible east and west, so that the advance was from south to north. As the British faced the river the First Army Corps was on the right of their line, together with half the cavalry. In the centre was the Second Corps, on the left the Third Corps, which was still without one of its divisions (the Sixth), but retained, on the other hand, the 19th Brigade, which did not belong to it. Each of these British corps covered a front of, roughly, five miles. Across the broad and swift river a considerable German army with a powerful artillery was waiting to dispute the passage. On the right of the British were the French Fifth and Seventh Armies, and on their left, forming the extremity of the Allied line, was the French Sixth Army, acting in such close co-operation with the British Third Corps in the Soissons region that their guns were often turned upon the same point. This Sixth French Army, with the British Army, may be looked upon as the left wing of the huge Allied line which stretched away with many a curve and bend to the Swiss frontier. During all this hurried retreat from the Marne, it is to be remembered that the Eastern German armies had hardly moved at all. It was their four armies of the right which had swung back like a closing door, the Crown Prince's Fifth Army being the hinge upon which it turned. Now the door had ceased to swing, and one solid barrier presented itself to the Allies. It is probable that the German preponderance of numbers was, for the moment, much lessened or even had ceased to exist, for the losses in battle, the detachments for Russia, and the operations in Belgium had all combined to deplete the German ranks.

The Belgian Army had retired into Antwerp before the fall of Brussels, but they were by no means a force to be disregarded, being fired by that sense of intolerable wrong which is the most formidable stimulant to a virile nation. From the shelter of the Antwerp entrenchments they continually buzzed out against the German lines of communication, and although they were usually beaten back, and were finally pent in, they still added to the great debt of gratitude which the Allies already owed them by holding up a considerable body, two army corps at least, of good troops. On the other hand, the fortress of Maubeuge, on the northern French frontier, which had been invested within a few days of the battle of Mons, had now fallen before the heavy German guns, with the result that at least a corps of troops under Von Zwehl and these same masterful guns were now released for service on the Aisne.
