The main drama, however, quickly unfolded upon the Belgian frontier. Speed and secrecy were vital to the German plans. On July 31, before any declaration of war, and while the German representative at Brussels was perjuring his soul in his country's service by representing that no infringement was possible, three German army corps, the seventh, ninth, and tenth, fully mobilised and highly equipped, were moving up from their quarters so as to be ready for a treacherous pounce upon their little neighbour whom they were pledged to defend. Von Emmich was in command. On the night of Saturday, August 1, the vanguard of the German armies, using motor traffic followed by trains, burst through the neutral Duchy of Luxemburg, and on August 3 they were over the Belgian line at Verviers. The long-meditated crime had been done, and, with loud appeals to God, Germany began her fatal campaign by deliberate perjury and arrogant disdain for treaties. God accepted the appeal, and swiftly showed how the weakest State with absolute right upon its side may bring to naught all the crafty plottings of the strong.
For time was the essence of the situation. For this the innumerable motors, for this the light equipment and the lack of transport. It was on, on, at top speed, that there be no hindrance in the path of the great hosts that soon would be closing up behind. But time was life and death for the French also, with their slower mobilisation, their backward preparation, and their expectations from Great Britain. Time was the precious gift which little Belgium gave to the Allies. She gave them days and days, and every day worth an army corps. The Germans had crossed the Meuse, had taken Vise, and then had rushed at Liége, even as the Japanese had rushed at Port Arthur. With all their military lore, they had not learned the lesson which was taught so clearly in 1904—that a fortress is taken by skill and not by violence alone.
Leman, a great soldier, defended the forts built by Brialmont. Both defender and designer were justified of their work. On August 5 the seventh German Corps attempted to rush the gaps between the forts. These gaps were three miles wide, but were filled with entrenched infantry. The attack was boldly pressed home, but it completely failed. The German loss was considerable. Two other corps were called up, and again on August 7 the attack was renewed, but with no better result. The defenders fought as befitted the descendants of those Belgae whom Caesar pronounced to be the bravest of the Gauls, or of that Walloon Guard which had so great a mediaeval reputation. There were 25,000 in the town and 120,000 outside, but they were still outside at the end of the assault.
Liége, however, had one fatal weakness. Its garrison was far too small to cover the ground. With twelve forts three miles apart it is clear that there were intervals of, roughly, thirty-six miles to be covered, and that a garrison of 25,000 men, when you had deducted the gunners for the forts, hardly left the thinnest skirmish line to cover the ground. So long as the Germans attacked upon a narrow front they could be held. The instant that they spread out there were bound to be places where they could march almost unopposed into the town. This was what occurred. The town was penetrated, but the forts were intact. General Leman, meanwhile, seeing that the town itself was indefensible, had sent the garrison out before the place was surrounded. Many a Belgian soldier fought upon the Yser and helped to turn the tide of that crowning conflict who would have been a prisoner in Germany had it not been for the foresight and the decision of General Leman.
The Germans were in the town upon the 8th, but the forts still held out and the general advance was grievously impeded. Day followed day, and each beyond price to the Allies. Germany had secretly prepared certain monstrous engines of war—one more proof, if proof were needed, that the conflict had been prearranged and deliberately provoked. These were huge cannon of a dimension never before cast—42 centimetres in bore. More mobile and hardly less effective were some smaller howitzers of 28-centimetre calibre said to have come from the Austrian foundries at Skoda. Brialmont, when he erected his concrete and iron cupolas, had not foreseen the Thor's hammer which would be brought to crush them. One after another they were smashed like eggs. The heroic Leman was dug out from under the debris of the last fort and lived to tell of his miraculous escape. Liége was at last in the hands of the invaders. But already the second week of August was at an end—the British were crowding into France, the French line was thickening along the frontier—all was well with the Allies. Little David had left a grievous mark upon Goliath.
The German mobilisation was now complete, and the whole vast host, over a million strong, poured over the frontier. Never was seen such an army, so accurate and scientific in its general conception, so perfect in its detail. Nothing had been omitted from its equipment which the most thorough of nations, after years of careful preparation, could devise. In motor transport, artillery, machine guns, and all the technique of war they were unrivalled. The men themselves were of high heart and grand physique. By some twisted process of reasoning founded upon false information they had been persuaded that this most aggressive and unnecessary of wars was in some way a war of self-defence, for it was put to them that unless they attacked their neighbours now, their neighbours would certainly some day or other attack them. Hence, they were filled with patriotic ardour and a real conviction that they were protecting their beloved Fatherland. One could not but admire their self-sacrificing devotion, though in the dry light of truth and reason they stood forth as the tools of tyranny, the champions of barbarous political reaction and the bullies of Europe. It was an ominous fact that the troops were provided in advance with incendiary discs for the firing of dwellings, which shows that the orgy of destruction and cruelty which disgraced the name of the German Army in Belgium and in the north of France was prearranged by some central force, whose responsibility in this matter can only be described as terrific. They brought the world of Christ back to the days of Odin, and changed a civilised campaign to an inroad of pagan Danes. This wicked central force could only be the Chief Staff of the Army, and in the last instance the Emperor himself. Had Napoleon conducted his campaigns with as little scruple as William II., it can safely be said that Europe as we know it would hardly exist to-day, and the monuments of antiquity and learning would have been wiped from the face of the globe. It is an evil precedent to be expunged from the records for ever—all the more evil because it was practised by a strong nation on a weak one and on a defenceless people by one which had pledged themselves to defend them. That it was in no wise caused by any actions upon the part of the Belgians is clearly proved by the fact that similar atrocities were committed by the German Army the moment they crossed the frontiers both of France and of Poland.
The Allies had more than they expected from Liége. They had less from Namur. The grey-green tide of German invasion had swept the Belgian resistance before it, had flooded into Brussels, and had been dammed for only a very few days by the great frontier fortress, though it was counted as stronger than Liége. The fact was that the Germans had now learned their lesson. Never again would they imagine that the Furor Teutonicus alone could carry a walled city. The fatal guns were brought up again and the forts were crushed with mechanical precision, while the defenders between the forts, after enduring for ten hours a severe shelling, withdrew from their trenches. On August 22 the fortress surrendered, some of General Michel's garrison being taken, but a considerable proportion effecting its retreat with the French Army which had come up to support the town. By the third week of August the remains of the Belgian forces had taken refuge in Antwerp, and the Germans, having made a wide sweep with their right wing through Brussels, were descending in a two-hundred-mile line upon Northern France.
The French plans had in truth been somewhat disarranged by the Belgian resistance, for the chivalrous spirit of the nation would not permit that their gallant friends be unsupported. Fresh dispositions had been made, but the sudden fall of Namur brought them to naught. Before that untoward event the French had won a small but indubitable victory at Dinant, and had advanced their line from Namur on the right to Charleroi on the left. With the fall of Namur their long wall had lost its corner bastion, and they were at once vigorously attacked by all the German armies, who forced the Sambre on August 22, carried Charleroi, and pushed the French back with considerable loss of guns and prisoners along the whole line. There was defeat, but there was nothing in the nature of a rout or of an envelopment. The line fell back fighting tooth and nail, but none the less Northern France was thrown open to the invaders. In this general movement the British forces were involved, and we now turn to a more particular and detailed account of what befell them during these most momentous days.
