For a fortnight the British were on the road and out of the fight, which was left for the most part to Castelnau's 7th and Maud'huy's 10th Armies; and strenuous fighting it was for all-important objects. There was little profit in a British out-march round the German flank in Flanders unless the links between it and the Oise could be maintained, and the Germans were as speedily reinforcing and extending their right as we were preparing to turn it. At first Castelnau seemed to be making rapid and substantial progress; he captured Noyon on 21 September, was pushing on by Lassigny to Roye, and optimistic maps in the English press depicted the German right being bent back to St. Quentin and the French outflanking it as far north-east as Le Catelet. These were not intelligent anticipations. Von Kluck had been reinforced, and a desperate battle ensued from the 25th to the 28th, in which Castelnau was driven back from Noyon and Lassigny. This counter-attack was repulsed with great losses at Quesnoy and Lihons a little farther north, but Maud'huy was not less heavily engaged north of the Somme in a several days' struggle for the Albert plateau. The line established was supposed to run through Combles and Bapaume, and it was not till long afterwards that the public realized how far it had sagged to the westwards, or what that sagging meant when the British had to fight their way up to Bapaume.

North of that watershed the fronts were fluid, if the scattered bodies of French Territorials and German cavalry could be said to constitute a front at all; and there was a strenuous race and struggle to turn the respective flanks. Neither side, it was soon apparent, would succeed in that object, and the practical question was at what point the outflanking contest would reach the coast. The German ambition was to push their right as far south as the mouth of the Seine, while the Allies hoped to thrust their left to the north until it joined the Belgian Army at Antwerp. Maud'huy had entered Arras on 30 September, and some of his Territorials pushed forward to Lille and Douai. During the first three days of October he was fighting hard on the eastern slopes of Vimy Ridge but was compelled to fall back on Arras, while the Germans occupied Lille and Douai and their cavalry penetrated as far as Bailleul, Hazebrouck, and Cassel. But the British from the Aisne were moving up towards their positions on Maud'huy's left, the Aire-La Basse Canal being fixed as the point of their junction, and the 7th Division, with a division of cavalry, had landed at Ostend and Zeebrugge while the Naval Division was sent to assist in the defence of Antwerp. The Allied dream of a front along the Scheldt to Antwerp, barring German access to the sea, seemed on the verge of realization; but dramatic as the moment was, the tension would have been far more acute had men grasped what a difference possession of the Belgian coast was to make in the course of the war.

Success was missed by the Allies because it had been a more urgent task to break the German offensive on the Marne than to save the remnants of Belgian soil and assist the detached Belgian Army; and the whole of our available force had been sent to the vital spot. Isolation is always dubious strategy, but there were sound as well as natural motives behind the decision which led the Belgian Army after the German occupation of Brussels on 20 August to fall back north-westwards on Antwerp instead of southwards to join the Allies at Mons and Charleroi. The isolation did not involve ineffectiveness, and so far away as the Marne the Allies experienced the benefit of Belgian fighting at Antwerp. Three successive sorties alarmed the Germans for the safety of their far-flung right and its communications, and diverted reserves from their front in France to their rear in Belgium (see Map, p. 34). The first began on 24 August and drove the Germans from Malines, while 2000 British marines landed at Ostend. Then the Belgian right stretched out a hand towards the British and captured Alost, while the left struck at Cortenburg on the line between Brussels and Louvain. The communications of the capital were thus threatened on three sides, and the Germans had to recall at least three of their corps from France. It was this interference with their vital plans in France, coupled with the panic produced by the Belgian advance, which provoked the Germans into their barbarities at Louvain, Malines, and Termonde. Schrecklichkeit was to deter the contemptible Belgian Army from spoiling a mighty German success. That was the view of the German staff, and a soldiery prone as ever to pillage and rapine, needed little encouragement to extend to civilians, women, and children the violence which their leaders organized against cathedrals and cities.

Panic produces plots in all countries--in the minds of the panic-stricken, and Germans no doubt believed in the tales of civilian conspiracies which they used to justify their military crimes. Major Von Manteuffel ordered the systematic destruction of Louvain, with its ancient university and magnificent library. The Cathedral and Palais de Justice at Malines were ruined by bombardment after the Belgian troops had left it; and Termonde was burnt because a fine was not paid in time. Massacre, looting, and outrage attained a licence which only the Germans themselves had equalled during the Thirty Years' War. It and other orgies were a natural expression of German militarism; for excessive restraint in one direction provokes relaxation in others, and the tighter the bond of martial law, the less the respect for civil codes. The proverbial licence of soldiery is the reaction against their military discipline.

The second, called "the great sortie" from Antwerp, nearly coincided with the battle of the Marne. It began on 9 September: Termonde was reoccupied, but the main effort was towards Aerschot and Louvain. Aerschot was recaptured on the 9th, though the fiercest struggle took place at Weerde between Malines and Brussels. Kessel, just outside Louvain, was taken on the 10th, but German reinforcements began to arrive on the 11th, and two days later the Belgians were back in their positions on the Nethe, their retirement being marked, as before, by a fresh series of German atrocities. A third sortie induced by representations of the French higher command and by the impression that the German forces before Antwerp had been reduced, was planned for 26-27 September, and some fighting occurred at Alost and Moll. But by this time the new Germany strategy was at work, and the "side-shows" of the first phase of the war became the main objectives of the second. The French Army was fairly secure in its trenches and the way to Paris was barred. But the approach to the Channel ports was not yet closed, and Antwerp was on the way to the Belgian coast. It was a fine city to ransom; its loss might convince the Belgians that there was no hope for their independence; and historical Germans bethought themselves of Napoleon's description of Antwerp as a pistol pointed at England's heart. Its fall would be some consolation for the lack of a second Sedan, and on 28 September the siege began.

The Antwerp defences had been, like those of Lige and Namur, designed by Brialmont, and were begun in 1861. But the rapid growth of the city and the increasing range of guns made Brialmont's ring of forts, which was drawn little more than two miles from the walls, useless as a protection against bombardment, and twenty years later a wider circle of forts, which was barely completed when war broke out, was begun ten miles farther out, beyond the Rupel and the Nethe, and extending almost to Malines. One of the objects of the Belgian sorties had been to keep this ring intact and prevent the German howitzers from being brought up within range of the city. But there are only two means by which forts can be made effective defences; either their artillery must be equal in range and power to that of the attacking force, or the attacking force must be prevented by defending troops from bringing its howitzers within range. Neither of these two conditions was fulfilled. The Belgian trenches, so far as any had been dug, were close under this outer ring of forts, and the German 28-cm. howitzers had an effective range of at least a mile and a half longer than that of any guns the Belgians could mount. These howitzers had already disposed of the fortifications of Lige, Namur, and Maubeuge, and it was only a question of days and hours when they would make a breach in the outer defences of Antwerp.

Their fire was concentrated on Forts Waelhem and Wavre, south and east of Antwerp. Both had been destroyed by 1 October, and the reservoir near the former, which supplied the city with water, was broken down, flooding the Belgian trenches north of the Nethe, beyond which they had now taken refuge. Farther to the left Termonde was seized by German infantry and the Belgians driven across the Scheldt. On the 2nd the Government resolved to leave Antwerp, but its departure and the flight of the civilians were postponed by the arrival of Mr. Churchill, First Lord of the Admiralty, and first a brigade of Royal Marines and then two naval brigades of splendid but raw and ill-armed recruits. They were at once sent out to help the Belgians to defend their trenches along the north bank of the Nethe against the German numbers and their more effective shells. On the 5th and following night both the left and centre of the defence were pierced, the Germans crossed the Nethe, and began to concentrate their howitzers on the inner line of ramparts. On the 7th the exodus from the city began by land and water, and amid heartrending scenes a quarter of a million people strove to reach the Dutch frontier or safety on the sea. The Belgian and British troops did their best to hold off the Germans while the flight proceeded and the city was subject to bombardment. It was doubtful whether any would get away, for the Germans had at last begun serious fighting up the Scheldt in order to cut off the retreat towards Zeebrugge and Ostend. In the narrow gap between the intruding Germans and the Dutch frontier some were forced across the latter and interned; others fell into the enemy's hands; and less than a third of the first Naval Brigade escaped to England. On the 9th the bombardment ceased, and on the 10th the Germans made their formal entry into a well-nigh deserted city. They had got their pistol pointed at the heart of England, but like Napoleon they learnt that it was a pistol which could only be fired by sea-power.

Most of the Belgian Army with the remnants of the British forces got away to the coast through the gap beyond the Scheldt which Von Beseler had failed to close in time; and it is impossible to say whether the gallant efforts of the Royal Marines and naval brigades did more to facilitate this escape than the postponement of the retreat, caused by their arrival, did to frustrate it. As an end in itself the expedition for the relief of Antwerp was a failure; but it was designed to subserve a larger operation, the scope of which has not yet been revealed. At the time of its dispatch there may still have been hopes for the success of Joffre's larger strategical scheme of bending back the German flank in Flanders behind the Scheldt; and obviously, if the failure of the Germans at the Marne and a successful defence of Antwerp by the Entente should induce the Dutch to intervene, the German position in the West would be completely turned. In either case "other and more powerful considerations," as the Admiralty expressed it on 17 October, prevented the "large operation" of which the expedition of the Naval Division had been merely a part, from being carried out; and the "powerful consideration" may have been the forces which Germany was massing at Aix and in Belgium to defeat the Entente strategy in Flanders.

The fall of Antwerp was as fatal to our scheme of controlling the Scheldt as Castlenau's and Maud'huy's successful defence between the Oise and Arras had been to the German project of reaching the mouth of the Seine; and it still remained to be seen at what point the expanding pressure upon the opposing flanks would impinge upon the coast. Neither side had yet reconciled itself to or perhaps conceived of such a stalemate to their strategy. Rawlinson's 7th Division of infantry and 3rd of cavalry had not been landed at Zeebrugge and Ostend on 6 October to defend those ports or even the Yser, and the fresh German armies advancing through Belgium were not intended to waste their strength on the ridges in front of Ypres or floods around Dixmude. The Germans hoped, if not to turn the Entente flank, at least to seize Dunkirk, Calais, and Boulogne; and Joffre and French were planning to make La Basse, Lille, and Menin the pivot of a turning movement which should liberate Brussels, isolate Von Beseler in Antwerp, and threaten the rear of the German position along the Aisne. To render these plans feasible it was necessary that La Basse and Lille should be held and that the indefinite German flank in Flanders should be outreached; and thus the country from Arras northwards to the coast became the ground on which the autumn campaign in the West was doomed to be decided.
