With the fall of Brussels, the first objective of the Germans may be said to have been gained. But the right wing of Von Kluck's army was still operating northward upon Antwerp. The Belgian army had escaped him within the circle of Antwerp's forts, so that he detailed a force deemed to be sufficient to hold the enemy secure. Then he struck eastward between Antwerp and Brussels at Alost, Ghent, and Bruges. In his advance he swept several divisions of cavalry, also motor cars bearing machine guns. Beyond Bruges his patrol caught their first glimpse of the North Sea, drawing in toward another much-hoped-for goal on the English Channel.
But the Belgian army within security of Antwerp had not been routed. It had retreated in good order, thanks to the resistance of its right-wing rear guard. General de Moranville promptly reenforced it with new volunteers to the extent of some 125,000 men. In addition, he drew upon a fresh supply of ammunition, and new artillery well horsed. His cavalry, however, were certainly no better and probably worse than that with which his army had been complemented originally.
On August 23, 1914, obtaining information that the Germans were in considerably inferior force at Malines, the Belgians began a vigorous counteroffensive. General de Moranville drove the Germans out of Malines on the day following. That was in the nature of a master stroke, for it gave the Belgians control of the shortest railway from Germany into West Flanders. Further, since Von Kluck had reached Bruges, and reenforcements under General von Boehn had passed across the Belgian direct line on Brussels, the great German right wing was in danger of being caught in a trap. Von Boehn, therefore, was hurriedly detached rearward to deal with the Belgian counteroffensive. But this deprived Von Kluck of his needed reenforcements to overcome 2,000 British marines landed at Ostend, that, together with the Civic Guard, had beaten back German patrols from the place. Had the British now landed an army at Ostend, Von Kluck, between the Belgian and British forces, would have been in serious danger of annihilation. With the German right wing thus crumpled, the whole of their offensive would have broken down. But the British did not come, and so the Belgians were left to fight it out single handed. This fighting went on for three weeks, with accurate details lacking. Mainly it was upon the line Aershot-Dyle Valley-Termonde, with Antwerp for the Belgian base.
