Fortunately, the problem of investing Paris while the main French armies remained unbeaten in the field proved to be an insuperable one. The first German task, in accordance with the prophet Clausewitz, was to break the French resistance. Everything would follow after that, and nothing could precede it. Von Kluck, with his army, comprising originally something over 200,000 men, had lost considerably in their conflicts with the British, and were much exhausted by rapid marching, but they were still in good heart, as the roads over which they passed seemed to offer ample evidence that their enemy was in full flight before them. Knowing that they had hit the British hard, they hoped that, for a time at least, they might disregard them, and, accordingly, they ventured to close in, by a flank march, on to the other German armies to the east of them, in order to combine against the main line of French resistance and to make up the gaps of those corps which had been ordered to East Prussia. But the bulldog, though weary and somewhat wounded, was still watching with bloodshot eyes. He now sprang suddenly upon the exposed flank of his enemy and got a grip which held firm for many a day to come. Without going into complicated details of French strategy, which would be outside the scope of this work, it may be generally stated that the whole {144} French line, which had stretched on August 22 from Namur along the line of the Sambre to Charleroi and had retired with considerable loss before the German advance, was now extended in seven separate armies from Verdun to the west of Paris.
