Most of the chapters belong to the attacks during the time of siege warfare, for it was by those attacks that the heart was taken out of the enemy. But we must not pass over the marvellous story of how Germany was reduced to a state of beleaguerment, and why she did not succeed in her first plan and win in a war of movement. The reason of this was a great battle, in which France played the chief part, but in which the small British army had also an honourable share. Before we begin our record, then, let us look at the stand on the Marne which wrecked the first hope of a German victory in the war.
Germany, as we have seen, began the war in the West with larger forces than those of France and Britain. She had also prepared definite plans of action, most of which she had managed to conceal from her opponents. General Joffre, the French Commander-in-Chief, was aware of her main intention--to outflank the French left wing by a drive through Belgium; but he did not guess how strong the enemy right wing would be, or how wide its wheel. His own plan was to strike first, and to attack the enemy's left and centre in Lorraine and in the Ardennes, where he supposed the German front would be relatively weak.
He was wrong, for he had under-estimated the number of trained divisions which Germany could place at once in the field. His attacks were repulsed both in Lorraine and in the Ardennes. At the same moment he found that the German right wing, sweeping round through Belgium, was double the strength he had expected. He hurried up troops to meet it, but at Charleroi his Fifth Army was beaten, and the British on its left were compelled to retreat along with it. The result was that on Monday, August 24, 1914, all the armies of the Allies were falling back from the northern frontiers. The men did not know what had happened; but, weary and bewildered, they kept their discipline. That the retirement was achieved without serious losses was a proof of the stoutheartedness of the armies of France and Britain.
Joffre was now compelled to make a new plan. He had to find reserves, and these would take time to collect; he could not get reinforcements brought up to his armies in time, so the armies must fall back to the reinforcements. For nearly a fortnight the retreat went on. Notable exploits were performed by every army, and the record of the retreat from Mons contains the fine defensive battle fought by the British at Le Cateau. The Allies lost heavily in the retirement, but it enabled them to reach their supports, while the enemy had weakened his strength by his long advance. On the 4th September the Allies, who at the start had been outnumbered, were now slightly more numerous than the Germans.
