The consequences, however, to the men of this decision in favour of continual retirement were severe. The 1st Corps did not reach Landrecies till ten o'clock at night. They had been upon the move for eighteen hours; but even so, the enemy, in that avalanche of advance (which was possible to him, as we now know, by the organization of mechanical transport), was well in touch. The Guards in Landrecies itself (the 4th Brigade) were attacked by the advance body of the 9th German Army Corps, which came on in overwhelming numbers right into the buildings of the town, debouching from the wood to the north under cover of the darkness. Their effort was unsuccessful. They did not succeed in piercing or even in decisively confusing the British line at this point; and, packed in the rather narrow street of Landrecies, the enemy suffered losses equivalent to a battalion in that desperate night fighting. But though the enemy here failed to achieve his purpose, his action compelled the continued retreat of men who were almost at the limit of exhaustion, and who had now been marching and fighting for the better part of twenty-four hours. In that same darkness the 1st Division, under Sir Douglas Haig, was heavily engaged south-east of Maroilles. They obtained ultimately the aid of two French reserve divisions which lay upon the right of the British line, and extricated themselves from the peril they were in before dawn. By daylight this 1st Corps was still continuing its retirement in the direction of Wassigny, with Guise as its objective. [Illustration: Sketch 56.] Meanwhile the 2nd Corps, which had not been so heavily attacked, and which lay to the west--that is, still upon the extreme of the line--had come, before the sunset of that Tuesday, the 25th, into a line stretching from Le Cateau to near Caudry, and thence prolonged by the 4th Division towards Seranvillers. [Illustration: Sketch 57.] It will be seen that this line was bent--its left refused. This disposition was, of course, designed to meet the ceaseless German attempt to outflank on the west; and with the dawn of Wednesday, the 26th, it was already apparent how serious would be the task before this 2nd Corps, which covered all the rest of the army, and, in a sense, the whole of the Anglo-French retirement. General Sir Horace Smith-Dorrien, who was here in command, was threatened with a disaster that might carry in its train disaster to the whole British contingent, and ultimately, perhaps, to the whole Franco-British line.
