present at this critical moment, and to have met it as our subalterns have so often met large emergencies during the War. The advanced line was held until upon the next day the 60th Brigade, and finally the whole of the Twentieth Division, took over the new positions, which may be regarded as a protective flank line in continuation of that of the Fifty-sixth Division. It should be mentioned that the 61st Brigade of the Twentieth Division had been lent to the Guards during the battle, and had done very sterling and essential work. For a short time the Guards were rested after this splendid but costly service. In the meantime the gallant Sixth Division was left face to face with the hardest problem of all, the Quadrilateral trenches, which, as the name would indicate, were as formidable in the flanks or rear as in front. With a tenacity which was worthy of the traditions of this great division it settled down to the {255} task of clearing its front, meeting with check after check, but carrying on day and night until the thing was done. On the first assault upon September 15, the 1st Leicesters of the 71st Brigade were able to make some progress, but the 8th Bedford of the 16th Brigade, who shared the attack, were completely held up at the starting-point by the terrific fire, while the 1st Buffs had heavy losses in endeavouring to come up to their aid. By about mid-day a mixture of battalions, which numbered about 200 of the York and Lancasters, 50 Buffs and 50 Bedfords, had made their way into the advanced German line, but the Quadrilateral was still intact. The General, seeing the certain losses and uncertain results which must follow from a frontal attack, determined to work round the obstacle, and before evening the 16th Brigade, which had already lost 1200 men, was ready for the advance. The 18th Brigade had gone forward past the Quadrilateral upon the left, working up to the Ginchy-Morval Road, and in close touch with the 1st Scots Guards on the extreme flank of the Guards Division. It now worked down towards the north face of the German stronghold, and in the course of September 16 the 2nd Durham Light Infantry, by a bold advance laid hold of the northern trench of the Quadrilateral down to within a hundred yards of the Ginchy-Morval Road. Here they were relieved by the 1st West Yorks, who took over the task upon the 17th, keeping up constant pressure upon the garrison whose resistance was admirable. These brave men belonged to the One hundred and eighty-fifth German Division. By this time they were isolated, as the British wave had rolled far past them on either side, but their spirit {256} was as high as ever. A second trench to the north of the work was rushed upon September 17 by the Leicesters, who bayoneted fifty Germans in a hand-to-hand conflict. Early in the morning of September 18 came the end, when the British battalions, led by the 1st Shropshire Light Infantry, closed suddenly in and stormed the position.
