The result was that when the Germans began their counter-attacks the front British lines were practically surrounded, and several small parties of the 37th Brigade were cut off. One little post of the 6th Buffs was entirely isolated a thousand yards ahead of the British line, but held off the enemy all day, and 15 men, the survivors out of 40, made their way back in the evening, scrambling through {80} German trenches and shooting down all opposition. By that time the whole right of the Twelfth Division had been forced back to its original line, but the left still held firm in Scabbard Trench. The division had 2000 casualties in this day's fighting. The 169th Brigade had in the meanwhile maintained a difficult position with very great gallantry. This position had been always isolated upon the left, but it was covered upon the right by the successful advance of the Fourteenth Light Division to the south of the Cojeul River. About mid-day, however, a strong German advance forced the Fourteenth Division back to their original line, with the result that the right flank of the 169th Brigade became exposed. It was only when there seemed an imminent possibility of being cut off that this gallant brigade, which contained the 2nd London, Victorias, Westminsters, and London Rifle Brigade, was compelled to drop back to their original line. It was a barren and bloody day in this section of the line, save for the limited gain upon the south of the Scarpe. Two machine-guns and 100 prisoners were the meagre trophies of a long day's fighting. Yet in estimating results, one must never lose sight of that necessity for constant action which is the only method by which the side which has the stronger reserves can assert its eventual superiority in a war of attrition. To the north, the Fourth Division gained ground east of the Chemical Works and penetrated into Rœux, but were driven out once more, the 10th and 11th Brigades, especially the 1st Somersets and 2nd Seaforths, having very heavy losses. The Ninth Division got well forward upon their left, some of them over-shooting their objective--Uit Trench--and {81} being cut off. Very heavy counter-attacks in the afternoon broke upon this and upon the other sections of the Third Army. In the evening, both the Fourth and Ninth Divisions with gallant pertinacity tried to get forward again in the hope that their advanced posts might still be rescued, but they had no success. A hundred prisoners were taken, but at least as many were lost, including Highlanders, West Ridings, and Lancashire Fusiliers, victims of their own push and valour.
