At 10 A.M. troops of the 2nd Division could be observed away to our right, with bodies of the enemy penetrating between them and the 154th Brigade near the Butte de Warlencourt. At 10 A.M. the 19th Division was seen withdrawing on our left. At 11 A.M. the enemy was in Le Barque, and were advancing along our front with light field-guns closely supporting the infantry. He was held in front without difficulty, and sustained considerable casualties, machine-guns under Lieutenants Strapp and Broadbent having been repeatedly in action during the day. The right flank was, however, in constant danger of being turned, as the enemy first entered Le Sars and then directed his advance on Pys, so that the 152nd Brigade had to dispose troops facing south and west. Here hand-to-hand fighting occurred, on one occasion the enemy’s line being driven back and a prisoner secured in a charge.
However, at 2.15 P.M. the whole line had to fall back to prevent being surrounded, the adjutant and two other officers of the 6th Seaforth Highlanders fighting with a party of men to the end, all being either killed or captured. Lieut.-Colonel Gemmell, commanding the 8th Royal Scots, was also killed, and Colonel Long, commanding the 5th Gordon Highlanders, wounded.
The 154th Brigade therefore took up a position on the high ground east of Pys, and the 152nd and 153rd Brigades east of Irles, and the 8th Royal Scots south of Achiet-le-Petit. Here again the 154th Brigade were in danger of being completely surrounded, and had to fall back to the south of Irles.
In this position the troops engaged parties of the enemy massing for attack successfully; but the exhaustion of the men had become such that they could no longer offer a protracted resistance. They had been in action continuously since the morning of 21st March; and at the end of five days, in which the fighting during the day and the intense cold of the nights had denied to them any real rest, their vitality was at its lowest ebb.
The remnant of the Division was thus left still facing the enemy, its three brigade headquarters just in rear of the fighting line still in the same order of battle in which they had begun the engagement, but their fighting efficiency was gone. With no British troops on their right nearer than Albert, there was no other alternative left but to break off the engagement and withdraw. Accordingly orders were issued for the Division to concentrate at Colincamps, where Divisional headquarters had opened at 4.35 P.M.
The withdrawal of all that was left of the Highland Division along the road from Puisieux to Colincamps was a melancholy spectacle: a long line of men and horses, tired and exhausted almost beyond the limits of human endurance, dragging themselves along, many with undressed wounds. The men fell back in groups, not as formed bodies, but not as in a disorderly rout. Every man retained his arms and equipment, and in spirit would have taken up any line ordered and continued the struggle; but in their acute stage of exhaustion further effective resistance was out of the question, and so was not asked of them.
The total casualties sustained by the Division in this action were 219 officers and 4696 other ranks. Of these, the infantry losses amounted to 157 officers and 3744 men. Assuming that the nine battalions of infantry each went into action 600 strong, excluding transport drivers, &c., it will be seen that out of a total of 5400 officers and men only 1500 survived. These figures in themselves show the nature of the fighting. The casualties in officers were also, as is always the case, heavy. Of the 10 commanding officers of the infantry and pioneer battalions, 3 were killed and 3 wounded.

Not only had the men offered a magnificent resistance, but their commanders had handled them admirably. In spite of the fact that after the first few hours of the engagement one or more flanks had at all times to be defended as well as the front, the enemy succeeded in cutting off no considerable body of troops; and yet no withdraw a took place until the close of the action, except in close contact with the enemy.
