When one remembers the amount of shells which had been deluged on the Germans in the Pheasant Trench position, one cannot but admire the resolute manner in which they resisted our attack. It was indeed the strength of their resistance which made the capture of this line by the 4th Seaforths and 9th Royal Scots such a magnificent performance. One can gauge the severity of the fighting by the fact that so much rifle ammunition had been used by the infantry in this attack that 12,000 rounds had to be sent up to the parties consolidating the Blue line.

The enemy's barrage did not open until five minutes after the attack was launched, and was then particularly heavy on the area between our original front line and the Langemarck road.

Both the battalions detailed for the capture of the Blue line, the 4th Gordon Highlanders and the 7th Argyll and Sutherland Highlanders, had suffered serious casualties from having become involved in the fighting for Pheasant Trench before they formed up under the barrage. "D" Company of the 7th Argyll and Sutherland Highlanders had also suffered heavily from shell-fire when advancing from the old British front line.

The 7th Argyll and Sutherland Highlanders reached the Blue line after having overcome, chiefly by means of rifle grenades, Flora Cot, Quebec Farm, and Bavaroise House, capturing four machine-guns, of which one was turned on the enemy with good results, and about thirty prisoners.

The 4th Gordon Highlanders, who had already lost five officers before forming up under the barrage, had their first fight after the barrage moved forward at Pheasant Farm Cemetery. Here a lance-corporal was responsible for capturing two machine-guns and twenty-eight prisoners. Malta House, Bose House, and Delta House were all captured after stiff fighting, several machine-guns being destroyed.

By the time the 4th Gordon Highlanders had reached the Blue line, they had only three officers and six platoons of about ten men each in the front line; the remainder of the reserve company with two officers was therefore sent up as a reinforcement.

The situation on the left was a delicate one, as the neighbouring Division attacking on that flank had been unable to make progress, so that the two battalions on the left had between them to form a defensive flank some 1000 yards in depth. The Blue line was thus consolidated, as had been intended, as far as Rose House, and the line then bent round towards White House.
