The attack of the 9th had carried the Guards Division to its final objective, but the troops on the right had not been so successful, with the result that Seymour’s Brigade had taken over a salient more acute than a right angle, which made the general plan for a further attack rather awkward. On the evening of the 11th, Nos. 3 and 4 Companies moved up behind the King’s and No. 2 Companies with two platoons of the 2nd Battalion Scots Guards, which went to Egypt House. These two platoons had been specially detailed to get in touch with the 51st Brigade, which had met with so much opposition that it was unable to advance. During the night the enemy put down a heavy gas-shell barrage on the front line, and caused a large number of casualties. On the 12th a further attack was commenced, and the British barrage proved to be irregular and ragged, in marked contrast to the excellent barrages of July 31 and October 9. Under this barrage the 1st Battalion moved up to its objective, which it successfully captured. Lieutenant J. P. Bibby was killed as he advanced with No. 3 Company, and there were a good many casualties among other ranks. Unfortunately the Officer Commanding the two platoons of Scots Guards was killed, and Second Lieutenant L. G. Byng was sent to take his place.

Although the Battalions from the 51st Brigade reported themselves on their objectives, the contact patrols which were sent out failed to find any trace of them. It was afterwards found that this Brigade had reached its objective, passing over many Germans in doing so, and had swerved away too far to the right. Early in the morning the 1st Battalion reported a field-gun in action on the edge of the forest a few hundred yards in front of it. In response to an appeal for assistance, our artillery applied destructive fire to the spot indicated, and put down a box barrage to enable the patrols to go forward and destroy the gun, but owing to the hostile sniping this was impossible. On the night of the 12th the Battalion succeeded in clearing up the situation on the right, and getting in touch with the 51st Brigade. The following day it was relieved by De Crespigny’s Brigade, which now took over the line. During the relief Second Lieutenant R. Hall-Watt was killed, and Captain Rhodes was wounded, but remained at duty. The casualties among other ranks were 36 killed and 200 wounded or missing.
