During the night 16/17th October the enemy poured gas shells into Vaux Andigny, causing considerable casualties both to the troops forming up just outside and to those who had to pass through a little later. Zero was at 5.20 a.m., and the attack commenced in a dense fog, which in the fan-shaped advance caused a good deal of loss of direction, although the 18th Infantry Brigade on the left had laid out long direction tapes to give the troops the initial direction. The latter brigade was held up at the start by uncut wire, which caused it to lose its barrage. It also encountered a good deal of opposition on Bellevue Ridge. It was, however, carried forward by the oncoming waves of the 1st Division, which were to pass through to a further objective, and together the troops of the two divisions made good the objective of the 18th Infantry Brigade. The fog was so dense that all direction was lost, although the 11th Essex Regiment took the unusual precaution of sending its men forward arm-in-arm. Notwithstanding every precaution troops of the 11th Essex eventually fetched up at Regnicourt, which was on the right of the objective allotted to the 46th Division, who attacked on our right. Troops of all three divisions also reached Andigny les Fermes, which was in the objective of the 46th Division. The 16th Infantry Brigade was more fortunate, and was assisted in maintaining its direction by the railway, with the result that it gained its whole objective in good time and with very little trouble. The day's captures were 26 officers, 599 other ranks, 5 trench-mortars, and 82 machine-guns. The 1st Division having passed through, the 6th Division was now withdrawn from the line to the neighbourhood of Bohain for a day or two.
