The HQ’s party followed and in rear A & B Coys followed the same formation. After a halt for a meal the battalion reassembled for the final advance and on to the final objective which had not been and entirely made good. Its orders were to relieve the 43rd Infantry Brigade and if circumstances favourable to push on beyond the Feuchy line. At this time 2 cavalry brigades came up on the left and the final move was made in conjunction with the cavalry in a heavy snowstorm which blew into the face of the enemy and to a certain ? Screened our movements.
A considerable enemy artillery barrage and heavy machine gun fire from Wancourt and the ridge behind it caused some casualties. The cavalry advance was checked by wire in front of the objective. The 43rd infantry brigade withdrew as the battalion took over this position. The cavalry did the same after dark having suffered heavily and the situation remained stationary for the time. END
