In August, having gained the initiative, the Allies launched their own offensive commencing at Amiens on 8 August 1918, where the battalions of the 1st Brigade were attached temporarily to the 4th Division, to act as its reserve, guarding the river crossing at Cerisy. Following this they were involved in the advance through Chipilly and Lihons, remaining in reserve until 11 August. Throughout the period of the first week of the offensive, the battalion suffered three officers and 45 other ranks killed or wounded.
