On January 1 the 4th Battalion went by train to Athies, and moved into the support line with three Companies near Northumberland Lane, and one Company attached to the 1st Battalion Grenadier Guards. Lieut.-Colonel Pilcher was at the time on leave, and the Battalion was commanded by Major Walker. On the 5th three Companies were moved up into the front trenches with one Company in reserve. On the following day Company Sergeant-Major W. Stretton, Lance-Sergeant C. Hatton, and Lance-Corporal W. Long, all non-commissioned officers of great gallantry and experience, were killed by a Grenatenwerfer, while Captain Layton of the same Company was wounded.
