A detailed regimental history of the Grenadier Guards' wartime service, recounting company- and battalion-level movements, engagements, and routines across campaigns from early 1916 through early 1918. The narrative combines chronological chapters on major actions — including the Somme, Boesinghe, Broembeek, and Cambrai — with accounts of daily trench life, command changes, casualties, training accidents, maps, and portraits. It outlines tactical dispositions, defensive works, bombing and gas precautions, and the experiences of officers and men while documenting organization, operations, and logistical details for the regiment's battalions.
