An officer's diary-style regimental history traces a Territorial battalion from mobilization and home defence duties through training, embarkation and sustained service on the Western Front. Presented chapter by chapter, it details marches, billets, trench life and actions at Festubert, Picardy, Arras, the Somme, Ypres and the Third Battle of Ypres, combining operational descriptions with everyday logistics, casualties and personal anecdotes. The account concludes with reflections and supporting appendices that compile rolls, orders and administrative records to document the unit's wartime experience.
