A wartime diary of dated first-person entries alternates between training and life behind the lines, moments of ordinary leisure, and stark reports from the frontline, recording mud, filth, fatigue, casualty care, small comforts, and acts of devotion. The tone shifts between wry observation and blunt detail as it describes military operations, raids, and the daily routine of trench warfare, while reflecting on the moral and social costs of modern conflict and arguing that unvarnished accounts of suffering are necessary to help prevent future wars.
