The wealth of material I have about my experiences during the war could fill an entire book. Five bulging diaries, augmented by hundreds of military-post letters to my parents, offer a daily record from September 1914 to November 1918, with the exception of 2 weeks at the height of a serious illness in August 1917. An extensive account would, however, be uninteresting since there is no lack of literature on the daily experience and suffering of soldiers in the First World War.
