Sir Alan Patrick Herbert CH (usually writing as A. P. Herbert or A. P. H., 24 September 1890 - 11 November 1971) was an eng humorist, novelist, playwright and law reform activist. He was an independent Member of Parliament (MP) for Oxford University for 15 years, five of which he combined with service in the Royal Navy. "The Secret Battle" is a novel by A. P. Herbert, first published in 1919. The book draws upon Herbert's experiences as a junior infantry officer in the First World War, and has been praised for its accurate and truthful portrayal of the mental effects of the war on the participants. It was one of the earliest novels to contain a detailed description of Gallipoli, or to challenge the Army's executions of soldiers for desertion. It is noticeable as being sharply different from Herbert's later work-there is no note of humour or lightness in the novel, simply a stark and simple narrative. (Excerpt from Wikipedia)
