The Secret Battle is a novel about a soldier executed for cowardice. The novel follows the career of a young officer, Harry Penrose. A sensitive, educated young man, Penrose had enlisted in the ranks in 1914, immediately after completing his second year at Oxford. After six months in training he had been prevailed upon by his relatives – like most educated volunteers – to take a commission as an officer. Penrose slowly asserts himself; the war takes a toll on his personality, but he begins to live up to his early dreams of heroism. However, his creeping self-doubt grows by degrees; he is reassigned from his post as scouting officer once on the Somme, knowing he cannot face another night patrol, and earns the wrath of his commanding officer – an irascible Regular colonel – over a trivial incident. The book draws upon author'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.
