'Anyone picking up this book might be forgiven for asking whether we really need another study of the British army during the First World War, and, if we do, whether a biography of a general known to very few besides specialist military historians is the right way to approach the subject. The answer to both questions is an emphatic yes... [Robbins] has now written a study of Sir Henry Horne that not only helps to rescue his career for posterity but also sheds a good deal of light on how the army went about its business between 1914 and 1918.'
