'Wars have often determined the character of society. Society in exchange has determined the character of wars. This is the theme of Michael Howard's stimulating book. It is written with all his usual skill and in its small compass is perhaps the most original book he has written. Though he surveys a thousand years of history, he does so without sinking in a slough of facts and draws a broad outline of developments which will delight the general reader.' - A. J. P. Taylor, Observer.
