This is a revised edition of R. C. Smail's classic account of the military achievements of the Crusaders in the context of a 'feudal society organized for war'. A new bibliographical introduction and an updated bibliography have been provided by Christopher Marshall, while the original plates section has been replaced by a series of new subjects. In covering the period 1097-1193, this edition also complements Dr Marshall's own Warfare in the Latin East, 1192 1291, also available in a paperback edition."
