The monks of war:

The Templars, the Hospitallers (later Knights of Malta), the Teutonic Knights, and the Knights of the Spanish and Portuguese orders were 'noblemen vowed to poverty, chastity and obedience, living a monastic life in convents which were at the same time barracks, waging war on the enemies of the Cross'. The first properly disciplined Western troops since Roman times, they played a major role in defending the crusader kingdom of Jerusalem, in the 'Baltic Crusades' which created Prussia, in the long reconquest of Spain from the Moors, and in fighting the 'Infidel' right up to Napoleonic times. This celebrated book tells the whole enthralling story, recreating such epics as the sieges of Rhodes and Malta and the destruction of the Templars by the Inquisition. Acclaimed on publication, it has now been revised and updated, with a concluding chapter to take events into the 1990s.
