CHAPTER XIII CHRISTENDOM AND ISLAM ISLAM had taken nearly two hundred years to expel the Franks from Palestine. It is astonishing that the Latins ever won a kingdom in the East, more astonishing still that they were able to retain their footing for so long a period. The almost constant quarrels among the Moslem princes saved the Westerners from extinction on numerous occasions but, even when Islam was united, the Franks succeeded in holding territory in the midst of their enemy for many years. Some- times a Crusade from the West had protected the Christians in a crisis j sometimes natural forces, such as earthquakes, had been their saviour; sometimes the Moslem princes had been betrayed by their followers. Most of the credit, however, belongs to the military Orders. They had no equal in the East for discipline, skill and courage. The Moslem victories were, with a few exceptions, won by sheer force of numbers. The armies of Islam and Christen- dom in the Holy Land were always vastly disproportionate, and there is hardly a single great battle in which the Franks were not outnumbered by at least three to one. Such a disparity was bound to tell in the end, and, had it not been for the fortresses erected by the Christians, would have told much sooner. The castles built by the military Orders and the Christian nobles were almost impregnable. A few hundred defenders behind the walls of a fortress such as Safed could resist an army, and famine was no menace in . castles which were often provisioned to withstand a siege of as long as three years.
