Initially, this order was a semi-religious organization with its members taking vows of obedience, chastity, and poverty for the purpose of ministering to pilgrims traveling to the Holy Land. With more incidents of pilgrims being attacked, robbed, and enslaved by the Moslems, the Hospitallers quickly changed, out of necessity, to a great military organization.Proceeding to the stronghold of Rhodes, Geraise is eventually appointed commander of a war galley. The war galleys of the Knights of St. John patrolled the Mediterranean which was infested by Moorish corsair pirates.Join young Tresham in his many adventures on Rhodes with the Knights Hospitallers. Learn how this Order was the bulwark of Christendom against the invasion of the Turks. This much neglected area of history is brought to life by the masterful storytelling hand of G. A. Henty."
