In 1097 the Crusaders divided their forces at Heraclea Cybistra and Tancred entered the Levant by passing south through the Cilician Gates. He displayed the skills of a brilliant tactician by seizing five of the most important sites in Cilicia Pedias, which included the ancient cities of Tarsus and Adana, the great emporium at Mopsuestia, and the strategic castles at Sarvandikar and Anazarbus. The last three settlements were annexed to the Principality of Antioch. During their fourteen-year occupation of Anazarbus the Crusaders built the magnificent donjon atop the center of the fortified outcrop. At Sarvandikar, which controlled the strategic Amanus Pass, Tancred imprisoned Raymond of Saint-Gilles in 1101/02.
