Following the conquest of Crete, Nikephoros returned to the east and marched a large and well-equipped army into Cilicia. In February 962 he captured Anazarbos, while the major city of Tarsus ceased to recognize the Hamdanid Emir of Aleppo, Sayf al-Dawla. Nikephoros continued to ravage the Cilician countryside, defeating the governor of Tarsus, ibn al-Zayyat, in open battle; al-Zayyat later committed suicide on account of the loss. Thereafter, Nikephoros returned to the regional capital of Caesarea. Upon the beginning of the new campaigning season al-Dawla entered the Byzantine Empire to conduct raids, a strategy which left Aleppo dangerously undefended. Nikephoros soon took the city of Manbij. In December, an army split between Nikephoros and John I Tzimiskes marched towards Aleppo, quickly routing an opposing force led by Naja al-Kasaki. Al-Dawla's force caught up with the Byzantines, but he too was routed, and Nikephoros and Tzimiskes entered Aleppo on 24 or 23 December. The loss of the city would prove to be both a strategic and moral disaster for the Hamdanids. It was probably on these campaigns that Nikephoros earned the sobriquet, "The Pale Death of the Saracens". During the capture of Aleppo, the Byzantine army took possession of 390,000 silver dinars, 2,000 camels, and 1,400 mules.
