body. Al-Maqrizi added to the rumor by claiming Muhammad's tomb was going to be relocated to Crusader territory so Muslims would make pilgrimages there. Al-Adil had his warships moved from Fustat and Alexandria to the Red Sea under the command of an Armenian mercenary Lu'lu. They broke the Crusader blockade, destroyed most of their ships, and pursued and captured those who anchored and fled into the desert. The surviving Crusaders, numbered at 170, were ordered to be killed by Saladin in various Muslim cities. From the point of view of Saladin, in terms of territory, the war against Mosul was going well, but he still failed to achieve his objectives and his army was shrinking; Taqi al-Din took his men back to Hama, while Nasir al-Din Muhammad and his forces had left. This encouraged Izz al-Din and his allies to take the offensive. The previous coalition regrouped at Harzam some 140 km from Harran.

Saladin aimed to persuade the caliph claiming that while he conquered Egypt and Yemen under the flag of the Abbasids, the Zengids of Mosul openly supported the Seljuks (rivals of the caliphate) and only came to the caliph when in need. He also accused Izz al-Din's forces of disrupting the Muslim "Holy War" against the Crusaders, stating "they are not content not to fight, but they prevent those who can". Saladin defended his own conduct claiming that he had come to Syria to fight the Crusaders, end the heresy of the
