being killed or captured—Saif al-Din narrowly escaped. The Zengid army's camp, horses, baggage, tents, and stores were seized by the Ayyubids. The Zengid prisoners of war, however, were given gifts and freed. All of the booty from the Ayyubid victory was accorded to the army, Saladin not keeping anything himself. He continued towards Aleppo, which still closed its gates to him, halting before the city. On the way, his army took Buza'a and then captured Manbij. From there, they headed west to besiege the fortress of A'zaz on 15 May. Several days later, while Saladin was resting in one of his captain's tents, an Assassin rushed forward at him and struck at his head with a knife. The cap of his head armour was not penetrated and he managed to grip the Assassin's hand—the dagger only slashing his gambeson—and the assailant was soon killed. Saladin was unnerved at the attempt on his life, which he accused Gumushtugin and the Assassins of plotting, and so increased his efforts in the siege. A'zaz capitulated on 21 June, and Saladin then hurried his forces to Aleppo to punish Gumushtigin. His assaults were again resisted, but he managed to secure not only a truce, but a mutual alliance with Aleppo, in which Gumushtigin and as-Salih were allowed to continue their hold on the city, and in return, they recognized Saladin as the sovereign over all of the dominions he conquered. The emirs of Mardin and Keyfa, the Muslim allies of Aleppo, also recognised Saladin as the King of Syria. When the treaty was concluded, the younger sister of as-Salih came to Saladin and requested the return of the Fortress of A'zaz; he complied and escorted her back to the gates of Aleppo with numerous presents. Campaign against the Assassins Saladin had by now agreed to truces with his Zengid rivals and the Kingdom of Jerusalem (the latter occurred in the summer of 1175), but faced a threat from the Isma'ili sect known as the Assassins, led by Rashid ad-Din Sinan. Based in the an-Nusayriyah Mountains, they commanded nine fortresses, all built on high elevations. As soon as he dispatched the bulk of his troops to Egypt, Saladin led his army into the an-Nusayriyah range in August 1176. He retreated the same month, after laying waste to the countryside, but failing to conquer any of the forts. Most Muslim historians claim that Saladin's uncle, the
