arrived in Damascus amid general acclamation and rested at his father's old home there, until the gates of the Citadel of Damascus, whose commander Raihan initially refused to surrender, were opened to Saladin four days later, after a brief siege by his brother Tughtakin ibn Ayyub. He installed himself in the castle and received the homage and salutations of the inhabitants. Further conquests in Syria Leaving his brother Tughtakin ibn Ayyub as Governor of Damascus, Saladin proceeded to reduce other cities that had belonged to Nur al-Din, but were now practically independent. His army conquered Hama with relative ease, but avoided attacking Homs because of the strength of its citadel. Saladin moved north towards Aleppo, besieging it on 30 December after Gumushtigin refused to abdicate his throne. As-Salih, fearing capture by Saladin, came out of his palace and appealed to the inhabitants not to surrender him and the city to the invading force. One of Saladin's chroniclers claimed "the people came under his spell". Gumushtigin requested Rashid ad-Din Sinan, chief da'i of the Assassins of Syria, who were already at odds with Saladin since he replaced the Fatimids of Egypt, to assassinate Saladin in his camp. On 11 May 1175, a group of thirteen Assassins easily gained admission into Saladin's camp, but were detected immediately before they carried out their attack by Nasih al-Din Khumartekin of Abu Qubays. One was killed by one of Saladin's generals and the others were slain while trying to escape. To deter Saladin's progress, Raymond of Tripoli gathered his forces by Nahr al-Kabir, where they were well placed for an attack on Muslim territory. Saladin later moved toward Homs instead, but retreated after being told a relief force was being sent to the city by Saif al-Din. Meanwhile, Saladin's rivals in Syria and Jazira waged a propaganda war against him, claiming he had "forgotten his own condition [servant of Nur ad-Din]" and showed no gratitude for his old master by besieging his son, rising "in rebellion against his Lord". Saladin aimed to counter this propaganda by ending the siege, claiming that he was defending Islam from the Crusaders; his army returned to Hama to engage a Crusader force there. The Crusaders withdrew beforehand and Saladin proclaimed it "a victory opening the gates of men's hearts". Soon after, Saladin entered Homs and captured its citadel in March 1175, after stubborn resistance from its defenders. Saladin's successes
