Ибн аль-Асир
Saladin's fierce determination to unite Egypt and Syria threatened the crusader states. Raymond mustered the troops of Jerusalem and Tripoli at Arqa in early 1175, but did not intervene in the conflict between Saladin and the Zengids. The defenders of the Homs citadel offered to set their Christian prisoners free if he provided military assistance for them; the prisoners included the hostages held as a guarantee for the arrears of Raymond's ransom. According to Ali ibn al-Athir, the Muslim burghers of Aleppo also urged Raymond to attack Saladin's troops. Raymond was willing to assist the defenders of Homs only if they immediately released their prisoners, but they refused his demand. William of Tyre later emphasized that the commanders of the crusader army doubted if the defenders of the Homs citadel actually wanted to release their prisoners.
