 The defenders had sought help from Saif ad-Din Ghazi I of Mosul and Nur ad-Din of Aleppo, who personally led an attack on the crusader camp.The crusaders were pushed back from the walls into the orchards, leaving them exposed to ambushes and guerrilla attacks.According to William of Tyre, on 27 July the crusaders decided to move to the plain on the eastern side of the city, which was less heavily fortified but had much less food and water.
