The crusaders decided to attack Damascus from the west, where orchards of Ghouta would provide them with a constant food supply. Having arrived outside the walls of the city, they immediately put it to siege, using wood from the orchards. 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. Afterwards, the local crusader lords refused to carry on with the siege, and the three kings had no choice but to abandon the city. The entire crusader army retreated back to Jerusalem by 28 July.
