سلطان مصر
In September 1239, Armand arrived at Acre. He made a treaty with Sultan of Damascus, in parallel with the Hospitaller treaty with the Sultan of Egypt. In 1244 the Sultan of Damascus demanded that the Templars help repel the Seljuks from Asia Minor. In October 1244, the Templars, Hospitallers and Teutonic Knights, together with the Sultan of Damascus, confronted the Sultan of Egypt and his Khwarezmian allies at the Battle of La Forbie. The Christian-Muslim coalition was defeated, with more than 30,000 deaths. Some Templars and Hospitallers reached Ascalon, still in Christian hands. Armand may have been killed during the battle, or may have been captured and died soon after.
