It was returned to Christian and Templar control in the summer of 1240 in accordance with a truce between the Barons' Crusade and Emir Ismāʿīl of Damascus.

It stresses the cost of the re-building and upkeep, the strategic significance of the castle at the time of writing and the protection it provided to the Holy Places.
