The wedding took place in Kerak Castle. Saladin, the Ayyubid sultan of Egypt and Syria laid siege to the fortress. According to Ernoul's chronicle, Stephanie of Milly sent meals to the besiegers from the feast and Saladin forbade his engineers to destroy the tower of the fortress in which Humphrey and Isabella spent the wedding night. Baldwin IV assembled a relief army and departed from Jerusalem to Kerak, although he was unable to ride a horse. Saladin lifted the siege and retreated without fight on 3 or 4 December.
