Al-Ma'mum, the new Vizier of Egypt, organizes a major invasion of Crusader land in 1123.

The Fatimids plan to capture the coastal city of Jaffa.

In this era, the Egyptian armies usually deploy with Sudanese archers on foot, supported by dense formations of Arab and Berber light cavalry.

Unfortunately for the Fatimids, this relatively immobile array provides the Frankish heavy cavalry with an ideal target, resulting in a massacre of the foot-soldiers.

The defeat is decisive.

Except for continued raids from Ascalon until the Siege of Ascalon in 1153, Egypt will cease to be a threat to the Crusader states until the rise of Saladin in 1169.
