The Franks have been forced to remain…
April 1250 CE
The Franks have been forced to remain in their camp for many weeks enduring an exhausting guerilla war, in which many crusaders have been captured and taken to Cairo.
Frankish supply ships from Damietta have been intercepted, and before long, the crusaders are suffering from famine and disease.
The Nile carries thousands of corpses away from al-Mansurah, and plague strikes the survivors.
King Louis IX proposes to the Egyptians the surrender of Damietta in exchange for Jerusalem and some towns on the Syrian coast.
The Egyptians, aware of the miserable situation of the crusaders, refuse the besieged king's offer.
The King has to issue orders for the agonizing retreat toward Damietta.
On April 5, covered by the darkness of night, the crusaders evacuate their camp and begin to flee northward towards Damietta.
Louis, stricken in turn, drags himself along in the rear guard of his disintegrating force, refusing the pleas of others to protect himself by moving out ahead.
In their panic and haste, the crusaders neglect to destroy a pontoon bridge they had set over the canal.
