Battle of Mansurah
Mansoura, EgyptThe ships of the Seventh Crusade, led by King Louis's brothers, Charles d'Anjou and Robert d'Artois, sailed from Aigues-Mortes and Marseille to Cyprus during the autumn of 1248, and then on to Egypt. The ships entered Egyptian waters and the troops of the Seventh Crusade disembarked at Damietta in June 1249.
Emir Fakhr ad-Din Yusuf, the commander of the Ayyubid garrison in Damietta, retreated to the camp of the Sultan in Ashmum-Tanah, causing a great panic among the inhabitants of Damietta, who fled the town, leaving the bridge that connected the west bank of the Nile with Damietta intact. The Crusaders crossed over the bridge and occupied Damietta, which was deserted. The Crusaders were encouraged by the news of the death of the Ayyubid Sultan, as-Salih Ayyub. The Crusaders began their march towards Cairo.
Early on the morning of February 11, the Muslim forces launched an offensive against the Frankish army, with Greek Fire, but were repulsed with heavy losses, ending in a Frankish victory.
