The Battle of Damietta took place in 1219 during the Fifth Crusade, where Crusader forces aimed to capture the Egyptian city of Damietta. The battle was part of a larger campaign to gain control over Egypt, which was seen as a strategic point for further Crusader advances in the Holy Land. The Crusaders, led by figures such as John of Brienne and Pelagius of Albano, initially succeeded in capturing Damietta. However, their victory was short-lived, as they faced challenges from the Ayyubid forces, leading to a protracted conflict that ultimately ended in a stalemate and the eventual withdrawal of Crusader troops.
