Events By place Fifth Crusade February – Pelagius orders the Crusader army to prepare an attack against the Egyptians but is unsuccessful because of the weather and strength of the defenders. Sultan Al-Kamil, in command of the Egyptian forces, is almost overthrown by a conspiracy in his entourage. He considers fleeing to the Ayyubid Emirate of Yemen, ruled by his son Al-Mas'ud Yusuf, but the arrival of his brother Al-Mu'azzam, with reinforcements from Syria, ends the conspiracy. On hearing the news that Al-Kamil and his army is retreating to Cairo, the Crusaders march to Al-Adiliya. After driving back an assault from the garrison of Damietta they occupy the town on February 5. April – The Crusaders surround Damietta, with the Italian forces to the north, Knights Templar and Knights Hospitaller to the east – and King John I of Jerusalem with his French and Pisan troops to the south. The Frisians and German troops occupy the old camp across the Nile. A new wave of Crusader reinforcements from Cyprus arrive led by Walter III of Caesarea. Meanwhile, Al-Mu'azzam decides to dismantle the fortifications at Mount Tabor and other defensive positions, as well as Jerusalem itself, in order to deny their protection should the Crusaders prevail there. Some fanatics wish to destroy the Holy Sepulchre, but this is refused by Al-Mu'azzam. April 7 – Al-Muzaffar II, Ayyubid ruler of Hama, arrives in Egypt with Syrian reinforcements, leading multiple attacks on the Crusader camp at Al-Adiliya, with little impact. In the meantime, new Crusader forces, bring badly-needed supplies. Egyptian attacks continue through May, with Crusader counter-attacks utilizing a Lombard device known as a carroccio, confounding the defenders. July 8 – Pelagius begins multiple attacks at Damietta, using Pisan and Venetian troops. Each time they are repelled by the defenders, using Greek fire. A counter-offensive led by Al-Kamil on the Templar camp is repulsed on July 31 by their new Grand Master Peire de Montagut, supported by the Teutonic Knights – where the Crusaders reform and pursue the enemy outside the gates. August 29 – The Crusaders attack the Egyptian camp in the Battle of Faraskur and the Muslims pretend a feigned retreat to Mansoura. John I advises to camp overnight, because there is no fresh water in the region between the Nile
