The Fifth Crusade Departs for Egypt (1218)
On May 24, 1218, a fleet of Crusader ships left the port city of Acre bound for Egypt, marking the opening military move of the Fifth Crusade. Rather than attacking Jerusalem directly, European commanders pursued a new strategy: topple the powerful Ayyubid Sultanate by striking at its heart in Egypt. The campaign would ultimately target the strategic port city of Damietta, setting in motion nearly four years of warfare along the Nile.
A New Strategy for the Holy Land
By the early thirteenth century, European leaders had grown convinced that Jerusalem could not be held permanently unless the Ayyubid Sultanate, which controlled both Egypt and Syria, was decisively weakened. The Fourth Crusade had ended in disaster and controversy, sacking Constantinople instead of liberating the Holy Land, so Pope Innocent III and his successor Honorius III sought a more calculated approach for the Fifth Crusade. Rather than marching directly on Jerusalem, military planners, including the papal legate Pelagius of Albano and King Andrew II of Hungary, argued that seizing Egypt would cut off the sultanate's wealth and manpower, forcing the Ayyubids to trade Jerusalem for their economic lifeline. Egypt, ruled by Sultan al-Adil, brother of the famous Saladin, controlled vital Mediterranean trade routes and the fertile Nile Delta. Crusader leaders identified Damietta, a fortified port city near the Nile's mouth, as the ideal target: capturing it would open a path upriver toward Cairo itself. Preparations took years, drawing knights, foot soldiers, and clergy from Hungary, Austria, Germany, and the Low Countries. Acre, the last major Crusader stronghold in the Levant, served as the staging ground where forces gathered supplies, ships, and reinforcements throughout early 1218 before committing to the ambitious seaborne invasion.
Did You Know?
During the siege of Damietta, the friar Francis of Assisi traveled to the Crusader camp and personally crossed enemy lines to meet Sultan al-Kamil, hoping to convert him peacefully. The sultan reportedly received Francis with courtesy and sent him back unharmed, an encounter still remembered as a rare moment of mutual respect amid the Fifth Crusade's brutal warfare.
The Departure from Acre
On May 24, 1218, the assembled Crusader fleet finally set sail from Acre, carrying thousands of soldiers, along with horses, siege equipment, and provisions, across the eastern Mediterranean toward the Egyptian coast. The expedition included veteran commanders such as John of Brienne, the titular King of Jerusalem, and William I of Holland, who lent crucial leadership and naval resources. The choice of Damietta as the landing point reflected careful reconnaissance; the city's location near the Nile's Damietta branch made it both a gateway to Cairo and a formidable natural fortress, protected by marshland, a massive chain-link barrier across the river, and a heavily garrisoned tower guarding its harbor. Sailing conditions in late May typically favored the crossing, and within days the fleet reached the Egyptian shore, beginning what would become one of the longest and most grueling sieges of the Crusading era. The soldiers who disembarked faced not only Ayyubid defenders but also the punishing heat, disease, and flooding patterns of the Nile Delta. This departure represented the culmination of years of papal preaching, recruitment, and logistical planning, and it committed European forces to a campaign whose outcome would shape the balance of power in the eastern Mediterranean for years to come.
Legacy of the Egyptian Campaign
The Fifth Crusade's Egyptian strategy initially showed promise. Crusader forces captured the chain tower guarding Damietta's harbor in August 1218 and eventually took the city itself in November 1219 after a siege lasting roughly eighteen months. However, disagreements between Pelagius, who insisted on pressing toward Cairo, and John of Brienne, who favored negotiation, undermined the campaign's momentum. In 1221, overconfident Crusader leaders advanced up the Nile toward Cairo, only to be trapped by rising floodwaters deliberately released by the new sultan, al-Kamil. Surrounded and cut off from supplies, the Crusaders were forced to surrender Damietta in exchange for safe passage, ending the expedition in failure. Despite this outcome, the campaign demonstrated the strategic logic that would later influence the Seventh Crusade, led by Louis IX of France, who also targeted Egypt decades later. The Fifth Crusade also produced notable cultural encounters, including Francis of Assisi's peaceful meeting with al-Kamil during the siege, an episode still celebrated as an early example of interfaith dialogue. Ultimately, the departure from Acre on May 24, 1218, set in motion a costly and ambitious campaign that reshaped Crusading strategy, even as it failed to achieve its ultimate goal of reclaiming Jerusalem for Christendom.
