What happened
Rather than attack the Levant directly, the Fifth Crusade targeted Egypt first, reasoning that Jerusalem would fall on its own if cut off from Egyptian support. The crusader army, led in the field by John of Brienne, king of Jerusalem, captured the fortress city of Damietta in November 1219 after a grueling siege. The Egyptian sultan al-Kamil then offered to trade Jerusalem itself for a crusader withdrawal from Egypt, an offer John of Brienne and the Teutonic Knights wanted to accept but which the Templars, Hospitallers, and the campaign's senior cleric, Cardinal Pelagius, rejected as unsustainable without key fortresses al-Kamil intended to keep. The crusaders pressed on toward Cairo instead. Al-Kamil sank ships behind the advancing army to block retreat, positioned troops to cut off any escape by land, and then opened the Nile's sluice gates, flooding the surrounding fields waist-deep. Trapped and waterlogged, the crusader army surrendered on 28 August 1221, forfeiting Damietta and all its gains.
Why it matters
The rejection of al-Kamil's offer to trade Jerusalem for Egypt is one of the great missed opportunities of the entire crusading era, and the campaign's collapse in the Nile floodwaters became a byword for crusading overreach and poor logistics.
How we know
The campaign's leadership disputes and its final collapse are described in detail in the World History Encyclopedia's narrative, which draws on chronicle accounts of the negotiations between Cardinal Pelagius and al-Kamil.
