The Battle of Ascalon took place on 12 August 1099 shortly after the capture of Jerusalem. Often considered the last action of the First Crusade, the Crusader army led by Godfrey of Bouillon defeated and drove off a Fatimid army of Egypt. The Crusaders completed their primary objective of capturing Jerusalem on 15 July 1099. In early August, they learned of the approach of a 20,000-strong Fatimid army under vizier al-Afdal Shahanshah. Under Godfrey's command the 10,200-strong Crusader army took the offensive, leaving Jerusalem on 10 August to protect the newly established Kingdom of Jerusalem. The Crusaders marched barefoot, carrying the relic of the True Cross with them, accompanied by patriarch Arnulf of Chocques. The army marched south from Jerusalem, approaching the vicinity of Ascalon on 11 August and capturing Egyptian spies who revealed al-Afdal's dispositions and strength. (The distance from Jerusalem to Ascalon is about 77 km (48 mi)). At dawn on 12 August, the Crusader army launched a surprise attack on the Fatimid army still sleeping in its camp outside the defensive walls of Ascalon.
