Ashkelon in 1099 - The First Crusade
Soon after the Crusaders had taken Jerusalem, a great army of Moslems swept up from Egypt to encamp Ashkelon on the Palestinian coast west of the holy city. Despite being heavily outnumbered by the Christians, lead by Godfrey of Bouillon, Tancred of Taranto and Robert of Normandy, the Christians took the offensive and road out of Jerusalem towards the enemy.
At dawn the knights made a sudden charge into the center of the Moslems camp and took them completely by surprise. In the battle that followed, the entire Egyptian army was shattered with a few survivors taking refuge in the fortress of Ashkelon. When the garrison refused to surrender them, the victorious Crusaders returned to Jerusalem, satisfied they had eliminated any threat to their rule.
This battle ended the offensive phase of the first crusade, with five small Christian states being set up in Antioch, Edessa, Tripoli, Jerusalem and Galilee.
