The Siege of Jerusalem took place from June 7 to July 15, 1099 during the First Crusade. The Crusaders stormed and captured the city from Fatimid Egypt. Throughout the siege, attacks were made on the walls, but each one was repulsed. The Genoese troops, led by commander Guglielmo Embriaco, had previously dismantled the ships in which the Genoeses came to the Holy Land; Embriaco, using the ship's wood, made some siege towers. These were rolled up to the walls on the night of July 14 much to the surprise and concern of the garrison. On the morning of July 15, Godfrey's tower reached his section of the walls near the northeast corner gate, and according to the Gesta two Flemish knights from Tournai named Lethalde and Engelbert were the first to cross into the city, followed by Godfrey, his brother Eustace, Tancred, and their men. Raymond's tower was at first stopped by a ditch, but as the other crusaders had already entered, the Muslim guarding the gate surrendered to Raymond of Toulouse.
