were prepared to let the crusaders keep Syria if they agreed not to attack Fatimid Palestine, a state of affairs perfectly acceptable between Egypt and Byzantium before the Turkish invasions. But the crusaders could not accept any settlement that did not give them Jerusalem. Nevertheless, the Fatimids were treated hospitably and were given many gifts, plundered from the Seljuks who had been defeated in March, and no definitive agreement was reached. Nevertheless, it taught the crusaders the value of diplomacy and they decided to send an embassy to Duqaq of Damscus asking for his neutrality, stating they had no ambitions on his territory. They were, however, rejected by Duqaq. Capture of Antioch The siege continued, and at the end of May 1098 a Turkish army from Mosul under the command of Kerbogha approached Antioch. This army was much larger than the previous attempts to relieve the siege. Kerbogha had joined with Ridwan and Duqaq and his army also included troops from Persia and from the Ortuqids of Mesopotamia. The crusaders were luckily granted time to prepare for their arrival, as Kerbogha had first made a three-week-long excursion to Edessa, which he was unable to recapture from Baldwin of Boulogne, who had becomes its ruler earlier in March 1098.

Firouz's motivation was unclear even to Bohemond, perhaps avarice or revenge, but he offered to let Bohemond into the city in exchange for money and a title. Bohemond then approached the other crusaders and offered access to the city, through Firouz, if they would agree to make Bohemond the Prince of Antioch. Raymond was furious and argued that the city should be handed over to Alexios, as they had agreed when they left Constantinople in 1097, but Godfrey, Tancred, Robert, and the other leaders, faced with a desperate situation, gave in to Bohemond's demand. Despite this, on 2 June, Stephen of Blois and some of the other crusaders deserted the army. Later on the same day, Firouz instructed Bohemond to feign a march south over the mountains to ostensibly confront Kerbogha, but then to double-back at night and scale the walls at the Tower of the
