The expedition, though led by Shirkuh, had professedly been to restore Shawar to the wazirate, and now established in office Shawar only desired to get rid of the Turks. He kept Shirkuh out of the royal city, entirely refused to allow him any share in the results of the conquest, and declined to pay the expected indemnity. He felt, no doubt, that the decisive factor had been the revolt against Dirgham rather than the help of the Turks. But Shirkuh was not a likely person to suffer this conduct with impunity, and sent his nephew Saladin to occupy Bilbays and thus hold the Sharqiya or eastern province, one of the four great divisions of Egypt, the other three being Gharbiya or the western province, Qus or Upper Egypt, and Alexandria or Lower Egypt. This move on the part of Shirkuh moved Shawar to appeal to Amalric, and an army of Franks marched down to besiege Bilbays. The siege lasted three months and then Amalric was obliged to retire and call an armistice as the Turkish hosts of Nur ad-Din were proceeding south to the relief of Saladin. It was agreed that the body of Syrians occupying Bilbays should be allowed to evacuate without interference, and they marched out between the armies of the Egyptians and the Franks. For the moment matters had produced a stale-mate, but Shirkuh was fully convinced that Egypt could be conquered without much difficulty, and that this would be the right way to check the Franks effectually. Nur ad-Din, with characteristic caution, hesitated over so great an undertaking which would necessitate the employment of his forces in the far south and leave the Frankish kingdom of Jerusalem between his capital and the bulk of his army, but the project was warmly espoused by the Khalif of Baghdad, and at length Nur ad-Din acquiesced and a new expedition started from Damascus in the early part of 562.
