The Mongol commander at Shiraz and Uns Kahtun’s chief minister took proper measures and marched against this descendant of Mohammed. They met near Guvar. Many thought that the “Madhi” was assisted by spirits, and that whoso attacked him would be paralyzed. For some time no man in the army of Shiraz would raise a hand against Sherif. At last two warriors ventured to discharge arrows at him, others followed this example. The Mongols then charged the insurgents, who fled; Sherif was killed in the mêlée with most of his followers. At the first news of this uprising Hulagu commanded to bastinado Altadju for sparing the people of Shiraz, and he ordered a tuman of warriors to punish them. When he learned, however, that Sherif ud din had been slain, and that the people of Shiraz were innocent, for the greater part, he recalled his first order. When Uns Khatun had ruled for one year she was sent to the Ordu to marry Mangu Timur, son of Hulagu, to whom she brought a rich dowry. Fars was managed thenceforth by the Divan, though in the name of Uns, who died during 1287 in Tebriz. With her died the Salgarid dynasty. At the end of 1264 the Mongols laid siege to El Biret. This place was considered the master stronghold of Syria. Akkush commanded for the Sultan of Egypt. The Mongols filled up the fosse of the fortress with wood. The besieged made a tunnel to that fosse and burned all the wood which then filled it. The Mongols worked with seventeen catapults, but they met firm and active resistance, women showing more courage than men in that struggle. News had reached Beibars earlier that Franks were advising the Mongols, by letter, to march into Syria during spring when the troops were at home, and their horses were out grazing. As soon as he heard that the Mongols were attacking El Biret, the Sultan sent a corps of four thousand to oppose them. He sent four days later another four thousand, who were to reach El Biret by forced marches. The Sultan himself set out January 27, 1265, and by February 3 was at Gaza, where he learned that the enemy had raised the siege and retreated. The Mongols at approach of their opponents had removed all their catapults, sunk their boats, and fled quickly. Beibars gave command to bring in arms and supplies for a siege that might last a whole decade. Three hundred robes of honor and a hundred thousand drachmas in money were sent out by him to reward those who had fought in El Biret.
