The three sons of Bedr ud din Lulu, then princes of Mosul, Jeziret and Sindjar, set out with the Kalif, but halted at Rahbah despite his entreaties, leaving with him, however, sixty Mameluks. Mostansir was joined at that place by Yezid, an emir who was chief of the Al Fazl, and had with him four hundred Beduins, and by Eidikin, an emir who brought with him thirty horsemen from Hamath. Advancing by the western bank of the Euphrates they met at Ana the Abbasid Iman, Al Hakim, attended by seven hundred Turkmen; Al Burunli, the Mameluk chief who had seized command of Aleppo in spite of the Sultan, had made Al Hakim set out with these horsemen. The Kalif overtook Hakim and his party at the river where the seven hundred Turkmen deserted. Thereupon Hakim adhered to Mostansir, and was ready to assist in installing him at Bagdad. The people of Ana had refused to receive Hakim. The Sultan of Egypt, they said, had recognized a Kalif who was coming; to him alone would they open the gates of their city. When Mostansir appeared he was met with due homage. Haditse acted like Ana, but Hitt refused sternly to open its gates and was taken by violence. The Kalif entered the city November 24 with his warriors, who plundered both Christians and Jews without mercy. Kara Buga, the commander of those Mongols who guarded Arabian Irak, hearing of Mostansir’s approach marched against Anbar with five thousand cavalry. Anbar was friendly to the Kalif and might give him aid. Kara Buga entered the city on a sudden and cut down the people on all sides. Bahadur Ali, governor of Bagdad, went hither also with the troops in his garrison. These two commanders after joining their forces near Anbar encountered the new Kalif who, ranging the Turkmans on his right, the Arabs on his left, charged himself in the center. Bahadur’s troops took to flight and the greater part threw themselves into the river. Kara Buga put some of his forces in ambush and waited. When the Turkmen and Arabs met the Mongols they fought very little, and rushed off in panic. The center, now left unsupported, was surrounded and overpowered, crushed into disorder and cut to pieces. The Kalif was lost in that chaos, and was never seen again. According to some he was killed, others said that he escaped to Arabs and died of his wounds while among them.
