within it; they then set the door of the church on fire, and all of them were burned to the last man. No fortified spot now remained except the place where the deputy Yatis was lodged, an impregnable citadel.
Al-Muʿtasim mounted his horse and rode up until he halted opposite the fortress in which Yatis was quartered. A herald cried out:
“Woe to you, Yatis! The Commander of the Faithful stands before you.”
He replied, “Yatis is not here,” and said it twice. Al-Muʿtasim grew angry and turned away, whereupon (1) Yatis shouted, “Here is Yatis, here is Yatis!” The Caliph returned, had ladders set against the stronghold, and envoys climbed up to him.
They said to him, “Shame on you! Come down and submit to the judgment of the Commander of the Faithful.” He resisted, then descended wearing his sword; he set the sword aside, was brought forward and made to stand before al-Muʿtasim, who struck (2) him on the head with a whip, and then ordered that he walk to the Caliph’s pavilion. He proceeded there in humiliation, to the tent where the Caliph was encamped, and was firmly bound.
The Muslims seized from Amorium immense wealth and booty beyond counting or description. They carried off whatever could be transported, and al-Muʿtasim ordered that whatever remained be burned, together with the mangonels, dabbābāt, and other war machines that were there, lest the Byzantines derive any strength from them in fighting the Muslims. [al-Muʿtasim] (3) then set out, returning toward the district of Tarsus at the end of Shawwal of that year. His stay before Amorium had lasted fifty-five (4)(5) days.
Account of the killing of al-ʿAbbās ibn al-Maʾmūn
Al-ʿAbbās ibn al-Maʾmūn had accompanied his uncle al-Muʿtasim on the Amorium expedition. ʿUjayf ibn ʿAnbasa had reproached him for not seizing the caliphate when his father al-Maʾmūn died at Tarsus, and for having pledged allegiance to his uncle al-Muʿtasim. He persisted until al-ʿAbbās agreed to assassinate his uncle and secure the oath of allegiance from the commanders for himself.
He dispatched a man named al-Ḥārith al-Samarkandī, a boon companion of al-ʿAbbās, who secretly obtained the pledge of allegiance for him from a group of commanders, secured their commitment, and instructed them that whenever (6) he struck down his uncle each should kill whomever he could among al-Muʿtasim’s principal supporters—such as al-Afshīn, Ashnās, and the other grandees. When they were on the Roman Road, making for Ancyra and thence to Amorium, ʿUjayf advised al-ʿAbbās to kill his uncle in that narrow defile, claim the pledge for himself, and return to Baghdad.
Al-ʿAbbās replied, “I would hate to deprive the people of this expedition.” After Amorium was taken and the troops were busy with the spoils, he again urged him to assassinate
