The casualties mounted; Yaʿqūb broke and fled, his commanders were wounded, his treasuries were lost, and a number of his men drowned in the river (1).
Abu al-Saj (2) said to Yaʿqūb, “I have seen nothing of military planning on your part (3); how then did you defeat people? You left your baggage‐train and prisoners ahead of you, marched toward a land whose rivers and fords you did not know (4), hurried forward, and your troops were in disarray!”
Yaʿqūb replied, “I never imagined I would have to fight, nor did I ever doubt victory.”
Abu al-Faraj al-Isbahani relates: Yaʿqūb’s letters kept reaching al-Muʿtamid in evasive language, saying, “I am certain that the Commander of the Faithful has set out only to honor me and come forth to receive me.”
Al-Muʿtamid repeatedly sent urging him to withdraw, but to no avail. The caliph then mustered his forces and flooded the roads with canal water; that proved the cause of Yaʿqūb’s defeat. People imagined his retreat to be a stratagem and therefore did not pursue him. Ibn Ṭāhir slipped away and, still in chains, appeared before al-Muʿtamid.
Part of Yaʿqūb’s army consisted of Christians, and the battle took place in Rajab of the year 262 AH.
Yaʿqūb then moved to Wāsiṭ and from there to Tustar, which he captured. His army regrouped, his might grew formidable, and he was on the verge of mastering the world. Yet he died of colic; a clyster was prescribed for him but he refused it, and he perished after a fortnight.
Al-Muʿtamid had already dispatched an envoy to conciliate him and win his goodwill, and the ʿAlid ruler of Jurjān used to call him “Yaʿqūb the Anvil” because of his steadfastness.
He was seldom seen smiling.
He died at Gundeshapur in 265 AH.
