Mongols open the assault on Baghdad’s walls
Reconstructed from historical sources
The Mongols have walled Baghdad in and shut the Tigris with bridges of boats; on Tuesday their catapults opened on the Ajami Tower, and the Khan has sent the caliph’s vizier back, demanding the vizier, Sulaymanshah and the Dawatdar together.

BAGHDAD, Wednesday.—Baghdad is walled in by the Mongols and the Tigris is shut, and on Tuesday, the twenty-second of Muharram, the Mongol army began to fight.
The siege lines came first. The host that has ringed the city since the middle of the month has set up a wall of its own around Baghdad’s ramparts, and the Khan’s men stand guard an arm’s length from the city wall, so that no one gets out.
By the Khan’s order, bridges have gone across the river above and below the city, boats have been made ready, catapults set up and guards posted.
Baiju’s troops tied the pontoon bridges. Between the surface and the river bed they have sunk stout fences with iron hooks and pipes, so that no one can so much as swim out of the city unseen.
Downstream, a tümen, a division of ten thousand men, patrols the routes south to Madayin and Basra to stop anyone escaping by boat.
Then, with Aries in the ascendant, the attack opened. Hülegü Khan holds the centre himself, on the Khurasan road side of the city, opposite the Ajami Tower on the east wall. His princes and commanders hold posts all round the city.
Catapults have been set up facing the Ajami Tower, and they are at work against it.
