14 March 1273
Southern Song commander Lü Wenhuan surrendered Xiangyang on 14 March 1273, after Mongol forces moved the siege engines used against Fancheng into position against his city.
According to the Yuan dynastic history, a projectile struck Xiangyang's watchtower with a thunderous report, panic spread, and some officers defected over the walls.
What ended the siege, which had run since 1268, was a negotiated surrender rather than a final storming.
The broken arrow
The Mongol commander Alihaiya offered Lü safety and advancement, then broke an arrow as an oath guaranteeing the terms. Lü ultimately accepted and capitulated.
Fancheng had already fallen and its population had been massacred; about 10,000 bodies were reported piled outside it, and relief was no longer credible.
The capitulation ended the Xiangyang–Fancheng operation without a second massacre.
What the siege actually introduced
This was not the first combat use of firearms. Gunpowder weapons were used in China centuries earlier — a Cambridge history timeline records a fire-spear at De'an in 1132.
The decisive new technology was the counterweight trebuchet, brought into this theatre by engineers connected with the Ilkhanate, Ismaʿil and ʿAla' al-Din.
Xiangyang passed intact into Mongol hands and Lü Wenhuan entered Yuan service, opening an operational route toward the Yangtze — though not immediate control of it.

What the sources leave uncertain
- Modern works consistently convert Lü’s surrender date to 14 March 1273, although the underlying Chinese record uses regnal and lunisolar dating.
- Names vary by transliteration: Lü/Lu, Aju/Achu, and Alihaiya/Ariq-Qaya. Accounts that simply say Lü surrendered to Aju blur the distinction between overall command and the commander who negotiated the capitulation.
- Sources describe the operation as lasting either about five elapsed years or six years by inclusive reckoning.
