Xiangyang Fortress Defense System

Timeline

1. c. 1127–1210Xiangyang Prefecture · Hubei ProvinceAfter the Jingkang Incident the Southern Song established its capital at Lin'an; Xiangyang–Fancheng, a twin-city fortress on the middle Han River, became the western anchor of the Song-Jin border. Defenses combined brick-faced rammed-earth walls, moats, and the Han River waterway, with heavy garrisons shielding Jingxiang and the lower Yangtze. After the Mongols attacked Jin in 1211, Xiangyang became an outpost monitoring the north.
2. 1267–1273Xiangyang–Fancheng defense system · Hubei ProvinceIn 1267 the Mongols and Southern Song launched a prolonged siege of Xiangyang, both sides committing large forces and siege engines. Defender Lü Wenhuan led troops and civilians in a six-year resistance, the defense system holding out with river pontoon bridges, ballistae, and supply lines, until the city fell in 1273, opening the gateway to the Southern Song's Yangtze defense line.
3. 1273Old city of Xiangyang · Hubei ProvinceAfter the city fell, Xiangyang was incorporated into the Yuan realm; its walls were repeatedly repaired in the Ming and Qing. The surviving old walls and the memory of the Song-Yuan War stand as key witnesses to the history of ancient Chinese river-fortress defense and the turning point from Song's fall to Yuan's rise.
