Tangut Military Campaigns (1120s)

Timeline

1. 1123Hetao region · Inner MongoliaWestern Xia's Emperor Chongzong Li Qianshun again sent troops to aid Liao, seeking to maintain ties with Liao's remaining forces. Jin generals including Wanyan Wolibu intercepted the Xia army near the Yishui River; Western Xia was defeated, its Liao-aid strategy frustrated, pushing it further toward accommodation with Jin.
2. 1126Huaide Army · NingxiaAs Northern Song faced the crisis of the Jin advance south, Western Xia launched a major offensive, capturing Tiande, Yunnei, Wuzhou, and the Eight Hostels of Hedong, and taking Zhenwei Fortress, Xi'an Prefecture, and the Jianning Stockade of Linzhou. In the eleventh month they massed heavy forces to besiege Huaide Army; defenders Liu Quan and Du Yi held for over a month before the city fell and they died for the cause, costing Northern Song the key strongholds of the Hengshan–Tiandu Mountain defense line built over thirty years.
3. 1127–1128Dingbian Army · ShaanxiAfter Jin ceded northern Shaanxi to Western Xia, Tangut forces continued encroaching eastward, capturing Song positions such as Dingbian Army and Dejing Stockade in 1128, further squeezing Northern Song's remaining northwestern holdings; the Song-Xia war effectively ended with the fall of Northern Song.
