沮渠蒙遜
In 410, one of Tufa Rutan's campaigns would hurt him greatly. He attacked Northern Liang and forced 1,000 households to move to his state. In retaliation, Juqu Mengxun pillaged a larger number of households from his state, and when Tufa Rutan's brother Tufa Juyan responded, Juqu Mengxun defeated him. When Tufa Rutan himself followed with a larger force, Juqu Mengxun defeated him as well, and then advanced on Guzang and put it under siege. The residents of Guzang, remembering the massacre that Tufa Rutan carried out during Wang Zhong's rebellion, panicked, and a large number surrendered to Juqu Mengxun. With his general Zhequ Qizhen (折屈奇鎮) also rebelling to the south, Tufa Rutan became apprehensive, and moved the capital from Guzang back to Ledu. The general Jiao Lang quickly rebelled and held Guzang, although Juqu Mengxun conquered it in 411, and then advanced on Ledu, sieging it for more than a month before Tufa Rutan submitted by sending his son Tufa Anzhou (禿髮安周) to Juqu Mengxun as a hostage.
