沮渠蒙遜
In 413, Tufa Rutan launched yet another campaign against Northern Liang, and was again defeated. Juqu Mengxun again put Ledu under siege but could not capture it. However, Tufa Rutan's general Tufa Wenzhi (禿髮文支) then rebelled, encouraging Juqu Mengxun to launch a new attack. Tufa Rutan was forced to send his brother Juqu Juyan to Northern Liang as a hostage.
