Li Gao
In spring 411, with Jiao Lang still holding Guzang, Juqu Mengxun sieged Guzang and captured him, but pardoned him. He left Juqu Ru in command at Guzang and then attacked Southern Liang, putting Ledu under siege, and only withdrew after Tufa Rutan sent his son Tufa Anzhou (禿髮安周) as a hostage. Tufa Rutan soon counterattacked, however, and initially was successful, but Juqu Mengxun trailed Tufa Rutan's forces and defeated him, again putting Ledu under siege and forcing Tufa Rutan to send another son, Tufa Ran'gan (禿髮染干) as a witness before withdrawing. In fall 411, Juqu Mengxun made a surprise attack on Western Liang, but was unsuccessful, and as he ran out of food supplies and withdrew, Li Gao sent Li Xin to attack him, defeating him.
