Li Hao
In 406, Li Hao entered into a peace agreement with Southern Liang's prince Tufa Rutan, with an implicit understanding of an alliance against Northern Liang, but no actual joint military action was ever taken. Later that year, Juqu Mengxun made an attack on Jiuquan, and Li Hao suffered a defeat to Juqu Mengxun near Jiuquan and was forced to return to the city to defend it against a siege, but Juqu Mengxun, not having enough strength to siege it, withdrew.
