Li Gao - Late Reign

Late Reign

In 408, not having received response from Jin when he sent messengers in 405, Li Gao sent another messenger with his petition to the Jin capital Jiankang (建康, modern Nanjing, Jiangsu).

In 410, Juqu Mengxun attacked Western Liang again and defeated Li Gao's heir apparent Li Xin in battle, capturing the general Zhu Yuanhu (朱元虎). Li Gao ransomed Zhu with silver and gold, and Juqu Mengxun returned Zhu and made peace with Li Gao.

In 411, Juqu Mengxun, despite the prior peace agreement, made a surprise attack on Western Liang. Li Gao guarded his capital and refused to engage Juqu Mengxun, who was then forced to withdraw when his army ran out of food supply. Li Gao then sent Li Xin to attack the Northern Liang troops in retreat, and Li Xin had a major victory over Juqu Mengxun, capturing his general Juqu Bainian (沮渠百年).

In 416, Li Gao's subordinate Suo Chengming (索承明) suggested that he attack Northern Liang. Li Gao summoned Suo and explained to him that he had insufficient strength to do so—and that Suo, if he hactually had usable plans, should offer them rather than simply suggesting an attack. In fear and shame, Suo withdrew from his presence.

In 417, Li Gao grew ill, and he entrusted Li Xin to his brother Song Yao, stating, "After I die, the heir apparent is your son. Please discipline him accordingly." He then died, and Li Xin succeeded him as duke. Although Li Gao only claimed a ducal title, he was posthumously honored as a prince.
