Daemusin of Goguryeo vs Zhizhi Chanyu

Daemusin personally killed the king of Dongbuyeo during a battle, a rare feat for a monarch. This act decisively ended the war and led to the annexation of Dongbuyeo into Goguryeo, greatly expanding its territory.

Following the death of its king, Daemusin incorporated Dongbuyeo into Goguryeo. This doubled Goguryeo's territory and population, transforming it from a small kingdom into a major regional power in Manchuria and northern Korea.

Daemusin launched a military campaign to subjugate the Okjeo tribes along the eastern coast of the Korean peninsula. The campaign succeeded in bringing these tribes under Goguryeo's control, securing valuable coastal resources and trade routes.

Zhizhi and his brother Huhanye fought for control of the Xiongnu confederation. Zhizhi defeated Huhanye initially, but Huhanye submitted to the Han dynasty, gaining their support. Zhizhi then moved west, splitting the Xiongnu.

After moving west, Zhizhi Chanyu attacked the Wusun people and allied with the Kangju. He established a base in the Talas River valley, raiding neighboring tribes and disrupting trade routes, which provoked Han intervention.

Zhizhi Chanyu, having moved west into Central Asia, was attacked by a Han Chinese expeditionary force led by Chen Tang and Gan Yanshou. His fortified city was stormed, and Zhizhi was killed. This battle marked the furthest westward expansion of Han military power and ended Zhizhi's threat to the Han.
