Li Wenzhong vs Tong Guan

Li Wenzhong, as a nephew and general of Zhu Yuanzhang, participated in the capture of Chuzhou and other key cities in the early Red Turban Rebellion. These victories helped establish Zhu's base in the Yangtze River region.

Li Wenzhong commanded a fleet that contributed to the decisive Ming victory over the rival rebel leader Chen Youliang at Lake Poyang. This battle eliminated Zhu Yuanzhang's main rival and paved the way for Ming unification.

Li Wenzhong was a key commander in the Ming army that captured Dadu, the Yuan capital, forcing Emperor Toghon Temur to flee. This event marked the formal establishment of the Ming dynasty over China.

Li Wenzhong led several military expeditions into Mongolia against the retreating Northern Yuan forces. He achieved victories at Yingchang and other locations, but failed to completely destroy the Mongol threat.

Tong Guan commanded a Song army against the Western Xia (Tangut) state, achieving initial victories but failing to secure lasting gains. The campaign drained resources and exposed military weaknesses.

Tong Guan negotiated the 'Alliance Conducted by Sea' with the Jurchen Jin dynasty, agreeing to jointly attack the Liao dynasty. The alliance aimed to recover the Sixteen Prefectures but led to Jin expansion.

Tong Guan was placed in charge of defending Kaifeng against the Jin invasion but proved incompetent. He failed to coordinate defenses and fled, contributing to the fall of the Northern Song capital.

After the Jin siege of Kaifeng, Emperor Qinzong ordered Tong Guan's execution for treason and incompetence. He was beheaded, and his death was seen as a scapegoat for the dynasty's collapse.
