Li Rusong vs Yang Ye

Li Rusong was appointed supreme commander of the Ming expeditionary force sent to aid Joseon Korea against the Japanese invasion led by Toyotomi Hideyoshi. He led a combined Chinese-Korean army to counter the Japanese advance.

Li Rusong led the Ming-Joseon forces in a decisive assault on Pyongyang, which was occupied by Japanese troops. The battle resulted in the recapture of the city and inflicted heavy casualties on the Japanese army, marking a turning point in the war.

Li Rusong's forces were ambushed and defeated by a Japanese army at Byeokjegwan near Seoul. Li himself was wounded in the battle. This setback forced the Ming army to retreat and temporarily halted their advance southward.

Following the military stalemate, Li Rusong participated in negotiations with Japanese representatives for a ceasefire. The talks led to a temporary halt in hostilities and the withdrawal of Japanese forces from the Korean peninsula to the southern coast.

Li Rusong was recalled to China after the ceasefire. His recall was due to political rivalries at the Ming court and disagreements over war strategy. He was replaced by other commanders for the later phases of the Imjin War.

Yang Ye defected from the Northern Han kingdom to the Song dynasty after the Song conquest of Taiyuan. He was appointed as a general in the Song army, bringing his military experience to the Song's campaigns against the Liao.

Yang Ye commanded a Song army at the Battle of the Qigou River against the Liao. After being ordered to advance by the main commander Pan Mei, Yang Ye's forces were surrounded and defeated. He was captured and died shortly after, reportedly by suicide.
