Li Rusong vs Sun Chuanting

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.

Sun Chuanting was appointed Minister of War by the Chongzhen Emperor, tasked with suppressing the peasant rebellions. He implemented strategies to coordinate regional forces but faced chronic shortages of funds and troops, limiting his effectiveness.

Sun Chuanting led Ming forces against Li Zicheng's rebel army at Zhu Xian Zhen in Henan. His army was defeated due to lack of reinforcements and supplies, resulting in heavy losses and the collapse of Ming defenses in the region.

Sun Chuanting attempted to hold Tongguan Pass against Li Zicheng's advancing forces. He was defeated and killed in battle, and the pass fell, opening the way for Li Zicheng to march on Beijing and ultimately overthrow the Ming dynasty.
