Li Rusong
Supreme Commander of the Ming expeditionary army
"Korea is the fence of Liaodong, and Liaodong is the arm of Beijing."
Biography
The son of the great frontier general Li Chengliang and a veteran of the Ningxia rebellion, Li Rusong brought 43,000 Ming troops into Korea in the winter of 1592 with something neither Korea nor Japan had: a proper siege train of heavy cannon. At Pyongyang he blasted the walls, drove Konishi's starving division out into the snow, and retook the north in days. Then he outran his artillery. Pushing toward Seoul with his cavalry ahead of the guns, he was ambushed in narrow muddy ground at Byeokjegwan by a much larger force and barely escaped with his life. He pulled back to Kaesong and refused to fight again, preferring negotiation — and the war froze for four years. He had proved the Japanese could be beaten with guns and then demonstrated what happened without them, in the space of seven weeks. He is a contested figure in Korea: he saved the country and he also treated it as a Ming protectorate, was contemptuous of Korean commanders, and let his troops live off a land already stripped bare. He was killed fighting Mongols on the northern frontier in 1598, months before the war he had frozen finally ended.

The Ming campaign in Korea cost roughly ten million taels of silver — a debt the dynasty never recovered from, and one historians still cite among the reasons it fell to the Manchus fifty years later.
Key Battles
The Recapture of Pyongyang
Joseon Korea & Ming China victoryJanuary 8, 1593 · 12,000 total casualties
The moment the war became a world war. The Ming came because Korea was the shield of Beijing — Hideyoshi had announced he was coming for China and they believed him. Chinese artillery answered Japanese arquebuses, and the strategic balance flipped. It also nearly bankrupted the Ming: the campaign cost roughly ten million taels, a debt the dynasty never recovered from and which historians still cite among the causes of its collapse fifty years later.
Battle of Byeokjegwan
Toyotomi Japan victoryFebruary 27, 1593 · 6,000 total casualties
The battle that froze the war. Li had beaten the Japanese when he had his guns and lost the moment he outran them, and thereafter he refused to fight again — settling into negotiation while the Japanese held the south. Byeokjegwan bought Japan four years of stalemate and turned a war of movement into a war of fortresses, famine, and talks that neither side conducted in good faith.
