李如松
The Japanese invasion into Jeolla province was broken down and pushed back by General Kwon Yul at the hills of Ichiryeong, where outnumbered Koreans fought Japanese troops in the Battle of Byeokjegwan and gained a victory. Kwon Yul quickly advanced northwards, re-taking Suwon and then swung north toward Haengju where he would wait for Chinese reinforcements. After he was informed that the Ming army under Li Rusong was pushed back at Byeokje, Kwon Yul decided to fortify Haengju. Kwon's force of 2,300 men were a mixture of regulars, warrior monks, and Righteous Army guerrillas.
