While seeking help from the Ming Dynasty, the Korea also gathered all the Korean troops to resist. However, the Japanese army successively occupied several major cities. As one of the strategic places connecting the north and the south, Haengju must be defended. The commander of Korean army, Gwon Ryul, decided to lead 4,000 elite soldiers to hold the Mountain City, Haengju. At dawn on February 12th, 1593, over 30,000 Japanese troops arrived in front of Haengju. The Japanese troops scattered to attack the city over and over. The fierce battle lasted until dusk. The two-layered Castle fences built by Haengju were defeated by the Japanese army's continuous attacks. On the last defensive line of the city wall, Gwon Ryul repelled the enemies and successfully defended Haengju. With his military talent, Gwon Ryul resisted the Japanese's invasion and became the famous patriotic hero of Korea.
