Kwŏn Yul (general)

Kwŏn Yul (general)

Kwŏn Yul (28 December 1537 – 6 July 1599) was a Korean army general who served as the commander-in-chief of Joseon forces during the Japanese invasions of Korea. He is most famous for the Battle of Haengju, where his 2,800 troops defeated a Japanese force of about 30,000.

Kwŏn came from the prominent Andong Kwŏn clan; his father, Kwŏn Ch'ŏl, had been the yeonguijeong. Despite this background, Kwŏn did not enter government or military service until he was 46. He received his first official post in 1582 and held several positions, including mayor of Uiju in 1591.

When the Japanese invaded in 1592, Kwŏn was mayor of Gwangju in Jeolla province and held military command there. He joined his superior Yi Kwang in a march toward Seoul, but after Yi was defeated at Yongin, Kwŏn retreated to Gwangju and gathered about 1,000 militia. At the Battle of Ichi, Kwŏn’s roughly 1,000 men faced 10,000 Japanese troops under Kobayakawa Takakage and won, securing the recapture of Jeolla province. Kwŏn personally executed deserters to maintain discipline, and his vanguard commander Hwang Chin fought on despite a gunshot wound.

In 1593, Kwŏn was named governor of Jeolla. He led 10,000 troops toward Gyeonggi Province, gathering local militia and monks to reach about 20,000 men. At Doksan Fortress near Suwon, Japanese forces under Ukita Hideie besieged him for a month. Running low on water, Kwŏn ordered war horses brought onto the fort wall and washed with grains of rice. From a distance, the Japanese believed the fort had ample water, lost morale, and retreated to Seoul. Kwŏn pursued them, inflicting over 3,000 casualties. King Seonjo later erected a monument called Semadae at Doksan to honor the ruse.

Kwŏn then set up camp at the ruined Haengju fortress near Seoul with no more than 2,800 men, joined by local militias and monk soldiers. Japanese commanders Katō Kiyomasa and Ukita Hideie attacked with 30,000 troops on 12 February 1593. Kwŏn’s forces and civilians defended with rocks, arrows, iron pellets, burning oil, molten iron, hwachas, and explosive cannon shells. The Japanese suffered over 10,000 casualties, and top generals Ukita, Ishida Mitsunari, and Kikkawa Hiroie were wounded, forcing a retreat.

Kwŏn remained in his post until peace talks between the Ming emperor and Toyotomi Hideyoshi began, then moved to Jeolla and was appointed Dowonsu, commander-in-chief. He was briefly removed for harsh treatment of deserters but reinstated the following year. He ordered Admiral Wŏn Kyun into battle at Chilchonryang, which ended in Japanese victory, though Yi Sun-sin later defeated the Japanese at Myeongnyang. In 1597, Kwŏn and Chinese commander Ma Gui planned to attack the Japanese at Ulsan, but the Chinese commander-in-chief ordered a withdrawal. A later plan to strike Suncheon was also rejected by the Chinese.

After the war, Kwŏn retired from all posts and died on 6 July 1599. He was posthumously granted the title of Yeonguijeong and named an Ildŭng Sŏnmu Kongsin alongside Yi Sun-sin and Wŏn Kyun.

Lore & Background

Kwŏn Yul hailed from the prestigious Andong Kwŏn clan; his father, Kwŏn Ch'ŏl, was the yeonguijeong. He did not begin his political or military career until he was 46. In 1582, he was first appointed to a position in the Korean government and promoted to several different positions including the mayor of Uiju in 1591. When the Japanese forces invaded Korea in 1592, Kwŏn was appointed the mayor of Gwangju, Jeolla province and given the military command of the region. At the Battle of Ichi, about 1,000 of Kwŏn's men fought and won against ten thousand Japanese troops under Kobayakawa Takakage. Kwŏn supervised his unit by executing deserters personally, and his vanguard commander Hwang Chin kept fighting despite a gunshot injury. At the Siege of Doksan, Japanese forces led by Ukita Hideie laid siege to the fort for one month, and Kwŏn's army was running out of water supplies. One day, Kwŏn ordered several war horses to be brought on the fort wall and washed with grains of rice. From a distance, it looked like the horses were bathed with plenty of water. The Japanese, who were waiting for the fort's water supply to run out, lost their spirits and retreated to Seoul. Kwŏn chased the retreating Japanese, inflicting heavy casualties of over 3,000 men. After the war, the king Seonjo built a monument on the top of Doksan named Semadae (세마대; 洗馬臺), 'the place where horses were washed', as a tribute to Kwŏn. At the Battle of Haengju, Kwŏn's entire unit was no more than 2,800 men. Japanese commanders Katō Kiyomasa and Ukita Hideie attacked Haengju fortress with 30,000 men. The Japanese, with over 10,000 casualties and top generals Ukita, Ishida Mitsunari, and Kikkawa Hiroie wounded, were compelled to retreat. After the battle, he kept his position until the peace talks began. Then he moved to Jeolla province, and from then on, Kwŏn Yul became the Dowonsu, the Commander-in-chief of Korean forces. He was briefly removed from office due to his harsh treatment of deserters, but was restored back again in the following year. He ordered the Admiral of the Navy, Wŏn Kyun, to battle the Japanese in the Battle of Chilchonryang, which was won by Japanese. However, Admiral Yi Sun-sin was able to defeat the Japanese navy under Todo Takatora in the Battle of Myeongnyang. In 1597, Kwŏn and the Chinese commander Ma Gui planned to combat the Japanese in Ulsan, but the Chinese commander-in-chief ordered Kwŏn to withdraw. Then Kwŏn tried to attack the Japanese in Suncheon, but the idea was again rejected by the Chinese. After the war, Kwŏn retired from all of his posts and eventually died on July 6, 1599. After his death, he was given the posthumous title of Yeonguijeong, and awarded the title of the Ildŭng Sŏnmu Kongsin (일등선무공신; 一等宣武功臣) along with Yi Sun-sin and Wŏn Kyun.

Reader's Guide

Kwŏn Yul's significance lies in his decisive victories during the Japanese invasions of Korea, which helped preserve Joseon independence. His most famous achievement, the Battle of Haengju, demonstrated exceptional defensive tactics against overwhelming odds, using Korean anti-personnel gunpowder weapons called hwachas and explosive cannon shells called heaven-shaking explosive shell (비격진천뢰; 飛擊震天雷). The Siege of Doksan showcased his psychological warfare, tricking the Japanese into believing his fort had ample water by washing horses with grains of rice on the fort wall. His career, beginning late in life at age 46, illustrates that effective military leadership could emerge from non-traditional paths. Kwŏn's legacy is cemented by posthumous honors: he was granted the title of Yeonguijeong and named Ildŭng Sŏnmu Kongsin alongside Yi Sun-sin and Wŏn Kyun. The monument Semadae at Doksan remains a tribute to his cunning. His actions, including personally executing deserters at the Battle of Ichi, reflect the harsh realities of wartime command. Kwŏn's role in coordinating with Chinese forces, though sometimes overruled—such as when the Chinese commander-in-chief ordered him to withdraw from Ulsan in 1597—shows the complex alliance dynamics of the conflict. Overall, he is remembered as a key defender of Korea during a critical period.
