The History of Geumsan Fortress (Kimsanseong) and its Significance as a Battlefield in the Imjin War
Overview and Definition of Geumsan Fortress
Geumsan Fortress (Kimsanseong, Geumsanseong) was an important military base during the Joseon Dynasty, located in present-day Geumsan County, Chungcheongnam-do. This fortress played a historically significant role as a strategic point in the central region of the Korean Peninsula, particularly during the Imjin War (Japanese invasions of Korea, 1592-1598).
The name Geumsan means “a mountain as beautiful as brocade,” and this region has long been known as a transportation hub. Located on an important route connecting Jeolla Province and Chungcheong Province, it possessed extremely high military value and was a strategically important base for both the Japanese and Korean armies.
Geographical Importance of Geumsan Fortress
Geumsan Fortress was located in the central-western part of the Korean Peninsula and was a strategic point controlling the access route to Jeolla Province. The Japanese army needed to pass through Geumsan to invade Jeolla Province, and therefore fierce battles for its control raged from the early stages of the Imjin War. The mountainous terrain surrounding the castle offered advantageous defensive positions, but also presented challenges in securing supply routes.
Historical Background of Geumsan Fortress
From the Three Kingdoms Period to the Joseon Dynasty
The Geumsan region has been inhabited since ancient times and belonged to the Baekje territory during the Three Kingdoms period. Some historical records refer to it as “Geumhyeonseong,” suggesting it may have functioned as a mountain fortress during the Baekje era. According to the Encyclopedia of Korean Folk Culture by the Academy of Korean Studies, mountain fortresses in this region were recognized as strategically important locations from ancient times.
After the Unified Silla period, and into the Goryeo Dynasty, Geumsan developed as a center of local administration. During the Joseon Dynasty, Geumsan County was established, becoming the administrative and military center of the region. During this period, Geumsan Fortress was maintained as an important base for local defense.
Geumsan Before the Imjin War
Before the outbreak of the Imjin War, Geumsan was a relatively peaceful provincial city. Agriculture and commerce were well-developed, and its location on the trade route connecting Jeolla Province and Chungcheong Province made it an economically important region. However, this peace was acute by the Japanese invasion of 1592.
The Imjin War and the Battle of Geumsan
First Battle of Geumsan (July 9-10, 1592)
In July 1592 (the 25th year of King Seonjo’s reign), shortly after the start of the Imjin War, the main force of the Japanese army, led by Kobayakawa Takakage, attacked and occupied Geumsan Castle. Kobayakawa Takakage was a trusted general of Toyotomi Hideyoshi and was aiming to invade Jeolla Province with approximately 10,000 troops.
The fall of Geumsan Castle was a serious matter for the Korean side. Jeolla Province was the granary of Korea, and if this region fell into the hands of the Japanese army, the overall resistance capacity of Korea could be severely impaired. Therefore, the Korean side made the recapture of Geumsan Fortress their top priority.
Go Gyeong-myeong’s Righteous Army Uprising
Go Gyeong-myeong (1533-1592), a Confucian scholar and influential local figure in Jeolla Province, organized a righteous army in response to the national crisis. Go Gyeong-myeong had served as the governor of Dongnae Province as a member of the Western Faction, and had retreated to the provinces after the Western Faction’s downfall following Jeong Cheol’s “Geonchoui Incident.”
Go Gyeong-myeong gathered approximately 6,000 righteous soldiers from various parts of Jeolla Province and marched toward recapturing Geumsan Fortress. However, the First Battle of Geumsan, fought from July 9th to 10th, resulted in a defeat for the Korean righteous army against the overwhelming firepower and tactics of the Japanese army, with many soldiers, including Go Gyeong-myeong, being killed. ### Second Battle of Geumsan (August 18, 1592)
Despite the defeat in the First Battle of Geumsan, the Korean side continued its efforts to recapture Geumsan Castle. At this time, the central figures were the righteous army commander Cho Heon (1544-1592) and the warrior monk commander, Master Yeonggyu.
Cho Heon’s Righteous Army Activities
Cho Heon was a Confucian scholar and a known disciple of Toegye Yi Hwang. He organized righteous army forces at the outbreak of the Imjin War and carried out resistance activities in various locations. Cho Heon possessed high moral authority, and many Confucian scholars and common people gathered under his banner.
Cho Heon led approximately 700 righteous army men toward Geumsan. Although this force was overwhelmingly smaller than the Japanese army, Cho Heon was determined to fight for “righteousness.” It is said that before going into battle, he told his righteous army soldiers, “Today’s battle is not about survival, but a battle in which we will sacrifice our lives for our country.”
The Monk Soldiers of Master Yeonggyu
Master Yeonggyu was a high-ranking monk of Korea who organized monk soldiers to resist during the Imjin War. While Buddhist precepts prohibit killing, Master Yeonggyu decided to take up arms to protect his country and people. His army joined of approximately 500 monk soldiers who joined forces with Jo Heon’s righteous army to participate in the attack on Geumsan Fortress.
Fierce Battle and Annihilation
On August 18, 1592, the combined forces of Jo Heon and Master Yeonggyu, numbering approximately 1,200, launched an attack against the Japanese army of approximately 10,000 defending Geumsan Fortress. This battle is recorded as one of the most tragic battles in the history of Korean righteous armies.
The righteous army fought bravely, but the disparity in troop numbers and weaponry could not be overcome. The Japanese army effectively used firearms (matchlock guns), inflicting heavy losses on the righteous army. After a fierce battle that lasted all day, almost all of the righteous army, including Cho Heon and Master Yeong Gyu, were killed.
While this battle was a complete military defeat, the righteous army’s self-sacrificing spirit had a profound impact on later generations. The actions of Cho Heon and others became a catalyst for the expansion of the righteous army movement throughout Korea, and ultimately one of the driving forces behind the Japanese army’s withdrawal from the peninsula.
Military Historical Analysis of the Battle of Geumsan
Tactical Analysis
A military historical analysis of the Battle of Geumsan yields several important lessons. Firstly, the difference in troop strength and the quality of weaponry had a decisive impact on the battle’s outcome. The Japanese army possessed advanced firearm units for the time, enabling them to inflict heavy losses on the Korean righteous army before engaging in close combat.
Secondly, the superiority of fortified defense was clearly demonstrated. The attacking Korean righteous army was unable to penetrate the Japanese army’s defensive positions. In medieval castle warfare, the attacking side typically required more than three times the number of troops, but in the Battle of Geumsan, the defending side had nearly ten times the number of troops.
Thirdly, there is the importance of supply and logistics. The righteous army was forced into a short, decisive battle, while the Japanese army had secured a stable supply line using Geumsan Castle as a base.
Strategic Significance
Although tactically it was a defeat, the Battle of Geumsan held significant strategic importance. The righteous army activities of Cho Heon and others delayed the Japanese invasion of Jeolla Province, buying time for resistance to be organized in the region. Furthermore, the sacrificial spirit of the righteous army spread throughout Korea, becoming a catalyst for the revitalization of righteous army movements in various regions.
After the Battle of Geumsan, the Japanese army was forced to temporarily refrain from a full-scale invasion of Jeolla Province. This was due to Yi Sun-sin’s navy controlling the seas and threatening the Japanese supply lines, as well as the disruption of the Japanese rear by righteous army activities in various regions.

Commemoration of Jo Heon
Jo Heon is a representative righteous army general of the Joseon Dynasty and is commemorated throughout the country. In addition to his birthplace in Chungcheong Province, there are monuments and shrines in Geumsan commemorating Jo Heon. Jo Heon is highly regarded from the Joseon Dynasty to the present day as a Confucian scholar who excelled in both literary and martial arts, and as a righteous man who rose selflessly in times of national crisis.
The Joseon Dynasty posthumously bestowed high official ranks upon Jo Heon in recognition of his achievements. Furthermore, his scholarship and thought greatly influenced later Confucian scholars, forming an important lineage of Korean Confucianism.
The Memory of Master Yeonggyu
Master Yeonggyu holds a significant position in the history of Korean Buddhism. His activities as a warrior monk during the Imjin War demonstrate the crucial role that declining Korean Buddhism played in times of national crisis. Master Yeonggyu’s sacrifice is remembered as a symbol of patriotism and the spirit of self-sacrifice within the Buddhist community.
Geumsanseong Fortress and Related Historical Sites
Distinction from Other Geumseongsanseong Fortresses
The names “Geumsanseong” and “Geumseongsanseong” exist in various locations on the Korean Peninsula, so it is necessary to avoid confusion. For example, Geumseongsan Mountain (451m high) in Naju, South Jeolla Province, is known as Naju’s Guardian Mountain and is an isolated mountain consisting of four peaks. Also, Geumseongsanseong Fortress, located on the border between Damyang County in South Jeolla Province and Sunchang County in North Jeolla Province, is a stone fortress considered one of the three major mountain fortresses in the Honam region, and was used for entry after the Goryeo period.
These are separate historical sites from Geumsanseong Fortress in Geumsan, and are geographically and historically distinct. Geumsanseong Fortress in Geumsan holds particular significance as the site of righteous army battles during the Imjin War.
Comparison with Cheongju Fortress
As important battle sites during the Imjin War, Cheongju Fortress and Geumsanseong Fortress are often compared. The Battle of Cheongju Fortress is known as one of the few spectacular for the Korean army, in which a combined force of righteous army and government troops successfully recaptured Cheongju Fortress from the Japanese army in August 1592.
On the other hand, while the Battle of Geumsan Fortress ended in a tragic defeat, its spirit of sacrifice had an impact on later generations of Koreans equal to, or even greater than, the victory at Cheongju Fortress. Both battles are important subjects of military history research, symbolizing the spirit of Korean resistance during the Imjin War.
