First Siege of Jinju: The Defiant Stand of 1592
In the autumn of 1592, the course of the Imjin War—the Japanese invasions of Korea—was fundamentally challenged at the gates of Jinju Fortress. What began as a Japanese strategic move to secure a route into the wealthy Jeolla province turned into a desperate, bloody struggle that would ultimately boost Korean morale and halt a major military advance.
The siege, which took place from November 8 to November 13, 1592, pitted a massive Japanese force against a vastly outnumbered Korean garrison. Despite the overwhelming odds, the defenders of Jinju achieved a victory that remains one of the most significant land battles of the conflict.

Strategic Background and Objectives
Jinju Fortress held immense strategic value as it guarded the entrances to the Jeolla province. For the Japanese commanders, Ukita Hideie and Hosokawa Tadaoki, capturing the fortress was essential to opening a new path into Jeolla, a region known for its abundant resources and loot. Furthermore, controlling Jinju would allow them to suppress the Righteous armies—local guerrilla forces led by figures like Gwak Jae-u who were resisting the invasion.
To achieve this, a massive Japanese contingent of approximately 30,000 soldiers was mobilized, tasked with capturing both the small fortress of Changwon and the primary stronghold at Jinju.
The Siege: A Battle of Attrition
When the Japanese Seventh Contingent arrived at Jinju on November 8, they expected a swift victory. However, the Korean defense, led by General Kim Si-min, was prepared. Although the Korean forces were significantly outnumbered, Kim Si-min had recently acquired roughly 170 arquebuses—early firearms similar to the Japanese matchlocks—and had ensured his men were well-trained in their use.
The Japanese Assault
The Japanese forces employed various siege tactics, including the use of ladders to scale the walls and siege towers to gain height. They attempted to use their own arquebuses to provide cover for the climbing soldiers. However, the Korean defenders countered these efforts with massive volleys of cannons, arrows, and bullets. The defenders used rocks and axes to smash incoming ladders, and the use of mortars from the fortress walls caused significant Japanese casualties.
Historical accounts, such as those in the Taikōki, describe the intense struggle on the ladders. One notable account mentions Hosokawa Tadaoki's brother, Sadaoki, attempting to lead a climb personally to inspire his men. Despite his bravery, he was repelled by Korean spears and naginata (a polearm with a curved blade) and fell into the moat.
The Turning Point and Reinforcements
The battle took a critical turn on the third day when General Kim Si-min was wounded by a bullet to the side of his head. Despite the loss of their commander and dwindling ammunition, the Korean garrison refused to surrender. The arrival of Gwak Jae-u and his band of irregulars provided the necessary distraction. Although his force was small, the noise of horns and the sudden appearance of approximately 3,000 guerrillas caused the Japanese commanders to realize the danger of their position, prompting a retreat.

Legacy of the Battle
The First Siege of Jinju is celebrated alongside the Battle of Hansan Island and the Battle of Haengju as one of the three most important victories of the Imjin War. While the Japanese would return in the summer of 1593 to burn Jinju to the ground during a second siege, the initial victory provided a vital psychological boost to the Korean resistance.
