What was the Battle of Chungju (1592)?


The Battle of Chungju or the Battle of Tangeumdae was the last battle of the Chungju Campaign fought between the Koreans and Japanese during the Japanese invasion of Korea in 1592. Chungju is located just south of the Han River and Seoul, Korea’s capital. The defeat of the Korean forces at Chungju led directly to the capture of the capital of Hanseong by Japanese forces shortly thereafter.


On receiving word of the Japanese invasion, and the fall of Busan and Dongnae to the Japanese, the Joseon court under King Seonjo took belated steps to appoint generals and to strengthen defences on the approaches to the capital at Hanseong (present-day Seoul). Knowing that geography would dictate that the Japanese would follow one of three possible routes through the mountains to reach Hanseong, the central (and most direct) route was given the highest priority and its defence was assigned to Yi II and Sin Rip. Both generals had distinguished careers fighting the Jurchen to the north, but were hampered by lack of manpower, as the official military lists of soldiers were filled with missing men or untrained conscripts. Shin Rip was authorised to recruit the Naegeumwi Royal Guards into his forces and was personally given a sword by the king.

Shin Rip assembled his forces at Chungju, consisting of approximately 8000 men. Many of these soldiers had fled from previous engagement with the Japanese at Dongnae, Daegu, and other locations to the south. His original plan was to fortify Choryong Pass, where the terrain could be used to good advantage against the numerically superior Japanese. However, the sudden appearance of General Yi II, minus his armour, horse, and army fresh from defeat at the Battle of Sangju cancelled these plans, as the Japanese army under Konishi Yukinaga was already approaching the pass. Shin Rip then decided to meet the Japanese out on the flat plains near Chungju with his back to the Han River. On one hand, the flat plains would give an advantage to his cavalry, but on the other hand, the Han River made retreat impossible.

In the meantime, a second Japanese army of approximately 20,000 man under the command of Kato Kiyomasa had caught up with Konishi’s army at Mungyong, just north of Sangju, where the eastern and central routes to Hanseong merged. Kato was outraged that his rival, Konoshi, had disobeyed orders to wait for his arrival at Busan, and had instead advanced far ahead. Kato demanded that his forces now be allowed to take the lead and to capture Hanseong, but Konishi refused. The two armies crossed the Choryong Pass together and approached Chungju, where Kato suddenly announced that he would set up camp, hoping that Konishi would rush headlong into battle with Shin Rip’s cavalry, making him look foolish and incompetent.

The Battle

As with previous battles at Busan and Dongnae, Konishi split his army into two. Sō Yoshitoshi and Konishi took the left flank and centre with 15,000 men and the other commanders (Arima Harunobu, Ōmura Yoshiaki, and Gotō Mototsugu) with 3700 men took the right, fanning out into a large arc. Shin Rip lined up his cavalry division along the river. This classic Chinese strategy is known as bae-soo-jin (배수진, 背水陣 in Korean). However, as with previous engagements, the superior range and firepower of the arquebus-armed ashigaru soldiers inflicted heavy casualties on the crowded Korean forces while remaining out of range of the defender’s bows and spears. Shin Rip did manage one cavalry charge, but found that various vegetation on the plain impeded his horses and that the Japanese forces also employed a considerable number of pikemen, who were able to break his charge before he could penetrate the Japanese lines.

Shin Rip and a number of his commanders mounted on horses managed to escape the disaster; however, most of his men were cut down by the Japanese as they attempted to retreat. According to Japanese records, the Koreans lost 3000 men and several hundred were taken prisoner. As was customary, the heads of the slain were taken as trophies of war, but in this battle the number was too great, and it became the practice to take only the noses as “proof”, needed when the soldiers applied for rewards. The Japanese took Chungju with minimal losses. Shin Rip later killed himself to atone for the defeat by drowning himself in a spring a short distance from Chungju.

Aftermath and Legacy

After the battle, the forces of Kato Kiyomasa and Nabeshima Naoshige rejoined Konishi’s army. Kato was even further upset over Konishi’s success, and almost came to blows over who would lead the final attack on Hanseong. Konishi told Kato that there were two routes to the capital. The direct route to the northwest was the shortest, but crossed the Han River where the river was the widest. The other route was longer, to the north and then west, but crossed the Han River near its headwaters, where it was much narrower. He offered to draw lots over which route to take, but Kato demanded that he be given the direct route. Both generals set off the same night, not wishing for his rival to gain an advantage.

A messenger brought the news of the defeat at Chungju to King Seonjo on 07 June, causing widespread panic. Many fled the city with whatever possessions they could carry, including most of the guards. Although many officials urged King Seonjo to remain in the capital, Prime Minister Yi Sanhae overcame opposition by citing precedents for the king relocating in time of crisis. King Seonjo appointed General Gim Myeong-won as Commander-in-Chief and Field Marshal, and ordered him to defend the capital. Then the king moved to Pyongyang, since the Japanese began to seize the capital. He later moved even further north to the border city of Uiju just before the fall of Pyongyang. While the king was absent from the capital, many people who had lost hope in the government plundered the palace and burned many public buildings. This resulted in even more damage than that perpetrated by the Japanese after they had captured the city.

On 08 June, the vanguard of Kato’s army reached the Han River, finding that all boats on the south bank had been destroyed, either by the Koreans, or by Konishi’s men sent ahead to impede his progress. On the north bank of the river, Gim Myeong-won deployed his 50 officers and 1000 men to oppose Kato’s crossing. Undeterred by the lack of boats, Kato ordered his men to cut down trees and make rafts, effecting a crossing of the Han River near what is now the Yongsan District of Seoul on 11 June. Seeing that he was greatly outnumbered, and unnerved by the arquebuss fire from the Japanese troops, Gim fled his command disguised as a civilian, allowing Kato’s army to cross unopposed. He reached the South Gate of the city on 12 June, only to find that Konishi’s banner was already flying from its roof. Konishi’s forces had raced ahead of Kato, and had entered the city through its East Gate hours earlier. Four days later, on 16 June, the army of Kuroda Nagamasa reached the city, together with the army of 10,000 men led by Ukita Hideie of Bizen Province. The remaining five armies of Toyotomi Hideyoshi’s invasion force of 158,000 men had already arrived in the vicinity of Busan.
