The 'Battle of Tadaejin', along with the
Siege of Busan, was one of the first battles of the
Imjin War (1592-1597). The
Battle of Busan and the Battle of Tadaejin occurred almost simultaneously. Tadaejin is also transliterated as "Dadaejin".
The Battle of Tadaejin
The Japanese quickly landed at the harbor and advanced upon the fortress. The battle pitted the Korean commander
Yun Heung-sin (
Hangul: 윤흥신
Hanja :尹興信) against
Konishi Yukinaga, the first commander of the
First Division of the Japanese army. Yun's brother
Yun Heung-Jae (
Hangul: 윤흥제
Hanja :尹興梯) was also at the battle. The Korean commander quickly led his troops onto the walls for a defense, while Konishi landed in the harbor and charged, using the same tactic as So Yoshitoshi of draining the moat under cover of arquebuse fire. The arquebuses caught the Korean garrison at Tadaejin off guard. Similar to Busan, the Korean soldiers were terrified at the arquebuses and were incapable of effectively countering them.
The Koreans were unable to prevent the Japanese from draining the moat and thus having direct access to the defensive walls. The Japanese used siege towers, ladders, and the cover of arquebuses to scale the defense against a barrage of arrows and rocks launched by the Koreans.
Yun waited for the first line of defense to be breached, feined a retreat, and mounted a massive counter-attack and caught the Japanese by surprise. After fierce
mêlée fighting, the main walls were breached and the city was taken. Like Busan, Tadaejin was looted, pillaged, and burned, with most of its civilian population massacred.
Conclusion
Konishi secured Tadaejin for reinforcements' landings. He immediately regrouped his army and marched towards Seoul, the Japanese army's main objective. Konishi and So Yoshitoshi, the attacker at Busan, met little resistance on their advancement (see
Battle of Chungju and
Battle of Sangju). The failure to defend
Choryang Pass, a strategic defensive post, forced the Koreans to retreat and the Japanese armies reached the outskirts of Seoul in less than a month.
