Battle of Jiksan

The Battle of Jiksan (직산 전투) was a military conflict fought between Ming and Japanese forces on 16 October 1597. It resulted in withdrawal by both sides. However the battle marked the furthest point the Japanese ever got to reaching Hanseong during the Second Invasion.

Background
Ma Gui led Niu Boying and Jie Sheng to Jiksan, modern Cheonan, and laid an ambush there for the Japanese army.

Battle
On 16 October 1597, Kuroda Nagamasa's force of 5,000 arrived at Jiksan, where 6,000 Ming soldiers were stationed. Kuroda's forces charged the enemies and was soon joined by the rest of the army, bringing Japanese forces to 30,000. Although heavily outnumbering the Ming, the Japanese were unable to do much damage due to the Ming's superior armor. According to Kuroda and Mōri Hidemoto, their firearms could not penetrate the iron shields used by Chinese soldiers, and their armor was at least partially bulletproof. The battle continued until dusk when the two sides withdrew. It is disputed as to whether the Ming or Japanese army withdrew first, and consequently which side won the battle.

Kuroda launched another attack at night, this time in a pronged sweeping crane formation that sought to crush the enemies between them. The attack failed and turned into a rout that was joined by 2,000 Ming cavalry.

Aftermath and implication
Jiksan was the furthest the Japanese ever got towards reaching Hanseong (Seoul) during the second invasion. Although they were forced to withdraw at Jiksan, it was not a major loss, and resulted in an orderly retreat south by the Japanese.
