Jo Heon (Korean: 조헌; Hanja: 趙憲, 1544 – 1592) was a Joseon official and militia leader[1][2] in Korea at the time of the Imjin war.
In August, he received a message from Ko Kyŏng-myŏng, another civilian militia leader, who proposed that they join forces and recapture Seoul.
Cho agreed to this plan and prepared to leave his current position Chungchong province to attack Seoul.
However, Ko backed out when he found the Japanese intended to invade his home province; instead he attacked Geumsan during which he was killed.
They defeated a small Japanese advance party, and approached the walls, but withdrew due to intense rain.
[9] In the aftermath of the battle, the provincial governor Yun Son-gak filed an official report that did not credit Cho Hon's militia.
Cho, resentful after his treatment in Yun Son-gak's report, announced that his militia would attack Geumsan alone, before any other Korean force did.
