Siege of Namwon The Siege of Namwon was a battle of the Imjin War ( 1592 - 1598 ) . The samurai armies of Japan had invaded the Korean peninsula , and in the summer of 1597 laid siege to the city of Namwon , which was defended by a combined garrison of Korean and Ming Chinese troops . The defenders faced overwhelming odds , and after fierce fighting , the Chinese general entered into secret negotiations with the Japanese commander . In exchange for safe passage for him and his men , they would leave one gate open and undefended . Both sides honored the bargain . The Chinese were allowed to withdraw and the Japanese forces poured into the city . The Koreans fought hard , but were reportedly all killed , with the exception of one survivor . History . A Japanese Force of 56 , 000 soldiers led by Ukita Hideie besieged and assaulted Namwon , defended by 10 , 000 Korean and Chinese Soldiers and at least 5 , 000 women and children . The city was protected by a wall , constructed in the northern Chinese style , with a shallow dry moat , and corner gun towers . The Koreans wanted to relocate to the nearby mountain fortress because of their knowledge of the terrain . This also would have given them the higher ground . However the Chinese general Yang Yuan demanded the defense of the city claiming that he had fought and won numerous battles in China therefore he knew what strategy would serve them best . He wanted to withstand the siege from within the city walls . He felt more comfortable defending the Chinese style city wall than a Korean style hill top fortress . As the city was on flat ground , with high ground all around it , the city was immediately placed under arquebus fire from day one , from all sides . General Yi Bok Nam and his cavalry was able to successfully repel the Japanese attack several times . However , with the annual rainfall the flat land was reduced to fields of mud rendering the Korean horsemen and their steeds useless . As morale plummeted and casualties mounted , the Chinese general Yang Yuan who was defending the South wall with his troops negotiated with the Japanese in a secret meeting . In exchange for a safe retreat for himself and his troops Yang Yuan would give up the south wall and entrance to the Japanese without aggression . When Yang Yuan left abandoning the south wall the Japanese entered through the gates , Yi Bok - nam rode out along with his soldiers and met the Japanese . Every Korean defending Namwon fought to their death . None survived except for one 12 - year - old boy who carried the royal seal of the Korean Emperor . He was taken back to Japan where he was adopted and raised within a Japanese household . Order of battle . Defense . Ming - Chinese forces 3 , 000 men .
