Portuguese missionary's record of the Imjin War against Busan.

 "Gonishi, along with 20,000 combatants, boarded 643 large and small ships in the village and departed Tsushima Island. In particular, the fortress called Busanseong Fortress was the first gateway for the Japanese to come in, so there were about 600 soldiers there, and in addition, there were commoners collected from the village. In the year, all irons with pointed ends were sprayed in front of the camp to prevent enemy invasion, and 2,000 small guns made of copper were placed inside the fortress. Some of them were capable of firing small gunshots, and others were capable of firing two-spread arrowheads. All of the Korai soldiers were armed with a chest made of very solid leather, and they were wearing iron helmets to block arrows on their heads, and among them were archers and soldiers who also used sloping spears. Finally, on April 12 of the lunar calendar, Konishi ordered all villages outside the fortress to be called first. Then, he went to the front of the fortress captain and sent a letter stating that he would recommend surrender and save his life. Upon receiving this letter, the captain laughed at it and replied, "If I give permission, I will surrender." As great warriors, the Korai soldiers were filled with loyalty to the king and fought bravely to the last man. The garrison took the lead and was killed for the first time, and no one survived. Family Korai women were famous for their cleanliness and moderation. On the other hand, the male and female children of the nobleman's family are straight-looking and educated, and they disguised themselves as pigeons by twisting their legs or mouths. However, the Japanese army recognized the fact and were not afraid to save them as prisoners." At that time, the battle was from Myosi (5-7:00) to Sashi (10-12:00), and the Japanese army killed all men, women, dogs, and cats after occupying Busanjinseong Fortress.
