On this day, 131 years ago, on July 23, 1894 (June 21, 1894 lunar calendar), the Japanese army occupied the Gyeongbokgung Palace of Korea. At dawn on July 23, 1894. In the dark, a group of Japanese troops tried to blast a door of the Gyeongbokgung Palace with explosives, but failed. So they climbed up and smashed it with axes, and with great effort smashed the door open, and the army swarmed in. Other doors were also opened, and the Japanese and Korean guards took control of the palace after a three-hour or so gun battle. By this time, the sky was bright. This kind of martial arts-like battle is not recorded in the official history of the Japanese army, and is only regarded as an occasional conflict. However, Professor Emeritus Akira Nakamura of Nara Women's University discovered detailed war history manuscripts in the Fukushima Prefectural Library, allowing the truth to be revealed a hundred years later.
