義兵
On October 14, 5,000 rebels defended Mount Goseong Fortress against the Japanese. The rebels, using the fortress, fought fiercely against Colonel Suzuki's Japanese battalion, but were ultimately defeated by Japanese firepower. 187 rebels were killed, causing Mount Goseong to be called Mount Gosireong, after the sound that a decomposing corpse makes when it rains. The remnants of the rebels fled to Mount Jiri, where they became the Righteous Army.
