27 Brigade (二七部隊) was a guerrilla force formed in Taichung, Taiwan, shortly after the outbreak of 228 Incident. It was organized by Hsieh Hsueh-hung, a leading figure of Taiwanese Communist Party during the Japanese Administration Era, and was led by local Taichung scholar Chung Yi-ren. The total strength of the brigade remains disputed, with sources putting it as low as 30 and as many as 4,000; however, it is agreed that the bulk of the force was made up of young students and discharged soldiers who had fought in World War II for the Empire of Japan. One source also claims that the 27 Brigade discovered a secret weapon cache left by the Japanese that contained enough weapons and ammunition to arm "three whole divisions," which remains disputed today.
