This research investigates the Korean, and the Taiwanese, Voluntary Armies. They were established in the context of the Sino-Japanese War. Their activities were underpinned by Chinese viewpoints on Korea and on Taiwan, in the middle of the twentieth century. This: research suggests that the politica1 function of the Armies was greater than their military function. In the beginning, they fought together against the Japanese army in Mainland China, for the emancipation of Korea and China. Later, when the Japanese army was gradually defeated, the Korean and the Taiwanese Voluntary Armies were both reorganised, and merged with other military units. As a result, their designations were no longer existent. Their achievements have been written down in history. The legend continued after the war. The former captain of the Korean Voluntary Armies, Ro-Shan Jin, returned to Korea, and became an acclaimed politician. But he was later denounced by South Korea, from which he eventually fled to North Korea, due to his socialistic belief and viewpoints on the issue of re-unification, after Korea had divided. Similarly, the former captain of the Taiwanese Voluntary Armies, Yo-Bang Lee, was arrested with respect to the Twenty-Eighth-Of-February Event in Taiwan, and executed in 1952, as a victim of the Nationalist government's white-terror, after China and Taiwan had divided. In the end, the legendary heroes of the war were no longer alive. The history of the Korean, and the Taiwanese, Voluntary Armies was distorted in the political conflict and ideological complex, in the middle of the twentieth century.
