After the fall of Hsinchu, however, locally recruited Formosan troops began to take the lead in the fighting against the Japanese. In particular, Hakka militia units led by the youthful commanders Chiang Shao-tsu (姜紹祖), Wu Tang-hsing (吳湯興) and Hsu Hsiang (徐驤) put up a stubborn resistance to the Japanese advance. Between 24 and 26 June the Japanese had to turn back to An-ping-chin and fight a major engagement to capture the heights of Shih-pa-chien-shan (Traditional Chinese: 十八尖山). The Japanese, with superior training and better weapons, eventually succeeded in throwing the Formosans off the mountain. But although defeated, the Formosans remained for several days in the vicinity of Hsinchu, demonstrating on more than one occasion against the city.
