Zhang Guotao
In 1931, the Chinese Red Army defeated the Nationalist forces three times with a large-scale attack, causing the Nationalist forces to lose nearly 100,000 soldiers. Several smaller red armies came together and formed a group army. In the summer of 1931, General Zhang Guotao arrived at the Fourth Red Army's base area and took over the army. Most of the Fourth Red Army's senior officers were killed by him, including Xu Jishen, Zhou Weijiong, and Xiaofang. Similar movements also occurred in western Hubei Province; in the spring of 1931, Xia Xi took over He Long's army and killed most of his senior officers including Duan Dechang.
