In coordination with the guerrilla forces in the southeast, the Chinese repeatedly struck at the Japanese forces that had penetrated to I-chang. As a result, the Chinese believed that the Japanese forces at I-chang and Sha-shih found their flanks exposed and in a difficult position. To relieve themselves of this threat they launched an offensive against the Chinese forces in late November. Japanese sources say the purpose was to probe to find the location of the Army of Tang Enbo. If that was their purpose they were to be disappointed.
