Meanwhile, on the northern bank of Great Clearity River (Da Qin He 大清河) in Shengfang (胜芳) region, the Independent 7th Brigade of communist Central Hebei Military District and local garrison of the communist 10th Military Sub-district successfully beat back repeated attacks of the nationalist reinforcement. However, the communist victory was largely due to the lack of cooperation among nationalists themselves: out of a total of seven divisions, only 13 regiments actually participated in the assaults on the communist positions, less than half of the total. The reason was that Yan Xishan, the nationalist commander-in-chief and the warlord of Shanxi, was not willing to sacrifice his own troops for Chiang Kai-shek and other warlords allied with Chiang, which resulted in further disasters for the nationalists: after beating back the nationalist attacks, the Independent 7th Brigade of communist Central Hebei Military Sub-region and local garrison of the communist 10th Military Sub-district further expanded their victories by taken nationalist strongholds including Tang'erli (堂二里) township of Ba (霸) County, Anci (安次) county, and the region of Xushengkou (徐胜口) on 27 April 1947.
