Пэн Дэхуай
After Panlong Campaign, the communist force under the command of Peng Dehuai in northwest China had scored three consecutive victories against its nationalist adversary, and had forced the nationalists in northwestern China to cease further offensives. Both sides took rest and the communists held a celebration at Ansai () region during this break. Zhou Enlai personally went to join the celebration on Mao Zedong's behalf and suggested that Peng's force should take the opportunity to take a much-needed break while the nationalists were resting, but Peng Dehuai disagreed because Ansai region was a very poor region lacked any resources and thus could not support his large army numbered over twenty thousands. Instead, Peng Dehuai suggested that his force should strike toward eastern Gansu while the local nationalist force under the command Hu Zongnan was resting, so that the communists could replenish themselves in the newly conquered area in eastern Gansu. When Peng's suggestion was finally telegraphed to Mao Zedong on May 14, 1947, Mao replied in the same day and agreed. Peng Dehuai also hoped that taking eastern Gansu would force the Ma clique to redeploy its forces and thus provide an opportunity for another communist victory, as he and Xi Zhongxun had told Mao in their telegraph on May 28. Little did the communists know how wrong they were.
