 The communists decided to take this advantage by concentrating three columns totaling eight divisions to attack Xifeng, Changtu, Kaiyuan, and annihilate the nationalist 53rd Army in the process.However, as communists were massing their troops on September 29, those regrouped at Xifeng were revealed by the nationalist aerial reconnaissance and the nationalist garrisons at Xifeng and adjacent regions immediately withdrew to safety, thus avoiding being surrounded by the enemy.communists then changed their strategy by ordering the 1st Column, 2nd Column, 6th Column, and 10th Column to be deployed to the regions to the north and south of Siping (city), and to Jiangmi Peak (Jiangmi Feng) located to the northeast of Jilin City, so that the nationalist Newly Organized 1st Army, the 60th Army and the 71st Army would be tied up.
