Meanwhile, two nationalist brigades of the nationalist 8th Army in Shandong were transported to Qinghuangdao by sea and then pushed toward to the region west of Luan (滦) county in an attempt to besiege the enemy, but the enemy was already withdrawn to Lulong (卢龙) and Qian'an (迁安) regions, thus successfully avoided the nationalist trap. Taking the advantage of the failed nationalist attempt to trap the enemy, the communist Right Flank Corps struck northward, taking Stone Box (Shixia, 石匣), Little Battalion (Xiao Ying, 小营) and besieged Ancient North Gate (Gu Bei Kou, 古北口) on June 19, 1948, thus forcing the nationalists to withdraw their troops elsewhere and redeploy them to reinforce the northern front. Taking the advantage of the nationalist redeployment, the communist 11th Column and the communist Left Flank Corps launched another offensive on June 23, 1948, and by June 25, 1948, successfully took all of the nationalist strongholds along the Stone Gate Street (Shi Men Jie, 石门街) to Lichang (昌黎) City line, thus concluding the campaign by severing the important link between northern China and Northeast China on land.
