淮海战役
On November 29, 1948, the Chinese Communists' People's Liberation Army (PLA), fresh off a decisive victory in Manchuria, launched the Pingjin Campaign. They captured Zhangjiakou to the northwest on December 24 and Tianjin to the southeast on January 15, 1949. With the defeat of the Nationalists in the Huaihai Campaign further south, Fu Zuoyi and over 200,000 Nationalist defenders were surrounded in Beiping. After weeks of intensive negotiations, Fu agreed on January 22, 1949, to pull his troops out of the city for "reorganization by the PLA." His defection spared the city, its residents and its historical architecture from imminent destruction. On February 3, the PLA marched into Beiping.
