The Battle of Jinan was a critical engagement fought between the Kuomintang and the Communist Party of China from September 16 to September 24, 1948 during the Chinese Civil War. The communist Eastern ChinaField Army besieged and finally captured the city of Jinan, the capital of Shandong Province and a major urban center as well as a transportation hub in northeastern China that had a population of about 600,000 at the time of the battle. The communist victory set the stage for the Huaihai Campaign. The defenders of Jinan had become isolated in the summer of 1948, when the communist Eastern China Field Army commanded by Chen Yi captured the railway line south of the city. In charge of the city's defense was general Wang Yaowu, he commanded nine regular brigades, five security brigades, as well as special force units amounting to a total troop strength of about 100,000. The defenses of Jinan were organized into two lines: an outer ring around the outskirts of the city and inner line following the historical city wall. The outer ring was fortified by a four-ply line of pillboxes, barbed wire, and a newly dug 3-meter wide moat. The inner ring consisted of the ancient brick wall of the city that had been strengthened with sand bags. The most valuable strategic assets of the city, the main airfield, the railroad station, and the commercial district, were located to the west of the historical city center and outside of the inner ring. Hence, they were protected only by the outer ring of defenses. The communist forces encircled the city in a pincer movement carried out by an eastern and a western group. The eastern group was composed of the 9th column, the Bohai column, and one division of the Bohai military region. The western group consistent of the 3rd column, the 10th column, the Liang Guang column, four regiments of the mid-south Shandong column, and one division from the Jiluyu Military Region. The 13th column served as the preparation team for the entire attack. General Wu Huawen was in charge of the outer ring of defenses. General Wu defected to the communist side with about 8,000 of his troops before the battle began. His defection may have been prompted by letter sent to him by close relatives who had been captured by the Communists in the summer. Most of Wu's troops had fought on the Japanese side during the Second Sino-Japanese War and were integrated into Su Yu's forces immediately. After the outer ring of defenses was lost due to Wu's defection, communist forces launched a bloody assault on the historical city center. The historical city wall was first breached at its southeastern corner around 2am on September 24. Another breach at the southwest corner also occurred before dawn. After the city wall was breached, the remaining Kuomintang garrison was quickly overrun and captured. General Wang Yaowu tried to escape in civilian clothes but was captured in Shouguang County. Pang Jingtang, the Kuomintang party chief in Shandong as well as 23 other high-ranking Kuomintang officials were also captured. Jinan was the first major urban center to be captured by the communists. Zhou Enlai hence referred to the Battle of Jinan as the starting point for the "three great battles", namely the Liaoshen Campaign, the Huaihai Campaign, and the Pingjin Campaign that established communist control over northern China.
