The East China Military Region, the East China Field Army and the Jiaoji Road Field Army in "The Biography of Zhang Yunyi" were formed

Participated in the formation of the East China Military Region and the East China Field Army, and the troops in East China were reorganized, and as early as after the fall of Huaiyin, the Shandong Field Army and the Central China Field Army prepared to concentrate on actions towards Huaibei. The CPC Central Committee also gave instructions, proposing Chen Yi as commander and political commissar. However, due to the changing tide of the war, this plan was not immediately realized. However, after the Battle of Subei, the party, government, and military organs in central China went north to Shandong, and Chen Yi and others began to reconsider the issue.

On December 23, 1946, Chen Yi and others jointly sent a telegram to the CPC Central Committee and the East China Bureau, suggesting that the Central China Branch be merged with the East China Bureau, the Central China Military Region and the Shandong Military Region, and Huaye and the Mountain Field, so as to realize the unified leadership and unified revenue and expenditure of Central China and Shandong. The CPC Central Committee replied on December 25 and instructed that one or two responsible persons of the Central China Bureau must remain in Central China. Subsequently, the merger of the leading organs was officially launched.

In a telegram dated January 16, 1947, Chen Yi, Tan Zhenlin, and Chen Shiyu made proposals to the Central Military Commission and Liu Bocheng and Deng Xiaoping to discuss the replenishment, reorganization, and next steps of the East China Army. After the assembly, Rao Shushi, Zhang Yunyi, and others returned to Linyi to deploy the merger of local organs, while Chen Yi and others were responsible for the reorganization of the field army.

From January 21, 1947, the New Fourth Army merged with the Shandong Military Region, Central China Military Region, Shandong Field Army and Central China Field Army to form the East China Military Region and the East China Field Army. The leading organ of the East China Military Region is based on the former New Fourth Army and the leading organ of the Shandong Military Region, plus a part of the headquarters of the Shandong Field Army. The headquarters of the East China Field Army is composed of the former Central China Field Army Headquarters and the Central China Military Region Headquarters, plus a part of the Shandong Field Army Command. The commander of the East China Military Region is Chen Yi, and the political commissar is Rao Shushi. The commander of the East China Field Army was Chen Yi, the deputy commander was Su Yu, and the deputy political commissar was Tan Zhenlin.

The East China Military Region has jurisdiction over the Lunan, Luzhong, Jiaodong, Bohai, Jiangsu Central and Northern Jiangsu Military Regions, with a total of about 300,000 people. The East China Field Army has 9 infantry columns and 1 special forces column, with a total of 270,000 people. In order to improve the operational situation on the Jiaoji Line, the East China Field Army planned to set up a command post on the Jiaoji front line and command the 8th, 9th, and 10th Columns to fight on the Jiaoji Line.

In the process of reorganization, the replenishment of the troops of the columns, especially the formation of the 8th, 9th, and 10th columns and special forces columns, was not fully completed until after the Battle of Laiwu. The Central China Bureau was merged into the East China Bureau, and the new East China Bureau Standing Committee included Rao Shushi, Chen Yi, Zhang Yunyi, Li Yu, Shu Tong, Deng Zihui, Tan Zhanlin, Su Yu, Zhang Dingcheng, and Liu Xiao. The secretary of the East China Bureau is Rao Shushi, and the deputy secretaries are Chen Yi and Li Yu.

After the reorganization, both the East China Military Region and the East China Field Army ushered in a new stage. The military districts and columns under their command will operate on the Jiaoji Line and Longhai Road fronts to support the Liberation War. The implementation of the reorganization plan brought the military struggle in East China to a new stage.

Participated in the formation of the East China Military Region and the East China Field Army

The reorganization of troops in East China was carried out under the instructions of the CPC Central Committee and the Central Military Commission. As early as after the fall of Huaiyin, when the Shandong Field Army and the Central China Field Army were preparing to concentrate on Huaibei, on September 23, 1946, the CPC Central Committee sent a telegram to Chen Yi, Zhang Dingcheng, Deng Zihui, and Tan Zhenlin: "The two armies of Shanye and Huaye should act in a concentrated manner, and the two headquarters should also be united. Chen Yi was proposed as commander and political commissar. Su Yu was the deputy commander and Tan Zhenlin was the deputy political commissar. If agreed, it will be announced (internally) for implementation. Who is the appropriate person for the chief and deputy chiefs of staff. Telegrams at your discretion. "Due to the evolution of the war situation, the desire to merge the Shandong Field Army and the Central China Field Army into one was not immediately realized. However, after the Battle of Subei, as the party, government, and military organs in central China moved north to Shandong, Chen Yi and others began to reconsider this issue. On December 23, 1946, Chen Yi, Zhang Dingcheng, Deng Zihui, Su Yu, and Tan Zhenlin jointly sent a telegram to the CPC Central Committee and the East China Bureau: It was suggested that the Central China Branch and the East China Bureau, the Central China Military Region and the Shandong Military Region, and Huaye and Shanye be merged, so that Central China and Shandong would be unified in leadership and unified revenue and expenditure. On the 25th, the CPC Central Committee replied and agreed, and instructed that "one or two responsible persons of the Central China Branch must stay in Central China (leading organs with light rates)." Subsequently, the merger of the leading organs was officially launched. On December 24, Rao Shushi also set off from Yan'an to return south to Shandong. On January 16, 1947, Chen Yi, Tan Zhenlin, and Chen Shiyu sent a telegram to the Central Military Commission and Liu Bocheng and Deng Xiaoping: "Zhang Li and Zhang Deng are discussing the replenishment, reorganization, and operation of the East China troops in Shandong. Rao arrived in Tai'an yesterday, and within a few days he can go to Linyi and come to the front. On 23 July, Chen Yi, Su Yu, and Chen Shiyu sent a telegram to the Central Military Commission and Liu Bocheng and Deng Xiaoping: "After we gathered for discussion, Comrade Rao Zhangzhu returned to Linyi yesterday to deploy the merger of local organs, and we deployed integrated troops on the front line and prepared to rest for two weeks to fight the European Earthquake Department." These two telegrams clearly showed that while the Lunan Campaign was still in progress, Zhang Yunyi and Li Yu, Zhang Dingcheng, and Deng Zihuan began to discuss the replenishment, reorganization, and next steps of the Shandong Field Army and the Central China Field Army. After the end of the Battle of Lunan, Zhang Yunyi, Li Yu, and others arrived at Qianhai Camp and held a meeting with Chen Yi and others to discuss and study issues such as the merger of the field army and the military region. The New Fourth Army merged together with the Shandong Military Region, the Central China Military Region, the Shandong Field Army and the Central China Field Army to form the East China Military Region and the East China Field Army, and established the command organs and departments of the East China Military Region and the East China Field Army.

The East China Military Region has jurisdiction over the Lunan, Luzhong, Jiaodong, Bohai, Jiangsu, and Northern Jiangsu Military Regions, the East China Military and Political University, the Dongjiang Column, the Huaibei Detachment, and the Binhai Naval Subdistrict, totaling about 300,000 people. The East China Field Army had 9 infantry columns and 1 special forces column under its jurisdiction. The leading organs of the East China Military Region are composed of the former New Fourth Army and the leading organ of the Shandong Military Region plus a part of the headquarters of the Shandong Field Army, and the headquarters of the East China Field Army is composed of the former Central China Field Army Headquarters and the Central China Military Region Headquarters plus a part of the Shandong Field Army Command.

After the reorganization of the troops of the East China Military Region, they faced two operational directions: Longhai and Jiaoji. In order to improve the operational situation on the Jiaoji Line, the East China Field Army set up a command post on the Jiaoji front to command the 8th, 9th, and 10th Columns to fight on the Jiaoji Line. The East China Military Region commanded other columns to fight on the Longhai Road front.

After the completion of the reorganization, the East China Military Region and the East China Field Army became the leading organs and main forces of the military struggle in East China, and played an important role in the victory of the Liberation War.
