103rd Division

The 103rd Division (1st Formation) was an infantry division of the Chinese People's Liberation Army during the final phase of the Chinese Civil War and the early consolidation of the People's Republic of China. It was created in October 1948 from the reorganized 155th Brigade of the 96th Reorganized Corps of the Republic of China Army after that formation defected to the People's Liberation Army. The new division was assigned to the PLA's 35th Corps. The division was reorganized and expanded during the following months. In February 1949, it absorbed the 47th Division of the Luzhongnan Column of the PLA. This restructuring produced the division's three principal regiments: the 308th Regiment was formed through the merger of three regiments from the original 161st Reorganized Brigade, while the 307th and 309th Regiments were reorganized from the 139th and 140th Regiments of the former 47th Division. The changes reflected the PLA's broader wartime effort to consolidate forces and standardize divisional structures as it advanced toward the Yangtze River. In April 1949, the 103rd Division participated in the Nanjing Campaign, one of the decisive operations of the Chinese Civil War. The campaign resulted in the capture of Nanjing, then the capital of the Republic of China government on the mainland, and marked a major political and military turning point. The division's available historical record identifies its participation but does not provide a detailed account of its individual operations, casualties, commanders, or battle honors. Beginning on January 16, 1950, the division was used in the role of the Taizhou Military Sub-district. This change came during the PLA's postwar transition from large-scale mobile formations toward territorial administration, local security, demobilization, and the establishment of military-subdistrict institutions. The 103rd Division was ultimately disbanded on February 15, 1951. At the time of disbandment, its documented order of battle consisted of the 307th, 308th, and 309th Regiments. The designation is specific to the first formation of the People's Republic of China's 103rd Division and should not be confused with other military units that have used the number 103 in different countries, services, or historical periods. The surviving reference material does not establish a continuing successor organization, commercial identity, independent website, or publicly listed corporate structure.

The 103rd Division was formed in October 1948 during the final campaigns of the Chinese Civil War. Its initial nucleus came from the reorganized 155th Brigade of the 96th Reorganized Corps of the Republic of China Army, which had defected to the Chinese People's Liberation Army. After its creation, the division became part of the PLA's 35th Corps. The division underwent a major restructuring in February 1949 when it absorbed the 47th Division of the Luzhongnan Column of the PLA. The reorganization established the three-regiment structure documented for the division's later existence. Three regiments from the former 161st Reorganized Brigade were combined to form the 308th Regiment. The 307th and 309th Regiments were reorganized from the 139th and 140th Regiments of the absorbed 47th Division, respectively. The 103rd Division participated in the Nanjing Campaign in April 1949. The operation was part of the PLA's advance across the Yangtze River and led to the capture of Nanjing, a central political and military objective of the campaign. Available reference material confirms the division's participation but does not preserve a detailed account of its tactical assignments, commanders, losses, or specific engagements within the campaign. After the establishment of the People's Republic of China, the division's role shifted from wartime field operations toward territorial administration. Beginning January 16, 1950, it acted as the Taizhou Military Sub-district. This administrative role was part of the broader transition in which PLA formations were reorganized to support local defense, public security, political consolidation, and regional military administration. The division was disbanded on February 15, 1951. Its recorded final composition was the 307th Regiment, 308th Regiment, and 309th Regiment. The available sources do not identify a successor unit or indicate that the 103rd Division continued under another designation. Because the name is shared by other military formations, this entry refers specifically to the first 103rd Division associated with the People's Republic of China.
