1st Group Army (Collaborationist) was a major military formation of the Collaborationist Chinese Army loyal to the Wang Jingwei regime during the Second Sino-Japanese War. Established in 1943 through the reorganization of existing puppet forces, it operated under the overarching command of the Imperial Japanese Army in North China. The unit was primarily tasked with garrison duty and anti-partisan operations against the Eighth Route Army and other Chinese resistance groups, playing a significant role in the Japanese pacification campaigns.

Formation and organization

The 1st Group Army was formally organized in 1943 as part of a broader restructuring of the Wang Jingwei government's military apparatus. This consolidation aimed to improve the effectiveness of collaborationist troops by merging several independent peace preservation corps and former National Revolutionary Army units that had defected following the Battle of Wuhan and other Japanese military advances. The formation was directly supervised by Japanese military advisors from the North China Area Army and was structured to function as a corps-sized auxiliary force.

Operational history

Deployed primarily in the Hebei and Shandong provinces, the 1st Group Army's operational history was defined by its involvement in the protracted counter-insurgency against Chinese Communist Party guerrillas. It participated in numerous mop-up operations, such as those in the Taihang Mountains and along the Yellow River, often in direct support of Japanese Kwantung Army units. Its engagements were characterized by scorched earth tactics and the defense of strategic railway lines like the Tianjin–Pukou Railway and Beijing–Hankou Railway against sabotage.

Command structure and leadership

The army was commanded by the notorious former Nationalist general Sun Dianying, whose forces had previously been active in the Central Plains War and the Defense of the Great Wall. Sun's authority was circumscribed by a detailed chain of command that ultimately answered to the Japanese Central China Expeditionary Army headquarters in Nanjing. Key staff positions and logistical support were controlled by Japanese liaison officers, ensuring the collaborationist force remained subordinate to Imperial General Headquarters directives.

Composition and units

The 1st Group Army comprised several divisions and independent brigades, many of which were former regional militia or warlord contingents. Core subordinate formations included units like the 24th Army (Collaborationist) and the Temporary 1st Corps, though their designations and strength fluctuated significantly. The army was notoriously under-equipped, relying on captured Kuomintang materiel and limited supplies of Arisaka rifles and Type 92 battalion guns provided by the Japanese arsenal.

Role in the Second Sino-Japanese War

Within the broader context of the Second Sino-Japanese War, the 1st Group Army served as a force multiplier for Japan, freeing up regular Imperial Japanese Army units for front-line combat against the National Revolutionary Army and United States Army. Its role was integral to the Japanese strategy of "using Chinese to control Chinese," particularly in securing the occupied hinterland from the Communist base areas like the Shanxi–Chahar–Hebei border region. Its actions contributed to the severe hardships faced by civilians during the Three Alls Policy.

Disbandment and legacy

Following the Surrender of Japan and the dissolution of the Wang Jingwei regime in August 1945, the 1st Group Army was swiftly disbanded. Many of its rank-and-file soldiers were absorbed into the National Revolutionary Army during the immediate post-war period, while its senior officers, including Sun Dianying, faced charges of treason and collaborationism. The army's legacy is a contentious subject in historiography of the Second Sino-Japanese War, emblematic of the complex moral ambiguity and brutality that characterized much of the collaboration with the Axis powers in China.
