Nanking Garrison Force

Nanking Garrison Force. The Nanking Garrison Force was a temporary Imperial Japanese Army formation established in late 1937 for the specific purpose of occupying and securing the captured Chinese capital of Nanking. Primarily composed of units from the Shanghai Expeditionary Army, it was placed under the command of Prince Yasuhiko Asaka and played a central role in the Battle of Nanking and the subsequent occupation of the city. Its legacy is inextricably linked to the widespread war crimes and massacres perpetrated by Japanese troops during the infamous Nanking Massacre.

Background and formation

The force was created in the immediate aftermath of the Sino-Japanese War's pivotal Battle of Shanghai. Following the costly capture of Shanghai, the Imperial General Headquarters in Tokyo ordered the advance on the Chinese capital. As Japanese units from the Shanghai Expeditionary Army and the 10th Army converged on Nanking in early December 1937, the need for a dedicated command to control the captured metropolis became apparent. Prince Yasuhiko Asaka, an uncle of Emperor Hirohito, was appointed as its commander, arriving at the front and issuing critical operational orders. The formation was an ad-hoc assembly, drawing heavily from divisions like the 6th Division, 9th Division, 16th Division, and the 114th Division.

Organization and structure

The garrison force was not a standalone army but a designated command umbrella for the combat units tasked with securing Nanking. Its core consisted of frontline infantry divisions from the Central China Area Army, under the overall strategic command of General Iwane Matsui. Key constituent units included the 6th Division under Lieutenant General Kesago Nakajima, the 16th Division led by Lieutenant General Kensuke Okuyama, and elements of the 9th Division. While its exact strength fluctuated, it comprised approximately 7,000 to 10,000 troops directly involved in the initial occupation. The structure emphasized rapid mobility and overwhelming force for urban pacification, with logistical support tied to the broader Japanese Central China Area Army network.

Role in the Battle of Nanking

During the Battle of Nanking, the force executed the final assault and breach of the city's defenses. Following the collapse of the Chinese Nationalist army under General Tang Shengzhi, its units were the first to enter the city on December 13, 1937. Their immediate role shifted from conventional combat to disarming surrendering soldiers of the National Revolutionary Army and establishing military control over the urban center. The command, particularly under Prince Yasuhiko Asaka, is historically associated with the controversial "kill all captives" order that effectively removed legal restraints on troops, although the precise nature and transmission of this command remain debated among historians.

War crimes and atrocities

The garrison force is synonymous with the perpetration of the Nanking Massacre, a six-week period of extreme violence. Troops from its constituent divisions engaged in systematic massacres of prisoners of war and civilians, widespread rape, looting, and arson. Infamous incidents include the organized killings at the Mufu Mountain and along the banks of the Yangtze River. The atrocities were documented by international observers present in the Nanking Safety Zone, such as John Rabe and Minnie Vautrin, and were reported in newspapers like the New York Times. These actions constituted severe violations of the Hague Conventions of 1899 and 1907 and later formed a major part of the indictments at the International Military Tribunal for the Far East.

Post-war dissolution and legacy

The ad-hoc garrison command was dissolved after its immediate occupation duties concluded, with its units reabsorbed into the wider Japanese Central China Area Army for subsequent campaigns like the Battle of Wuhan. In the post-war period, its commander, Prince Yasuhiko Asaka, was granted immunity from prosecution by the Supreme Commander for the Allied Powers, Douglas MacArthur, due to his imperial status. Other officers, including General Iwane Matsui, were convicted of war crimes by the Tokyo Trials and executed. The legacy of the force is a central focus of historical and political discourse regarding Japanese war crimes, historical revisionism in Japan, and remains a profound point of contention in Sino-Japanese relations. Memorials such as the Memorial Hall of the Victims in Nanjing Massacre by Japanese Invaders ensure the events are remembered.
