10th Army (Japan)

10th Army (Japan). The 10th Army was a short-lived but significant formation of the Imperial Japanese Army during the Second Sino-Japanese War. Activated in late 1937, it played a central role in the final stages of the Battle of Shanghai and the subsequent Battle of Nanking. The army was primarily composed of reserve divisions and was disbanded in early 1938 after the conclusion of its major offensive operations.

History

The 10th Army was formed on 13 October 1937 under the Imperial General Headquarters to reinforce Japanese forces engaged in the protracted and costly Battle of Shanghai. Its creation was part of a major escalation following the Marco Polo Bridge Incident, intended to deliver a decisive blow against the National Revolutionary Army. After landing north of Shanghai at Hangzhou Bay in early November, the army's rapid advance helped outflank Chinese defenses, leading to the fall of Shanghai and a subsequent drive toward the Chinese capital. Following the capture of Nanking and the ensuing Nanking Massacre, the army's strategic purpose was largely fulfilled, leading to its dissolution on 15 February 1938, with its components reassigned to the Central China Area Army and other commands.

Organization

Upon its activation, the 10th Army was a formidable force built around several core divisions, notably the 6th Division, the 18th Division, and the 114th Division. It also included the Kunizaki Detachment from the 5th Division and was supported by substantial artillery and logistical units. The army was later reinforced by the 16th Division during the advance on Nanking. This organizational structure, blending veteran and reserve formations, was typical of Japanese expeditionary forces deployed to the China theater.

Commanders

The sole commanding officer of the 10th Army was General Heisuke Yanagawa, a veteran commander who had previously served as Vice-Minister of War. His chief of staff was Major General Rensuke Isogai, who later became Governor-General of Hong Kong during its occupation. The army's operations were conducted under the overall strategic direction of the Central China Area Army, commanded by General Iwane Matsui, who was later convicted for his responsibility in the Nanking Massacre by the International Military Tribunal for the Far East.

Operations

The 10th Army's primary operation was its landing at Jinshanwei on Hangzhou Bay on 5 November 1937, a maneuver that successfully broke the stalemate at Shanghai. It then spearheaded the western advance, capturing Suzhou and contributing to the chaotic retreat of Chinese forces toward Nanking. The army's units, particularly the 6th Division and the 16th Division, were heavily involved in the fierce fighting during the Battle of Nanking in December 1937. Following the city's capture, elements of the army participated in the subsequent punitive campaigns in the surrounding regions of Jiangsu and Anhui before its disbandment.
