The Battle of South Shanxi, also known as the Battle of Jinnan and Zhongtiao Mountains campaign by the Chinese and as the Chungyuan Operation by the Japanese, was one of the 22 major engagements between the National Revolutionary Army and the Imperial Japanese Army during the Second Sino-Japanese War (1937 - 1945).
The disastrous losses of the first year of the war (1937-38) meant that the internationally-recognized Chinese government (controlled by the Kuomintang or KMT party) had been forced to abandon its capital and all the industrialized areas of the country. It fought on from a new base in the west, mainly the province of Sichuan and Guanzhong.
The Zhongtiao Mountains held symbolic importance as the largest area of territory north of the Yellow River still under full Chinese control.
They also had some strategic importance as defensive ground on the north bank of the Yellow River. Beyond the south bank lay the railway line connecting the KMT's western base with the Zhongyuan central plain, the 'breadbasket of China'.[2]
The area of the battle was very roughly in the shape of a triangle, with the Yellow River as the base to the south. On the northwest side were Japanese armies that had advanced down the railway line from the north as far as its Yellow River terminus at Fenglingdu. Likewise, the frontline to the northeast side was the territory captured by the Beiping–Hankou Railway Operation.
At the onset of the battle, KMT-CPC relations were at a low point following the still recent New Fourth Army incident in early 1941. As a result, the nearby 8th Route Army refused to assist the surrounded Nationalists. South Shanxi was later remembered in China as one of the worst defeats of the entire war.
The campaign is extensively discussed in the travel book Two Kinds of Time by the US journalist Graham Peck, based on eyewitness interviews with refugees. Peck reports that the NRA had built a line of fortifications overlooking the major roads through the mountains, which had withstood several earlier Japanese assaults. It was garrisoned by second-line warlord troops. He claims that the Chinese commanders had become complacement and were caught out when the Japanese adopted new, guerrilla-style tactics. They used peasant paths to infiltrate into the mountains and encircled the mountain range by moving along north bank of the Yellow River. Once they realized they were surrounded, the Chinese forces disintegrated before better-quality troops could be brought across the river.[3]
