Battle of Kunlun Pass - The Battle

The Battle

The Imperial Japanese army launched a major offensive into Guangxi province. With the objective to cut off the Chinese supply route from French-controlled Vietnam, the elite Japanese 5th Division spearheaded the Japanese offensive. After occupying Nanning in November 1939, the Japanese captured the key point of Kunlun pass and threatened the Chinese rear base that protected Chungking, the wartime capital.

Realizing the danger of being isolated from the outside world and impossible to receive more aid if the Japanese troops were not repulsed, General Bai Chongxi—himself a native of Guangxi—asked the Nationalist Government for reinforcements. Chiang Kai-shek in turn dispatched the 5th Corps from Hunan province to fight the Japanese.

The 5th Corps was the most elite unit in the NRA, and it is also the only Chinese unit that had tanks and armored vehicles. Its soldiers were combat-hardened veterans from previous battles against the Japanese troops, and its soldiers' morale was high as a result. General Du Yuming, commander of the 5th Corps, dispatched two divisions to attack the Japanese-held Kunlun Pass. The new 22nd Division had cut off Japanese reinforcement from the rear and killed the Japanese commander, Major General Masao Nakamura.

The most elite unit of the Japanese 5th Division—the 21st Brigade—was wiped out in the battle. The Brigade had also participated in the Russo-Japanese War, and it was nicknamed the "unbreakable sword". Before Major General Nakamura's death, he admitted in his diary that the Chinese soldiers' fighting ability had surpassed the Russians whom the Brigade encountered in Manchuria. This campaign was the first major victory of the Chinese army since the Fall of Wuhan.
