Battle of Shanggao

• 1. Introduction

  ›

  The Battle of Shanggao began on the 14th of March 1941, when the Japanese 11th Army drove straight at the headquarters of China's 19th Army Group in Jiangxi Province. It was one of 22 major engagements between the National Revolutionary Army and the Imperial Japanese Army in the Second Sino-Japanese War. The Japanese called their operation Kinkō; the Chinese would remember it as Shànggāo Huìzhàn. What unfolded over the following weeks was a grinding contest of trenches, tanks, poison gas, and last-minute reinforcements that would end with one side walking away and the other left behind. How did an army outnumbered in firepower and equipment hold three defensive lines against tanks and air strikes? And what did victory at Shanggao cost the Chinese forces who won it?

  By March 15, the Japanese had seized the Chinese headquarters, but a Chinese air strike the same day destroyed Japanese food and ammunition reserves. That single strike demoralized the attackers and stalled their advance long enough for the Chinese to dig in. What they built was formidable: roughly 100,000 troops arranged across three main defensive lines of trenches reinforced with concrete-supported bunkers. The first line bore the initial Japanese assault. Dug-in troops with heavy machine guns turned the attackers back repeatedly, inflicting heavy casualties. The next day the Japanese advanced behind a smoke screen, reaching the Chinese positions and sparking vicious hand-to-hand fighting. Both sides bled badly, but the Japanese broke through the first line. After that breach, fighting paused while both sides attended to their wounded. The Japanese called in reinforcements; the Chinese quietly shifted troops from the third line forward to the second, preparing for what was coming next.

• 3. Tanks, Gas, and Retreat

  March 22 opened with a Japanese air strike that left between 100 and 200 Chinese soldiers dead or wounded. Then came the armored advance: tanks and armored cars leading infantry across open ground. Chinese defenders destroyed approximately half of the Japanese tanks and cut down the infantry following behind with small-arms fire. Forced to pull back, the Japanese switched to poison gas. The Chinese had already anticipated it. They abandoned the second trench line before the gas arrived and fell back to the third, keeping their casualties to a minimum. March 24 brought the largest Japanese push of the entire battle. Every remaining plane, tank, and infantry unit was committed to an all-out assault. The Chinese answered with mortars, machine-gun fire, and their own aircraft. Experts who studied the battle concluded that both sides suffered their heaviest losses that single day. Chinese general Zhu Xiang had rushed in reinforcements at the last moment, and the numerical advantage held. When the day ended, the Chinese lines had not broken.

• 4. The Withdrawal and Its Aftermath

  Japanese tacticians, reviewing their position after March 24, decided they could not afford further losses over what they judged an inconclusive fight for an enemy headquarters. On April 1 they began withdrawing. The retreat was hurried enough that the Japanese left weapons and wounded soldiers on the field; Chinese forces captured both. By April 19 the withdrawal was complete, with both armies back at their original positions. The cost on the Chinese side was 9,682 troops killed in action. From May 7 to the 10th of May 1941, the 19th Army Group held a memorial meeting for the fallen. On June 4, the Nationalist Government awarded the Order of Blue Sky and White Sun to Luo Zhuoying, the overall commander, and to Wang Yaowu, commander of the 74th Corps. Li Tianxia, who had commanded the 74th Corps's 51st Division, received the 4th grade of the Order of the Sacred Tripod. The 74th Corps itself was given the Flying Tiger Flag. The Japanese 11th Army emerged from Shanggao with a specific grudge: they designated the 74th Corps a sworn enemy and set their sights on that unit in the First Changsha Operation, known in China as the Second Battle of Changsha.
