The Zhejiang-Jiangxi campaign or the Chekiang–Kiangsi campaign (Japanese: 浙贛作戦, ), also known as Operation Sei-go (Japanese: せ号作戦), was a campaign by the China Expeditionary Army of the Imperial Japanese Army under Shunroku Hata and Chinese 3rd War Area forces under Gu Zhutong in Chinese provinces of Zhejiang and Jiangxi from mid May to early September 1942.

Hata's forces launched the campaign in retaliation for the Doolittle Raid, conducted by American pilots who had then landed in China's Zhejiang and Jiangxi provinces. Besides seizing local airfields, Japanese troops launched massive reprisal campaigns against the local population by "slaughtering every man and child." Anywhere from over 20,000 to as many as 250,000 Chinese died in the Japanese reprisals, the majority civilians.

Background

On April 18, 1942, the United States launched the Doolittle Raid, an attack by 16 B-25 Mitchell bombers from the aircraft carrier on Tokyo, Nagoya, and Yokohama. The original plan was for the aircraft to bomb Japan and land at airfields in unoccupied portion of China. Because the raid had to be launched earlier than planned, all but one of the aircraft (which against orders diverted to the Soviet Union) ran out of fuel and crashed in the Chinese provinces of Zhejiang and Jiangxi or their offshore islands.

Sixty-four American airmen parachuted into the area around Zhejiang. Most were given shelter by Chinese civilians but eight Americans were captured by Japanese troops; three were shot after a show trial for crimes against humanity. The campaign Imperial General Headquarters was aware of possible air attacks from Chinese territory on Japan. Two days before the Doolittle Raid, Headquarters set up an operational plan with the goal of defeating Chinese forces and destroying air bases. The operation started on May 15, 1942, with 40 infantry battalions and 15–16 artillery battalions of the Imperial Japanese Army., p.28

On May 15, the main force of the Japanese 13th Army invaded westward along the Zhejiang-Jiangxi Railway and both sides from Fenghua, Shangyu, Shaoxing, Xiaoshan and other towns in Zhejiang. Commander Korechika Anami of the 11th Army commanded two divisions and four detachments to advance from east to west from Hangzhou and Nanchang to attack in the direction of Shangrao, Jiangxi. On August 15, the Japanese army was ordered to retreat, and the Chinese army followed and pursued them. By the end of September, except for Jinhua, Wuyi and the northeastern region, all along the Zhejiang-Jiangxi Railway had been recovered.熊武一,周家法 总编;卓名信,厉新光,徐继昌等 主编.军事大辞海·下.北京：长城出版社.2000.第2550页

Japanese troops conducted a massive search for American airmen and in the process whole towns and villages that were suspected of harboring the Americans were burned to the ground and many civilians executed. The Japanese also wanted to occupy the area to prevent American air force from ever using airfields in China that could put the Japanese mainland within reach.

Aftermath When Japanese troops moved out of the Zhejiang and Jiangxi areas in mid-August, they left behind a trail of devastation. In Yihuang County, Japanese troops killed all orphans and the elderly sheltered at a missionary station. In that case, Japanese soldiers had bayonetted the victims, or tied them to stakes and burned them like "human candles".books.google.com/books?id=VH_hDwAAQBAJ&pg=RA1-PT68 In other cases, Japanese soldiers threw children into wells and drowned them.books.google.com/books?id=ZPAeEQAAQBAJ&pg=PT162

Claire Chennault reported 250,000 Chinese deaths from Japanese reprisals during the campaign. In 1943 after escaping pursuing Japanese troops in China, Vincentian Father Vincent D. Smith reported to American newspapers that Japanese troops had murdered more than 250,000 Chinese civilians in their search for Doolittle's flyers. American Historians James M. Scott, Richard Frank, and John A. Haymond also cite this figure.

The Record of Battles on the Main Front of the Chinese War of Resistance Against Japan authored by Lieutenant-General Guo Rugui and Huang Yuzhang states that in Quzhou alone over 20,000 civilians were murdered, another 30,000 were captured and went missing, and over 100,000 houses were burned down. The official Chinese records of losses within Zhejiang Province record at least 66,526 civilians killed, wounded, or missing in 1942—noting this accounted for over 21% of the province's direct casualties as a result of the war and was largely due to the campaign. Zhejiang's records further indicate the worst massacre occurred on August 25 1942 when around 300 civilians were killed by Japanese troops attacking from Songyang County. Jiangxi Province's official records provide no yearly data on civilian deaths, but note that in June 1942 Japanese troops killed more than 50 civilians in Linchuan County and another 136 villagers hiding near Xuija Village (Chinese: 徐家村) on June 19 1942.

The Imperial Japanese Army had also spread cholera, typhoid, plague-infected fleas and dysentery pathogens.Yuki Tanaka, Hidden Horrors, Westviewpres, 1996, p.138 The Japanese biological warfare Unit 731 brought almost 300 pounds of paratyphoid and anthrax to be left in contaminated food and contaminated wells with the withdrawal of the army from areas around Yushan, Kinhwa and Futsin.Scott, James M., Target Tokyo, W. W. Norton & Co., 2015, p.387 This attack took place at Jinhua in Zhejiang and the Japanese soldiers inadvertently advanced in the area they spread with biological weapons and got themselves infected, leading to over 1,700 dying and 10,000 getting sick. This information about the Japanese killing their own soldiers in the campaign came from a Japanese POW captured by Americans in 1944, who admitted that the actual Japanese death toll was far higher than the 1,700 he saw on the documents at the biological warfare headquarters, and that Japanese regularly downplayed their own casualties:

Chinese casualties According to the statistical table of casualties from the "History of the Anti-Japanese War", the casualties of the headquarters and directly subordinate units of the 88th Army, Qiantang River Northern Army, and 21st Army, the 52nd Division, the 148th Division, three battalions of the 192nd Division, and all engineer, artillery, and communications units except for engineer and artillery units attached to the 86th Army at Quzhou were not reported and thus not included in the statistics. The NRA war history book recorded the losses of the 40th Division at 200 killed, 275 wounded, and 539 missing, the 19th Division at 204 killed, 188 wounded, and 34 missing, and the 75th Division at 384 killed, 147 wounded, 708 missing. According to Gu Zhutong's report on September 28, 1942, the 19th Division suffered 381 killed, 333 wounded, and 18 missing and the 75th Division suffered 766 killed, 302 wounded, and 1,517 missing. The same telegraph also reported the losses of the headquarters of the 28th Army which was not included in the "History of the Anti-Japanese War" at 3 wounded and 124 missing.國史館檔案史料文物查詢系統，顧祝同電蔣中正浙贛戰役參戰暫三十二師暫三十三師第十九師等部隊官兵傷亡失蹤損耗情形彙報，典藏號：002-090200-00076-139 Gu Zhutong also reported on August 4, 1942, that by August 1, the 40th Division had suffered 267 killed, 348 wounded, and 1,064 missing.國史館檔案史料文物查詢系統，顧祝同電蔣中正第三戰區五十軍二十五軍二十八軍七十軍及挺一縱隊現存戰力及官兵傷亡損耗情形，典藏號：002-090200-00076-137 An earlier report put the losses by June 30 at half for the 40th Division and two-thirds for the 75th Division while the 19th Division remained intact.國史館檔案史料文物查詢系統，賀耀組電蔣中正第三戰區此次作戰各部隊損耗及現有實力概況表，典藏號： 002-020300-00014-059

The casualties of guerrilla units such as the Loyalty and Bravery Army and Chen Tianqiao's Siming Mountain guerrilla force in Zhejiang Province, which were included in the order of battle, were not included in the casualty statistics of the war history. The casualties of the 183rd Division, New 12th Division, New 20th Division, and Jiangxi peace preservation regiments in Jiangxi Province were also not included in the statistics despite the latter unit in particular being heavily engaged. Excluding the Iwanaga task force which fought against solely the Chinese 75th Division, the other two divisions, five task forces, and one battalion of the Japanese Eleventh Army all recorded fighting against the Jiangxi peace preservation regiments with the only recorded opponent of the Hirano task force and the Takahashi battalion being that Chinese unit.
