The "8.4" incident provoked a great deal of indignation among the Chinese people. There was a huge outcry on the Web.
The Patriot Alliance, along with several other websites, organized a petition to put pressure on the Japanese government to compensate the victims. It initiated an online collection of 1 million signatures and is scheduled to deliver the petition to the Japanese Embassy in Beijing on September 18, the 72nd anniversary of the Japanese invasion of China.
After the "8.4" incident, a spokesman for the Japanese Ministry of Foreign Affairs made two written statements on the incident, and six experts dispatched by the Japanese government, accompanied by Chinese personnel, carried out a lead-sealed packaging of the gas barrels stored in the special goods warehouse in Fulaerki.
Since the Japanese government admitted that the "8.4" poison injury incident was caused by chemical weapons abandoned by the Japanese army, according to the strong demand of the poisoned victims and damaged units, the Chinese side has formally put forward a four-point request to the Japanese government through the Japanese government's investigative mission to the local government, but the Japanese government has not yet responded to the four-point request put forward by the Chinese side. The Japanese government has not yet responded to the four points raised by the Chinese side.
After 1931, Qiqihar city's eastern suburb of Bali Gang, once stationed a "731" troops with the same task of chemical defense forces, which is the invasion of the Japanese army in the Kwantung Army Army Institute of Chemical Research, code name "516". This unit was extremely covert, under the banner of scientific research, engaged in chemical weapons research, testing and manufacturing, with the Chinese people live body as a test, the crimes committed to this day.
Due to the deep concealment of the "516" unit, there are very few historical records of it, and on August 15, 1945, after the surrender of Japan, many of the unit's classified information was brought back to Japan, while most of the equipment and gas bombs were left behind in China.
When the infamous Japanese Kwantung Army unit "516" fled Qiqihar, most of the equipment and gas bombs were scattered and buried underground or thrown into the rivers. How many gas bombs did the Japanese army abandon in China? According to our army's chemical defense force repeatedly surveyed: Qiqihar underground at least 200,000 shells left behind by the Japanese army in China! Among them, it is difficult to estimate the number of gas bombs.
Japan's "Association for the Support of Victims of War in China" member Yukiko Yamabe, after a long investigation, collected a large amount of information to prove that the Japanese invasion of China abandoned in China throughout the chemical weapons amounted to 2 million, the Japanese government had to admit that there are 700,000.
From 1945 to 2003, more than 2,000 people in China have been injured or killed by toxic agents abandoned by the Japanese army.
The toxic substances used by the Japanese invasion forces in the war to poison people and animals and destroy the ecology are called military toxic agents, and artillery shells, rockets, missiles, and landmines equipped with military toxic agents are collectively known as chemical weapons. Chemical weapons are mainly poisonous gases, but also include all kinds of chemical weapons filled with smokescreen agents and incendiary agents. So far, there is no effective method or agent in the world for treating the harm caused by poisonous gases or chemical weapons to human beings. It is because of the great harm of chemical weapons, so it and nuclear weapons, biological weapons, side by side, become the contemporary international community in the relevant treaties prohibit the use of weapons of mass destruction.
As early as 1925, when the international community adopted the Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous, or Other Gases, and of Bacteriological Methods of Warfare in Geneva, the Japanese government, for the purpose of expanding its war of aggression against the outside world, secretly instructed its own military forces to begin the manufacture of chemical weapons on Okunojima Island in Hiroshima Prefecture. 1927 saw the Japanese Army move all of the inhabitants of Okunojima Island, and within two years the entire island was constructed into a massive chemical weapon factory. In 1927, the Japanese Army removed all the inhabitants from Okuno Island and, in two years, built a large-scale chemical agent and chemical weapon production plant on the entire island, and began to manufacture a variety of chemical weapons in 1929. Later, the Japanese Navy began to produce chemical weapons at the Sagami Naval Arsenal in Hanawa, Kanagawa Prefecture from 1943.
The chemical weapons abandoned by the Japanese Army in China were dominated by vomitory and vesicant agents, both of which are difficult to decompose and contain arsenic, which is a serious hazard to human health and the environment. Most of the chemical weapons that have been found abandoned by the Japanese army in China are non-storage type, with no protective layer on the exterior, and the corrosion has been quite serious unable to use machinery for automatic treatment. Since these CW have been buried in the ground for more than half a century, not only are they severely corroded, but some of them are already leaking slowly, and the explosives in them are still in danger of exploding. However, there are still some undiscovered chemical openings secretly buried or discarded by the Japanese army, and those poison bombs that have been discovered are still a great hidden danger due to the lack of effective means of disposal. Once the leakage occurs, it will certainly cause unimaginable harm to the local people's lives and property and the ecological environment.
After the "8.4" incident, the Chinese government emphasized the development of the situation and lodged a solemn protest to the Japanese government.
The Japanese government dispatched an investigation mission, medical and expert teams to the area. The Japanese side confirmed that the abandoned chemical weapons belonged to the old Japanese army. At a press conference on August 22, the official chief, Yasuo Fukuda, promised to take countermeasures and expressed "condolences" to the dead. But he made no gesture to accede to the victims' demands for compensation.
Under international pressure, the Japanese government finally recognized the existence of abandoned chemical weapons in 1991, and in 1999 it signed a memorandum of understanding between the Japanese and Chinese governments on the handling of abandoned chemical weapons. In the memorandum, the Government of Japan clearly stated that it would sincerely fulfill its international obligations under the Convention on the Prohibition of Chemical Weapons and provide all necessary funds, technology, experts, equipment and other materials for the disposal and destruction of abandoned chemical weapons. At the same time, a commitment was made to complete the disposal work by 2007.
However, the treatment of abandoned chemical weapons of the Japanese army has not seen any movement so far.
Mustard gas is one of the vesicant agents, and it is also the vesicant agent with the most use, the most common and the greater harm, so it is called "the king of vesicants".
Mustard gas was first produced by the Germans in 1886 in pure form, and was first used by the German army in World War I against the British and French forces in the Ypres region of Belgium. The scientific name of mustard gas is dichlorodiethyl sulfide. Pure mustard gas is a colorless oily liquid, and industrial mustard gas is yellow to dark brown, named for its mustard and garlic flavor.
Mustard gas can be loaded into shells, bombs and mines to be dispersed by explosion, and it can also be sprayed directly with equipment to the ground, air, water and objects to be poisoned. Mustard gas mainly invades the body through the skin or the respiratory tract and causes poisoning. After the incubation period of 212 hours, the skin will appear red, swollen, blisters, while the eyes appear blurred, red and even blind. In World War I, Hitler was attacked by mustard gas as a soldier in the war and was temporarily blinded.
Mustard gas injury pathway is more, when fighting, personnel must wear gas masks, wear protective clothing to protect.
When will the scourge of Japanese chemical weapons rest in China
According to statistics from the relevant departments, the areas where Japanese abandoned chemical weapons are found or suspected include Anhui, Hebei, Heilongjiang, Jiangsu, Jilin, Liaoning, Shanxi, Zhejiang and Inner Mongolia and a dozen other provinces and districts, of which the northeastern region is the most concentrated. The total number of gas bombs abandoned by Japan in China is about 2 million rounds. The Japanese government admits that there are 700,000 rounds, buried in Halba Ling about 670,000 rounds, Japanese experts from 2002 in the region with magnetic detection device survey results determined that there are 300,000 to 400,000 rounds.
As early as 1925, the international community in Geneva adopted the Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases, and of Bacteriological Methods of Warfare.
Almost at the same time, the Japanese government in order to expand the war of aggression, the secret order in Hiroshima Prefecture, Okinoshima Island, the manufacture of chemical weapons, and on the map to erase the island, through the island near the train is required to lower the curtains, do not allow the view, which is Okinoshima Island became known as "gas island," the origins of the...
Beginning in 1943, the Japanese again in the Kanagawa Prefecture, Sagami... Since 1943, Japan has been producing chemical weapons at the Sagami Naval Factory in Kanagawa Prefecture. According to the relevant materials in Japan, Japan was equipped with more than 1.9 million gas bombs fired from mortars all over the world, and in addition, Japan was equipped with 5.64 million "radiation cylinders" (cylinders in which poisonous gases were emitted to injure people). The Japanese believe that the 2 million rounds of gas bombs counted by China may have included the "radioactive cylinders".
The gas bombs were transported from Okushima to China, mainly to equip the 516th Japanese chemical unit in Qiqihar, which was a pair of devil brothers with the 731st unit. 1937 Japan set up the Kanto Technical Army, and two years later it developed into the Chemical Department of the Kanto Army, which consisted of the 516th unit and the 731st unit, both of which were chemical units. 516th unit was mainly used as a chemical weapon, and it mainly used poisonous gas such as mustard and Lewis gas. The 516th unit focused on chemical weapons, mainly using mustard gas, Louisiana gas and other poisonous gases, and the 731st unit focused on bacteriological warfare.
After the surrender of Japan, the Japanese militarists buried a large number of gas bombs in order to cover up their crimes, some of which were sunk under water, and some of which were put together with ordinary weapons. After the war, the Japanese Government had always denied the use of chemical weapons, and it was only in 1991 that it recognized the existence of this problem in the face of a large amount of human and material evidence and under international pressure. On July 30, 1999, the Governments of China and Japan signed a memorandum of understanding on the destruction of chemical weapons abandoned in China, in which the Government of Japan stated that it would fulfil its international obligations "in good faith" and provide all necessary funds for the disposal and destruction of chemical weapons. In principle, the disposal was to be completed by April 2007. However, as of 2005, Japan had excavated and destroyed only 37,000 gas bombs in areas other than Harbaling, which is too slow a pace of disposal. When will the 400,000 gas bombs be destroyed?
The abandoned chemical weapons are hard evidence of the heinous crimes committed by Japanese militarism in China. The war that pushed China into the abyss of disaster and inflicted far from recovering psychic injuries on the people has been over for 60 years, but the Japanese chemical weapons are still destroying the Chinese people's flesh and mind. Post-war gas bombs have hurt more than 2,000 Chinese people, the most recent is the August 4, 2003 Qiqihar Japanese gas bomb injuries, *** 43 people were injured.
Japanese director Tomoko Haenan made a documentary called "From the Land of Bitter Tears", which caused shock in Japan in 2004. The film takes Li Guoqiang and four other Chinese who were injured by the gas bombs as the protagonists, and tells the truth of the history of the Japanese army's invasion of China, and the fact that the abandonment of the chemical weapons is still harming the Chinese people today.
Those who were injured by the gas bombs had symptoms such as coughing, cardiopulmonary insufficiency, insomnia, vision loss, hair loss, etc. Some of them could not hold on to their jobs, and not only suffered unbearable pains themselves, but also brought endless sufferings to their families at the same time. The fact that so many people continue to be victimized more than half a century after the end of the war has shocked many Japanese as well.
The key issue now is that Japanese gas bombs may continue to hurt people. Japan has an obligation to deal with this issue as soon as possible. The Chinese government is y concerned about this, and China's Vice Foreign Minister Wu Dawei told a visiting Japanese Komeito Party member of the House of Representatives, Etsuhiko Endo, on December 1, 2005, that by 2012, it is hoped that this issue must be resolved.
August 18, 1998, some workers in Nanjing, a family dormitory compound in the north gate site construction, unintentionally dug up dozens of bones, by Beijing, Nanjing, experts in all aspects of the scientific examination, determined that these remains are dismembered and then scattered in the bushels, buried in a wooden box, the present time is about 60 years. At the same time, medical sampling and identification, determined that the "samples" contain Vibrio cholerae enterotoxin genes, and cholera bacteria is one of the deadly bacteria cultivated by the 1644th. According to the archives, there has never been a cholera pandemic in Nanjing since 1931. Therefore, it can be concluded that the remains found by the workers are the remains of the cholera bacterial toxin live test of the 1644th Nanjing unit of the invading Japanese army.
Japanese army set up 1644 Bacteriological Warfare Unit
The countries of the world signed the Letter of Agreement on the Prohibition of the Use of Poisonous or Analogous Gases and of Bacteriological Methods as early as 1925, which explicitly banned the production and use of bacteriological weapons. Japan refused to participate in the Agreement at that time, and openly risked universal condemnation by organizing extensive collection of information on bacteriological warfare and the manufacture of bacteria to implement its idea of developing bacteriological weapons and using them for aggression, because they believed that bacteriological weapons were an effective "weapon" for small countries to use against large ones.
In 1927, the Japanese Army Science Research Institute proposed a poison gas service establishment.
In 1932, according to the Emperor's decree, the Japanese Ministry of War set up the first bacteriological weapons research organization, "Bacteriological Research Class", which was called "Epidemiological Research Office".
In 1936, the infamous Unit 731 and Unit 100 were established in Harbin and Changchun, which were occupied by the Japanese army. In 1936, the infamous Unit 731 and Unit 100 were established in Harbin and Changchun, which were occupied by the Japanese, followed by Unit 1855 in Beijing, Unit 1644 in Nanjing, and Unit 8604 in Guangzhou. In 1942, the "Gonji 9420 Unit" was established in Singapore.
In 1937, Japan in North and Central China, the two major combat directions, respectively, the establishment of the first and second field chemical test department, and in China Shenyang, Taiyuan, Jinan, Nanjing, Guangzhou, Hankou, Yichang and other places to establish a field gas plant. Its chemical warfare troop establishment is more varied, mainly with poison gas alliance (at most 8 alliances put into the Chinese battlefield), brigade, squadron and poison gas command class, and so on.
On April 18, 1939, the Japanese bacteriological warfare war criminal Shiro Ishii personally established a bacteriological warfare unit with the number Nanjing "Ei" 1644, publicly known as "Tama Force", which was one of the three major bacteriological warfare units established during the same period in North China, Central China and South China. It was one of the three major bacteriological warfare units in North China, Central China and South China established during the same period. 1644 Unit also set up 12 branches in Shanghai, Suzhou, Changzhou, Hangzhou, Jiujiang, Nanchang, Anqing and Hankou, with a total of 1,500 people, directly belonging to the Ninth Doto Research Institute of Japan's Army Staff Headquarters, which was a conspiratorial assassination unit. The Eizo 1644 unit became the third important place for Ishii's germ warfare research after the Manchurian Unit 731 and Manchurian Unit 100. And Ishii himself became the first commander of Unit 1644 at the same time after serving as the commander of Unit 731.
The main headquarters of Unit 1644 was located in a six-story main building of the former Nanjing Central Army Hospital at 305 Zhongshan Road in Nanjing.
Behind the main building, a 4-story building is the secondary building, which was originally the Central Sanitary Experimental Hospital, where bacteriological warfare research and testing on living human beings were conducted. The first floor looks like an ordinary laboratory, is actually the study of cholera, typhoid and plague bacteria; the second floor is to keep rats and breeding fleas room; the third floor is the "prisoners" live test room; four that is, the top floor of the incarceration of "prisoners" and accept the test place, can accommodate more than 100 "prisoners". The fourth floor is the top floor where "prisoners" are imprisoned and tested, and can hold more than 100 "prisoners". Once a "prisoner" enters this place, it is impossible to get out alive.
The live subjects came from captives.
In 1941, human experimentation reached a climax, and they and their collaborators who came to Nanjing by ship from Japan, carried out heinous experiments, observed "prisoners" drinking venomous snake fluid, drinking anthrax culture fluid, for rabies in vivo infection experiments; centipedes, scorpions, pit vipers, and other small animals, venom and poisons injected into the living human body, to study its effect on the human body. Injecting venom and poisons from centipedes, scorpions, pit vipers and other small animals into the bodies of living people to study the pathological changes they produce; and the most brutal of all is to carry out experiments on chemical weapons, tying the "prisoners" to chairs in gas chambers, opening containers filled with hydrocyanic acid, and sealing them, so as to record and observe the pain of the experimental subjects before their deaths. Regardless of the success or failure of these studies, the subjects were killed and the remains were eventually thrown into an incinerator or buried in the ground.
In actual combat, the Japanese army used the type of poison to sneeze diphenylcyanoarsine (the Japanese army called "red 1") the most, accounting for 81% of the known cases of war; the use of lethal agents accounted for 19%. This was not due to humanitarian considerations, but to the fact that diphenyl arsine could quickly incapacitate unprotected soldiers; in addition, it was effective on the battlefield for a short period of time, usually within a few minutes, which made it ideal for Japanese infantry attacks.
In the 1941 battle of Yichang, the 9th Division of the 2nd Chinese Army attacked the city of Yichang, less than a kilometer away from the Japanese 13th Division headquarters, when the Japanese army was on the verge of extinction, so they burned secret documents and military flags, and senior officers were ready to commit suicide. In order to save the defeat, the Japanese army decided to use gas bombs to do the last struggle, in three days has carried out four large-scale chemical attack, and launched diphenylcyanoarsine toxic agent bomb 1500 rounds, mustard road mixed toxic agent bomb 1000 rounds, the aircraft dropped toxic agent bomb 300 rounds. In addition, toxic agent cartridges were used in large numbers. This resulted in a large number of casualties among Chinese troops and residents, including 1,600 poisoned and 600 killed in the 9th and 76th Divisions***. Due to the high casualties of the attacking forces, the counter-attack plan on Yichang failed.
October 1942, the autopsy room of "Unit 731" in Pingfang District, Harbin, China. A Chinese man infected with the bubonic plague is fastened to an autopsy table with his limbs tied. A Japanese surgeon uses a sharp scalpel to cut an oval shape in his chest and abdomen. The Chinese, who had exposed all of his internal organs, hissed "Ghosts!" Then he died of gas.
Standing in front of the autopsy table, Ryozo Shinotsuka's two legs kept trembling as he had to put the heart, liver, kidneys, and so on, taken out of a Chinese man's body, one by one, into glass bottles. By the time he dissected the third person, he could no longer feel the pain of killing.
In Unit 731, the Chinese and Soviets were called "logs", and the military doctors would use them to analyze the whole process of human infections with various bacteria, and produce data to create highly lethal bacterial weapons.
When Japan could not escape defeat on August 9, 1945, Unit 731 was in disarray trying to keep its germs and human experiments a big secret that violated international conventions.
Yu Yamamoto, who was driving in Unit 731 at the time, heard that the remaining 200 or so "logs" had been collectively locked up in a warehouse and gassed to death. The next day, Yamamoto received an order to drive a truck to an ad hoc prison. On the way, he saw black smoke rising from the prison yard. A few minutes later, he drove the truck, loaded with the bones of "logs" that had been burned to ashes, to the Songhua River to "dump" the bodies.
After Japan's surrender, the Chinese side cleaned up the "serum vaccine manufacturing plant". At that time, the "Manufacturing Institute" in the remaining unprocessed medium, there are more than 30 tons of Oriental vegetables (agar), more than a hundred boxes of fish paste. According to a rough estimate, this batch of culture medium was enough to produce 30,000,000 milliliters of genocidal bacteriological weapons. Also, according to the Japanese germ war criminals themselves, if all the equipment in Nanking was turned on, the Rongzhi 1644th unit could produce 10 kilograms of bacteria in one production cycle. While carrying out bacterial culture, Unit 1644 also carried out flea breeding. In order to propagate fleas, *** used about 100 gasoline drums.
The Japanese invaders not only experimented on animals, but also, like Unit 731, conducted inhumane human trials. Harris, an American expert, estimated that the number of people who died as a result of the experiments was at least 1,200.
Japanese army frantically waged germ warfare
The main duty of the Nanjing Bacteriological Warfare Base was to produce large quantities of fleas and pathogens and test these products for use in actual warfare, and the unit vigorously assisted the 731st Expeditionary Unit in conducting three major bacteriological campaigns since 1940.
The first was the 1940 plague war in Ningbo, Qu County, Jinhua, Yiwu and Dongyang in eastern Zhejiang. At that time, Ningbo was a deep-water port capable of navigating with foreign countries, and the Japanese army attempted to block the foreign passages with an artificial outbreak of plague epidemic in the place. The battle was conducted by the Japanese Kwantung Army, which issued Order C 659, with Ningbo and Qu County as the main targets of attack and Jinhua as an alternate. The latter two places are the key places in Zhejiang leading to Jiangxi, and later added Yushan, Wenzhou, Taizhou and other places.
On October 4, 1940, Japanese planes airdropped wheat and grains mixed with plague fleas in Qu County, after which the plague became epidemic. There were a large number of rats died, 20 days after the successive human cases, after three or four days are dead.
In late November, the plague patients gradually increased, spreading to neighboring areas.
Around 2 p.m. on October 27, 1940, Japanese planes dropped a smokescreen-like yellow fog in the Ningbo area. After a rustle, the ground was scattered with many wheat, corn and flour, especially a piece of blood red color is particularly eye-catching, that is a fat red fleas. After that, Ningbo area plague epidemic. According to statistics, the death of people at that time, soon Quzhou area also occurred a large-scale plague epidemic, the death toll of more than 2,000 people.
In early March 1941, the plague outbreak again, but also more and more popular, due to the frequent air raids by Japanese planes in Qu County County, so that the city people evacuated to the countryside, so the plague spread in the countryside, the number of deaths of at least 1,200 people. Qu County plague also spread to the neighboring county town of Yiwu and the county's Chongshan Village and the surrounding countryside.
The worst plague epidemic in Yiwu County was in Chongshan Village in Jiangwan Township, which suffered 369 deaths from October 1942 to January 1943, accounting for one-third of the total population at the time.
Chen Wengui, then an instructor of inspection science in the General Ambulance Corps of the Red Cross Society of China, proposed after careful research and analysis that it was likely to be the plague spread by the germ-carrying fleas used by the Japanese army.
Chen Wengui's words were shocking and disturbing to the authorities. The KMT government was afraid of the dire consequences if this fact came to light, so it did its best to block it. At the same time, Chen Wengui was warned that this was a military secret and was not allowed to be leaked.
The second was the 1941 plague war in the Changde area of Hunan province. Changde was a granary, a base for the Chinese army's military rations in central China as well as for food for the rear of Sichuan. If the use of bacteriological warfare plague rats along with the transportation of food, the plague will spread, even to the rear of Sichuan, which is of great strategic significance to the Japanese army.
This time Chen Wengui seized the opportunity to personally lead the investigation team to Changde to conduct field investigations and collect evidence.
Chen Wengui combined with many years of practical experience, based on the viewpoint of plague epidemiology, wrote the investigation report. He pointed out very definitely in the report that it was the Japanese army cast fleas with plague, which led to the plague epidemic.
This is an ironclad fact. However, the corrupt KMT government at that time disregarded the people's life and death, and still ignored it. Chen Wengui could only sigh with his wrists in the face of this mediocre KMT government.
Later, through the investigation, he found that a family had lost 11 lives in a few days to the plague bacillus put in by Japan, and at the beginning, he bought coffins and did Taoist work, but it was not long before the monks who did Taoist work were also infected and killed.
The third was the 1942 germ warfare on the Zhejiang-Gansu Railway line, which was a large-scale, multi-agent germ warfare. At that time, the U.S. Army, in support of China's war of resistance, sent out B25 bombers from Pacific ships and bombed more than a dozen cities in Japan, including Tokyo, Nagoya, Osaka and Kobe, and won. On their return trip, they took the route to land at various airports along the eastern coast of Zhejiang Province in China. In order to get rid of this hidden danger, the Japanese completely destroyed my three airfields along the Zhegan Railway (Qu County, Lishui, and Yushan), pincer attacking from the east and west, repelling the Chinese garrison and destroying the airfields and the railroad line. When withdrawing from the position, the Japanese army used a variety of bacterial warfare agents, spread from the air and ground, so that the above areas of plague, cholera and many other infectious diseases spread epidemic, so that the local Chinese soldiers and civilians were killed and injured.
The criminal Kudo Ryoio confessed in the Soviet military court: in the East China expedition led by Ishii, the use of typhoid and paratyphoid bacteria to contaminate cisterns and wells to carry out bacteriological attacks; the bacteria injected with a special 3,000 baklava, distributed to the 3,000 prisoners in the Chinese POW camps to eat, and photographs taken as the Japanese army to do charitable work to show off, and then all the people were released, the purpose is to cause typhoid fever and paratyphoid bacteria to spread. The purpose was to cause an epidemic of typhoid and paratyphoid fever, which was the most virulent.
The evidence of the crime is destroyed but the crime is in the history books
When the news of Japan's defeat came in 1945, the officers panicked and were in disarray. The Japanese high command in China issued the same order to all germ warfare units that all germ warfare factories must be destroyed immediately. The facilities on Zhongshan East Road in Nanjing were completely destroyed in the sound of explosions, including all top-secret documents and archival materials kept from 1939 to June 1945, which burned for three days and three nights, burning all the physical evidence of biochemical weapons and research records of in vivo experiments and studies used for bacteriological warfare.
A week later, there was a rumor that the Kuomintang government in Chongqing was going to send officers to take over, and the bacteriological warfare unit received an order: "All the germs, from fleas and rats to the living human body are all burned!" The corpses of more than one hundred people who had been gassed were piled up in a mountain, and after burning for several days, they were all thrown into the Yangtze River. Some of the bodies that were not incinerated were buried underground.
The main cadres of the Ei 1644 managed to escape back to Japan before the Chinese army entered Nanking. The second and third acting unit commanders, Masuda and Ota, and other senior colleagues also escaped capture, and some took up important positions after the war, such as president of a medical university and director of the Institute of Infectious Diseases. Only the fourth acting troop commander, Sato, was captured by the Soviets and tried by the Soviet military tribunal in Buri, and the last acting troop commander, Yamazaki Shin, was captured by the Chinese army and tried. Instead, Jintaro Ishida, the unit's draftsman, lived a life of seclusion, telling the world on his deathbed, "The atrocities committed by the Japanese army in Nanking were not just massacres, but the same acts of human experimentation, dissection of living human beings, and bacterial cultivation carried out by Unit 731 were likewise carried out in Nanking day and night." He told his relatives about the dark secrets of Unit 1644 "to bring the historical facts to light".
In addition to the bacterial warfare carried out by Unit 1644, there was also Japan's Unit 731, a unit specializing in bacterial warfare, which committed heinous crimes against the Chinese people.
The Japanese army as early as in the 1930s in some parts of China have been using bacterial openings systematic and large-scale implementation of bacteriological warfare is in the 1940s, the scope of the entire Chinese war zone, the use of bacteria, including anthrax, cholera, bubonic plague, dysentery, typhoid fever, paratyphoid fever, and so on almost at that time have a variety of fungi, and the Japanese bacterial weapons killed by the number of Chinese so far it is difficult to make accurate statistics, according to a more conservative estimate, the number of Chinese killed by bacterial weapons. In 1941, Japanese planes dropped a large number of fleas with plague bacillus in Changde, which led to the death of thousands of civilians from the plague, and the archives of the national government showed that hundreds of people died, but later, after an in-depth investigation, more than 7,600 people died in the plague, and more than 390 villagers in one village were spared except for one person who went out to work. The first time I saw this was when I was a student at the University of California, Berkeley, and I was a student at the University of California, Berkeley.
The notorious Japanese Kwantung Army 731, Kwantung Army 100 (beasts), East China 1855, Central China 1644, South China 8604, South 9420 and other bacteriological warfare forces and their branch forces in the Chinese land to carry out inhumane bacteriological human vivisection experiments and actual attacks, creating the darkest and most cruel war crimes in human history. After the war, the United States, in order to obtain the results of bacteriological warfare research and actual combat, harbored a large number of bacteriological warfare criminals, such as Shiro Ishii, so that the Japanese bacteriological warfare crimes could not be pursued and liquidated.
