In 1937, with the fall of Nanjing, Shiro Ishii, the notorious bacteriological warfare thinker and organizer, and his military medical officers began to seek to use Nanjing as a base to further expand the bacteriological warfare research network. On April 18, 1939, the "Central China Epidemic Prevention and Water Supply Department" was quietly established in Nanjing. The public name of this new unit was "Tama Force", and after December 1943, it was called "Noboru Force", sometimes it was also called "Hinoki Force", and its secret name was "Eiji Unit 1644". Rongzi Unit 1644 became the third important site of Ishii's bacteriological warfare research after Manchurian Unit 731 and Manchurian Unit 100. And Ishii himself served as the first captain of Unit 731 after serving as the captain of Unit 1644.

The headquarters of Unit 1644 is located on the site of the former Central Army Hospital in Nanjing (today's General Hospital of the Military Region and the Nanjing Radio Factory), that is, north of Zhongshan East Road in the center of the city. To the south of the road is the Ming Palace Airport, to the east is the military academy of the traitor puppet regime, and to the southwest is the air force dormitory. There are two main buildings within the boundaries of the headquarters of the unit, one is a six-storey building that houses the headquarters building, which houses the office of the commander and the offices of various administrative units; The other four-story building, which is an annex, is the heart of the army, because it is a cell for conducting bacteriological warfare research and holding "prisoners" for bacteriological experiments. In addition, the unit has also set up a subsidiary at the foot of Jiuhua Mountain, near Taipingmen, to the north of the headquarters, under the false name of "serum vaccine factory", which is actually a factory for the production of bacteria. In addition, Unit 1644 also set up 12 detachments in Shanghai, Suzhou, Changzhou, Hangzhou, Jiujiang, Nanchang, Anqing, Hankou and other places, with a total staff of about 1,500 people. Bacteriology, the Evil of Chemical Experiments and the Bestiality of Bacteriological Warfare The facilities of the Nanjing 1644 Bacteriological Unit, although smaller in size than the 731 and 100 Units, had a huge bacteriological production capacity. After Japan's surrender, the Chinese side cleaned up the "serum vaccine factory". At that time, there were still untreated media in the "manufacturing plant", including more than 30 tons of watercress (agar) and more than 100 boxes of fish essence paste. According to rough estimates, every 2~3 kg of agar can make 20~30 ml of bacterial suspension, and only the remaining batch of medium of the Japanese army is enough to produce 30,000 ml of bacteriological weapons that exterminate humanity. In addition, according to the Japanese bacteriological war criminals themselves, if all the equipment in Nanjing is activated, the Rongzi 1644 unit can produce 10 kilograms of bacteria in one production cycle. In parallel with the bacterial culture, Unit 1644 also carried out flea breeding, and about 100 gasoline drums were shared for the breeding of fleas. As the production cycle progresses, flocks of fleas swarm out of these gasoline drums, which bacteriologists use to test for plague.

Here we mainly emphasize that the Japanese army not only conducted experiments on animals, but, like the 731 bacteriological troops, conducted inhumane human experiments. For example, the injection test: the so-called prisoner is taken from the top floor of the four-story building mentioned above to the third floor, taken to the third floor of the laboratory, and then placed in a bed. The interpreter told him not to be afraid, and told him that the man in the white coat was a doctor who had come to Nanjing to "use medicine to cure you." Then, while the victim was not looking, the "doctor" quickly injected the victim with snake venom, cyanide acid or other poisons, and one of the "prisoners" was paralyzed just after being injected, and it took a few minutes for his heart to stop beating. For example, in order to verify whether the theory that arsenic hydrochloride can cause the heart to beat is correct, the bacterial experimenter fed the victim steamed buns mixed with arsenic hydrochloric acid, but the victim did not fall ill. Frustrated, the experimenter increased the dose again, but there was still no response. Eventually, the experimenters frantically increased the dose to a factor of 10. It is such a live experiment, which has been carried out every week by the Nanjing bacteriological unit for the six years of its existence. According to the American expert Harris, the number of deaths as a result of the experiment is estimated to be at least 1,200. In addition to conducting live experiments on bacteriological warfare, Unit 1644 also conducted live experiments on chemical warfare. Unit 1644 had a gas chamber with an observation window for human experiments. In order to verify that hydrogen cyanide acid is a potentially effective chemical weapon, Japanese researchers took the "prisoners" to the gas chambers and tied them to chairs. A "doctor" enters the gas chamber wearing a gas mask, opens the seal of the container containing hydrocyanide acid, and records the subject's distress before death.

Unit 1644, the third major link in the bacteriological warfare network, was primarily responsible for producing pathogens and experimenting with these products on prisoners, and it also actively participated in three of Shiro Ishii's most notorious bacteriological warfare experiments in Zhejiang. These three actual combat experiments were all carried out together with the Northeast 731 Bacteriological Unit. On October 4, 1940, the Japanese dropped wheat grains and millet seeds mixed with the "common fleas of humans and rats" infected with plague in Quzhou, Zhejiang. Thirty-eight days later, all 22 plague patients in the area died. On the 22nd, the Japanese army dropped fleas, wheat, and cotton infected with rat vaccines over Ningbo. Since then, plague has occurred in the area, infecting 99 people and curing only two people. In the same year, the Japanese army also dropped rat vaccines in Jinhua and other places, causing the spread of plague. In the spring of 1942, Unit 1644 and Unit 731 conducted the largest bacteriological warfare in the Zhejiang-Jiangxi region. The method is different from the last two airdrops, but more insidious. This time, the Japanese army threw bacteria into wells, swamps and houses, and also specially made some "egg-shaped, long-flat biscuits", infected with bacteria, and then let the soldiers distribute them to the Chinese. According to historical records in Zhejiang Province, from 1940 to 1944, 1.36 million poor people died of plague and other bacterial diseases in Zhejiang Province alone. In the spring of 1941, in order to destroy Changde, an important hub controlled by the Chinese army, and the areas along the communication route, Japan sent a second group of expeditions to sprinkle fleas with plague on airplanes, causing plague in the area and killing more than 400 people.

The Japanese High Command in China issued an order to destroy the various bacteriological factories on the spot, and the 1644 unit in Nanjing faithfully carried out this order. They spent more than 40 hours in three days and more than 40 hours to "burn not a single piece of paper" in two large cabinets. They killed all the prisoners, burned their bodies, and transformed the former cell into a recreation room. In addition, they dug up the bones that had been buried in the army station and burned them again, and threw the remaining ashes into the Yangtze River. The bones we mentioned earlier are the irrefutable evidence of the fact that the Japanese army forgot to burn them when they were in a panic.

After destroying the incriminating evidence, the main members of the Rongzi 1644 unit managed to return to Japan before the Chinese army entered Nanjing. At this time, the US military department, through on-the-spot investigation and the report of the Second Staff Office of the US Army Command in China, learned that the bacteria spread by the Japanese army in the 1942 Zhejiang-Jiangxi operation were produced by Unit 1644, and the plane carrying the bacteria also took off from the airfield south of the headquarters of Unit 1644. In addition, the former Soviet Union also sent information such as Japan's plan to conduct bacteriological warfare to the United States, and repeatedly demanded the extradition of Shiro Ishii and other bacteriological war criminals. But the United States refused to extradite and did not agree to a trial. It turned out that since 1942, the United States has also been secretly conducting research on bacteriological warfare, and many projects are similar to Japan's germ warfare experimental projects. As we all know, many of the results obtained from experiments on animals are not applicable to humans, and the results of Japan's bacterial experiments on Chinese are rare information for the United States, and the United States is eager to get these materials. Under these circumstances, MacArthur, commander-in-chief of the Allied forces in Japan, demanded that Ishii and others be exempted from responsibility as war criminals. In response to MacArthur's request, the Coordination Committee of the US State Department, the War Department, and the Navy Department studied and agreed with MacArthur's opinion, and made a promise to Ishii and others to be exempted from prosecution, and the United States also obtained all the materials on Japan's bacteriological warfare as it wished. The bacteriological war criminals, who had committed many crimes, were able to survive, and some even went back to their old jobs in the United States. This deal between the United States and Japan is a shame in the history of the United States and a blasphemy against the feelings of the Chinese people

Don't forget the past, the teacher of the future. Today, we expose the Japanese army's bacteriological unit in 1644 to remind the present generation and show future generations that they will never forget the cruelty, tyranny and cunning of the aggressors, and firmly remember the sacrifices, ravages and sufferings suffered by our people. Take history as a mirror, face the future, inspire the national spirit of self-esteem, self-confidence and self-improvement, and strive for the rejuvenation of China and the maintenance of world peace.

The top brass of the Northern Army was shocked when they saw this evidence, the Japanese militarists were extreme to the extreme, and they were mad, Li asked people to keep these evidence, take color photos with their cameras, and prepare to take them out later, most of the high-ranking officers of the Northern Army were very angry, and the historical culprits of later generations were shielded by the United States, Ma Zhanshan, Yao Luoqi, Zhao Sanduo, Li Xing, Zhang Kai, these people all said that it was time to go under the knife against the devil。。。。。。。

Li Ming also said that as long as Japan did not admit its guilt, the Northern Army would bring down the Japanese mainland, and now began to discuss the next operational plan for the Japanese-occupied areas。。。。。。。。。。

Commander Ma Zhanshan is the commander-in-chief of the Northern Revolutionary Army, Commander Zhao Sanduo, Commander Yao Luoqi is the deputy commander-in-chief, Commander Zhou Baozhong is appointed chief of the general staff of the Western Route Army, General Li San is the deputy commander-in-chief of the Western Route Army, and Li Xing is the commander of the First Army of the Northeast Police Force to assist Commander Ma's Northern Revolutionary Army in the offensive。。。。。。。。。
