The notorious "731" unit is the largest bacteriological weapons research, experiment and manufacturing base in the history of the world, the full name is the Japanese Kwantung Army stationed in Manchuria 731st epidemic prevention and water supply unit, under the pretext of studying the prevention and control of disease and drinking water purification, in fact, it is to use live Chinese, Koreans, frostbite, bacterial infection, poison gas experiments and other appalling biological weapons and chemical weapons research, the purpose of which is to plot to launch germ warfare to genocide.
Unit 731 was stationed in the Pingfang District of present-day Harbin, Heilongjiang Province, and at the time was under the jurisdiction of Manchukuo, a puppet regime supported by Japan. Unit "731" is the source of Japanese militarism in violating international conventions and launching germ wars, and is an important evidence of Japan's foreign aggression and expansion, plundering resources, and trampling on China's sovereignty. According to incomplete statistics, more than 10,000 Chinese and North Koreans were killed in the bacteriological test of unit 731.
As a special force of the Japanese army invading China to carry out germ warfare and the world's largest bacteria factory, unit "731" is under the dual leadership of the Japanese Army Province, the Japanese General Staff Headquarters and the Japanese Kwantung Army Command.
However, in September 1934, Liu Haitao, a general of the Anti-Japanese Coalition, led the Northeast Anti-Japanese Coalition Army to attack the infamous large-scale bacteriological weapons test site and rescued 16 Chinese compatriots, dealing a heavy blow to the Invading Japanese Army. Later, Liu Haitao reported the course of the operation to the Comintern, becoming the only anti-coalition general to invade the "731" unit and the first person to accuse the world of Japanese fascist germ warfare crimes.
After the "918" incident, Liu Haitao resolutely and resolutely joined the Northeast Anti-Japanese Coalition Army, because of his bravery and determination in battle, he was developed into a communist by the party organization, and gradually grew from an ordinary soldier to the commander of the 1st Regiment of the 1st Division of the 3rd Army of the Northeast People's Revolutionary Army, leading the troops to open up the anti-Japanese guerrilla zone in the North Manzhu River, repeatedly building up battle achievements and shocking the enemy.
In September 1934, Liu Haitao led his troops to the east of Harbin to launch a guerrilla war against the Japanese army.
When he arrived, Liu Haitao learned from the local population that there was a "magic cave" near Shuangcheng County, southeast of Harbin, which everyone talked about, mysteriously, and the Japanese army would transport truckloads of villagers and Chinese soldiers from all over the country every day, and these people would never see them again after they went in.
This "magic cave" is the infamous "731" germ unit of the Japanese army invading China.
Liu Haitao concluded with the eyes of a soldier that this "magic cave" is definitely not a good kind, it must be a secret base of the Japanese army, maybe it will be the ammunition depot or supply station of the Japanese army, that is too good, his troops are lacking weapons, ammunition and food. Therefore, Liu Haitao decided to end this "magic cave" that everyone talked about.
After several days of reconnaissance, Liu Haitao led the 1st Regiment of the 1st Division of the 3rd Army of the Northeast People's Revolutionary Army to quietly come to the back of the River in the east of Shuangcheng County and launched a surprise attack on the "Magic Cave".
The battle went very smoothly, and the 1st Regiment soon attacked the inside of the "Magic Cave", but found that this was not the imaginary Japanese ammunition depot or supply station, so Liu Haitao did not love the battle, and after the coincidence of rescued 16 Chinese compatriots who escaped from the riot, he led the troops to retreat before the arrival of the enemy's reinforcements.
Afterwards, Liu Haitao learned from the 16 compatriots who were rescued that this "magic cave" turned out to be a large-scale bacteriological weapons testing ground for the Japanese army invading China, and the unit stationed there was the notorious "731" unit in the future.
Liu Haitao regretted very much that he did not end this bacteriological weapons test site.
In November 1934, Liu Haitao led the 1st Regiment to launch a surprise attack on the Japanese army in Xiaotiandi and Taipinggou, annihilating a large number of Japanese troops and rescuing Zhao Shangzhi, one of the founders and leaders of the Northeast Anti-Japanese Coalition Army and one of the earliest Communists in the northeast region, who was deeply besieged and seriously wounded by the Japanese army.
At the beginning of 1935, Liu Haitao led the 1st Regiment to unknowingly launch a surprise attack on the Japanese army in Wahong, Nandiaoling, Linkou, Erdaohezi and other places, eliminating countless Japanese troops, capturing more than 200 guns of various kinds, hundreds of thousands of bullets, hundreds of warhorses, and more than 500 sets of cotton military uniforms, and countless other strategic materials, which greatly alleviated the plight of the troops' lack of food and clothing and ammunition, and successfully opened up guerrilla areas such as Yanshou and Fangzheng and expanded the anti-Japanese base areas.
In October of the same year, Liu Haitao commanded the troops to set up an ambush near The Fangzheng Sandaotong in central and southern Heilongjiang Province, successfully blew up two logistics supply ships of the puppet army in Yilan County, completely annihilated the puppet army, and captured more than 330 sets of cotton uniforms, more than 500 yuan in cash, 20 rifles, and more than 30 bags of flour, laying a solid foundation for the troops to successfully survive the winter.
At the end of 1935, the Northeast Anti-Japanese League sent Liu Haitao to study in the Soviet Union. After arriving in the Soviet Union, Liu Haitao reported to the Comintern on his battle against the large-scale bacteriological weapons test site of the Invading Japanese army in Shuangcheng County, Harbin, and accused the people of the world of the heinous crimes of the Japanese fascists in killing Chinese people.
In 1938, Liu Haitao returned to China after completing his studies and was cordially received by Mao Zedong, Liu Shaoqi and other leading comrades of the Party Central Committee in Yan'an.
In 1939, Liu Haitao was ordered to come to Shandong, and successively served as the commander of the sixth and ninth detachments of the Shandong Column of the Eighth Route Army, the deputy brigade commander of the second brigade, and the commander of the Luzhong Military Region.
In the autumn of 1941, during the anti-"sweeping" battle, Liu Haitao was unfortunately wounded and captured by the Japanese army. On November 25, the indomitable Liu Haitao was brutally killed by the Japanese army in Yishui, Shandong Province, at the age of 34.
Liu Haitao was the highest general of the Northeast Anti-Japanese League who died in Guannei during the War of Resistance Against Japanese Aggression.
Luo Ronghuan was so saddened by the loss of his beloved general that in a telegram to the Party Central Committee and Chairman Mao, Liu Haitao's sacrifice was listed as one of the most serious losses in Shandong in 1941.
