During the War of Resistance Against Japanese Aggression, the Kuomintang army defeated Japan less and lost more, and in the Battle of Lanfeng, the Kuomintang 150,000 troops opposed the 20,000 Japanese troops of the 14th Division of Toihara, not only failed to eat the Japanese army, but were beaten badly by the Japanese army, and even had to cut open the Yellow River embankment to drag the Japanese army forward.

In June 1938, under the onslaught of the 14th Division of Tufeiyuan, the fall of Kaifeng was a foregone conclusion, followed by the crisis in Zhengzhou, and Wuhan was also shaken, and Jiang Ren, who was poor in donkey skills, actually thought of replacing the troops with water, and cut open the Yellow River levee to slow down the speed of the Japanese army's advance.
So which section of the Yellow River levee was opened? Who will do it? Jiang First gave an order to the Shang Earthquake Department stationed at the Zhaokou Embankment, who knew the consequences of breaking the levee and chose to start construction in a place where the sediment was silted up during the execution, and the progress was very slow, which was a disguised disobedience.
Jiang Someone knew that the Zhaokou embankment would not work, so he gave the task to Jiang Zaizhen, who was stationed near the Garden Mouth, and later Jiang Zaizhen chose the location of the excavation embankment west of the Zhaokou through research, and after 2 days and 2 nights of excavation, in the early morning of June 9, 1938, the Garden Mouth Embankment was excavated.
The garden mouth breach led to the death of hundreds of thousands of people, the people affected by its disaster are difficult to count, this incident was ordered by Jiang Someone, the execution was Jiang Zaizhen, the two together directed this "natural disaster", and also put the account to the head of the Japanese army, I have to say that Jiang Someone is clever.
On the morning that the Huayuankou embankment was opened, Jiang Zaizhen sent a telegram to Jiang Zaizhen, in which Jiang Zaizhen said that three Japanese bombers had blown up the Garden Mouth, and he himself was leading troops to repair the mouth, after which the Kuomintang news agencies all claimed that the Japanese army had blown up the Garden Mouth.
As the executor of the garden mouth levee, what happened to Jiang Zaizhen? During the War of Resistance Against Japanese Aggression, Jiang Zaizhen was reused, and his performance was not bad, he was the commander of the new 8th Division of the Kuomintang at the time of the embankment, and then he was transferred to Hancheng in Shaanxi to guard Yumen, also known as Longmen.
On December 26, 1938, the Japanese army dispatched two companies and a brigade, plus 5,000 puppet troops to attack the positions defended by the New 8th Division.
Jiang Zaizhen commanded the officers and men of the New 8th Division to resist bravely, repelling more than 70 Japanese attacks, and the casualties of officers and men in the forward positions reached more than 70%, one of the reinforcement platoons was all killed, and a soldier was wounded and flowed out of the intestines, wrapping his intestines around his waist and continuing to fight until he was killed.
Under the stubborn resistance of the New 8th Division, the Japanese army was never able to cross the Yellow River, the right wing of the Second Theater was guaranteed, and it also indirectly defended the Shaanxi-Gansu-Ningxia Border Region.
After that, Chiang Zaizhen led the new 8th Division to participate in the counterattack on Guilin, Jeonju and other battles, and fought against the Japanese army, in 1947, Jiang Zaizhen was promoted to lieutenant general and transferred to the general office senator, so that The bright rise and secret demotion made Jiang Zaizhen very angry and did not go to office.
In 1949, before the Defeat of the Kuomintang, Jiang Zaizhen was reactivated as deputy commander of the Second Appeasement District of Guizhou, and on the eve of the liberation of Guizhou, he revolted with his troops and served as the vice chairman of the Zunyi Bandit Suppression Committee in New China.
On September 14, 1952, Jiang Zaizhen was tried at Zunyi Memorial Square and sentenced to be shot, and then in a vacant lot on the south side, Jiang Zaizhen was shot on the spot at the age of 56.
