After the September 18 Incident, the Japanese army occupied the northeast of the mainland and then began to border the Soviet Union. Stationed in the northeast is the Kwantung Army, known as the flower of the Imperial Army, and its combat effectiveness is very strong. At that time, there were two kinds of decisions in Japan, one was to move south and the other was to move north. Among them, the northward advance was to attack the Soviet Union, and the Kwantung Army has always advocated the northward advance. Finally, in 1939, the group began to attack the Mongol region, trying the water first, and preparing for the northward advance.
In May 1939, the Japanese Kwantung Army decided to first attack the Mongolian People's Republic in the area of Nomonhan and occupy its eastern territory of Halaha as a springboard for the next step of intrusion into the Soviet Far East, thus realizing the long-planned "northward expansion plan". Japan has been planning this northward advance for a long time, and it is confident. Realistically speaking, the Japanese plan is indeed very rigorous, and the strategic and tactical arrangements are very good. In a very short time, the Japanese army copied the Soviet army from the north and south. At this time, for the Japanese army, it is to shrink the encirclement circle, completely annihilate the encircled Soviet army, and annihilate the Soviet army, they can really say that it is inevitable.
However, there were always accidents, and the Japanese army was very unlucky and encountered Zhukov to direct the battle. It should be known that during World War II, Zhukov was the commander of the Soviet army, known as Stalin's firefighter, and went wherever there was a need. Zhukov's style of playing this battle really reflected the strength of Soviet industry. The Soviet Union invested 524 tanks, 385 armored vehicles, 542 suppressed artillery pieces, and 500 aircraft. Throughout the campaign, the Soviets had more than 7 to 1 superiority in the number of tanks and armored vehicles, 6:1 in the number of artillery, and 3:1 in strength, and in the total offensive, 524 tanks were put in, 385 armored vehicles, 542 suppressed artillery pieces, and 500 aircraft were put in. Throughout the campaign, the Soviets had more than a 7-to-1 advantage in the number of tanks and armored vehicles, a 6:1 advantage in the number of artillery, and a 3:1 superiority in strength. It would also be said that in all respects, the Soviet Union and the Japanese army are not the same level. For Japan, what was thought to be a foregone conclusion was that stealing chicken did not become a corrosive rice, and almost put itself in. He was beaten by the Soviet Union. The Japanese had to stop fighting. On September 9, Dongxiang's ambassador to the Soviet Union requested an armistice in Nomonhan to the Soviet Union. The two countries then signed an armistice.
Looking at the normal campaign, under such a large disparity in firepower and personnel, the Japanese army fought very well. The reason why the Japanese army did not continue to fight was because it was frightened by the Soviet way of playing, and the Soviet Union's firepower was too fierce, which the Japanese army did not expect. And the Soviet Union also relied on this battle to make Japan dare not provoke itself throughout World War II, and it was really scared.
