During the Battle of Wuhan, what was the purpose of the Soviet Union sending troops to Zhang Gufeng, and what was the result of the Japanese-Soviet war?

During the battle of

in Xuzhou, Chiang Kai-shek and always wanted to obtain the support of the Soviet Union. Apart from the resources of strategic materials, the Soviet Union had always stood still. But during the Wuhan battle and , in the summer of 1938, the Soviet Union suddenly sent troops to Zhang Gufeng. What was his purpose? Why did the Japanese army in its heyday lose to the Soviet Union?

​​On May 12, 1938, the minister of the Soviet Far East, Samoylovich Rushkov, suddenly defected to Manchuria. As a senior official of the Soviet Union, he had a lot of intelligence in his hands, including the Soviet Union in the Far East Siberia. The garrison establishment, designation, and military radio codes in use. This guy


​​directly sold all the information to the Japanese. When the Japanese learned that the Soviet army deployed in the Far East, with a total force of more than 500,000 and more than 2,000 fighter jets, the Japanese army received a great shock. At this time, the total strength of Japan in North Korea and China is less than 200,000. If large-scale military operations are launched in the Far East, the situation of the Japanese army can be imagined.

​​The battle of Wuhan in China is about to begin. In order to avoid the predicament of getting into a two-front battle, Japan sent spies to sneak into the Soviet defense zone near Zhanggufeng to investigate. The result was tragic. The Japanese spy was discovered by the Soviet border defense force in a gun battle between the two sides. The spy leader Matsushima was killed. This was the fuse of the Zhang Gufeng incident.

​​Zhanggu Peak is located on the Sino-Russian boundary 1.5 kilometers north of Fangchuan Village, Jingxin Town, Hunchun City, Jilin Province. It is such a place that can't be found on the map. A lot of things can happen in history. In the "Aihui Treaty", Zhang Gufeng is Chinese territory, but in the Russian Sakamoto treaty, Zhang Gufeng belongs to Tsarist Russia.


​​In 1932, after the establishment of the Puppet Manchuria, Zhang Gufeng has always been regarded as his territory, and it was classified as Aihui County. In the eyes of the Japanese army, Zhang Gufeng, from a legal point of view, belongs to the Puppet Manchukuo. It overlooks the three countries of China, the Soviet Union and the DPRK. The terrain is very narrow and cannot carry out large-scale operations, because the Japanese army wants to conduct a battle here. Touch the strength of the Soviet Union.

​​Due to the strength of the Soviet Union, the Emperor of Japan has always disagreed with sending troops, but the Japanese army has always had a tradition of "undergoing overriding". The commander of the 10th Division, Odaka Kamezo, came directly with a "will be out, the military life is not affected", and directly excluded 4 infantry squadrons, 2 mountain artillery groups, 1 field heavy artillery group, about 1,700 people The strength of the troops directly advances the border areas.

​​On July 30, the Japanese army secretly crossed the river and evacuated the old women and children, leaving only the young and middle-aged to carry water and deliver ammunition for the Japanese army. On July 31, Japan bombarded Zhang Gufeng, and then two infantry battalions under the cover of artillery began to attack, and on August 1, occupied Zhang Gufeng.


​​On August 2, the Soviet army began to counterattack. The first wave of attacks sent 10 bombers to directly carry out a large-scale bombing of Zhang Gufeng. It turned out that the Japanese army had only one division and a few border troops in this area. After Japan launched its offensive, the Soviet Union immediately sent reinforcements, two infantry divisions and one mechanized brigade.

​​Overall, in the Zhanggufeng area, the Soviet Union has concentrated 15,000 people, 237 artillery, 258 tanks, and 250 aircraft, while the Japanese army has only 7,000 people, 37 artillery, and 70 aircraft. From here, you can It can be seen that the strength of the Japanese and Soviet armies is very different. The two armies fought until August 4. On the surface, the Japanese army had the advantage and did not lose its position, but in fact, the Soviet Union had cut off all the railways and the Japanese supply line. On August 5, the Japanese army telegraphed the Tokyo base camp, hoping to start diplomatic negotiations, which is actually a disguised stop of military operations. For various reasons, the order from the base camp was delayed for several days, which directly caused the Japanese army to suffer heavy losses.


​​On August 6, the Soviet Union launched a general offensive. Under the cover of 70 fighters, 180 bombers directly bombed the Japanese position at Zhang Gufeng, followed by artillery, infantry, and hand-to-hand combat. On August 9, the Japanese were attacked. All expelled from Zhang Gulou.

​​On August 10, Japan and the Soviet Union signed the "Zhanggulou Armistice Agreement", on August 11, Liang JunFrom the Zhanggufeng position, each retreated 80 meters. On August 13, Liang Jun exchanged prisoners of war and the bodies of fallen soldiers.

​​So far, the Zhanggulou incident has officially ended.
