The battle on the east bank of the Krulun River, 15 kilometers east of the city of Choibalshan in Outer Mongolia, was the only large-scale battle between the Chinese People's Liberation Army and the former Mongolian People's Revolutionary Army in the course of its march into the Outer Mongolia region to perform its defense tasks. The First Army of the Chinese People's Liberation Army quickly wiped out the Mongolian 5th Cavalry Division, the most powerful elite division of the Mongolian People's Army, and the heavy artillery battalion of the 9th Mechanized Infantry Division of the Soviet 57th Army stationed at Choibalshan. It reflects the determination and will of the Chinese political axe and the Chinese people to safeguard national unity and territorial integrity by any means. The 1st Armored Division of the 1st Group Army on the East Road, the 1st Public Security Division of the Inner Mongolia Armed Police, and the 1st Division of the Inner Mongolia Army Reclamation took over the eastern part of Outer Mongolia smoothly and quickly marched to the northeastern border of Outer Mongolia to perform defense tasks, ready to start with the "big brother".

On the western route, the 1st Mechanized Infantry Division of the 5th Group Army and the 1st Reserve Division of the Xinjiang Provincial Production and Construction Corps marched into the western part of Outer Mongolia from the area north of Ayutai in two routes to the predetermined target. On the night of the start of the operation, the army aviation brigade landed in the Chagan Ur area, the junction of the highway between western Mongolia and the Soviet Union, and the Khanhe area, the junction of the highway connecting the northern part of the Soviet Union and the Soviet Union, and first cut off the two highways to the west and northwest of the Soviet Union and Outer Mongolia, thus blocking the border between the Soviet Union and Outer Mongolia. The 1st Mechanized Infantry Division of the 5th Group Army and the 1st Reserve Division of the Xinjiang Provincial Construction Corps traveled along the highway in western Outer Mongolia day and night, arriving at the designated position as scheduled at a speed of more than 200 kilometers a day, taking over the western part of Outer Mongolia and comprehensively fulfilling the task of defending the western and northwestern borders of Outer Mongolia.

In the middle road, the 2nd Mechanized Infantry Division of the 1st Group Army, the 3rd Mechanized Infantry Division and the 1st Division of the Inner Mongolia Armed Police Public Security, marched into Outer Mongolia at the fastest speed, they bloodlessly occupied the Outer Mongolia Zamyn-Uud connected to Inner Mongolia Erenhot, and then marched to Ulaanbaatar by train, in order to protect the safety along the railway line from Erenhot to Ulaanbaatar, Deng Feng's Far East Corps in addition to using two drones to conduct strict reconnaissance and monitoring of the surrounding area of the railway, but also sent four armed helicopters to patrol along the line. To ensure that this only railway artery is foolproof.

Everywhere the Far East Corps went, except for the former Mongolian People's Revolutionary Army, which belonged to the "returnees" led by Danba, it did not disarm the rest of the armed forces, arrested the military advisers of the Soviet Army stationed in the former Mongolian People's Army, and dispatched reorganized personnel to the former Mongolian People's Revolutionary Army to resolutely suppress those diehards who insisted on [***].

After the 2nd Mechanized Infantry Division and the 3rd Mechanized Infantry Division arrived in Ulaanbaatar, the 2nd Mechanized Infantry Division quickly moved westward to occupy Hutag as planned, and then turned northeast and penetrated directly into the border city of Sukhbagar between the Soviet Union and Outer Mongolia to encircle the headquarters of the 9th Mechanized Infantry Division and 4 regiments of the 57th Army of the Red Banner Far East Military Region of the Soviet Union stationed in the area north of Ulaanbaatar. The 3rd Mechanized Infantry Division took over the defense north of Ulaanbaatar from the former Mongolian 1st Cavalry Brigade north of Ulaanbaatar. Advance in the direction of Sukhbagr City, compress the activity space of the 9th Mechanized Infantry Division of the Soviet Army, and encircle the 9th Mechanized Infantry Division of the Soviet Army with the 2nd Mechanized Infantry Division. Forcibly disarm it.

Eight hours after the start of the "Return Operation", the Far East Corps of the Chinese People's Liberation Army took control of the main strategic points and communication arteries in Outer Mongolia. This was a typical campaign organized by the Far East Corps in which all arms of the armed forces combined with mechanized group attack groups attacked. The operation used a total of 4 mechanized armored divisions, 1 airborne division, 2 armed police and public security divisions, 3 logistics support divisions of the production and construction corps, a total of 10 divisions, and two army aviation brigades. More than 200,000 people, more than 400 "Destroyer" tanks. More than 500 "Raider" wheeled armored vehicles, more than 9000 vehicles of various kinds. Due to the rapid attack, the Soviet Union did not have time to make any response, and the takeover of Outer Mongolia by China became an established fact.

On May 20, 1958, Danba, the former first secretary of the Mongolian People's Revolutionary Party, announced the dissolution of the Mongolian People's Republic after 34 years of reading, and the merger of Inner and Outer Mongolia to form the Far Eastern Province of the People's Republic of China. Danba became the first governor of the Far Eastern Province and the deputy secretary of the Far Eastern Provincial Committee of China. The return of Outer Mongolia is an international political event of great significance, marking that China has begun to clean up the "bad debts" left over from history. The rifts within the international [***] movement have come to the fore. Whether this can lead to a new world war, and whether or not a nuclear war can be caused between these two [***] nuclear powers, has become the focus of the world's attention.

The Wall Street Newspaper in the United States carried the headline "China's lightning attack on Outer Mongolia, the world was shocked!" As the title, exclaimed: "The world is shocked by this! Without hesitation, the Chinese [***] people overturned the unequal treaties imposed on them by Stalin, the leader of the international [***] movement, and made a lightning strike on Outer Mongolia, occupying the 'Mongolian People's Republic' that had been under the wing of the Soviet Union since 1924 in just one day. The Chinese political axe said to the outside world that this was an action by the Chinese People's Liberation Army to perform normal defense tasks in the Outer Mongolia region at the request of the people of Outer Mongolia to return to China for the provisional political axe. China's action completely crushed the Soviet Union's attempt to turn Mongolia into one of its 16 republics.

Frankly speaking, until the 20s of the 20th century, Outer Mongolia was part of the territory of China. However, as early as the 18th century, Tsarist Russia had territorial ambitions for Outer Mongolia and coveted this sparsely populated, rich in natural resources, and strategically important land of more than 1.5 million square kilometers. The official Russian press has openly claimed that Russia has a special mission in Outer Mongolia and that the Gobi Desert is the natural border of the Far East and South-East of the empire. However, at that time, the focus of Tsarist Russia's aggression was to swallow the whole of Manchuria, and the invasion of Outer Mongolia was still on the back burner. After the Opium War in 1840, and especially in 1860, when the Qing Dynasty was defeated by the British and French forces, Tsarist Russia took the opportunity to force the Qing court to conclude many unequal treaties, seizing large tracts of territory from China and seizing many privileges in Mongolia. After the founding of the Soviet Union, it continued the policy of aggression and expansion of Tsarist Russia, and under the banner of "internationalism", began to carry out new expansion actions against Outer Mongolia, and they realized the dream that the Tsar did not realize.

In May 1924, with the support of the Soviet Union, Outer Mongolia unilaterally announced the establishment of the Mongolian People's Republic, and since then, under the coercion of the Soviets, Outer Mongolia has announced its closure to the outside world and cut off all contacts with China

In the face of China, a rising and aggressive little brother, how will the Soviet Union, the [***] boss, respond? The whole world is waiting to see"

The Times, the most important newspaper in Britain, commented on China's action to recover Outer Mongolia under the title of "How the World Will Face Vengeful China": "After China [***] seized the national power in China, it did not talk about the inheritance of a country's power at all, and they unreasonably described a series of foreign treaties signed by successive regimes before this as 'unequal treaties' imposed on them and overthrew them. It is indeed a regrettable event that they launched an armed invasion of the Mongolian People's Republic, with which they have official diplomatic relations, and arrested the Prime Minister of the Mongolian People's Republic Zedenbar, who was on his way to attend the World Expo, in complete disregard of the most important principle of acknowledging reality and proceeding from reality in international politics, especially in diplomatic relations. China's actions also go completely beyond what the so-called principles of proletarian internationalism allow. To our surprise, this time China has shot the arrow of revenge at its brother socialist countries and their big brother, Russia. Can the Russian boss of the camp teach this feathered brother China, who is always peeking at his position as the Hungarian class? I dare to conclude that there will inevitably be a dog-eat-dog fight between China and Russia, these two [***] powers."

It is not difficult to discern from this review in The Times the bitter wail and gloating meanness of a declining empire.

The Soviet Pravda also published a commentator's article on this: "On May 13, China brazenly launched armed aggression against the fraternal Mongolian People's Republic, which cannot but make us wonder whether the People's Republic of China is still a socialist country. The Mongolian People's Republic was established in 1924 and its international status was established after the end of the Second World War. In February 1945, the United States, the United Kingdom, and the Soviet Union reached the Yalta Agreement, and the first article of the agreement clearly stated that "the status quo in Outer Mongolia must be maintained," and that the Chinese government at that time also recognized the reading power of Outer Mongolia. In October 1945, the then Republic of China sent Vice Minister of the Interior Lei Fazhang to Outer Mongolia to supervise the voting of the all-Mongolian people's referendum. 494074 citizens who voted parted, 489291 voted in favor of reading, and the rest abstained. In other words, 99% of Outer Mongolian voters are in favor of reading. Finally, on January 5, 1946, the Republic of China issued an official proclamation, announcing the establishment of the foreign [***].

On October 1, 1949, the People's Republic of China was founded. Following the Soviet Union, the Mongolian People's Republic established formal diplomatic relations with the People's Republic of China on October 16, 1949. Even in the early 1950s, when China and the Soviet Union negotiated and signed the "Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance," China also acquiesced in the status of the Mongolian People's Republic. Although the Outer Mongolia issue is a matter between the Mongolian People's Republic and the People's Republic of China, and we are only a third party, as a big socialist country and a socialist country that bears great responsibility for the international movement, we cannot ignore this kind of blatant aggression by one socialist country against another socialist country. Safeguard the harmony and unity of the big socialist family and jointly resist the aggression and expansion of the imperialist camp led by the United States"

The Soviet Union was really slow to react to China's lightning takeover of Outer Mongolia.

The Soviet Army's belief in the theory of mechanized offensive operations of large corps with great depth, high speed, and wide front is based on all-out war, and therefore it is only suitable for all-out war and nuclear war, and it is very incompatible with the controllable regional conflict operations that have repeatedly broken out after World War II. Due to the shortcomings of the Soviet army's tactical theory of dealing with local campaigns, the Soviet army was more like a huge but inflexible giant, somewhat overwhelmed in the face of China's operation to recover Outer Mongolia.

After Stalin's death, the defense and armed forces of the USSR were led by the USSR [***], the Congress of People's Deputies of the USSR, the Supreme Soviet of the USSR, the Council of Defense of the USSR and the Council of Ministers of the USSR. The National Defense Conference of the Soviet Union is the supreme national defense organ with special and full powers, and exercises unified leadership over the defense of the Soviet Union, the party, the government, and the military. The chairman of the National Defense Council was the ex officio Supreme Commander-in-Chief of the Soviet Armed Forces, held by the General Secretary of the Central Committee of the CPSU.

At this time, the General Secretary of the Central Committee of the CPSU Nikita Khrushchev was really a little confused. What should I do about this? A full-scale war with China? The People's Congress of the Soviet Union is the highest organ of power in the Soviet Union, and only the People's Congress can decide on such important issues as war and peace. It's just that you can have the final say, can you fight this battle? In Europe, the North Atlantic Treaty Organization, which is eyed by the imperialist camp led by the United States, and in Asia, it is faced with China, a socialist country that does not take itself seriously at all. If it weren't for China's persuasion work among these little brothers, I am afraid that the Warsaw Pact of the socialist camp would really be in chaos, and without the Warsaw Pact, the Soviet Union would lose its geostrategic advantage in Europe, and it would be difficult to guarantee the security of the Soviet Union itself. And the Molotov gang of bastards in the party actually took advantage of the chaos of the international communist movement to overthrow themselves. These intricate factors at home and abroad, inside and outside the party, are intertwined, interconnected, and interact, and really affect the whole body, and any mistake on your part will put you in a situation from which you will never recover.
