Although Kulen is said to be the "capital" of the Republic of Mongolia and the largest city in Outer Mongolia, it is actually equivalent to a slightly larger county town in Chinese mainland, not to mention the small city, the permanent population is also pitiful, and more importantly, it has not experienced war for a long time, so things like city defense facilities are not worth mentioning at all.

In addition, the Republic of Mongolia has only been established for more than a decade, and it has always been under the protection of the wings of the Soviet Union, and its own defense capability is very weak. In addition, the population of the whole country is only more than 1.5 million, so the total strength of the whole country is only more than 100,000, and it is mainly cavalry, organized into 2 infantry divisions and 9 cavalry divisions, in addition to an artillery brigade and 1 tank regiment.

The Mongolian army was annihilated by two cavalry divisions at one time in the second company battle, and now there are less than 100,000 troops left in the country, and although the Soviet Union has a lot of garrisons in Outer Mongolia, it is difficult to gather them in a short period of time, so after the plan for entering Kulen was formulated, Chen Feng and Yang Yi and others have always believed that there was almost no battle along the way in this northward operation, and the big war should break out near Kulen. A quick decision is the most suitable for the Eighth Theater.

Therefore, Chen Feng decided to send a force that was not too large in number but had extremely strong comprehensive offensive capability to take on the task of going north this time.

On the afternoon of 3 June, the former enemy command issued an order that the Eighth Theater Guard Division would become the main force in this operation, but the troop establishment was simply adjusted, and the adjusted guard division had two mechanized infantry brigades, one armored brigade, one army aviation brigade, one air defense brigade, one logistics baggage brigade, one heavy artillery regiment, and one special operations brigade. The total strength is more than 28,000 people.

According to the operational plan formulated before the war, the guard division was the main force in the northward operation, and it mainly attacked north along the railway line. At the same time, the 101st Division followed suit, halting its advance in a small county town 400 kilometers deep into the territory of the Republic of Mongolia, and then building an airstrip there to provide a springboard for the large combat fleet of the Northern Air Force.

At 3 p.m. on 3 June, the whole guard division pedaled north, heading toward Kulun, the capital of Mongolia.

A division under Chen Feng's department suddenly went deep alone, which made the high-level leaders of the Soviet Union and Mongolia extremely puzzled, what does it mean that only one division went north? Could it be that the Chinese general was planning to use this division to defeat the combined forces of the Soviet Union and Mongolia?

But the idea was quickly rejected by them. Even China. No matter how powerful the army is. It's just the strength of a division. Although the two countries have not yet completed the transfer of troops, the Soviet-Mongolian forces hoarded on the extreme periphery of Kulen have exceeded 80,000 people, including two tank divisions and two artillery brigades. No more troops are needed, the army near Kulen alone is enough to take out this infantry division of the Chinese.

What happened next, however, was far beyond their expectations. The Chinese infantry division did just swagger north. The whole army advanced along the railway line. There were more than thirty military trains accompanying it. The army set out from the second company and arrived at Zamyn-Uud, the first city in Monam, in the afternoon of the same day.

Originally, there were not many Mongolian troops stationed in Zamyn-Uud, because it was a border city. It is also the only way to China, so the permanent strength here is a cavalry regiment, with a total strength of more than 1,200 people, plus the security police and other armed forces in the city, the total strength has reached more than 1,500 people.

However, due to the great rout of the Soviet-Mongolian coalition some time ago, although the vast majority of the Soviet-Mongolian army was annihilated by Chen Feng's department, there are still a small number of fish that escaped here, according to the data reported by the top administrator of Zamyn-Uud Bayinbaoli to the Mongolian high-level, as of noon on June 3, the total number of Zamyn-Uud defenders plus the rout that was collected has exceeded 3,600 people.

Chairman of the Council of Ministers of Mongolia and Commander-in-Chief of the People's Army, Khorlo? Choibalshan instructed Bayinbaoli and ordered him to immediately arm all the routed troops, whether they were Soviet or Mongolian, into the combat formation of the Zamyn-Uud garrison, and at the same time upgrade the Zamyn-Uud garrison to a brigade.

When he learned that a division of Chen Feng's division had gone north to attack Zamyn-Uud, Bayinbaoli was shocked, and he knew that with the little force in his hands, he could not fight a field battle with Chen Feng's department at all, and could only rely on Zamyn-Uud's city fortifications to resist. Although in his opinion this was also an extremely stupid decision, after all, Zamyn-Uud was only a small city, although it had walls, but it was less than three meters high and less than two meters wide, and it was a very old earthen wall, which could not withstand a few cannons at all.

But Choibalsan ordered him to stay where he was for a day and a night, when reinforcements would come south to reinforce them. At the same time, one more day of their delay here will buy one more day for the Soviet Union and Mongolia, and when the heavy army group from the Soviet Far East arrives, then it will be time for them to counterattack the northern province of Cyprus.

In the view of Choibalshan and others, although the defenders in Zamyn-Uud are far less than the Chinese troops, they are better at fighting on the mainland, and the soldiers' will to resist is relatively tenacious, and the terrain of Zamyn-Uud is relatively high, Chen Feng's attack is very laborious, which can be regarded as easy to defend and difficult to attack, and the nearest Saishanda to Zamyn-Uud is a cavalry brigade stationed in the Mongolian army, as long as Bayinsu can't hold out for a day, this cavalry brigade can arrive.

And Ulaanbaatar (Kulen) is not very far from Zamyn-Uud, if it is a train march, it will take two and a half days at most to reach Zamyn-Uud, as long as the advance of the Chinese army is blocked in Zamyn-Uud, and the rest will be left to the follow-up army.

After Chen Feng's troops arrived at Zamyn-Uud, when Bayin and others thought that a bitter battle could not be avoided, about 100 soldiers stationed at the south gate mutinied, killed Major Luo Mande, who was in charge of the south gate, and then opened the city gate and let Chen Feng's troops in, and in the face of absolute strength, nearly 4,000 Mongolian troops only lasted less than an hour before they were all annihilated.

When the news reached Ulaanbaatar, Choibalshan and others were shocked that the Mongolian army would mutini on the battlefield, and also killed the commander of the Soviet army on the front line, and let Chen Feng's troops in, which was a serious problem. This is not just a matter of surrendering to the enemy, but it is also a big challenge for Soviet-Mongolian relations.

After all, no matter in terms of geographical relations or ethnic structure, Mongolia is still closer to China, and the main ethnic group of Mongolia is Mongolian, and more than ten years ago they were still members of the same country, even now they still worship an ancestor. It had nothing to do with the Slavic nation of the Soviet Union, and if it were not for the coercion and temptation of Tsarist Russia, Outer Mongolia would not have been able to secede from China.

And whether it is Choibalsan or the Soviet government, it is also clear that not everyone agrees with the Mongolian government at this time, if it were not for the perennial Soviet army stationed here, forcing those who oppose it to have to deal with it carefully, and China is now suffering from the most serious national crisis in thousands of years, it is not the best time to return to China at all, so those people will be a little more restrained.

But now with the war between Chen Feng's troops and the Soviet Union, I am afraid that those people will not miss this opportunity, and maybe those soldiers are caused by those opponents. More than 100 soldiers mutinied in just one Zamyn-Uud, and how many opponents did the entire Mongolian army of more than 100,000 people have? In addition, the victim this time was not only an officer, but also a Soviet officer, and the chain reaction triggered was not the slightest bit, so Choibalshan immediately telegraphed to Stalin, hoping to personally talk to General Zhukov, the former commander-in-chief of the Soviet army.

However, even Choibalshan and Stalin did not expect that in fact, this matter was a misunderstanding from beginning to end, and those soldiers had nothing to do with the so-called opposition, and those soldiers were Chinese at all, Mongolian special forces under Chen Feng.

When the Soviet-Mongolian coalition army was defeated, Chen Feng sent a special operations squadron to blend in with the rout of the Mongolian army, their intention was to find the senior officers of the Soviet-Mongolian army who were lone or retreated, and at the same time spy on the enemy, but they did not expect to enter Zamyn-Uud directly.

It is also to blame that the Soviet-Mongolian coalition forces have no combat experience, and it is extremely important to screen enemies and enemies on the battlefield, and even to dig up hidden traitors from within themselves, for example, the Eighth Theater has a special internal security department to deal with these things. However, the Soviet-Mongolian coalition has always had Japan as its main opponent. The Japanese are still very easy to recognize, after all, the height of one meter six or five and the disgusting Rendan beard are the most obvious features, and the Japanese do not wear underwear, only those things like diapers, and they really can't identify them and take off their pants, whether the Japanese can see it at a glance.

But the Chinese are different, especially those Mongolian men of Chinese origin, who are originally of the same ethnic group as those defectors and separatists in Outer Mongolia, and there is not much difference in appearance, language and living habits. Not to mention that they didn't even think of meeting China . The army fights, and it has no experience in dealing with spies who wear the same military uniform and speak the same language, and it is difficult to distinguish even if they are prepared.

In addition, the special forces are a new branch of the armed forces, whether it is Germany, Japan or the Soviet Union, they are still being tested, and their understanding of this new type of armed forces is very limited. The Japanese are okay, after all, they have suffered so many losses, and now they will first guard against the sneak attack and infiltration of the Chinese special forces as soon as they start a war.

However, the Soviet Union and the Outer Mongolian army were different, the first time they fought with Chen Feng's troops, they didn't know that there was still such a force in China, and they didn't have the opportunity and experience to fight with this force, so they were easily exploited by the special combat team, and Chen Feng's troops easily captured Zamyn-Uud, and also created a little shadow on the relations between the Soviet Union and Mongolia.
