After a few days of blocking, Zhou Yaoming and the generals of his 48th Army gradually built up their confidence in fighting the Soviet army and fought more orderly.

The time for each interdiction of the two brigades was also gradually increasing. Before retreating to the blocking position of the 138th Division of the 48th Army, a brigade had been able to take advantage of the favorable terrain to stubbornly hold back the Soviet troops for three days.

Although the casualties were still very large, the defense was already calmly organized. After a few days, the Soviet casualties began to gradually increase, and the vanguard division of the Soviet army, which had seized the exit of the river valley, had no choice but to withdraw to rest.

In order to delay the Soviet offensive as much as possible, Chu Xichun ordered Zhou Yaoming to send a special brigade directly under the army to go deep behind enemy lines, using squadrons and squads as a formation to attack and harass the Soviet army day and night.

These harassing units often ambushed small groups of Soviet search forces during the day. Often, as soon as the Soviet search unit has finished searching a certain area, the transport unit is attacked suddenly and violently, killing and wounding people and burning supplies. As a result, the Soviets had to send heavy troops to protect their baggage transport units, which were also plagued by landmines.

Although the heavily protected transport units were attacked less often, the Soviet army's supply rate slowed down significantly. Seriously slowed down the pace of the offensive of the main forces of the Soviet army.

And that's not even counting the fact that at night, the personnel of the special brigade will be more active. Not only will the sentries of the Soviet army often be killed and wounded by cold guns, but the Soviet troops sitting around the bonfire for warmth will often be attacked by mortars, and these attacks will never stop until dawn, and many officers and soldiers of the Soviet army who have been tossing all night are like pandas the next day, not to mention fighting, even marching problems. In the end, the Soviets had no choice but to send small units of companies and platoons to go out on a large area at night to guard from afar.

Although the Soviets allowed the large troops to rest safely and ensure that they had the physical strength and energy to fight the next day, the losses of the troops not only did not decrease, but on the contrary increased.

This is because the special forces failed to harass the main forces of the Soviet army, and instead began to attack these small units on alert. Night battles are their forte, and they are even more comfortable attacking small Soviet units at night. Sometimes, the Soviets lost one or two platoons in one night.

The Soviets also sent troops to pursue the special forces that attacked them, but with little success and heavy losses.

The members of the special brigade are very well adapted to mountain warfare, and even if they are not members of the original Taiyuan Special Operations Brigade, but new members of the special forces transferred from various armies, they have all undergone a certain degree of special training, and they are like fish in water in the mountains and woods, and they are comfortable with the Soviet army.

In particular, these people not only have very accurate marksmanship, but also are extremely good at fighting, and they have a clear advantage in hand-to-hand combat with tall Soviet troops in the dense forest. Often, hundreds of Soviet troops pursued the members of the special brigade with only a squad of more than 30 people, and after several rounds of fighting, the Soviet troops lost their troops and withdrew to the ground.

In the mountains, taking advantage of the favorable terrain, a brigade can fight hard with a division of the Soviet army for two to three days!

This news made Song Zhewu, who was far away in Taiyuan, let go of his hanging heart, and finally secretly breathed a sigh of relief in his heart.

Because Song Zhewu had memories of World War II in his previous life, he was very afraid of the powerful Soviet Red Army, and before the war, he was very worried that his troops would not be able to fight the Soviet army on the frontal battlefield. But after receiving the reports from Li Wentian and Chu Xichun, he was no longer worried. Since the field battle can withstand the attack of the Soviet army, Kulun, who has a strong fortification group, will be able to block the Soviet army even more, as long as Kulen does not lose, he is confident that he will thwart the Soviet invasion of Northern Mongolia and achieve victory against the Soviet army.

Of course, this victory must be built on the basis of huge casualties, and Song Zhewu was mentally prepared for this.

Judging from the combat situation on the Eastern Front in the past few days, the casualties of the Soviet Army and the Fourth Route Army are about a little more than two. Ninety percent of the casualties of the Fourth Route Army were caused by the intense artillery fire of the Soviet troops and the bombardment of large groups of aircraft.

What made Song Zhewu feel very strange was that the weapons and technical weapons of the Soviet army should be said to have been basically modernized, at least in the army. Moreover, many of the generals of the Soviet Army had a unique strategic vision and campaign command ability, and some of them could even be said to be of a world-class standard. However, for some reason, the tactical level of the infantry of the Soviet army has always lagged behind.

For example, when the Soviets attacked, they paid special attention to the skirmish line attack, and the soldiers rushed forward with their mosin Nagant rifles and rifles with bayonets on them. For such tactics, it was easy to thwart the Soviet offensive as long as the defending side still had enough firepower after the Soviet artillery bombardment.

Compared with the offensive on the middle and east roads, the Soviet troops on the west road made the most smooth progress, they did not go through any battles, and they did not even see the central [***] team, and on the day after the start of the offensive, they occupied Mulun, an important town in the western part of Northern Mongolia. Of course, Mulun is also an empty city.

Mulun, in the strict sense of the word, could not be called a city, because not only did it have no walls, but even there were almost no brick and wood houses, and only one lama temple was made of brick and wood. However, there were no lamas in the temple for a long time, and during the Choibalsan period, the lamas were forced to return to the laity or flee to Xinjiang Province and Qinghai.

The inhabitants of the Mulun region are mainly Mongolians and Kazakhs, and although there are only a few thousand Mongolians, there are more than 20,000 Kazakhs. The people here live in wooden tents in the form of wall trusses, and the inhabitants have largely abandoned their nomadic life in favor of farming.

In order to clear the wilderness, the residents here were urgently relocated to Uriya Sutai, hundreds of kilometers southwest of Mulun. It is not possible to mobilize the inhabitants of the region to move with the axe of the Northern Mongolian Autonomous Government alone, and these Kazakhs are not only very strong, but also have their own organization, and their head is called Gani. Kasimov.

Ghani. Kasimov was the youngest son of a dignitary in the Kazakh Khanate, and graduated from St. Petersburg University in Tsarist Russia at an early age. He actively participated in the founding of the Arash Autonomous Republic in 1917 and served as the Minister of Political Axe in the founding of the Alash Autonomous Republic, and had close relations with Belarus. In 21, the Autonomous Republic of Arash was forcibly dissolved by the Soviet political axe, and after the territory was incorporated into the Soviet Union, Kasimov led part of the tribe to flee to Mulun.

Since January 30, when the Soviet Union began to enforce collectivization, there was a great famine, and the Soviet government sent a large number of workers' party members to the countryside to collect grain. The hard name stipulates how much grain each family must hand over, and if they can't hand over the food, the team can write a verdict on the spot and pull the whole family out and shoot them......
