Irkutsk, the second largest city in Eastern Siberia. It is known as the "heart of Siberia". It's just that now Irkutsk has turned into a huge military camp. 200,000 Russian troops are stationed here, and there is a steady stream of Russian troops arriving in Irkutsk by guò trains, constantly strengthening the strength here.

After the arrival of Grand Duke Nikolai in Irkutsk, he had already taken over the command of the whole of Eastern Siberia. Even the Governor of Eastern Siberia, Anuchin, became an assistant to Grand Duke Nicholas, and was responsible for providing logistical support for the Russian army.

Inside the headquarters of the Russian army, Nikolai frowned, staring at the large map of East Siberia hanging on the wall. The news of the attack of the squadron did not surprise Grand Duke Nikolai. During this period of time, the frequent movements of the squadron on the front line had attracted his attention, and he had already expected that the squadron would attack in the near future. Therefore, he also sent a telegram to Lieutenant General Vladimir, who was stationed in Ulan-Ude, asking him to take good defense. It's just that I don't know if the Kyakhta front can withstand the attack of the squadron. Lieutenant General Vladimir deployed a hundred thousand troops in Kyakhta, which Grand Duke Nikolai knew. It's just that he doesn't know that Lieutenant General Vladimir is deployed in Kyakhta with some garbage troops. When he came, although the attack of the squadron was fierce, with the military strength of Kyakhta, it should be no problem to resist the attack of the squadron for a few days. And these few days are enough for the Russian army to make the correct deployment.

"Humph! These yellow-skinned monkeys, if they want to preemptively spread the flames of war to the territory of Russia, then I will fight a general battle with them in Ulan-Ude as they wish! How can those weak yellow-skinned monkeys be the opponents of the great Russian soldiers, I am going to teach them a hard lesson in Ulan-Ude! Grand Duke Nikolai thought secretly.

"Command! 62nd Infantry Division, 65th Infantry Division, 66th Infantry Division, 69th Infantry Division and 70th Infantry Division. As well as the 2nd Cossack Regiment and the 5th Cossack Regiment, immediately reinforced Ulan-Ude, ready to fight a decisive battle with the Chinese in Ulan-Ude! "Grand Duke Nikolai ordered. Five infantry divisions, plus two Cossack regiments, totaled nearly 100,000 troops, which was already the largest force he could take. With these forces deployed, Irkutsk's defenses will be slightly weaker. However, fortunately, the number of Russian troops is increasing every moment, and the longer the battle of Ulan-Ude is fought, the more troops the Russian army will mobilize to Irkutsk.

"Yes, Your Excellency!" After the adjutant took note of the order, he immediately prepared to give an order to the Russian troops stationed around Irkutsk. The military situation is like fire, but it cannot be delayed for a moment.

"Wait a minute, casually send a telegram to His Majesty the Tsar, asking him to speed up his support for the Eastern Siberian theater of operations. We are facing the attack of hundreds of thousands of elite squadrons, and the strength is not enough! Grand Duke Nikolai said. In previous battles, the Russian army generally fought more and fought less, so as to ensure victory. Now in the face of the attack of the squadron, the Russian army does not have an advantage in terms of strength, and at the same time it is still at a disadvantage in terms of weapons and equipment, so it is difficult for him to achieve the final victory.

"Yes, Your Excellency!" The adjutant took the order. Russia has a population of 130 million, and Russians are naturally tall and strong, and their bodies are very good enough to serve as soldiers. If the tsar had been willing, and Russia had enough money, Russia could have armed tens of millions of troops. This is why Russia is weak in industry, but it has been able to become one of the great powers in Europe. Although the population of China is about four times that of Russia. But to the Russians, the weak body and thin physique of the Chinese are all disabled people, and they are not qualified soldiers at all, and they cannot be compared with the Russian army.

About an hour later, Grand Duke Nicholas's lieutenant entered the command again, but his face was a little anxious.

"Your Excellency, Major Turgenev from Kyakhta called, the attack of the squadron is very fierce, and they can't resist it!" The adjutant said. Less than half a day after the battle began, he received such a telegram, which made him a little incredulous.

"What? How so? Grand Duke Nikolai was shocked. An army of 100,000 can't hold out even for a day?

"Your Excellency, the defenders of Kyakhta, with the exception of Major General Turgenev's 6th Cossack Cavalry Division, the rest of the troops are newly formed units. Elite troops, already left in Ulan-Ude by Lieutenant General Vladimir! The adjutant explained.

"Damn! Did Vladimir get kicked in the head by a donkey? Isn't it for a group of recruits to guard Kyakhta? Immediately send a telegram to Vladimir and ask him to send powerful troops to Kyakhta, no matter what, to resist the attack of the Chinese! Grand Duke Nikolai ordered angrily. He has just begun to transfer troops, and if Kyakhta is breached, then the reinforcements he sent will not reach Ulan-Ude in any case. Without Ulan-Ude, Irkutsk will have to face the front of the squadron. To make matters worse, Russia will lose its ties with the Far East east of Lake Baikal.

"Yes, Your Excellency. However, Lieutenant General Vladimir had previously called that he had already sent a Cossack regiment to Kyakhta. Hopefully, they will be able to repel the attack of the squadron. In addition, Major General Turgenev meant that he wanted the defenders of Kyakhta to retreat north, so as not to be surrounded by the squadron! The adjutant said.

At this moment, another staff officer walked in and handed a telegram to the adjutant of the Grand Duke Nicholas. After the adjutant finished, his face suddenly changed greatly. It seems to have been shocked by what was on Telegram.

"What's wrong?" Grand Duke Nikolai asked with a frown.

"Your Excellency, the Chinese cavalry appeared north of Kyakhta, cutting off Kyakhta and Ulan-Ude. The defenders of Kyakhta, already surrounded! The adjutant said.

"What? How can the Chinese move so fast? Directly give orders to Major General Turgenev, asking him to prepare to defeat the Chinese cavalry and reopen the connection with Ulan-Ude. If, if it really doesn't work, retreat to Ulan-Ude! Grand Duke Nikolai said with a dark face. After Kyakhta was breached, the squadron general was under the city of Ulan-Ude, and his goal of fighting a battle with the squadron in Ulan-Ude could not be achieved. Moreover, the entire defenders of Ulan-Ude may be annihilated, which makes him very angry.

"Yes, Your Excellency!" The adjutant hurried to send a telegram.

The Chinese cavalry that appeared north of Kyakhta was the unit of the Ninth Brigade of the Third Cavalry Army, and they took the lead in setting off, running for dozens of kilometers, making a detour to the north of Kyakhta. Behind them was the main force of the 3rd Cavalry Army. With a single charge, the 9th Cavalry Brigade annihilated the forces of a battalion deployed by Turgenev north of Kyakhta, besieging Kyakhta from the north.

Now Kyakhta is already in a mess. As the Chinese cavalry appeared in the north of Kyakhta, the Chinese cavalry and infantry also appeared in the west, and in the east, tens of thousands of squadrons were also found to be rapidly moving northward. There is no doubt that the squadron wants to eat all the 100,000 Russian troops in Kyakhta in one fell swoop.

"Turgenev, you can't hesitate any longer, the Chinese want to eat us all, and if you don't leave, I'm afraid it'll be too late!" Major General Mikhael said anxiously.

Not receiving an order, Major General Turgenev was still a little hesitant. Fortunately, they did not wait long for the order of Grand Duke Nicholas to be given.

"Order the 6th Cossack Cavalry Division to get ready, and in twenty minutes launch an attack on the Chinese cavalry, so that they can see what a real cavalry is!" Immediately after receiving the order of Grand Duke Nikolai, Major General Turgenev made a deployment and prepared to send his Cossack cavalry division to open the way for the Russian troops stationed in Kyakhta to withdraw north.

The Cossacks were a nomadic community living in the steppes of Eastern Europe (Ukraine, southern Russia). Historically known for its prowess and horsemanship, it was the main force that supported the expansion of the Russian Empire eastward in the 7th century.

At the beginning of the century, a number of Slavs fled the rule of the Kipchak Khanate in the Mongol Empire to southern Russia, including the Don River valley, the lower Dnieper River and the Volga River basin. In the 5th and 6th centuries, some Russian and Ukrainian peasants who did not want to become serfs migrated to southern Russia after the overthrow of the Kipchak Khanate. These people were called "Cossacks", that is, "free people" in Turkic. The Cossacks established a number of local regimes in Ongo. The Eastern European Plain is mountainous and less mountainous, so most of the Cossack ethnic groups are named after rivers, such as the "Don Cossacks".

The Cossacks were known for their bravery and good fighting. In Russian history, the Tsar bought the Cossack elite and controlled the Cossacks. The cavalry, composed of Cossacks, was an important force of Tsarist Russia. During Russia's expansion into Siberia, the Cossacks were Russia's main dependents.

In the era of cold weapons, the Cossack cavalry shocked Europe with its speed, mobility, lethality, and brave warfare, and European countries often recruited Cossacks as mercenaries. The Cossacks took part in all the battles from the century to the Soviet Union in World War II. Some say that they are the most reckless classic cavalry in the Eurasian steppe. Their cavalry hooves flew in tandem with the pace of Tsarist Russia's outward expansion, and they made great achievements in Russia's territorial expansion on many occasions.

During the Soviet-Polish War in later generations, the American pilots who had overlooked this unit from the air had this description: "The cavalry is eight people and eight horsemen in each row, some wear cylindrical curly hats, some wear black coats, they carry rifles on their backs, and their sabers hang from their waists, and they march mightily in the dust, tens of thousands of horses gallop across the country, and tens of thousands of swords are staggered, this scene is extremely shocking, and it has become the most magnificent scene in the history of cavalry warfare." ”
