Due to the absence of the Trans-Siberian Railway, although the Tsarist Empire occupied the vast Siberia, it actually did not have many defense forces, but only established hundreds of strongholds to fight against the indigenous Tungusic and Nenets in Siberia and stabilize its rule.

The number of Tsarist troops in each stronghold was different, with the largest numbering tens of thousands, and the smallest even a few dozen.

The Ming army said that it was divided into 24 roads, 5,000 iron cavalry on each road, but in fact, after the 5,000 Ming army iron cavalry on each road really entered Tsarist Russia, they were divided into multiple roads, and in general, the Ming army's 100,000 regular army iron cavalry was at least divided into 100 roads.

Although Tsarist Russia was respected by Moscow and the Tsar, it was in fact a federal empire.

Many of the distant territories that had been developed were too far from Moscow for the Tsar to rule personally, and were given autonomy to the corresponding governors, which gave the Russian Empire a large number of autonomous regions and principalities.

For example, the area directly north of the Trans-Khingan Mountains is the Sakha Principality and the Khabarovsk Principality of the Tsarist Empire, and after the two principalities were divided, a total of hundreds of strongholds were established in the country.

Taking the Seventh Army as an example, after leaving the Khingan Mountains, the Seventh Army continued to attack northward, facing the two autonomous principalities of Tsarist Russia, Sakha and Khabarovsk.

The Seventh Army of 20,000 people, although it was only divided into four roads at the beginning, but it destroyed a number of Tsarist strongholds in a row, captured many Tsarist generals, thoroughly understood the specific situation of the two principalities, and knew that there were not too many Tsarist soldiers in each stronghold, and the combat effectiveness of Tsarist Russian soldiers was too weak compared to the Ming army, in order to achieve decisive results faster, the Seventh Army soon immediately divided into twenty roads from four roads, and each road only had the appearance of a thousand Ming cavalry.

Don't look at the Seventh Army, there are only a thousand cavalry on each road, but the combat effectiveness of these 1,000 Ming cavalry can be completely broken even if it attacks the Tsarist stronghold of tens of thousands of people, and each cavalry is not far apart, and they are all related to each other.

Chang Shunhou, the commander of the Seventh Army, personally led the cavalry of the Seventh Army with 1,000 men all the way through the snow.

The further north you go, the deeper the snow gets, and if it weren't for the need to consign military supplies, it would have been faster to enter Siberia than by sled. No, the spies sent out by the Ming army and the people who were in contact with each other were actually moving forward with sleds.

The Ming army led by Chang Shunhou had just broken through a 200-strong Russian stronghold.

The city of Yakutsk, the main seat of the Principality of Sakha, was founded about a thousand miles north of the Trans-Khingan Mountains.

About ten soldiers of the 7th Army were probing about a few dozen miles from the city of Yakutsk.

The closer you get to the core of the Sakha principality of Tsarist Russia, the more and more strongholds of the Tsarist Russian army become, and of course, there are also Russian soldiers who come out to patrol.

Like the Ming army spies, most of the Tsarist soldiers who came out to patrol were also on sleds, and the Ming army spies were obviously easy to collide with them.

"Whew! "No, a team of dozens of Tsarist Russian soldiers chased after ten Ming spies, shooting arrows or shooting at Ming spies from time to time.

It's just that the range of the bows and muskets of the Russian soldiers is not far, and it is difficult to shoot the fleeing Ming spies.

said that he was fleeing, but in fact, it was just to distance himself in the escape, and kill the pursuing Russian soldiers one by one.

While a Ming soldier was sliding forward in the snow, he suddenly raised his rifle and aimed backwards, and pulled the trigger to shoot past.

"Bang!" A shot passed, and a Russian soldier who was pursuing behind him fell into the snow.

"Bang! Bang! From time to time, other Ming soldiers also aimed and fired at the back.

One after another, the Russian soldiers fell into the snow during the pursuit, and the pursuing Russian soldiers became fewer and fewer, and by the time this point came, there were less than ten Russian soldiers left in pursuit.

"God! How come there are only a few of us left! A Russian soldier's eyes widened in horror and he exclaimed.

Several other Russian soldiers also looked to the left, right, and back, their eyes widening as well.

"Quick, get back to camp!" There were frightened shouts of Tsarist soldiers.

Immediately, less than ten Russian soldiers began to hurriedly stop sliding and prepare to turn back to the camp, the enemy they were pursuing was so terrifying that they didn't know what kind of weapons they were holding, and they could shoot their people from a distance of several hundred meters, such an enemy was not something they could pursue.

"Captain, there are a few Russian soldiers left who want to run!" The ten Ming army spies also stopped, and one of them said.

"Run? Did they run away! The captain of the scout said disdainfully.

"Now it's our turn to hunt them down and finish them all!" The captain ordered.

Immediately, while the remaining Russian soldiers turned from pursuing to fleeing, the ten Ming spies also reversed from fleeing to pursuing.

It was obviously better to shoot when pursuing than when fleeing, so the reversal became a tragedy for several Tsarist soldiers who fled.

Facing the muzzle of the Ming army spies, several fleeing Tsarist Russian soldiers were terrified, and they wished that they could speed up and speed up, but unfortunately no matter how fast they were, they could not be faster than the bullets.

"Bang! Bang"

yes

After a while, five Russian soldiers were shot and killed, and only four Russian soldiers were still running for their lives.

"Poof!" Another Tsarist soldier was shot and killed, and his body tumbled into the snow.

The last three remaining Russian soldiers collapsed at once, threw away their weapons one by one, stopped running away, and knelt in the snow in fear to surrender.

Soon, Ming spies surrounded and captured several Russian soldiers.

"Go back and report to the army commander quickly, there are three Tsarist strongholds ahead!" The captain said to two of the Ming army spies.

"Yes, Captain!" Immediately, the two Ming army spies slid away to report to the large army what they had just discovered.

After receiving the news from the spies, Chang Shunhou did not hesitate, and immediately rushed to the three Tsarist strongholds with a thousand Ming soldiers along the way.

Although it was already very close to the core stronghold of the Sakha Principality of the Tsarist Empire, the combined number of Tsarist Russian soldiers in the three strongholds was less than 2,000, and a thousand Ming troops were completely able to break through.

About half an hour later, the three strongholds were attacked by Ming soldiers at the same time.

"Da Da Da"

"Boom! Rumble! "Machine guns and a few cannons were aimed at the Russian soldiers in the stronghold, and they were strafing and bombing together.

"Bang! Bang! "The Ming soldiers opened fire while constantly attacking forward.

Although more than half of the Russian soldiers in the stronghold had muskets, they were all extremely rough muskets, compared with the rifled rifles of the Ming army, not only had a short range, but also had a very low power, and in the face of the attack of the Ming army, there was not much power to fight back.

In less than half a pillar of incense, Ming soldiers stepped into the stronghold.

"Boom!" The grenade was thrown into the snow pit where the Russian soldiers were hiding, and at once the three Russian soldiers inside were blown away.

In the face of such a fierce attack by the Ming army, the Russian soldiers in the stronghold soon began to retreat.

It took only about a stick of incense for the Ming army to break through the Tsarist army in the three strongholds, and the army continued to march towards the city of Yakutsk.

Also because of the closer and closer to the city of Yakutsk, the other 9th Route Army of the Seventh Army also slowly regrouped together, preparing to encircle the city of Yakutsk together, completely solve the main core stronghold of the Principality of Sakha, and capture the Principality of Sakha.
