Sun Chuanting led an army of 300,000 to build siege equipment and siege the city, and it took a total of fourteen days to take the No. 18 fortress of Tsarist Russia, which was about the same as half a month that Zhu Cijiong had estimated.

In fact, under normal circumstances, it only takes so long for the Ming army to take a fortress, because the Ming army's weapons and equipment are much better than the Russian defenders, and it also occupies an absolute advantage in numbers, unless the enemy has reinforcements, otherwise a fortress will definitely not last for half a month.

The reason why Zhu Cijiong gave Sun Chuanting and Lu Xiangsheng four months to each take four fortresses was because he was afraid that they would encounter Russian reinforcements and delay the time.

This time the enemy did have reinforcements, but Sun Chuanting did almost nothing in defense, and the number of reinforcements in Tsarist Russia was not as many as the men and horses he brought, so Golovin didn't even have the courage to sneak attack, so he could only watch him take down the No. 18 fortress.

After taking the No. 18 Fortress, Sun Chuanting did not immediately march to attack the No. 19 Fort of Tsarist Russia, but stayed where he was, resting while waiting for the vassal army to repair the railway.

The eighteenth fort was only more than 100 miles away from the base camp of the Ming army on the Rem River on the South Road, and if it weren't for the fact that the city of Rem on the north side of the Rem River had not been completed, the vassal army would have repaired the railroad long ago.

However, now that the city of Rem was nearing completion, the vassal legions were able to concentrate their main efforts on the construction of the railway, and the remaining dozens of miles away they were building the railway as fast as they could, and on the third day after the battle, the vassal legions repaired the railway line to the vicinity of Fort 18.

Sun Chuanting still did not set off, but commanded the army of the vassal state to completely repair the No. 18 fortress with cement, and at the same time ordered them to extend a sub-city that could garrison more than 10,000 men and horses along the first floor of the fortress to the railway, and built a small railway station in it.

After four or five days of busy work, the project near the No. 18 fortress was basically completed, and he continued to march with the First Army of the Border Guards, the Second Army of the Border Guards, and the Qin Army.

The No. 19 Fort of Tsarist Russia is also more than 100 miles away from the No. 18 Fort, but the No. 19 Fort is only two floors in total, and the scale is not large, and it can accommodate two or three thousand people at most.

Sun Chuanting knew these things well, and even set up camp in advance, and even had the camp selected in advance, and the army was stationed, rested for the night, and began to manufacture siege equipment the next day.

Anyway, didn't a lot of siege equipment already be made in the eighteenth fort, why didn't they move it over together and rebuild it?

This is mainly because it is too troublesome to carry over, you must know that the turret, siege vehicle and ladder are already heavy, the Ming army also has to carry artillery and grain and grass baggage, all the horses are basically occupied, to move the turret, siege vehicle and ladder, only rely on manpower.

Turrets and siege engines are as heavy as them, and it's okay to push them a mile or two to attack the city, because there is generally flat ground around the city, and even if there is none, it can be filled, and it is not very difficult to push, and if you take the march, it will be troublesome.

There is no road on this wasteland, it is uneven, there is no horse-pulled, and it is simply a human life, and it is good to be able to travel thirty or forty miles a day, and it will also make all the soldiers tired, it is better to save time and effort by building on the spot.

As for the ladders, not to mention, the fortresses of Tsarist Russia cannot all be built as high, and they don't know if they are used to carry them over, and they are also not as good as building them on the spot, but after the successful experience of the last time, Sun Chuanting did not let people build too many ladders, because the tactic of digging the city wall does not need many ladders at all, but the number of siege vehicles can be built a little more.

In another five days, the Ming army prepared all the siege equipment, and the difficulty of conquering the two-layer fortress was at least half that of the three-layer fortress, and if he was in a hurry, Sun Chuanting could even take down the nineteenth fortress in two or three days.

Of course, he was not in a hurry, so he still used the old tactics to dig up slowly, and in six days before and after, there was no accident, and the Ming army on the South Road easily took down the No. 19 fortress.

Isn't it stupid to say that the guards in the fortress are not stupid, 2,000 people still don't run when they see the 300,000 army, and they still have to defend there, do they want to die?

Of course they don't want to seek death, the reason why they don't run is the same as Andrei's, Golovin, who lacks virtue and smokes, he knows that there is little chance of sneaking up on the Ming army, but he wants to send someone to inform the defenders of the fortress that he will lead the army to attack the Ming army and let them resist!

He did this for no other purpose, that is, to let the Ming army slowly gnaw down one by one, consume their troops, consume their ammunition, he thought that the Ming army would continue to attack, such attrition, twenty or thirty times in a row, the Ming army on the south road is estimated to have serious casualties, exhausted, and at that time, he will have a chance to defeat the Ming army on this road.

His idea is not wrong, although every time the Ming army conquers a fortress, there are not too many casualties, but hundreds of people killed and thousands of wounded are still unavoidable, if you really keep fighting one by one, fight more than 20, the Ming army on the south road will have more than half of the casualties, at that time, there will indeed be danger.

But the problem is that Zhu Cijiong only allowed Sun Chuanting to lead the army to conquer the four fortresses, which means that the Ming army on the southern road suffered a maximum of 10,000 casualties or 20,000 casualties, which is nothing compared to the 300,000 army, and the combat effectiveness will not decline much.

Golovin wants to know that the Ming army's goal this year is only eight fortresses, it is estimated that he has already led the army to leave, what is the point of running with the Ming army, anyway, if you can't find a chance, it is better to lead the army back to build a fortress, 200,000 people will build a fort in the first half of the year, at least more than ten forts can be built, which is much stronger than guarding here!

As for the attack of the Ming army on the east road, he naturally knew it, but he would not go there at all, because it was too close to the Ye Ni River, and the Ming army could get the support of warships at any time.

Sun Chuanting also did not march immediately after taking the No. 19 fortress, but still stopped, resting and recuperating while waiting for the army of the vassal state.

At this time, the city of Rem had been completed, and the vassal legions, including the 200,000 thorn captives, had also rushed over to repair the railroad one after another, and the progress of the railway was naturally extremely fast, and the railway was repaired soon after he took the nineteenth fortress.

He still ordered the vassal army to repair the No. 19 fortress, and then let them build a sub-city with a size of 10,000 people, and then build a small train in the sub-city, and after all this was completed, he led an army of 300,000 to the Tsarist No. 20 fort.

Fort 20 was also a small two-story fort that could only garrison two or three thousand people, and it didn't take much trouble to attack, but this time the progress of the railway was significantly accelerated, and before he could even take down Fort 20, the vassal legion built the railway to the vicinity of the fort.

I don't know how the defender of Tsarist Russia's No. 20 Fort felt when he saw millions of Ming troops gathered together, and he led 2,000 people to face millions of Ming troops and he was not so frightened that he surrendered immediately, I have to say that the deterrent power of Golovin's pork hook is still quite large!
