Altan Khan fled, and the defenders of Songshan Fort were suddenly demoralized, and the eastern walls were still shouting and killing, but the southern, northern, and western gates were already open, and the fleeing foot soldiers poured like a tide to the northwest.

Yu Dayou obviously felt that the pressure around him was relaxed, and when he raised his head and looked around, he suddenly couldn't cry or laugh.

It turned out that there was no resistance on the eastern wall at this time, and the Tartar foot soldiers basically ran away, and those who couldn't also threw away their weapons and surrendered on the ground.

This tartar is too unbeaten, right?

At this time, a staff member crossed the crowd, stepped forward quickly, and said with a little anxiety: "General, the other three city gates have been opened, and the Tartars are fleeing in flocks, are we dividing our troops to catch up?" ”

Yu Dayou shook his head without thinking about it: "Forget it, poor Kou Mo chases, let them go." ”

When the general heard this, his face couldn't help showing a hint of loss, but he still honestly surrendered his hand.

Of course Yu Dayou knows what his subordinates think, those Tartars who escaped are all money, as long as they catch up, whether they live or die, they are all one hundred and two, and if they don't let them earn so much silver, they will naturally be a little lost.

He can't help it, it's Yang Cong who won't let him chase him.

Before coming this time, Yang Cong gave a strange order, Tartar, if you can, you won't catch it, and if you can let it go, you will let it go, saying that it is to consume the food of Tartar.

Well, these Tartars do have to eat after they flee back, and the grasslands basically don't produce food, which is indeed a good way to defeat the enemy.

This was the end of the battle of Songshan Fort, and the Ming army took this fortress temporarily piled up by the Tartars with very few casualties, and since then there has been no danger from Ningxia Wei to the front line of Ganzhou Town, and the fortress advance tactics have been continued.

Altan Khan saw that the Ming army was about to cross the Great and Small Song Mountains and seal the northwest exit, so he had no choice but to lead his main Tatar army to retreat north in panic.

In less than half a year, the fortress between Ningxia Wei and Ganzhou Town was completed, and at the same time, Ganzhou Town, the westernmost border town of the Ming Dynasty, was also connected with other border towns by railway.

Since then, the nine sides of the Ming Dynasty, except for the easternmost Liaodong Town, the other eight border towns have been connected to the railway, whether it is the transportation of grain and grass or the support of troops, it is very convenient and fast.

After the construction of this section of the railway, there is another benefit, that is, the border defense line between Ganzhou Town and Ningxia Wei Line has been shortened by more than half.

Originally, the defense line of the Ming army was along the Yellow River bending and extending to the northwest, and now it became a straight line, and the defense line of the three towns in Shaanxi was originally three or four thousand miles, but now there were only more than 1,000 miles left, and in the middle, I don't know how many troops can be saved.

Of course, in order to shorten this defense line, there is a premise, that is, a Great Wall must be rebuilt on the north side of the railway line from Ningxia Wei to Ganzhou Town, otherwise, a fortress with an interval of dozens of miles is not enough to ensure the safety of the railway line, nor can it completely block the Tartars.

This section of the Great Wall, in general, is more than 500 miles, and there are railway transportation materials and food supplies, so it is not very difficult to repair.

Yang Cong gave an order, more than 100,000 elite border troops and garrisons went into battle, less than two months, more than 500 miles of the Great Wall was completed, and the Ming army also built a huge Songshan City on the site of Songshan Fort, the area of the city is comparable to the general state city, and there is no problem with stationing 100,000 troops.

In other words, why did Yang Cong build such a large city in the Northwest Wasteland?

There is no arable land, there are no resources, food is transported from other places, and there is no basic self-sufficiency, so it is a waste to build such a huge city!

Yang Congzhi naturally built this city for a reason, because this city has a lot to do with his next strategy.

So, what's next for him?

On this day, in Songshan City, where the city wall had just been built, the generals of the Ming border army gathered, and the prince and prince, the cabinet scholars, and Yang Cong, the Hou of Hui'an, summoned them over for the next strategic deployment.

At this time, there were no buildings in Songshan City, so all the generals attending the meeting were summoned by Yang Cong to the temporary marshal's tent, he majestically glanced at the generals on both sides, and then went straight to the point: "Everyone, the Great Wall from Ningxia Wei to Ganzhou Town has been built, and our first phase of the battle is over, and next, we will implement the second phase of the strategy." ”

When the generals heard this, they were all dissatisfied with their faces, you know, at this time, there are 120,000 troops gathered in Songshan City, it can be said that the elite of the border army that can be assembled at this stage have been assembled here, it is obvious that Lord Yang is going to have a decisive battle with the Tartars and defeat the Tartars in one fell swoop.

Such a battle, if you can participate in it, meritorious, it is simply immeasurable, and it is very likely that fighting this battle will be enough to make them proud for a lifetime!

Yang Cong then said aloud: "The strategy of this second stage is very simple, everyone knows how the Tartars entered the northwest border town of Kou before, let's use the way of others to govern their bodies, and constantly harass the grassland where they gather, so that they are not at peace." ”

His move is similar to Altan Khan's construction of Songshan Fort to block the footsteps of the Ming army.

Altan Khan saw that the Ming army's fortress advance tactics made him helpless, so he also followed the Ming army to build a fortress to block the pace of the Ming army.

Yang Cong is harassment of the Tartars made the northwest border of the Ming Dynasty unstable, and the imperial court had to spend a huge amount of money to maintain the number of troops in the northwest frontier, so that the Ming Dynasty was burdened with a heavy burden and gradually declined.

This time, he wanted to put a heavy burden on Altan Khan's back and let the Tartars go into decline.

Altan Khan's strategy has failed, can his strategy succeed?

The generals present did not show any embarrassed expressions, but everyone had a little surprise on their faces.

Obviously, they don't think that there is any danger in leading the army to harass the Tartars, because the elite equipment of the border army is terrifyingly good at this time, whether it is a chariot or a gun carriage, it is the nemesis of the Tartar cavalry, if the Tartar cavalry dares to start a war with them, it is no different from seeking death, they are afraid of a fart!

Question, does this harassment tactic work?

Da Ming has been harassed by the Tartars for more than a hundred years, isn't it still standing?

Yang Cong immediately gave the answer to this question.

He explained casually: "Our situation is different, you know? We have a lot of land and resources, and there are countless places where food is produced, and the Tartars just enter the northwest and can't make the Ming Dynasty collapse. The Tartars do not have such a deep heritage as our Ming Dynasty, they basically live by grazing, and at this time, the most abundant pasture in the east and west of the south are occupied by us, and they can only rely on a limited number of small grasslands in the north to survive. Think about it, if we stop the army from harassing it from time to time, will they be able to withstand it? “
