The Ming fortress group continued to advance, firm and steady, each time the chariot formation went first, protecting the front and the two wings, and then quickly building the fortress, with almost no holes in between.

Altan Khan was desperate to find that the opportunity he had imagined had not come, on the contrary, as the Ming army advanced into the fortress, his tribes had ushered in a crisis first.

As for the reason, it is very simple, because the fortress group of the Ming army extended from east to west, and all his tribes were concentrated in the northwest of the Hetao.

In other words, when the Ming army's fortress advanced more than 200 miles, the forward army's chariot formation had already entered the grazing land of his tribes.

At this time, he had to consider a question, whether to fight or withdraw?

In many cases, fighting a war is not as simple as a one-time battle to the death.

There are many factors to consider in fighting a war, and the simplest is that you have to think about whether you can win by rushing forward.

If you know that you can't win by rushing up, and you still rush up, then it's not a war, but a death!

Altan Khan was not a reckless man, and he certainly knew that there was a need to consider success or failure in war.

At this time, in the face of the dense artillery of the Ming army, he didn't even have the courage to lead the cavalry to charge, how could he fight this battle?

Obviously, this battle can't be fought!

Even if he recruited the cavalry and foot soldiers of the Bu Pura Division, the Bu'er Children's Division, and the Uliang Ha Division, he would not be able to fight them, not to mention, he might not be able to recruit people at this time.

The tribes on the grassland are like this, when you are so strong that you are desperate, people have no choice, they will choose to give in, once your strength is not good, people will leave you, and even turn around and oppress you!

This is the rule of the grassland, and it has been the case for hundreds of years.

For example, when he was in Japan, the Warat Department was so powerful, even the Ming Forbidden Army was defeated by it, and the Tatar Ministry could only obey its orders, and did not dare to disobey it in the slightest.

The overlord of the grassland is not so easy to be, once your strength is not as good as others, you will only be conquered by others.

This is also the main reason why Altan Khan did not dare to fight hard with the Ming army, he was really afraid, afraid that his strength would plummet.

In case, rushing to fight hard and scrapping all the 50,000 elite cavalry under his command, the Tatar tribe will become a vassal of other tribes even if it is not destroyed by the Ming army.

As a hero on the grassland, how can he be willing to be subservient to others.

Therefore, he can't fight hard with the Ming army, he must preserve his strength, since he can't fight, then he can only choose to retreat.

So, as soon as the Ming army vanguarded the tent of the Tartar tribe, it disappeared again within a few days.

Yang Cong was helping Wang Xuan command and dispatch materials in Gushan Fort at this time, because Wang Xuan had already taken Tunwei to repair the railway, and he had no time to manage the dispatch of materials.

On this day, he had just sent a batch of sleepers to the front, when the guards outside suddenly said loudly: "Report, General Yu has a military report." ”

Yu Dayou is reporting the military situation at this time, it can't be that the Tartars are preparing to attack again, right?

When Yang Cong heard this, he hurriedly said aloud: "Quick, present it." ”

Soon, one of the guards walked in with an envelope.

Yang Cong took the envelope, took out the letter paper inside, and suddenly showed a strange look on his face.

What Yu Dayou reported was not that the Tartars were preparing to attack, but that the Tartars were missing again!

What does this tartar mean?

He put down the letter in his hand and stared at the map on the table, lost in thought.

At this time, the fortress was half repaired, and the battle line had advanced to the middle of the Hetao grassland, in order to prevent the Tartars from carrying out surprise attacks, he had ordered Yu Dayou and Tang Kekuan to send scouts respectively, and ventured deep into the grassland to spy on the situation of the Tartars.

What is strange is that there is no trace of Tartar in the southeast of the Hetao steppe, and the entire steppe is almost empty.

In other words, the Tartars did not set up an ambush behind them at all, and all the Tartar tribes seemed to have moved to the northwestern part of the Hetao.

Is Altan Khan ready to abandon the Hetao steppe?

He wondered what was going on in the northwestern part of the Loop.

It's a pity that the Tartars' defense of the northwest is very tight, and the scouts sent by Yu Dayou can't penetrate at all.

In the past few days, I finally met a Tartar tribe, and they disappeared again, what does Altan Khan mean by this?

He stared at the unexplored areas on the map for a long time, but still couldn't figure out what this Altan Khan wanted to do.

It stands to reason that this guy will have to launch a few raids no matter how much he does!

Could it be that this guy just gave up?

It's unlikely, Altan Khan is a famous hero in history, where can he be so cowardly?

How did he know that this was not a question of cowardice at all, there was no royal law on the grassland at this time, not that whoever became a Great Khan, everyone must obey his orders.

At this time, the grassland is completely talking with fists, and whoever has the big fist is the boss.

Altan Khan was afraid that if he made a move, he would break his fist, or even lose his fist, and thus lose his position as the overlord of the steppe, so he never dared to launch a surprise attack.

Altan Khan has not dared to make a move, the fortress advanced very smoothly, within a few months, the Ming army has built the fortress to a position less than 100 miles from the Ningxia avant-garde, and at this time, all the tribes of the Mongol and Yuan Tatar tribes in the Hetao have been crowded together.

Now, Altan Khan is convenient, if he wants to gather his 50,000 elite horsemen, he only needs to give an order, and within a day, 50,000 elite horsemen will gather under his command.

Question, what about the assembly, go up and fight the Ming army?

If he is cornered, there is only such a little territory left, then, even if he is unwilling, he has to fight with the Ming army, the problem, at this time, he is not more than this bit of territory.

The so-called Hetao of the Ming Dynasty is actually only the East Loop in the eyes of the Tatar Department, that is to say, this piece of the Yellow River bend is not the whole of the Hetao, and the Tatar Department also occupies the west of the Yellow River Bend, which they call the West Loop.

Although the west set is not as fertile as the east set, there is still no problem with grazing, but the climate is not very good.

In other words, Altan Khan did not have no way to retreat, and he could completely move all his tribes to Xitao to avoid the edge of the Ming army.

However, this clan does not mean that it can be moved away, and he must also consider the consequences after moving.

If he moves away, his reputation on the grassland will definitely be dealt a serious blow, and it is indeed embarrassing to be occupied by someone who has occupied his nest and does not dare to fight back.

Question, what if he doesn't move away?

Will you stay and fight the Ming army?

If he stays and fights with the Ming army, the Ming army will not necessarily be finished, but he will definitely be finished.

What are you kidding, there are more than 100,000 horses, and there are countless muskets and artillery, even if he carries 50,000 elite horsemen to carry out a sneak attack, he can kill 50,000 people and horses.

Does it make sense to kill 50,000 people?

It doesn't make any sense, there are still 50,000 horses left, and he is crippled.

The ending is still the same, he still has to give up the East and flee to the West Set.

There's no way, Da Ming, some are guards, some are border troops, and he only has so many strong men under his hands that he can't afford to spend it at all.

In desperation, he could only choose to give up the East and move all his tribes to the West Set.
