Datong is not close to Beijing, but it is not far away, but it is more than 700 miles from east to west.

If the highest standard of post transmission, that is, the speed of 600 miles of urgency, from Datong to deliver an urgent report to the military aircraft of the Beijing Division, one day and night, plus one day, is enough.

Therefore, when Fan Fucui and others divided Datong Town into four ways to defend, and Wu Fu, Zu Dashou, and Ding Qirui urgently rushed to Yanghekou, Deshengkou, Kill Hukou and other important places along the border to take command, Emperor Chongzhen received Fan Fucui's report in the Qianqing Palace.

The news that the slave chief Huang Taiji bypassed Ulan Hada and went west decisively, Emperor Chongzhen had received it a few days ago, and in addition to the unspeakable huge disappointment in his heart, he could only call in vain.

Although a series of fortifications, traps and traps that he had carefully prepared outside the border of Jizhen in the past two years, especially around Rehe Fort and Balihan, could not come in handy this time, but allowing Huang Taiji to retreat under the city of Ulan Hada could be regarded as avoiding a catastrophe outside the edge of Jizhen.

At the same time, it can be regarded as avoiding the fate of Gyeonggi being burned and ravaged by the Jianju army in history.

Therefore, after receiving the military report sent back by Sun Chengzong from the Rehe Town Guard, and learning that Huang Taiji gave up going south and went west, Emperor Chongzhen was both disappointed and relieved in his heart.

Disappointingly, the fortifications outside the border of Jizhen have not been used because they have consumed a lot of manpower, material and financial resources, and the deployment of troops in Gyeonggi is thick and intensive, and they have not played their due role when they have been waiting here for a long time.

The good news is that the thriving agriculture, industry, and commerce in Gyeonggi are now protected from the threat of invasion by the Jianjun.

After Jianyu went on an expedition to Chahar, at least the land of Gyeonggi was as safe as Mount Tai for the time being.

However, correspondingly, the crisis outside the borders of Datong and Xuanfu came ahead of schedule!

Before receiving the urgent report from Fan Fucui from Datong, Emperor Chongzhen had already been mentally prepared for this.

Therefore, after seeing the report of Fan Fucui and others, in addition to being surprised by Huang Taiji's decisiveness and resoluteness and the scale and speed of the Jianyu cavalry's march, he was not surprised by Huang Taiji's march to Monan.

At the same time, now Emperor Chongzhen is not satisfied with the response measures of Fan Fucui, Zu Dashou, Wu Fu and others, but he can understand it.

The hatred and mutual distrust between the Mongol Tatars in Monan and the Ming border armies in Datong and Xuanfu have not been a year or two.

On the contrary, this mutual hatred and mistrust has been going on for more than 200 years.

In this kind of atmosphere and situation, unless a person has a strong sense of the overall situation and the overall situation, he can help his previous enemies regardless of his past suspicions.

Otherwise, it would be impossible for anyone to easily turn enemies into friends or even fight side by side with the enemy who had fought each other for more than 200 years.

However, although Emperor Chongzhen was able to understand the actions of Fan Fucui, Zu Dashou and others, it did not mean that he would support their practices.

On the contrary, after receiving Fan Fucui's report, that night, Emperor Chongzhen sent a decree to Fan Fucui in the form of a secret decree, ordering him to immediately agree to Lin Dan Khan's request.

And contact Lin Dan Khan's messenger as soon as possible, go all out to rescue Guihua City, and jointly fight against Huang Taiji's Jianyu army, and resolutely cannot let Huang Taiji easily take Monan Mongolia.

At the same time, Emperor Chongzhen praised Fan Fucui's strategy of encircling Wei and rescuing Zhao mentioned in the report, that is, the strategy of attacking the hinterland of Jianyu with troops and horses from Liaodong Town and Dongjiang Town to relieve the crisis in Monan.

And in this same secret order, Chen Shiqi, the Datong military commander who took the lead in proposing this strategy, was directly elected to the Military Aircraft Department to serve as a military aircraft counselor.

Is Chen Shiqi's idea special?

Actually, it's not special at all.

At least there is nothing new for the current Emperor Chongzhen.

Because this is also the strategy that Emperor Chongzhen has been thinking of for a long time.

However, Chen Shiqi, who was a Jinshi in the fifth year of the Apocalypse and was a member of the Datong Army, was able to put forward such an idea when Mo Nan was in crisis, and among the Jinshi civil officials in the late Ming Dynasty, he was one who was more sober-minded and had a greater view of the overall situation.

If in history, when Huang Taiji led the Manchu army to invade Gyeonggi and stopped troops under the city of Jingshi, Emperor Chongzhen was able to send an army to advance to Shenyang by land or sea, then the offensive and defensive situation between the Ming and the Later Jin Dynasty was likely to be changed all of a sudden.

Even if the army sent out can't take the land of Liaoshen, Huang Taiji, who is under the city of Jingshi, will inevitably retreat in a hurry.

It's a pity that Emperor Chongzhen didn't do this in history, and at that time, the Manchu Dynasty was in a panic, and they all took defending the capital division as their first priority, and no one made this suggestion to him.

Later generations read history so far, and every time they sigh, since they have crossed over to become Emperor Chongzhen in this life, they will not leave the same regrets.

And Chen Shiqi, a literati scholar in the late Ming Dynasty who did not have an eye, was able to clearly put forward this suggestion at this time, and he could also be regarded as a person who knew the soldiers among his contemporaries.

At this time, the Military Aircraft Department also happened to lack such a Jinshi civilian officer with an overall view.

On the morning of the second day after receiving the urgent report from Datong, Emperor Chongzhen's secret decree was sent out of the Beijing Division, and the Jinyi guards carrying the secret decree galloped all the way west at an expedited speed of 600 miles.

However, when the personnel of Jinyiwei who delivered the secret decree changed horses and did not change people, galloped day and night, and finally rushed into Datong City on the morning of October 17, the second year of Chongzhen, the situation in the Monan area outside the Datong border had taken a sharp turn!

It is said that Zu Dashou led more than 8,000 elite horse infantry troops of Datong Town, which had been selected and trained since he was transferred to Datong, and at dusk on the day when he moved the town to the victory pass of Datong, he saw above the attic of the north gate of the Victory Fort that one after another cavalry teams belonging to the Jianyu with yellow flags and red flags were beating horses from the endless grassland a few miles away from the north gate of the Victory Fort.

On the night of the same day, Li Quan, the general of the Victory Fort, picked up the letter from the Red Flag Banner Lord Yue who sent people to the city at the north gate of the Victory Fort.

In a letter to the officers of Fort Victory, Yue Tuo said:

"Dajin and the Ming State have sent envoys to negotiate peace in Liaodong, this time the army came to Monan, just to conquer Lin Dan and avenge the world, it has nothing to do with the Ming State, just to claim back the Ye He remnants under the protection of Lin Dan Khan, Dajin immediately withdrew the army, please ask the Ming border general to restrain the men and horses under his command, and the two will not offend each other!"

Yue Tuo also assured in the letter that as long as the Ming army remained neutral and did not send troops to aid Lin Dan Khan, then the Jianyu army would never open a border provocation and launch an attack on the border forts along the border of Datong.

After Zu Dashou got Yue Tuo's letter of submission, he asked people to copy it and forward it to Datong, and at the same time summoned the generals to discuss countermeasures in the Victory Fort.

Regarding the statement of Yue Tuo, the master of the red flag, Zu Dashou has been in Liaodong for a long time, and of course he will be suspicious.

However, based on his experience in the border passes of Jiuzhen, it was inferred that the north and south roads of Jianyu attacked Lin Dan Khan with such a large army, even if Lin Dan Khan had a city like Naturalization City to rely on, it was only a matter of time before the city was broken and defeated.

Unless he leads the elite border army of Datong Town to rescue Guihua City.

That night, I saw the army of Jianyu with red flags and yellow flags marching westward from outside Fort Victory, and Zu Dashou brought the generals.

Zu Dashou said: "The prosperity of the troops in this town is unexpected, if it is only for the sake of raising troops to fight Lin Dan Suoyehe, it will not be like this." Since this is the case, the plan of the building will be great.

"Thinking about it now, what Lord Wu said before the superintendent is not unreasonable. If Lin Dan Khan is really vulnerable and quickly defeated, then Jianyu will raise troops to attack again, and my Datong Town will not be in danger! ”

After Zu Dashou said this, he looked at the henchmen and generals above the attic of Guancheng with a worried face.

At this time, Zu Zeyuan, a guerrilla of the Chinese army of the General Military Mansion of Datong Town, looked at his uncle's face and said:

"Lord Shojo don't worry! Although Guihua City and Datong Town are cold, it is not necessary to rescue Lin Dan Khan, but it is really impossible to do it!

"The imperial court guards the Datong with adults, and prepares Mongolia. Now the Jurchens have come to ask for Lin Dan, and the adults have not been ordered to help Lin Dan, but they are also helping the enemy. If the Jurchens come here under the pretext of the old school, the court will offend the general!

"If you sit on the mountain and watch the tiger fight, if the Jurchen defeats Mongolia, when the Jurchen soldiers return, I will go out to attack Mongolia, and it will be easy to set the desert south. If Mongolia defeats the Jurchens, I ask for an order to attack the Jurchens, so that they can avenge the country and marry the Mongols.

"At the end of the day, Mongolia is near, and Jurchen is far away. Even if the Jurchens defeat the Mongols, they will not be able to stay here for long! If you can do this, my Datong Town can be invincible!

"What's more, this time the Jurchens are coming to the country, and their momentum is great, and they are afraid of no less than 150,000 elite cavalry on the north and south roads. Please think twice! ”

A direct result of Zu Dashou's careful thinking and prudence was that the elite border army of Datong Town, which had more than 13,000 people in the Victory Fort, just watched as the Jianyu Left Road Army led by Yue Tuo and others quickly passed through the victory pass and went straight to Guihua City, which was 300 miles away to the west.

A more serious indirect consequence was that the next morning, the Chahar army, which was rushing out of Kuku and Tunxi Gate in a panic, crowded on the east bank of the Hatun River, and marching west across the river in confusion, suddenly encountered an attack from behind by the men and horses of Yuetuo, Haoge, and Zaisang, and completely fell into collapse and chaos. 2510
