However, he said that after Wu Yanzhi arranged the construction of a soda ash refining workshop here, he was ready to leave for Taiyuan to return to Taiyuan. Unexpectedly, he received an urgent letter from the imperial court that night.

It's not surprising that he was promoted, but it was quite surprising that he was the protector of Anbei.

Although he suggested the construction of the Three Surrender Cities, he didn't expect that he would let himself be the protector of Anbei.

To tell the truth, there are many ethnic minorities in Hequ, and the living conditions are very poor, so of course it is not attractive to Wu Yanzhi.

However, the people he recommended were all promoted as usual, and Wu Yanzhi was naturally very happy. So he hurriedly gathered all his staff and officers above the rank of lieutenant to a meeting to study the construction of the city and the defense of the Turks.

Wu Yanzhi didn't like to talk about clichés in meetings, so he went straight to the point and said: "Everyone, I invite you to the meeting at such a late hour, because I have two things to tell you.

The first thing is a great event, all of you have been promoted to a high rank, and you all have a meritorious position. Staff officer Yang Siqiao has been promoted to the post of Doctor of Wupin Chaosan, and General Lang of the Right Prison Guard.

Qi Xuan's rank was also raised to the seventh grade, and the title of the palace attendant was added. Yao Kuan and Yu Fei were promoted to the lower rank of the seventh rank and gave the captain ......"

He first told everyone about their promotion, and the room was immediately noisy, and everyone was excited: "Congratulations to Yang Gong for his promotion to the fifth rank of high office." ”

"I didn't expect that my rank has also been upgraded by two ranks, and my rank has been increased by two turns."

"Yes, although my rank has only been increased by one order, the rank has been increased by six turns, and it is already the highest Upper Pillar Kingdom."

Everyone was talking to each other about their promotions, and then someone asked with a smile: "General Wu should also be promoted, right?" Tell the brethren too, and we will rejoice too! ”

A fat lieutenant in his 30s asked.

Wu Yanyi saw that these people all regarded themselves as brothers, and they spoke more directly, which was very good.

So he smiled and said: "Thanks to the strong support of your brothers, others have also been promoted to the Yinqing Guanglu doctor from the third grade." ”

"What? In the silver Qingguang Lu doctor? Didn't General Wu be promoted to the king of the county? One of the lieutenants was a little unconvinced.

Wu Yanzhi smiled and said, "Captain Wang, do you think the county king is so good?" ”

Then the crowd gossiped again.

At this time, Wu Yanzhi continued: "You have another news, that is, we will not return to Taiyuan for the time being, and we will build the Three Surrender Cities here.

We need to defend against a Turkic sneak attack. Even the nearly 10,000 soldiers in Taiyuan will rush here......"

Next, he explained the contents of the Book of the Imperial Court in detail.

"The Turk is just in time, and we are fighting him!"

"Follow General Wu, we are not afraid! But we don't know how to repair the city......"

At this time, Qi Xuan said: "The imperial court really agreed to our suggestion, and the repair of these three surrendered cities is the work of thousands of generations. It is extremely beneficial to my big week, and we still have to study a safe plan first.

Although it took three months, it would take seven or eight days to travel from here, and it would take a lot of time to design the city and gather people to collect materials. Three months is actually a very intense time. ”

When he said this, everyone's expressions suddenly became serious. The court demanded three months to complete the project, but it was no joke. In addition, the Turks may come to harass it!

At this time, Yang Siqiao said: "I think we must study the specific construction sites of these three surrendered cities overnight, including the scale of construction. Also, along the important intersections of Niutou towards Nashan, 500 miles away, it is necessary to build beacon towers to give alarms.

Between the three cities, there should also be enough beacon towers, and the roads should be leveled to ensure that they can support each other. ”

That Qi Xuan also said: "I also agree with General Yang's opinion!" The detailed addresses of these three surrendered cities were also carefully considered in his heart

First of all, these three cities had to be built on important crossings north of the Great River, so that they could attack at any time and control the area north of the Great River and south of Yinshan.

Second, there should be enough land around the three cities to ensure the self-sufficiency of the garrison troops to the greatest extent, that is, it is necessary to do a good job in the work of cantonment fields and reduce the transportation of grain and grass from other places.

Thirdly, it was suggested that the surrendered city should be built at a ferry port 80 miles outside the city of Yongfeng; The city was built 300 miles east of Fengzhou, that is, 30 miles south of Huyan Valley. The city of surrender in the east was built in Yulin, Shengzhou.

As for the location of the Anbei Metropolitan Protectorate, it is recommended that the city be surrendered in the middle or the city in the east, and it is better to surrender the city in the middle. This would give confidence to the soldiers of the Western Surrender City, after all, the three cities spanned 500 li, and it was best to have the protectorate in the middle. ”

Wu Yan looked at it, this Qi Xuan was also powerful, and he didn't use the wrong person. The head of his analysis is the Tao. Although he is not a liberal arts student, he is also quite good at history, likes weapons, and likes to read the history of war.

It should be added here that the address of these three surrendered cities is now the Hetao Plain. The Yellow River made a big bend there, taking on the shape of "several". The city of Sanshou is located in a horizontal position above the word "several", and the geographical location is extremely important.

He also knows a little about the common sense of war. There is a cloud in the art of war: the time is not as good as the location, and the location is not as good as the people. In fact, this war mainly depends on geographical advantages. As long as you occupy the favorable terrain, the enemy will always have a million strong soldiers.

It is these three cities, whether they are built in Hebei or Henan, it is very particular. Building in Hebei, of course, is an offensive posture. If it is built in Henan, this will definitely be a defensive posture, and the effect will be very poor.

Historically, if the Tang Dynasty had not controlled the four towns of Anxi, the map of northwest China might have had to change. Although the four towns of Anxi were lost in the late Tang Dynasty, the roots that had been planted there for hundreds of years could not be uprooted.

The same is true of the three surrendered cities. In addition to controlling the meander, it controlled the area south of Yinshan, and only then did the Anshi Rebellion in the Tang Dynasty have Shuofang Jiedu to resist. Otherwise, this place would have been occupied by the Hui Hui long ago, and the Tang Dynasty would have perished nine times out of ten.

Even if he didn't perish, Tang Xuanzong could only shrink in Xishu, and whether he could be Liu Bei or not is still two words. There is no doubt that those five dynasties and ten kingdoms may have arrived more than a hundred years earlier.

Next, some staff members and several lieutenants expressed their opinions. These people mainly put forward some specific strategies and tactics on how to prevent Turkic harassment.

This specific strategy and tactics is to mainly use the Yinshan Mountain Range to defend against the enemy. The Hetao Plain area south of the Yinshan Mountains was brought under the control of the three cities. There are abundant pastures and plenty of arable land. 100,000 soldiers and their families have no problems defending here.

That is, in a poem by the famous poet Wang Changling of the Tang Dynasty: In the Qin period, the bright moon and the Han period, the Long March has not been returned; But to make the dragon city fly, do not let Hu Ma do Yin Mountain!

There are three lines of defense in the north, and Yinshan is the natural first line of defense; The three surrendered cities and the Yellow River form the second line of defense; Relying on the garrisons of the Great Wall and the northwestern states, the third line of defense was formed.
