When Zhou Yafu and the generals came to Liu Che, Liu Che's eyes were still focused on the map.

"Your Majesty!" Zhou Yafu respectfully asked, "What are the orders of the edicts and others?" ”

"Does the Prime Minister know about Gaoque Fortress?" Liu Che asked.

"Back to Your Majesty, the minister knows: Gao Que, so Zhao Wuling King established, out of the Great Wall of the country, until the Yin Mountain, there are mountains interrupted, both sides of the strait, the clouds are lifted, such as the eyes of people, looking down on the Hetao, so it is called Gao Que!" Zhou Yafu replied: "Gao Que Stop, there is a strong city at the mouth of the plug, out of the north of the fortress is a wasteland, into it is across the mountains to build a village, easy to defend and difficult to attack, the minister's father once said: If you want to attack the Huns in the north, you must first cut down the Hetao, if you want the Hetao, you must first go down to Gaoque, Gaoque is not down, and it is difficult to recover from the Hetao!" ”

"During the reign of Emperor Taizong, Prime Minister Yingyin Yi waited for the Duke of Guan, led 85,000 people to ride a chariot, attacked Henan in the north, and chased the Huns beyond the clouds! He once sent light horsemen to go deep into the outside of the fortress and investigate the geography of Chalian. The envoy reported that the right virtuous king of the Huns led the people to defend Gaoque, and the city of Gaoque was difficult to attack, and it was impossible for manpower to attack! When the king of Jibei Xingju rebelled, Yihou had to collect troops and return to the south, that time in the sixth year of Emperor Taizong Xiaowen, twenty years ago! Since then, no one in China has been able to witness Gao Que with their own eyes! ”

Liu Che nodded.

Gaoque Fortress, in this era, has always been the focus of research and concern of the Han monarchs.

Because, it was the masterpiece of Zhao Wuling King Hufu cavalry shooting, and it was the limit of what Zhao could expand during the Warring States Period.

Li Mu once looked at the Hexi Corridor there, and Meng Tian also whipped him.

At the same time, Gaoque Fortress is also a key pass to hold the North River.

The term Beihe is rarely known in later generations.

But now, and for hundreds of years to come, it is a place name that the Central Plains civilization must pay attention to if it wants to operate the Hetao.

As we all know, the Hetao is a plain formed by the erosion of the Yellow River over millions of years.

The Yellow River is here, winding out of a zigzag bend.

Normally, when the plain river bends to a certain extent, the force of nature will scour a straight new channel at the protruding ends of the meandering section.

In geography, this is called cutting and straightening.

When the river is straightened, a new channel will naturally be generated.

However, the old river channel will not be abandoned.

Sometimes, when the water flow is large, the old and new rivers will coexist together and be used for a period of time.

Sometimes, the old river will become the main road again, and the new river will become a tributary.

It is only over time that the flow of the old channel decreases and gradually dries up that the new channel is established.

And the Beihe River is the name of the old road of the Yellow River in the Hetao Plain.

Today, the Beihe River is still the main river that can control the fate of the loop and plan the direction of the Yellow River, and sometimes even squeezes the new channel into tributaries.

Until the time of Li Daoyuan's "Notes on the Book of Water", the Beihe River was still the most important river in the Hetao Plain.

In the past wars, whoever controls Gaoque controls the Beihe, and whoever controls the Beihe may control the Hetao.

Historically, Wei Qing recovered the Hetao, and the historical records record that its attack route is the Jueziling, the Liangbei River, and the east through the south of Gaoque.

The Huns, of course, were not reconciled to defeat.

So, in the fourth year of Yuan Shuo, the Han and Hungarian fortresses around Gaoque Fortress broke out a major battle no less than the scale of the decisive battle of Mobei.

The right king of the Xiongnu will fight 100,000 horsemen with Wei Qing in Gaoque.

The result was a great victory for Wei Qing, and from then on, the Xiongnu no longer dared to look at the Hetao.

And Gaoque Fortress is also of great significance to future generations.

Because, if the location of the Gaoque fortress is determined, the boundary of the Great Wall of Zhao can be determined, and the boundary of the Great Wall of Zhao can be determined, and the direction of the Great Wall of Qin can be determined.

For this purpose, the essays and writings written by historians are piled up to fill a house.

However, no one can still be sure of the true and reliable location of Gao Que.

It can only be inferred from clues, roughly in a certain position.

And now, the monarchs and ministers of the Han family all know that Gao Que is in Yangshan.

Together with Qin Shi Huang's Yinshan defense line, it constituted the main defense system of the Great Wall of Qin to shield Hu Qi.

Yinshan is in Henan, while Yangshan is in Hebei.

In history, Meng Tian built the Great Wall, stretched for more than 10,000 miles, and crossed the river according to Yangshan.

Since the Northern Expedition twenty-four years ago, to this day, there is no Han monarch who does not want to regain the Gaoque Fortress.

Liu Che looked at Zhou Yafu, at Yi Zong, then at Bo Shi, and at those generals, and said, "I have already decided to start planning the Battle of Hetao!" ”

"The first stage of the campaign is to recover the Gaoque Fortress of King Zhao Wuling, Liangbei River and Yin Mountain!" Liu Che slammed his fist into the clearly marked location on the map.

"Lead the troops to fight, pout the division for thousands of miles, this is the length of the Qing and others!" Liu Che looked at the ministers and ordered: "I will give you ten days!" Ten days later, I will see the preliminary plan for the battle of Gaoque! ”

"This matter will be handed over to the prime minister to take the lead!" Liu Che distributed the task: "The general of the Che Cavalry is the deputy to assist, and the Qing and others are the staff officers to assist in the planning!" ”

"First calculate how many troops, how much grain, how many people, and how many people our army needs to mobilize to take Gaoque, and also calculate the possible direction and number of Xiongnu tribes!" Liu Che said: "After the plan is taken out, I will distribute it to the beings of Wuyuan for deduction!" ”

Do so, although there may be leaks.

However, it is more likely that the entire plan will be perfected.

"No!" Of course, Zhou Yafu will not refuse.

He even accepted the task with ecstasy.

In his lifetime, to be precise, during his reign, it was his greatest goal to recover the Hetao and complete the historical mission of restoring Qin's homeland!

Zhou Yafu will not forget that back then, when the old prime minister An Wen waited for Shen Tujia on his deathbed, he asked his family: Wang Shi is out of the plug, the north is captured in the single, and on the day of the family sacrifice, don't forget to tell Nai Weng!

Zhou Yafu didn't want to be like the old prime minister, when he was dying, he took the hands of his children and grandchildren and told him: Don't forget to tell Naiweng!

He wanted to see the invincible Xiongnu Shan Yu Long Banner being thrown to the altar of the Taimiao Temple when he was alive, and the Xiongnu Shan Yu was burdened with thorns, kneeling in front of the spiritual seat of Emperor Gao, bowing three times and knocking nine times!

If possible, dig up the coffins of Mao Dun and Lao Shang, learn from Wu Zixu, and whip the corpses!

Zhou Yafu raised his head and asked, "Your Majesty, what is the combat goal of the second stage?" ”

"Yinshan, of course!" Liu Che looked at the map and said lightly.

But to make the dragon city fly will not teach Humadu Yin Mountain.

Yinshan, in the long years, has always been the watershed that divides civilization and barbarism, and it is also the bottom line for the Zhuxia people to protect themselves from aggression.

Yin Mountain is in the hands of Zhuxia, and it is nothing more than the disease of scabies.

If Yin Mountain falls into the hands of the enemy.

The better ones were like the early Han Dynasty, harassed and invaded by the cavalry of the nomads.

Bad......

Take a look at the Five Dynasties, Ten Kingdoms and the Two Song Dynasties.

Without the shelter of Yin Mountain, the Hetao is exposed to the enemy's iron hooves and will be lost at any time.

As soon as the Hetao was lost, the entire northern gateway was wide open.

Moreover, China will lose one of its most reliable horse breeding grounds.

Relying on infantry to fight cavalry, even in the era of muskets, is a disadvantage!

Not to mention the era of cold weapons.

"In the third stage, before going out of Hexi, at least the road to Qilian Mountain must be opened!" Liu Che continued.

Losing my Qilian Mountain makes my six animals not rest, makes me Rouge Mountain, and makes my women colorless.

The tragic song of the Huns is the best commentary on the strategic position of Qilian Mountain and Rouge Mountain.

Liu Che believed that as long as the Han army was near Qilian Mountain.

Then, the military minister will definitely lead the main force back to the decisive battle.

This time, Liu Che will no longer be able to give the main force of the Huns a chance to escape or breathe.

It's just a pity that now, Liu Che doesn't know the geography and landform of Qilian Mountain and the surrounding terrain structure.

So there's no way to plan, that grand strategy.

Moreover, now, even Gaoque has not been taken, and even the important place in front of Gaoque, Ziling, is controlled by the Xiongnu.

At this time, to plan the battle of Qilian Mountain, it is a bit too ambitious.

It's better to focus on what's in front of you.

And Zhou Yafu came back and reported after consulting with Yizong and other generals: "Your Majesty, since you want to take Gaoque, then, please ask Your Majesty to immediately summon Shaofuqing, as well as the examination order, General Lou Chuan, and Moyuan's Juzi!" ”

He raised his head and looked at Liu Che, and said: "If you want to take Gaoque, you must Liang Beihe, and the ministers must confirm that the pontoon bridge technology and construction method of our dynasty are now!" ”

This is natural, Liu Che nodded and said, "Just according to the Prime Minister's opinion!" ”

He turned his head and instructed Ji Di: "Spread my edict, immediately announce: Shaofu Qing Liu She, the examination order and Shaofu Liucheng, and the general of the building ship Xu Han and Moyuan Juzi Yang Yi, immediately enter the palace to see me!" ”

Crossing the river is always a difficult problem in military warfare.

From the Spring and Autumn Battle of Hong and the Battle of Chengpu, how to cross the river has become a problem for military strategists.

And the Yellow River is now a raging river.

In particular, the water upstream is turbulent and turbulent.

Relying on a sampan to try to cross the river is simply wishful thinking.

What's more, today's Han army is already a cavalry-based combat force.

Therefore, if you want to cross the river to fight, you must build a pontoon bridge.

And to build a pontoon bridge, the most proficient in this way in the world is Shaofu and Lou Boat Yamen.

As for the Juzi called the Mo family to enter the palace, it is hoped that the Mo family will develop and improve a better, more convenient and safer pontoon erection method according to the existing pontoon technology.

"The ministers still want to know, Your Majesty, when do you plan to launch the Battle of the Hetao?" Zhou Yafu looked at Liu Che intently, and the other generals and princes were also short of breath.

In particular, the princes and emerging generals who did not go out in the last battle of Mayi were nervous about this answer.

They need to determine a specific time, and then they can go home to frantically spur and train their retainers and soldiers, and at the same time be ready to grab positions and occupy the pit.

The current Han army is actually undergoing a fierce reshuffle.

The intensity of this reshuffle is second only to the dumping of Zhulu that year.

In this reshuffle, only those who survive and survive can have a future.

Otherwise, it will die silently like countless famous and strong armies in the past.

And the key to this is military merit!

In the army, the comparison is who has more military achievements.

Whoever has more military achievements, more beheadings, and who speaks loudly, dares to ask for the best equipment, the best soldiers, and the best supplies from above! (To be continued.) )
