"Su Dawei, the former governor of the Tang Dynasty, commanded 12,500 cavalry, including 6,000 cavalry, 20,000 horses, and 4,500 armor soldiers.

Among these armor soldiers, there were 2,500 crossbows and swords.

Each person is equipped with a bow and thirty arrows, and there is a long-handled Mo knife and a spear inserted behind the back.

In addition, the cavalry also had a bow, thirty arrows, a spear, and a horizontal sword.

In addition, the crossbows in this army have a range of 300 paces for the Fuyuan crossbow, 230 steps for the open crossbow, 200 steps for the horn crossbow, and 160 steps for the single-bow crossbow. ”

"It is believed that this army is also equipped with a new type of crossbow, which is rumored to be twelve stones strong, with an axle to turn the car and open the bow, there are seven arrows on the crossbow arm, and a huge arrow is placed in the center of the arrow, which is three feet five inches long and five inches thick, with iron leaves as the feather, and three slightly smaller arrows are placed on the left and right, and all the arrows are fired in a volley, and all of them are invincible."

In the night, a muffled voice seemed to murmur.

There was a chill in the thin smoke.

Crane Langjun, dressed in white, stood in the black mist, bowed respectfully to the tall figure on a boulder in the distance.

"This Tang army is well-equipped."

The black shadow on the boulder snorted coldly.

He was nearly ten feet tall, wearing a black and white striped coat, a flat crown on his head, and his hands in his big sleeves.

The most striking thing is his face.

On that face, there was a bronze ghost face and a green fang.

The ghost face was shining in the moonlight, shining with an icy blue light, which was terrifying.

"Big Dipper Star Monarch, we want to eat Chang'an blood food, why bother with that centaur?"

"You know what."

The star lord on the boulder turned.

Only then did he find that the big slab on his chest was embroidered with the Big Dipper.

"If humanity is prosperous, then our people are weak, and only by constantly weakening their strength can we become stronger. The Tang people are strong, they are stronger than their iron horses, if they want to eat blood food, these people had better disappear forever. ”

"I understand, I'm going to arrange the clansmen ......"

"Wait."

The Big Dipper Star Monarch waved his sleeves and said coldly: "We don't need to make a direct move, let them fight with Tubo, wait for both sides to lose, and then fight again." ”

"Xingjun Gaojian!" Tsurumo-kun let out a strange laugh.

Black smoke billowed and the heavens and the earth were obscured by darkness.

Chaos is boundless.

……

"There are still a few routes, but they are not as good as taking Dafeichuan, the benefits of attacking and ambushing the city are great, if you can capture the capital of Tuyuhun Wang, you can announce the restoration of Tuyuhun, and you can't achieve this effect from other routes."

Wang Xuance looked at Su Dawei with some strangeness: "Does Manager Su think this route is not good?" ”

"Hmm......"

How to explain to you that this marching route can be called a "sinkhole" in the history of the Tang Army.

In history, Xue Rengui and Guo Beifeng led 50,000 Tang troops to leap over Dafeichuan to attack Tubo, but Guo Beifeng's mistake was caught by the famous Tubo general Non Qinling, and the Tang army's grain, grass, baggage and reserve personnel were lost.

Xue Rengui led more than 10,000 cavalry to cross the Dafei River at that time, and knocked out the horse farm of the Tubo people on the grassland.

However, under the huge numerical disadvantage, Xue Rengui could only lead the remnants of the army to retreat to Dafeichuan, set up a walled city by the mountain, and confronted hundreds of thousands of Tubo troops.

The final result was that Xue Rengui and Guo Beifeng were able to lead the remnants of the Tang army back to Chang'an.

It was this defeat of the Tang Army that broke the myth of the Tang Army's invincibility.

After Dafeichuan, the Tang Dynasty spent decades to quell the rebellion of the Quartet and re-stabilize the defense line torn apart by the Tibetans.

"Chief, this route has great benefits, if we defeat Fuqi City, it will not be a problem to help Tuyuhun restore the country, it can be said that the goal of this battle is half completed."

"Doesn't the chief approve of this route?"

Li Wei and Cheng Wuting both asked curiously.

They are all old in the military, and if Su Dawei wants to convince these generals, he must at least come up with a reasonable reason.

"Ahem, we know the importance of Fu Qi City, and the Tubo people must also know that if we enter the army like this, I am afraid that we will fall into the calculations of the Tubo people."

"This matter is not difficult, as long as we send more scouts and set up more suspicious soldiers, then the truth will be false, so that the Tibetan people think that we are bluffing, taking advantage of the enemy's inability to specialize, we can turn the false into real according to the specific situation, and attack it to be saved.

You can even use the city of Fu Qi as a bait to fight a decisive battle with cavalry and wipe out a large number of Tubo people. ”

Li Wei's eyes shone as brightly as an eagle, and when he said this, he was full of confidence.

He belonged to the Shaozhuang faction in the Tang Army, that is, the so-called hawks, and had a strong desire to take the initiative.

Cheng Wuting is more low-key and pragmatic than him: "Even if the Tubo people know that our army will take this route, it is impossible to know our specific time for using troops, as well as the arrangement of manpower and troops, so they can attack the city of Ambush and then set up an ambush at the intersection."

As long as the Tibetan people come to the rescue, they will ambush the soldiers and encircle and annihilate them.

This siege Wei to save Zhao's plan. ”

Although the two people say different things, they probably mean the same thing.

It is just that we can't give up the route of Dafeichuan.

Because this line belongs to "attacking the enemy must be saved".

The Tubo people will inevitably be heavily guarded, and the Tang army was originally looking for the Tubo people to fight a decisive battle, but they can take advantage of this matter to make a big fuss.

When it comes to playing the art of war and strategy, the Tubo people can only be regarded as the younger brothers of the Tang people.

The Tang Dynasty is very contemptuous of the Tibetan people.

Su Dawei groaned and looked at An Wensheng on the side.

Although he didn't understand why Su Dawei was dissatisfied with this traditional route of marching, An Wensheng, who was familiar with him, immediately said: "The benefits of jumping over Dafeichuan and marching into Ambush City are huge, but the risks are also great, so you can make a temporary alternative."

You can think about some more possibilities, compare the advantages and disadvantages, and then make a conclusion. ”

When the troops were dispatched, Li Zhi and the military department gave Su Dawei the main task of bluffing, dragging and delaying Tubo to digest the land of Tuyuhun.

But he did not ask Su Dawei to use the troops specifically.

The military mechanism of the Tang Dynasty, which was generally like this, gave a clear goal, and then the generals in front had considerable autonomy.

Wang Xuance paid attention to Su Dawei's expression, stroked his thick beard and said: "Traditionally, going to Tubo to take Wuwei and passing through Dafeichuan is the shortest distance and the most economical food and grass.

The second is to pass through the Hexi Corridor, according to our route to Tianzhu, passing through the countries of the Western Regions......"

After Wang Xuance's explanation, Su Dawei finally had a more intuitive understanding of the terrain of Tubo and Tuyuhun.

First of all, the map of the Tang Dynasty resembles a "rooster" but there is a large piece on the back of the chicken, which is the Outer Mongolia of later generations.

During the Tang Dynasty, it was originally a steppe tribe ruled by the Turks.

Nowadays, these are the lands of Datang.

Followed by the chicken butt part, the territory of the Tang Dynasty extends all the way to Central Asia.

The part of Tocharian bordering the Great Eclipse and is even close to Khorasan.

If you don't consider these two extra pieces of land, Datang Chang'an is basically in the center of the "rooster".

From the map, there are three routes to Tibet.

Up, is to take the Hexi corridor and draw a parabola on the rooster's butt.

It was necessary to travel from Gansu to Xinjiang in later generations, bypassing the vast grasslands, and passing through the countries of the Western Regions before entering Tibet.

That land has the four towns of Anxi, the Anxi Metropolitan Protectorate and the Beiting Metropolitan Protectorate of the Tang Dynasty.

However, although the government offices have been set up, the actual situation, in the face of the vast land, Datang's local strength is far from enough.

There are only a few thousand soldiers and horses in the Standing Guard's Office.

If there is really something to do, I have to recruit the Hu people of the grassland to be servant soldiers.

And this route is the farthest, if you really want to go to Tibet from here, I'm afraid that it will take a year to be on the road.

The second route is to start from Chang'an in a straight line, go to Wuwei, jump over the Dafei River, enter Qinghai Lake, and go straight to the royal city of Tuyuhun.

As for the third route, it also starts from Chang'an, but with a lower arc.

Through Shuzhong, jump over the reckless mountains and mountains.

Hey, the difficulty of Shu Road is difficult to go to the sky.

If you really want to take this road, the cavalry of the Tang Dynasty will basically abandon their martial arts.

When you go over the mountains and mountains to the place, you don't mention the loss of the war horse, but I am afraid that the time on the road will take longer than the second road.

After crossing the mountains, we can continue to advance from the Chengdu Plain, pass through Xining in later generations, and reach Qinghai.

That is, the boundary of Tuyuhun.

"So Mr. Su, you see, although it seems to be vast, it is difficult for apes to cross and birds to fly in many places.

It is really difficult for the army to walk, and it is necessary to comprehensively consider logistics and supplies, water sources, and war horse movements, the length of the road, miasma, and the cold and hot climate. ”

Wang Xuance looked at Su Dawei, his eyes showing an inquiring look.

"Well, thanks to Dr. Wang's presence, and you are familiar with the terrain and veins over there, you can help me with a lot of advice."

Su Dawei nodded and said, "Let's continue to march according to the original plan." ”

According to the plan, this vanguard army will arrive in Wuwei first.

Whether it will be a direct military action or a seer of Pei Xingjian and Su Dingfang will depend on the specific situation.

It stands to reason that you should visit Su Dingfang first, after all, Su Dingfang is the head of the Logic Dao.

And Su Qingjie was also quite concerned about Su Dingfang's condition.

However, it is also necessary to see the situation at the time.

If there is a fighter, Su Dawei will not have many scruples, and he will definitely seize the fighter plane first and cut a wound on the Tubo people.

If there is cheap, there is no cheap, and it is necessary to create cheap.

Bloodlet the enemy until he is completely destroyed.

……

Hutian snowed in August.

The men and horses led by Su Dawei had only walked a short and half distance, and the climate was already very cold.

Even Su Dawei and Su Qingjie are fearless.

The soldiers below couldn't stand it either.

Every day people are attritioned because of frostbite and disease.

At the end of the first year of Lin De, Su Dawei had to be temporarily stationed in the place to prepare winter clothes and things to keep out the cold.

Second, he was waiting for more information.

This time he went to Chang'an, he asked Li Zhi's will to allow Ducha Temple to provide him with intelligence support.

It's just that Ducha Temple is now in the hands of the three Shaoqing, and it is far less convenient than when he was in power.

Fortunately, Su Da is in his hands, and he also has a team of people, who originally pulled some people from Ducha Temple and continued to keep them in the form of private parts.

Now it comes in handy.
