In July of the seventh year of Xuanren, there was a serious civil strife in the Hui country, Tuoba Qianli led the army into the capital, announced the abolition of the loyal Khan, and set up a new Khan, which was supported by many Hui nobles loyal to the former Dengli Khan, under the serious crisis of governance, the loyal Khan who was far away from the Tang army in the north court was forced to be helpless, so the Tang army made peace, and the two sides finally reached an agreement in two days of negotiations, the loyal Khan recognized in writing that the North Court and Anxi belonged to the Tang Dynasty, and ordered the Jiegan gas of Anxi to lay down their arms and surrender to the Tang army, The Tang army promised that the Anxi Hui army could cross the border after laying down their weapons, and that they would return their weapons after they left Beiting.

At the same time, Zhang Huan also made it clear that he would support the return of the loyal Khan to the Khan, and the Tang army could provide assistance if necessary, at the end of July, the news of the Khan's peace with the Tang army had not yet reached Anxi, and the enemy's Jiegan gas was in order to open up the road to the north, and the Tang army fought a decisive battle north of Bosten Lake, but was defeated by the Tang army in the north and south, and the Hui southern expeditionary army was killed and wounded nearly half, a few days later, the order of the loyal Khan to lay down his arms was transmitted to Anxi, and the Jiegangas, who was exhausted of food and grass, was also in a hurry, so he surrendered to the Tang army.

The 40,000 Hui troops left the northwest of Anxi in three groups under the supervision of the Tang army, and finally joined the loyal khan at the Duoluo River north of Beiting, and the army returned to Mobei.

However, at the same time as the battle between the Tang army and the Hui army at Bosten Lake, the Tubo army, which was far away in Bachang City, began to march towards Qiuci, trying to drive the Tang army out of Anxi.

The vast savannah stretched out in all directions like a giant with its arms outstretched, the sky was endless blue, and the earth was shrouded in a hot blue dome. Several eagles soared in the sky, their eyes sharply staring at the ground armies of the earth.

Wang Siyu's cavalry can be called the elite of the Xiliang cavalry, some of them are veterans who captured Shibao City with Wang Siyu, the other part is the strong ones selected from the Han slaves who were liberated in Hehuang, and there are some Qiang cavalry, their biggest feature is that they are superb horsemanship. They could not get off the horse for several days and nights, and then under the cruel training of three years of lying on the salary and tasting courage, they not only mastered the fighting skills such as mounted archery and knife skills. And there is a strict organizational discipline, and every move is like a cloud. Jing is as dignified as a mountain, and it is precisely this elite cavalry that enables Wang Siyu to march day and night, and capture Yanqi and Qiuzi in one fell swoop.

As a commander, Wang Siyu inherited the spirit of his grandfather, Wang Zhonghei, the military god of the Tang Dynasty. He was loyal, resolute, and decisive, and he was sometimes like a sharp sword. Able to cut and kill with indomitable progress; Sometimes like a calm sea, there is a turbulent undercurrent under the calm sea level, he is only thirty years old this year, but he is already a veteran of many battles, calm and sharp.

A scout from afar galloped over and reported loudly: "General, the vanguard of the Tubo people is already twenty miles away, about 6,000 horsemen. ”

"I see. Revisit! ”

"Yes!" The scout saluted. Turning around, Wang Siyu beat the curtain and looked at the terrain on both sides. The White Horse River flows from the northwest, arcing in the distance and flowing in the northeast direction, like a longbow, meandering, and beside the river five miles away is a large forest.

Wang Siyu pondered for a moment, and then ordered Cao Hanchen, the commander of the first battalion, to say: "You can lead 3,000 troops to hide in the woods, and wait for the Tubo soldiers to pass and cover up from behind." ”

"The last general obeys!" With a wave of Cao Hanchen's hand, three thousand troops separated from the ranks and galloped north.

The Tang army slowed down the speed of the horse, tried to rest the horsepower, and moved forward for about three or four miles, at this time, more than a dozen cavalry appeared on a high ground in the northwest direction, which was the scout of the Tubo people, Wang Siyu immediately ordered, expand the banner, and create the momentum of 10,000 people, and then a patrol of 500 people chased and killed the Tubo scouts, and the Tubo scouts turned around and fled.

Wang Siyu waved his hand, five thousand cavalry immediately stopped moving forward, and stood still on the grassland, cavalry combat, in addition to the knight's own equipment and the sophistication of the horses, but also pay attention to momentum and tactics, with their own strengths, the enemy's shortcomings, the Tang Army's advantage is that it is well-equipped, not only equipped with long lances and horizontal knives, but also sharp bows and arrows, especially the Xiliang Army, they changed the traditional cavalry bow and arrow equipment to a hard crossbow, the soldiers are uniformly equipped with crossbows, the range can reach two hundred and thirty steps, and the effective killing distance is one hundred and fifty steps. The accuracy is far above the bow and arrow, the only disadvantage is the poor rate of fire and flexibility, for this reason, one of the most important training courses of the cavalry of the Xiliang Army is to ride and shoot at high speed, Wang Siyu's cavalry can all be skilled in the use of crossbow arrows.

The arrow is not an ordinary arrow, this time Wang Siyu is equipped with a special armor arrow to deal with the Tubo people, the arrow is pointed and cone-shaped, long and slender, and slotted on three sides, it is specially developed for the chain mail of the Tubo people.

In order to deal with the cavalry of the Tubo people, the Tang army also made a lot of other preparations, such as war horses, the characteristics of the war horses of the Tubo people are excellent weight bearing and endurance, suitable for long-distance trekking in the alpine region, but the horse speed is not fast, especially the lack of impact, and the Xiliang army is mainly equipped with Turkic horses, which are also durable, but the size is small, and the speed can not keep up. The limbs are slender, the control of the reins is extremely sensitive, the speed and explosiveness are extremely strong, but unfortunately there are not many such good horses, in the past few years, the entire Xiliang army has only more than 20,000 horses, of which 10,000 are matched in Zhang Huan's guards, and the other 10,000 are equipped in Wang Siyu's army.

The sky is high and vast, the west wind blows strongly, five thousand Tang cavalry divided into two legions standing on the vast prairie, this is a group of warriors who fight for the country and ideals, their blood is boiling, in order to wash away the shame of the weakness of the Tang Dynasty after the Anshi Rebellion, they came to the distant Western Regions thousands of miles away, fighting for the glory and interests of the Tang Dynasty.

In the distance, a black line appeared, and the five thousand cavalry vanguard of the Tubo people finally arrived at Qiuci after more than three hundred miles of day and night running, it should be said. Tri Song Detsen's strategy was correct, he ordered the Tibetan army to retreat westward, thus occupying the fisherman's position, but he did not expect that two things would happen, a Tang army would come from the south and occupy the Qiuzi that he had conceded. The second is that he did not expect that there would be civil strife in Hui, so that the inevitable large-scale and tragic battle ended in negotiation.

So. His strategic retreat turned into a strategic mistake, and he handed over Yanqi and Qiuzi to the Tang army in vain. For this reason, Trisong Dezan hated Zhang Huan very much, and when the Tang army was still fighting with the Hui army in Bohu, he personally led an army of 50,000 to pounce on Qiuzi, of which his 5,000 pioneers arrived on the bank of the White Horse River in only two days and two nights.

The pioneer general of the Tibetan region is called the Mang Zangbo. He was the son-in-law of Trisong Detsen, and he was very brave and fierce. When Tri Song Detsen was besieged by the Great Food Army in Tocharo, it was he who led the army to open a bloody road and rescue Zampu from danger, and his 5,000 subordinates were also professional soldiers, compared with those who were temporarily cobbled together by the herdsmen to put together the Tibetan army, they were more bloodthirsty and brave, and it was precisely in this way that they have always been the sharp knife of Trisong Dezan to open the way.

Compared with the Tang Army. The equipment of the Tibetan people is slightly inferior. Especially at the level of bows and arrows, they were far inferior to the Tang army. The equipment of cavalry and infantry is no different, mainly wearing chain mail, holding spears and round shields, and using traditional long swords in close combat, but their personal physique is very strong, endurance is long-lasting, and they rarely get sick, especially in the alpine regions, generally speaking, if the battle between the Tang army and the Tubo army falls into a stalemate, in the end, it is often the Tubo army that wins by virtue of the advantage of physical strength.

At this time, the Tang army also saw the Tang army in the distance, he waved his hand lightly, the army slowed down, he had already been rewarded, the Tang army was about 10,000 people in terms of momentum, but in fact it was similar to his own strength, only 5,000 people.

He smiled proudly and said: "Zampu has a saying, whoever takes Qiuci first can be crowned the king of Anxi, but he sent me as the vanguard, obviously he did not take me into account, brothers, if you can help me take Qiuci, you can use the women, cattle and sheep you see." ”

When the news broke, the 5,000 Tibetans let out a wolf-like howl, they were professional soldiers, who lived by plundering and killing, and in their eyes, the Tang army in the distance was nothing more than a flock of sheep to be slaughtered.

"Kill!" With a wave of the long sword of Mangzangbu and a wild roar, the Tubo army urged the war horse with both legs, raised the shield in the left hand and the spear in the right hand, and rushed towards the Tang army overwhelmingly, and the grassland was filled with a murderous aura that rushed to the sky.

The Tang army was as dignified as a mountain, they held a hard crossbow in their hands, and their fierce eyes looked at the rushing Tubo army, and the rear army began to trot backwards, about two miles out of the stop, so that the army was deployed on the grassland in two phalanxes.

The advantage of the Tang army lies in the crossbow arrows, for the cavalry crossbow arrows, the most famous is the wheel combat method, but he needs superb horse control skills and the strictest discipline, even if his companions are killed in front of him, he cannot mess up the formation, the principle of which is to shoot in three stages later.

The distance of several miles is only a flash for the Tubo army, five hundred steps, four hundred steps, two thousand Tang troops stand quietly on their horses, crossbow arrows are slowly raised, aiming at the front, their formation has been arranged, divided into five rows, each row of four hundred people, and the other left and right have five hundred people to suppress the position.

Two hundred steps and one hundred and fifty steps, the Tubo army has entered the effective killing distance, the sinister smile on their faces is already clearly visible, and the shield is raised, and they are not afraid of the Tang army's arrow array at all.

"Shoot!" The Tang army commander gave an order, the arrows rained down, the first row of crossbow arrows rose into the air, shot towards the Tubo army, despite the shield guard, the Tubo army that rushed to the front still fell a piece, the war horse neighed, flew out, the attack speed of the Tubo army immediately slowed down, the Tang army shot an arrow here, the first row of Tang troops immediately turned back, the second row of Tang army crossbow arrows has been issued, and then the second row of Tang army crossbow arrows also turned back, the third row of Tang army crossbow arrows have been shot, five rows later, the original first row of Tang army installed crossbow arrows, and so onThe Tang Army's war horses were agile and retreated extremely fast, only one point slower than the impact of the Tubo people.

Looking from afar, it seems that countless oval circles are rapidly rolling on the ground, only a few rounds, the Tubo army is less than fifty paces apart, the Tang army immediately stopped shooting, accelerated the speed of the horse, and instantly pulled away the Tubo people, they rushed to the rear army, and once again set up the camp.

With a swipe on the ground, the hard crossbow of the 2,000 Chinese army once again rose flat, and the tip of the arrow was coldly pointed at the enemy. The Tang army's rainstorm-like arrow array was extremely lethal, and in just a few hundred steps, the Tubo had killed and wounded thousands of people, and the morale and fighting spirit of the Tubo army had dropped significantly.

On Mangzangbo has also calmed down. He realized that if he pursued him like this, his army would be shot dead by the Tang army sooner or later. He shouted: "Stop! ”

The remaining 4,000 Tibetan troops suddenly stopped, and the two armies were a mile apart and looked across from each other on the grassland. The west wind blew strongly in the field, blowing their respective banners to the sound of hunting.

On Mang Zangbu suddenly gave an order, the four thousand Tubo troops immediately formed a huge and neat phalanx, hundreds of Tubo cavalry holding huge shields in front of the front, and the Tubo army behind each holding a round shield. Densely packed together, it actually formed a shield mountain. It's not fast, dada! The land was pressed towards the Tang army.

This is also the Tubo people and the Tang army in a hundred years of war summed up, specifically to deal with the Tang army bow and arrow methods, the original infantry formation, coupled with sharp cavalry impact, and now also used for cavalry, although the most powerful impact of the Tubo cavalry is gone, but the number of deaths has also dropped significantly.

As the Tibetans gradually approached, the Tang army also merged into one place. Five thousand Tang troops remained motionless. As dignified as a mountain, Wang Siyu stared coldly at the Tubo people. The large iron spear in his hand was already horizontal, and he took out a demonic bronze mask and put it on his face.

Gradually, the Tubo army reached the effective firing range again, the Tang army still did not move, a hundred steps, suddenly, the Tang army erupted with an earth-shattering roar, two thousand cavalry killed like thunder, and the murderous aura in the sky even changed color in shock.

Rumble! With a bang, like a huge wave colliding, the sharp Tang army instantly tore open the cavalry formation of the Tubo people, Wang Siyu took the lead, he waved a 150-pound big iron gun, roared, a shot pierced the chest of five or six Tubo cavalry, the big gun was flicked, accompanied by a long scream, the five or six Tubo people on the gun were thrown out.

Wang Siyu's wildness suddenly attacked, his big iron spear flew up and down, sometimes like a pear blossom rainstorm, sometimes it seemed to be a thousand horses, killing the Tubo soldiers on their backs, killing and wounded, his war horse was unusually tall and powerful, walking vigorously, like a cloud driving the fog, with his majestic figure, and a big iron gun, and then his devilish face, so that the Tubo soldiers were frightened, seeing him killing, they all shouted, ran to both sides, for a while, Wang Siyu was like a tiger like a flock of sheep.

Seeing that Wang Siyu was invincible, he couldn't help but be furious, and swung his spear at him, Wang Siyu caught a glimpse, he smiled coldly, shouted, and then the Tang army blew a low horn, and the five thousand Tang troops turned their horses' heads and galloped eastward like a storm.

"Give me chase!"

On the Mang Zangbu was played by the Tang army between applause, he was so angry that he went crazy, roared and chased after the Tang army, in a moment, the two armies had run five or six miles away, had rushed through a large forest, the Tang army suddenly stopped, they quickly lined up, skillfully loaded crossbow arrows, waiting for the Tubo people to approach.

At this time, Wang Siyu galloped in front of the cavalry formation, and his vague and high-pitched voice sounded in front of the formation: "Put away the crossbow, pull out your war knife, the shame of your father will be washed away with the blood of the Tubo people, the Tang Dynasty will remember you, and thousands of Tang people will be proud of you, now is the time for you to fight for the Tang nation, let the Tubo people taste the iron blood and blade of our Tang cavalry!" ”

His knife swung forward, and he shouted, "Kill!" ”

"Kill!"

The blood of the five thousand cavalry began to boil, since ancient times, the unity of the country and the strength of the great country can only be achieved in iron and blood, begging and weakness will only bring more humiliation and shame, the strength of the Han lies in its momentum of swallowing thousands of miles like a tiger, and the strength of the Tang Dynasty lies in the fact that it has the mind of accepting all rivers and the iron-blooded military exploits.

The five thousand Tang cavalry were like an unsheathed sword, swept away against the Tubo army, and the two armies finally collided in the most direct and tragic way.

Swords clashed against swords, slashing into human bones, moans of men, and terrible gurgling of the dying.

Wang Siyu galloped in the Tubo army, he was killing and invincible, he and his five hundred guards were like an iron fist, where he passed, the formation of the Tubo army collapsed one after another, the heads rolled down, killing through the dense human walls, he was looking for the leader of the Tubo army.

Seeing it, the Zangbu brandished a spear and stabbed at him from the oblique thorn, roaring like thunder, but before the spear approached, he suddenly felt that he had soared into the air, he saw the blue sky, the sun was so dazzling, he couldn't open his eyes, the strength of his body had disappeared in an instant, Wang Siyu's spear pierced his neck, and raised him high like a flag.

The Tang army suddenly thundered with joy, and the enemy chief died! The enemy chief is dead! The morale of the Tang army was greatly boosted, while the fighting spirit of the Tubo army was low and the people were panicked.

At this moment, a new force suddenly came out of the forest, covering from behind the Tibetan army, and the Tibetan army was attacked by the enemy, and the will to resist collapsed in an instant, and began to rout westward.

Wang Siyu saw that the victory was decided, and he immediately coldly ordered: "Chase and kill to the end, and do not accept surrender!" ”

In August of the seventh year of Xuanren, Wang Siyu personally led 8,000 cavalry to annihilate all the 5,000 vanguard of the Tubo people on the bank of the Baima River, beheaded more than 4,700 people, only less than 300 people escaped, Trisong Dezan heard that the vanguard was defeated, he immediately urged 40,000 troops to kill Qiuci, at the same time, Xin Lang's 40,000 troops also arrived at Qiuci one day earlier, the Tang army took a defensive position, avoided without fighting, the two armies then confronted each other in Qiuci, on August 10, Zhang Huan personally led 50,000 troops to arrive in Qiuci.
