Li Shimin was afraid that it would affect his beloved wife's mood and recuperation, so he did not inform Xia Xue of Tubo's wanton invasion of the Tang Dynasty and the defeat of the "Battle of Dafeichuan" this year, but continued to command Tang. The army counterattacked.

Tang Taizong Li Shimin ordered Li Jingxuan to be the general manager of the Taohe River march, the ambassador of Xihe Zhenfu, and the governor of Shanzhou, and Liu Xianli, the secretary of the Ministry of Industry and the general of the Left Guard, as the Sima of the Taohe Road march, and led the army to attack. In addition, the governor of Yiyi, Shi Li Xiaoyi, and the governor of Minzhou, Wang Fengyi, mobilized troops from Jiannan Province (Chengdu, Sichuan) and other places to cooperate in the battle.

The Tang Dynasty approached Tibet with 180,000 soldiers and horses, which was unprecedented. When Tubo heard the news, he took the famous general Gar. Qinling supervised the troops and was ready to fight.

In May, the two sides fought at Longzhi (later known as Ledunan, Qinghai). Tang Dynasty. The general Zhang Qianqiao led the elite soldiers and won two battles in one day. The Tibetan army was defeated and retreated for hundreds of miles.

Tang Dynasty. The army attacked rashly, and Liu Xianli led the front team to go deep and stationed troops in Hao. Gar. Qinling highlighted the strange soldiers and stormed Liu Xianli.

Liu Xianli led the army to the enemy, but was outnumbered and failed to break through the encirclement. As the commander-in-chief, Li Jingxuan was cowardly and afraid of war, and did not move his troops in order to protect himself. Liu Xianli was defeated and captured.

When Li Jingxuan heard the news, he immediately led his troops to flee to Chengfengling (Qianhuzhuang in the southwest of Xining, Qinghai in later generations), and used the mud ditch to cover and defend it. The Tubo army occupied the commanding heights, and Li Jingxuan had nothing to do, so his troops sat and waited to be killed.

Tang Zuo's leading general, Hei Zhi Changzhi, did not want to sit idly by, and personally led 500 masked death squad "ghost face riders" to attack the Tubo camp at night.

When a group of ghost-faced horsemen appeared in the Tibetan military camp, when the Tubo soldiers saw the blue-faced and fanged "ghost-faced horseman" soldiers, their first reaction was not to step forward to fight, but instinctively chose to retreat, because the appearance of the "ghost-faced horseman" soldiers was indeed terrifying, with hideous appearances, bloody long knives, pitch-black armor and neighing war horses.

"Ahh

"Devil!" Many Tibetan soldiers shouted this, but before they could finish their words, the long knives of the "Ghost Rider" soldiers had already cut off their heads.

Hei Tooth Changzhi's blood was already boiling, and in the face of the Tubo soldiers who fell into chaos in front of him, Black Tooth Changzhi decisively gave the order to slaughter.

Originally, Hei Zhi Changzhi only wanted to burn Tubo's camp tent to create chaos, but he didn't expect that Tubo's camp would be so loose because of the light enemy, which gave Hei Zhi Changzhi a chance to slaughter.

"Kill-" Hei Fang Chang Zhi led 500 death squads to continue to slaughter in the Tubo camp, when the Tubo cavalry who hurried to the rescue saw the opposite ghost horse, their hearts suddenly trembled, they were shocked, and were suppressed by Black Tooth Changzhi and his ghost face horse.

The bronze mask seemed to be half-alive under the light of the raging fire at night, revealing its greedy and bloodthirsty nature, plus the bronze mask was stained with scarlet blood, and when hundreds of "ghost-faced riders" rushed towards the Tubo spirit horse, the ghost-faced horsemen seen by the Tubo cavalry were like demons from hell, which made them have no courage to resist in their hearts.

"Run—" was their only thought right now.

When the Tubo general saw the formation of the ghost-faced horseman, he was also a little worried, and when he saw that the black tooth Changzhi was killing him, he hesitated in his heart and chose to escape.

And this just gave the opportunity for the ghost face of the black tooth Changzhi to slaughter, 500 people chased and killed more than 5,000 people, this scene was staged in the Tibetan military camp and completely hit the morale of the Tibetan soldiers, many of them who wanted to resist when they saw this scene when they decisively gave up the idea of fighting, and the only thought in their hearts was: "Run-run!" ”

The entire battalion is now the world of the "ghost-faced riders" of the black-toothed death squad, and the entire battalion has become their slaughterhouse.

The Tubo army did not expect this move, and suddenly there was chaos, with more than 2,000 dead and wounded, and the general set up a hurry to lead the army to flee for his life.

Napoleon said a classic saying about war: "The principle of war is the same as that of siege, fire must be concentrated at one point, and a gap must be opened, and once the stability of the enemy is broken, the task is to crush it completely." "This black-toothed man, who did not know why Napoleon, was a natural tactician, and in the field of warfare, theory is pale, and rich practice of war is important.

Li Jingxuan began to lead the army to return to Shanzhou (Ledu, Qinghai). Li Shimin, Taizong of the Tang Dynasty, promoted him to the deputy envoy of the Heyuan Army with his "black teeth and constant skills."

Hei Zhi Chang Zhi is a native of the western part of Baekje, the Black Tooth clan, more than seven feet tall, good at using soldiers, brave and strategic.

Heizhi Changzhi once led 200 Tang soldiers to defeat more than 3,000 Tibetan soldiers.

It is said that that time, the Tubo army dui, along the border line, robbed all the way, quite smoothly, the army of the Tang Dynasty dui, can only follow behind, there is no way, in order to catch up with the speed, the black tooth Changzhi only brought two hundred cavalry.

In the eastern part of Qinghai, Heizhi Changzhi and a Tibetan army that had just returned from looting had met each other.

The number of Tubo troops encountered by Hei Tooth Chang Zhi was relatively large compared to his own 200 people, there were more than 3,000 people, after seeing Hei Tooth Changzhi, this group of Tubo soldiers, because they were immediately carrying a large amount of looted property, did not want to trouble unloading it, and saw Tang. There are only 200 people in the army, and they are very contemptuous, so they decided to get off the horse and directly clean up this handful of Tang. Army.

This group of 3,000 Tubo troops all dismounted, toothless tigers, what is there to be afraid of, seeing that the Tubo soldiers gave up their advantages, did not ride horses, and planned to fight with their own positions.

Hei Tooth Changzhi didn't think about it, he directly commanded his two hundred cavalry, rushed to this group of Tubo soldiers, a few back and forth, Tubo's formation was all messed up, and those who didn't die could only throw away the looted property, ride a horse, and run back to find the main force.

Before leaving, he left a sentence: If you don't go, I'll find someone.

In the evening, the main force of Tubo really came, but when they saw the formation on the side of the Tang Dynasty, they didn't dare to fight, and they hesitated for a while, so they could only pack up, pack the things they had grabbed, and go back.

What's going on?

After all, there were only 200 people in Heizhi Changzhi, and the other main forces did not come, so he called people to use the trophies dropped by the Tubo soldiers to place a large number of torches in the distance and on the left and right. Good guys, such a big formation, there are more people than ours, you can't fight, retreat.

In June 642, the Tibetans again attacked Weiyuan. Tang Taizong Li Shimin issued an edict to personally recruit more than 100,000 troops and 40,000 horses. On the tenth day of the first month, Xue Ne led a large army to Wujieyi to fight against the Tubo army. Wang Hui, the herd envoy of Longyou, led 2,000 soldiers and horses to attack the mouth of Dalai Valley, 20 miles away, and cooperated with Xue Ne's army. The Tibetan general Kun Dayan stationed 100,000 soldiers and horses here.

Wang Hui selected 700 warriors to wear Tibetan costumes, divided into two teams, front and rear, and attacked the Tibetan army at night. The front team went to the camp and shouted, while the rear team five miles away cheered with drums and horns.

The Tibetan army thought that Tang. The main force of the army arrived, and in panic, they killed each other, and more than 10,000 people died.

After Wang Hui led the army to victory, he immediately waved his troops to fight on the street. Once again, a strong man was selected to attack the Tibetan army at night. The Tibetan army was in chaos, and Xue Ne also led his troops to kill, attacking before and after, and defeated the Tibetan army.

Tang Dynasty. The army took advantage of the victory to chase and kill to Taoshui, resumed the battle in the long castle, defeated the Tubo army, beheaded 17,000, and intercepted 1.2 million cattle and sheep.

Seeing that there was no way to retreat, the Tubo army swore to fight to the death, and surrounded Wang Haibin in the vanguard of the Xue Ne army and the right guard of the prince's right guard, and the Tang generals were jealous of their military exploits and did not send reinforcements for a long time, and finally died on the battlefield.

After Xue Ne led the army to arrive, the whole army of Tubo had been annihilated, the corpses were all over the field, the water did not flow, and the Tibetan general Liuzhi Township Mihong was captured. Tang Dynasty. The army killed tens of thousands of Tubo troops before and after, and they plundered all the sheep and horses.

At the beginning of July 642, after the Tubo army occupied Shibao City, which was under the jurisdiction of the Tang Dynasty, it sent heavy troops to guard it, and used it as an outpost position, repeatedly showing troops to attack Tang Hexi, Longyou and other areas. The Tang Dynasty regarded it as a problem for its henchmen.

Tang Taizong Li Shimin ordered Shuo Fang Jiedu envoy, Xin'an King Li Yi and Hexi, Longyou garrison generals to discuss the siege plan. However, all the generals proposed that the stone fort should be considered in the long run, on the grounds that the stone fort is far away and the terrain is dangerous, easy to defend and difficult to attack, and the lone army is deep and afraid of being destroyed.

Li Yan thought that the geographical location of Shibao City was very important, and it must be recaptured as soon as possible, although it was dangerous, he did not hesitate to sacrifice his life for the country. On July 16, Li Yi boldly adopted long-distance attack tactics and killed Benshibao City day and night. The officers and soldiers defending the city of Tubo were caught off guard, and there were many casualties, and the stone fort city fell to Tang again. The Hand of the Army.
