In the twenty-first year of Zhenguan, in June, after several years of recuperation and recuperation on the snowy plateau, Tubo Zanpu Songtsen Gampo and the Great Minister Geerdong agreed to work together to make Tubo stronger and stronger, because they deeply remembered the shame brought to them by the Tang Dynasty, and the shame was a very powerful driving force for some people.

When they learned that Li Hao was demoted to Qiongnan, Songtsen Gampo and Ge Dongzan were very happy, Li Shimin's stupid behavior of self-destruction of the Great Wall also stimulated their desire for revenge, that's right, for them, Li Hao is like a Great Wall protected around the Tang Dynasty, like a moat, insurmountable, but this moat does not exist now, can they not be excited, they have endured it for so long, and finally feel that the time is ripe.

On the sixth day of the sixth month of June, Songtsen Gampo recruited 150,000 troops, personally killed Princess Gaoyang to sacrifice the flag, and swore an oath to launch a war of annihilation against the Tang Dynasty, never to the death, and the commander of the 15th army this time is not as handsome as the left, not as handsome as the middle, nor as handsome as the right, but Ge Dongzan, the great minister of Tubo.

Ge Erdonzan has studied the art of war in the past few years, and carefully studied Li Hao's many combat cases, which can be described as well-prepared, this time it is not said that there is no Li Hao in the Tang Dynasty, even if Li Hao is there, he is not afraid, he is a little excited, he even hopes that Li Hao can come, so that he can be ashamed and see if this so-called Tubo nemesis can really restrain him.

Ge Dong Zan is the Tubo Zhixing, even if he has only practiced the art of war for three years, he has reached the realm of supernatural transformation, he did not pass through Gansong Ridge this time, but sent troops to Tuyuhun, and directly blocked the three major roads of Tuyuhun east, south and north to prevent news from leaking.

Tuyuhun King Nuo Ge Bo has already been frightened by the 150,000 Tubo army, and hurried out of the city to surrender, the barbarism of the Tubo people, he knows, if he does not surrender, I am afraid that Tuyuhun will not be left behind.

Geerdongzan took Tuyuhun as a springboard, bypassed Chiling, with lightning speed, within three days of Lianke Shibao City, Dafeichuan, Langzhou, three days later, and captured Shanzhou, the Tubo army was barbaric, after entering the city, burning, killing and looting, all kinds of evil, the broken city, like hell on earth, the people of the Tang Dynasty suffered a catastrophe.

Ge Erdonzan has obtained the essence of the art of war, and knows the truth of the speed of soldiers, he sent the right such as Shuai Lun Zhuren to increase the rate of 50,000 elite cavalry, surprise attack Lanzhou, and at the same time bring 100,000 troops to attack Huizhou.

When Ge Dongzan captured Shanzhou, Li Shimin received an urgent military report from the Tibetan attack, Li Shimin was shocked, and ordered Cheng Zhijie, Su Dingfang, Qin Huaiyu, Wei Chi Baolin and others to lead 100,000 troops, and sent troops in three ways to resist the Tubo army.

Cheng Zhijie and Su Dingfang are both battle-hardened generals, Qin Huaiyu and Wei Chi Baolin are also deeply inherited from their fathers, and they shined in the battle against Goguryeo, and they are the most outstanding people in the younger generation except for Li Hao, and Li Shimin is very optimistic about them.

However, Li Shimin was negligent, the opponent they faced this time was not an ordinary person, but Geerdongzan of Zhiguan Tubo, Geerdongzan has never fought unprepared battles, he has already sent scouts to go deep into the direction of Chang'an to spy on the military situation, as soon as there is a movement, send an eagle falcon message, the Tubo people are good at training eagle falcons, with this message, it is absolutely unthinkable for the Tang people.

When he learned that it was Su Dingzhi and two young generals who led the army, Ge Erdongzan in the tooth tent snorted coldly: "I didn't send Li Ji, hmph, Li Shimin is too underestimated to be true, but it's okay, this prime minister will make you pay a heavy price for this!" ”

Geerdongzan did not change the battle plan, after capturing Huizhou, he went to attack Taiyuan, and when he was less than sixty miles away from Taiyuan, Su Dingfang's 40,000 army and Cheng Zhijie's 40,000 army suddenly appeared, and attacked the Tubo army from the east and southeast.

Cheng Zhijie thought that he would be able to succeed in this surprise attack, and the north was Taiyuan City, and the Tubo army would have no way to escape, but what he didn't expect was that Geerdongzan didn't flee at all, he seemed to have been prepared, and directly led the army to fight with them, and then, Lunzhu Renzeng suddenly appeared from the south with another 50,000 Tubo troops, and came over, Cheng Zhijie and Su Dingfang's 80,000 troops were actually ambushed by Geerdongzan.

When the governor of Taiyuan heard the news, he hurriedly sent troops to support, and Qin Huaiyu and Wei Chi Baolin, who originally wanted to go around to the west to ambush Ge Erdongzan, also hurriedly led 20,000 troops to come to help.

However, when the Taiyuan army joined up with the army of Su Dingfang and Cheng Zhijie and attacked Geerdongzan, suddenly a fast horse came with a military report that Taiyuan had fallen and was captured by a surprise attack by Goddaman with 20,000 troops in Tibet.

Everyone was shocked instantly, Taiyuan is not an ordinary city, in Guanzhong, in addition to Chang'an, Taiyuan is the richest and most prosperous, hundreds of thousands of people in the city, because it is the land of the dragon of Gaozu Li Yuan, this is only one day, it was actually captured by Tubo, I have to say, Ge Dongzan's trick is really beautiful.

As soon as he learned that Taiyuan had been successful, Ge Dongzan immediately retreated and led the army to Taiyuan, Su Dingfang and Cheng Zhijie combined, knowing that the pursuit would not have any effect, so they could only lead the troops to retreat to Jingzhou, and then report to Li Shimin.

When Li Shimin heard that Taiyuan was lost, he was furious, and directly overturned the dragon case, and then covered his chest and fell on the seat, his face was pale, his expression was painful, and then he fainted.

After Li Shimin woke up, his body was very weak, but he still held his weak body to convene the ministers and discuss countermeasures, and finally, Li Shimin ordered Li Ji to lead 50,000 troops, together with Su Dingzhi Zhijie and others, to recapture Taiyuan, Taiyuan is of extraordinary significance to their old Li family, and must not fall into the hands of the Tibetan barbarians.

Since Li Hao left, looking at the entire court, in terms of military talent, Li Ji said second, no one dared to call it first, with Li Ji out of the horse, the ministers felt a lot more at ease.

Li Ji led the army all the way to Jingzhou, met with Su Dingzhi Jie, discussed the strategy, and began to send troops to attack Taiyuan.

In order to recapture Taiyuan, Li Ji implemented the conventional method of encircling three ques and one fight, but Tubo had 150,000 people to defend the city, and the high walls of Taiyuan City were thick, and the Tang army was only 150,000.

In fact, the siege was just a cover for Li Ji, he was waiting, waiting for Geerdong Zanlang.

Anyone who has played competitive games knows that once some people have an advantage in playing games, they will make all kinds of waves and feel invincible in the world, and such people, if they encounter a sinking opponent, they will often be overturned, so Li Ji is waiting for Geerdong to praise the waves.

On the night of the fourth day, Gerdonzan really waved, and sent Goddalman to lead 100,000 troops out of the city to attack Cheng Zhijie's camp at night, Li Ji had already waited for a long time, and immediately sent troops to start attacking the city, and did not send troops to help Cheng Zhijie at all, because he had already explained to Cheng Zhijie that if the enemy attacked at night, he tried his best to delay it and buy him the opportunity to attack the city.

The siege equipment of the Tang Dynasty was relatively strong, and under a strong attack, the 50,000 Tubo troops in the city could not resist, and finally broke through the southern gate.

As soon as the city gate is broken, the army pours into the city gate, enters the urn city, continues to break the door, as long as the urn city gate is broken, Taiyuan can be captured, the battle situation is too tragic, only half an hour, the Tang army has been killed and wounded more than 10,000.

However, just when Li Ji was commanding the broken urn city, a large army suddenly arrived in the south, and it was Godardman's 100,000 army, they actually got rid of Cheng Zhijie's army and came to help, Li Ji was shocked, this Cheng Zhijie was too incompetent.

Cheng Zhijie is also very wronged, he has always been in accordance with Li Ji's orders, with this 100,000 army to fight and retreat, after all, there are many people on the other side, he can't beat it, just act according to Li Ji's plan and drag it down.

However, this 100,000 army was originally a chess piece under Geerdonzanbu, in order to attract the Tang army to attack the city, and then the army in the city pretended to be invincible, so that the Tang army broke through the city gate and entered the urn city.

At this moment, there are at least 70,000 Tang troops in the urn city, blocked by Godardman's 100,000 army, unable to get out, and want to continue to attack, but the arrows at the head of the city are raining, and the Tubo army also used fire oil and began to set fire to the urn city, and the Tang Dynasty is experiencing the worst defeat in 20 years.

Fortunately, Cheng Zhijie's 50,000 troops also rushed to help, and forcibly tore a hole in Godardman's 100,000 army, and rescued Li Ji, Su Dingfang and other main forces, as for the other 100,000 troops, they were all buried in Taiyuan.

How could Ge Erdongzan let them escape, pursued all the way, and finally Li Ji and they were defeated and fled into Jingzhou, and they could not hold out, and there were only 40,000 left in the fifteenth army.

Ge Erdongzan did not entangle with Li Ji and them, bypassed Jingzhou, directly led the army all the way to the southeast, met the city and captured the city, unstoppable, pointed directly at Chang'an, Li Shimin, who was in Chang'an, heard the news of Li Ji's defeat, his face was as white as paper, and his already weak body was even worse, and he fell ill again.

Now Chang'an has less than 50,000 troops, seeing that the Tubo army will soon be in the city, the whole Chang'an is panicked, and a large number of people and wealthy businessmen have begun to flee to Chang'an, after all, Tubo is coming to Chang'an, and they must flee Chang'an.

And above the court, the ministers are also worried, after all, the Tubo army, now the emperor is in poor health, no one presides over the overall situation, the most terrible thing is that there is no available general in the court, even Li Ji has been defeated, who else can stop Geerdongzan's troops.

Just when Geerdongzan was attacking Chang'an, Li Hao, who was in Qiongnan, received Shi Najie's flying pigeon message, detailing the battle of Tubo's troops and Li Ji's defeat.

After Li Hao read the letter in the study, he casually burned the note, watching the note turn into ashes, Li Hao got up slowly, and sighed loudly: "The opportunity has finally come, it's a pity...... This opportunity has sacrificed how many people and the hot-blooded sons of Datang. ”
