There is nothing special about the tactics of dealing with cavalry, and the three main treasures of Mo knife, bow and crossbow, and the moon array, Hu Tianke has all tried them. Although due to the terrain and environment, the arrangement did not bring the things needed for the moon array, but the other two were all around. Therefore, as soon as the war began, the Liang army was greeted by the dense bows and crossbows and arrows, and they were completely stunned.

Finally waited until the arrows no longer appeared, and before they had time to be happy, the fierce Mo Dao appeared in front of them again, and those elite Tang Army cavalry were killed together.

In the battle outside Guzang City, Hu Tian and Sun Tie cooperated tacitly, and one was responsible for attacking from the front and destroying the enemy army from the inside out. The other is to attack from the periphery and strip the Liang army layer by layer.

The battle lasted only one morning before it was officially declared over, and Hu Tian and Sun Tie beheaded 50,000 and captured more than 30,000. The rest were either dead or wounded, and only a small fraction of those who escaped.

Especially Zhang Xuanliang and other important ministers of the Liangzhou clan, a large part of them died or were captured with Zhang Xuanliang in this battle. At this point, the main forces of Liangzhou have been basically wiped out.

Even if there are still some local forces left, they can no longer pose the slightest threat to the Tang army, which occupies an absolutely dominant position.

After the end of the war, Hu Tian left some men and horses to guard Guzang City. Then, he and Sun Tiebing split up and began to sweep the entire Hexi Corridor.

Among them, Sun Tie led the cavalry to quickly go north and rushed to Dunhuang County, the westernmost part of the Hexi Corridor, to first grasp the dangerous places of entering and exiting the Western Regions, Yumen Pass and Yangguan. Hu Tian himself, on the other hand, led the army under his command to clean up the surrounding three counties of Jiuquan, Zhangye and Wuwei, and took all the county seats.

By mid-September, the Hexi Corridor had been completely settled. At this time, the town army mobilized from Jincheng, Qinzhou, Lingzhou, Shuofang and other places had already taken over the defense of the Hexi Corridor.

After receiving sufficient supplements, Hu Tian and Sun Tie officially led an army of 50,000 people out of Yumen Pass and marched towards the Western Regions.

When the countries in the Western Regions heard that the Tang Dynasty soldiers and horses had been killed, they had their own thoughts, and some small countries chose to take refuge in the Tang Army, and took the initiative to guide the Tang Army deep into the territory of the Western Regions. For example, King Shanshan and King Cheshi, who had gone to Chang'an to pay tribute to the Tang Dynasty before, were originally in awe of the Central Plains Dynasty, so they were willing to submit.

And some countries were hostile to the Tang army and secretly united to prepare to resist the Tang army. Among them, the most resolute is the Qiuzi Kingdom, which united more than 30 small countries in the Western Regions and gathered more than 700,000 troops to prepare for a decisive battle with the Tang Dynasty.

But this news was heard by the staff in advance, and after Hu Tian, who got the news, heard about it, after discussing it with Sun Tie, he finally decided to finish the battle and expose his position, so as to attract the Western Regions Alliance to attack him.

At the beginning of October, the Tang army led by Hu Tian and Sun Tie confronted the Western Regions coalition forces such as Qiuci, Wensuguo, and Weitouguo at Beipiao, south of Qiuci, which later became the bank of the Tarim River.

In the battle, Hu Tian adopted the tactics of the Moon Formation, and lined up the 40,000 troops near the river to resist the cavalry attack of the Western Regions Alliance. Secretly, the 10,000 cavalry led by Sun Tie was quietly arranged in the poplar forest dozens of miles away from the battlefield.

The Western Regions Coalition is huge in size and numerous, but they are not subordinate to each other, and even quarrel with each other over offensive and defensive matters. In Hu Tian's view, such an army is actually just a rabble.

He refused to stand still with the Moon Formation, killing from early morning to evening, and remained immobile in the face of waves of attacks from the Western Regions Alliance. And under the defense of the Moon Array, the Western Regions Alliance Army just dropped a corpse on the battlefield.

Moreover, with a large army, the 40,000-strong Tang army could not be quickly wiped out, which was a serious blow to the morale of the Western Regions Alliance.

The decisive battle took place at night. That night, Sun Tie, who had been in ambush for a day, led 10,000 cavalry from the poplar forest to the edge of the battlefield, launched an arrow-shaped charging formation, and launched an attack several miles away from the Western Regions Alliance.

The Western Regions Alliance, which had all its attention on the tens of thousands of Tang troops in front, had long been exhausted from a day's attack and waiting, and at this time, it was the time when their spirits were at their worst. Sun Tie's sudden attack immediately caused chaos in the entire coalition army.

At this time, Hu Tian, who had been guarding for a day, also ordered a counteroffensive, and tens of thousands of troops rushed towards the coalition army.

After a night of killing, corpses were lying on the banks of the North River, and countless dead and wounded were killed. The battlefield was full of wails, and the horses and camels that had lost their masters stood blankly on the battlefield. After this battle, the Tang army killed more than 100,000 enemy troops, and most of the rest fled at night, and those who did not run away were just some foot soldiers.

More than 700,000 allied troops completely collapsed, and along with it, the resistance and hostility of the countries in the Western Regions were also disintegrated.

After the battle ended the next day, Hu Tian did not care about the fatigue of the army, and immediately ordered to march to the city of Qiuzi. The frightened princes and people of Qiuci were already frightened, and without saying a word, they tied up the king of Qiuci, and then opened the city gate and surrendered to the Tang army.

After the march was much smoother, Hu Tian replenished a large amount of supplies in Qiuzi City, and then used those war horses and camels captured from the battlefield to quickly march and sweep away the other small countries.

Finally, at the end of October, the entire Western Regions was completely pacified.

So far, the land area of Datang has almost doubled, and the population has also increased greatly. The most important thing is that mastering this important trade route in the Western Regions is a very beneficial thing for the entire Tang Dynasty.

Before the war with Liangzhou, there were still some objections in the imperial court, mainly because they felt that this Liangzhou was rich and rich, and it was not as easy to defeat as Qiu Chi. Who would have thought that a huge Liangzhou would be like a papier-mâché tiger, and it would be so unbeaten!

Liangzhou was pacified in a short period of time, which naturally brought Datang's prestige to a new level. For the people of the Tang Dynasty, it seems that the Tang army is invincible, which is beyond doubt. On the other hand, if there is a failure, it is really unexpected.

Compared with the glory and pride of the people of the Tang Dynasty, the remaining forces, such as the people of Yan and Jiangzuo, were a little uneasy at this time. After all, Liangzhou was wiped out by Datang so quickly, and if he really did it on his side, it seemed that he wouldn't be able to support it for too long!
