The next day, at dawn, 3,000 Tang Army soldiers and 5,000 Zhongyun soldiers in Datun City were waiting for battle.

In fact, Datun City has no danger to defend, and there was originally a moat, which was artificially lured.

The flood season has not yet come, so this moat has formed a decoration.

Fortunately, Datun City is several zhang high, and the city wall is also thick, so Li Hongding's heart is really stable.

When he learned that the Uighur army was coming, he began to set up defenses.

The Uighurs would certainly attack from the north, so he placed 1,000 Tang troops and 2,000 Zhongyun soldiers in the north.

In the other three directions, 500 Tang troops and 500 Zhongyun soldiers were arranged in each direction.

The remaining 2,000 troops were to be used as a reserve to reinforce in case of crisis.

He ordered the four gates to be sealed with cloth bags filled with sand and gravel, and even if the Uighurs hit them with wood, they would not want to break them open.

As a result, the Uighurs could only enter the city from the city walls.

blocked the way out, which also shows that Li Hongding has also made a posture of stubborn defense.

Li Hongding is only in his early thirties this year, and he is in the prime of life.

As the grandson of Zhang Yichao, the founder of the Guiyi Army, he is also quite proud.

It's a pity that the Guiyi Army has now disappeared, and to be precise, it has been integrated into the Anxi Metropolitan Protectorate.

Zhang Chengfeng, who was the heir to the Guiyi Army, was also transferred back to Chang'an.

There are various theories, but the Guiyi Army has indeed become history.

But the imperial court did not treat them badly, the descendants of the founders of the Guiyi Army, and they all got different positions.

Just like his eldest brother Li Hongyuan was transferred to the Anxi Metropolitan Protectorate, and several other people were also in the Anxi Metropolitan Protectorate, but they were not in the same place.

The intention of the imperial court is obvious, it does not want them to stay in Shazhou all the time, and would rather move farther away, but also weaken the sense of belonging of the Guiyi army, which is conducive to the rule of the imperial court.

If his father had been alive, it might have been different.

Realizing that he had such an unrealistic idea, Li Hongding shook his head, and soon he was alarmed by the sound of trumpets in the Uighur camp outside the city.

At this time, a lieutenant came to report, "Report to the general, the Uighur battalion outside the city is gathering a large army. ”

"I see, order the garrison to get ready!" Li Hongding commanded.

When the trumpet sounded in the Uighur camp outside the city, Qiuyun, the governor of Zhongyun's Governor's Mansion, couldn't help but find him again, obviously still a little worried.

For this Qiuyun, Li Hongding didn't know what to say.

In fact, with the grain, grass, cattle and sheep in Datun City, it is enough for the people in the city to eat for more than half a year, and there are millions of arrows, which are enough for a short time.

The lack of stones can demolish the houses in the city, no matter how you look at it, it is still no problem to hold on for a month or two.

You know, the Uighurs were not good at sieges.

。。。。。。

Outside Datun City, looking at Datun City in front of him, Harman can be described as a mixture of tastes.

Last time, he was defeated by the Tang Army here, so now he has no confidence to speak in the Khanate, and strength represents confidence.

"Hamman Agent, on your troops? Or is it on our Yanqi troops? Ibn looked at Haman with a frown and couldn't help laughing.

"Naturally, we are on the troops of Tongluo."

Seeing the contempt revealed in the other party's tone, Haman felt very uncomfortable.

"The cubs of the Tongluo Division, this time you must take Datun City for me and give us the blood shame of the Tongluo Division! Those who take Datun City will be rewarded with a thousand gold and sealed as a captain. ”

With the wave of Haman's sword, the first group of 3,000 soldiers to attack the city slowly advanced towards the city walls, pushing siege equipment and holding shields.

The sound of war drums kept sounding, and when they heard it, the morale of the attacking troops would be boosted, as if something had cheered them up, and the original fear would disappear.

At a distance of 150 paces from the wall, a part of the Uighur army halted its advance and began to immobilize a few large men.

These big guys are no strangers, they are trebuchets.

Although the Uighurs were a people on horseback, they were once powerful and it was not difficult to build trebuchets.

However, the range of trebuchets was not far, between 150 and 200 paces, and because of their complexity, the Uighurs only made these five trebuchets during this time.

But even if there are only five, the damage caused by trebuchets to the city walls is obvious, and the walls of Datun City cannot withstand it for too long.

When he saw the Uighurs pushing out the trebuchet, Li Hongding was aware of this situation.

However, when he saw that the trebuchet had stopped at a hundred and fifty paces, he felt much more settled.

He immediately waved his hand, "Bow and crossbow ready!" Aim for the Uighur trebuchets! ”

Soon, hundreds of crossbowmen formed a phalanx behind the walls, their arrows tilted at an angle to the sky, and then watched the standard-bearer's orders.

"Ready, put!"

Hundreds of soldiers fired at the same time, and hundreds of powerful crossbow arrows flew away, shooting at the enemy crowd from the front.

It was a commonly used crossbow with a range of up to two hundred and thirty paces, and it was so powerful that the armor-piercing arrows pierced through the shields, and a scream rang out, and dozens of Uighur soldiers were shot down and rolled to the ground.

More bolts were fired at the trebuchets as they prepared to fire stone projectiles, and before the soldiers could react, a large number of crossbow arrows turned them into hedgehogs.

However, this did not have much effect on the tall trebuchet, except that some crossbow arrows pierced the trebuchet's wooden frame, but failed to destroy the trebuchet.

Haman, who was commanding in the back, was naturally a little angry when he saw such a scene, and hurriedly asked the soldiers to hold their shields to protect the trebuchet.

Protected by several shields, the soldier who operated the trebuchet was well protected, and soon placed boulders weighing dozens of pounds in the throwing basket.

Soon five stone bullets flew towards the walls of Datun City.

"Boom, boom!"

Every stone bullet that hits the ground is a big pit, and if it hits someone, it can be smashed into a meatloaf.

Seeing the trebuchet in full swing, cheers were heard from among the attacking Uighur soldiers, and they ran faster.

With the help of such siege weapons, why should they not be able to break through Datun City.

The morale of the Uighur army was greatly increased, and the defenders in the city were a little panicked, especially those Zhongyun warriors, how had they ever seen such a big killing weapon.

Every time the boulder landed, it seemed to fall on their hearts, shaking the whole person's scalp and making his body weak.

"Commander Li, what now? If the Uighurs are allowed to fight like this, our walls will not be able to withstand it at all! ”

Qiu Yun began to get anxious, and every shock made him panic.

"Don't worry!"

Li Hongding calmed Qiu Yun, and his brows furrowed slightly when he saw that ordinary crossbow arrows could not threaten the bravious trebuchet.

"Order, let the crossbowman change for a rocket! Blow up that trebuchet for Ben Command! ”

"Yes!"

Soon, when the crossbowmen were notified, nearly half of them put away their bows and crossbows and assembled, while the remaining crossbowmen pulled away from each other.

Hundreds of soldiers came with special wooden boxes, and handed them to the crossbowmen with arrows tied to small bamboo tubes, all of whom were armed with fire ropes.

"Ready!"

"Ignition!".

"Shoot!"

After the order, more than a hundred spark-ridden crossbow arrows flew out of the air!
