Cao Zhen frowned, carefully observing the changes in the situation on the entire battlefield.

Today's situation is different from yesterday, from the very beginning of the battle, Cao Zhen understood that he would definitely be at a disadvantage.

After all, yesterday he was the superior side in terms of troops, and today he is the side with the inferior forces.

But because of this, Cao Zhen made some adjustments to his 15,000 soldiers.

Among the 35,000 Wei troops, there were about 5,000 archers, and Cao Zhen assigned 3,000 people to Wang Chang, so that when he led the troops to attack Tongguan, he could cause arrows to suppress the city, and the remaining 2,000 lunges, Cao Zhen handed over all the defense lines on the right flank commanded by Dai Ling, and also gave Dai Ling 4,000 soldiers, a total of 6,000 people, to block the impact of nearly 4,000 cavalry.

There is no way, the threat of cavalry is too great, even if two thousand archers are given, and four thousand infantry are equipped with a thousand pikemen, it is still difficult to inflict effective damage on the cavalry troops, and it can only be said that in a defensive battle, it can hold out for a longer time.

As for the remaining 9,000 infantry, Cao Zhen's central army arranged 5,000 people, and the left flank arranged 4,000 people, and Cao Zhen commanded the defense.

Among the 9,000 soldiers here, there is not a single archer, so it is impossible to effectively suppress the attacking Shu thieves, and it is necessary to choose hand-to-hand combat to prevent the Shu thieves' archers from killing and injuring.

Therefore, from the very beginning of the battle, the battle between the middle and the left flank went directly into hand-to-hand combat.

Cao Zhen was under a lot of pressure, after all, he was dealing with an attack of 20,000 with 9,000 people.

If it weren't for the fact that Zhang Xi's command on the middle side seemed to have some problems, and the offensive coordination was very jerky, I'm afraid Cao Zhen would not be able to withstand the pressure now.

But the attack on the left flank of the Wei army was very fierce.

The left flank line of defense was fiercely attacked by Shu thieves.

At the beginning, the development of the battle situation was not bad, the quality of the soldiers of the Shu thieves was uneven, the Yongzhou soldiers were very good at military array operations, and they could make up for some of the lack of combat power through the cooperation of the military formation, and although the new reinforcements looked brave, the military formation coordination ability was very average, and the four thousand Wei troops blocked the attack of the 10,000 Shu thieves, and they fought quite decently at the beginning.

But as time went by, the battle entered a white-hot heat, and there were too many intertwined with each other, and the left-wing Shu thieves showed a very strong advantage in chaotic warfare.

Once the two sides entered the stage of entanglement, the effectiveness of the military formation was weakened, and the Wei army on the left flank fell into a bitter battle in an all-round way.

In addition, they are at an obvious disadvantage in numbers, and there is no lunge to help suppress the rear wing troops of the Shu thieves, so they must rely on the will to fight of the soldiers. If it weren't for Cao Zhen's efforts in the morning and stimulated his own will to fight, if it had been yesterday, I am afraid that the left wing would have collapsed long ago.

But even so, if the left does not send enough reinforcements, it may not be able to hold out for long.

It's not that there are no reinforcements, and you can send Wang Chang's siege army to support, but in this way, Wang Chang's siege efficiency will be affected.

Today, Tongguan is the key to the escape of the Wei army, and there is no room for error.

Therefore, Cao Zhen thought about it for a while and decided to transfer a thousand men from his side to rush to the left flank to support the defensive line.

And the middle lane is here. Anyway, Zhang Xi's middle route army does not cooperate with each other, and he can resist for a while, probably it doesn't matter.

In this way, the frontal battlefield of the Wei army was a situation of personnel transfer.

And Zhang Xi here. Zhang Xi was indeed limited by the adverse influence of the coordination between the Liangzhou infantry and the Yongzhou infantry, resulting in low offensive efficiency.

There's no way, Zhang Xi really can't figure out what these Liangzhou soldiers are thinking.

In view of the fact that these Liangzhou soldiers had just arrived at the battlefield after a long journey, so the combat task was heavy this time, and the right flank was handed over to Su Ze for command, and Su Ze was only required to play a role in containment.

This is a combat arrangement made out of consideration of the actual situation, and it is also a practice to take care of the Liangzhou soldiers.

But as soon as the battle began, the right wing of his own side was the first to launch an active attack, and on his middle side, the Liangzhou soldiers, who were supposed to undertake the flank cover operation, suddenly seized the way forward, squeezed the offensive line of the Yongzhou soldiers, and began to attack on their own.

This forced Zhang Xi to make the first tactical adjustment today, letting the Yongzhou soldiers give way to the flank attack, and it was already a little unhappy to give up the main attack position to the Liangzhou soldiers Zhang Xi.

What are these Liangzhou soldiers doing?!

Well, if these Liangzhou soldiers can cooperate with each other and attack Cao Zhen's army in the middle together, Zhang Xi will not be too hairy. But on several occasions, the Liangzhou army did not wait for the Yongzhou army to attack at all, so they launched an attack on their own, giving the Wei army a chance to focus on defense, and the Yongzhou army finally attracted Cao Zhen's army through the flank attack, and the Liangzhou soldiers temporarily retreated and adjusted the attack.

The offensive rhythm of the two sides has not been on the same point once.

Zhang Xi was a little angry, it was the first time he had encountered such an army since he joined the army.

You say they don't obey military orders, but you can't say it.

Although a flank attack on Liangzhou was arranged, it was essentially necessary to attack the Wei army, but the attack deviated from the main direction of attack, resulting in the frontal attacking troops having to move to the flank.

But you have to say that they obey military orders. In the current situation, Zhang Xi doesn't think that this is an act of obeying military orders.

Seeing that the attack was not going well, and Cao Zhen still had the spare strength to divide his troops to help the flank, Zhang Xi didn't care, and just let it go.

He ordered the Yongzhou army to temporarily retreat and use it as a reserve, so that the Liangzhou army could directly attack the main attack.

According to Zhang Xi's idea, since the cooperation between the county soldiers on both sides is not good, it is better to fight separately, when the Liangzhou soldiers are attacking, the Yongzhou soldiers retreat as a reserve, and when the Liangzhou soldiers complete an attack and retreat to rest, the Yongzhou soldiers will go up again and launch an attack in the way of wheel warfare.

This not only ensures the pressure of the attack, but also does not have to worry about the coordination between the two armies.

Of course, in this way, it is indeed possible to reduce the offensive forces, but instead of fighting on both sides, sometimes they have to hinder each other, but it is better to use this way Anyway, Cao Zhen only has more than 3,000 people in his hands to defend anyway.

Zhang Xilai is such a hand, but Cao Zhen is under a lot of pressure.

At the beginning, because the rhythm of the Shu thief's attack was sparse, the pressure on Cao Zhen was not great, and Cao Zhen dared to divide a thousand troops to support the left flank, but now it is okay, Zhang Xi has adjusted it like this, it seems that the number of enemies that the Wei army needs to face directly is less, but the combat effectiveness has been qualitatively improved.

The two sides have been entangled to a certain extent, although the Liangzhou soldiers are not good at military battles, but the soldiers are brave, good at chaotic battles, and if they are hand-to-hand combat, they are really no worse than the individual soldiers of the forbidden army under Cao Zhen.

But fortunately, there are few Liangzhou soldiers in the middle road, only about 4,000 people, and after a period of fighting, there are also some battle losses, and the total strength is about the same as the remaining troops in Cao Zhen's middle road, and Cao Zhen can continue to support.

But if the Liangzhou soldiers retreated and the Yongzhou soldiers continued to attack, the Yongzhou soldiers had the advantage in strength, and they were good at military formations, and the pressure on the Wei army in the middle was greater than that of the Liangzhou soldiers.

What's worse is that these two troops have different combat styles, but they use the method of wheel warfare, constantly consuming the strength of the Wei army. Cao Zhen wasn't sure if he would be able to make it until dark.

The only thing that can be counted on now is that Wang Chang can break through Tongguan as soon as possible and open up his own back road, otherwise, even if Cao Zhen's side can hold out until dark, it is uncertain whether he can continue such a two-sided battle early tomorrow morning.

The casualties of the rear defense were too great.

And Wang Chang is here. Wang Chang was also trying his best to attack.

Ketongguan. Wang Chang is also regretting that when he was the general of Tongguan, he had nothing to do with raising the Tongguan city wall.

Tongguan was originally built by Emperor Taizuwu in order to defend the Liangzhou legion in Guanzhong, and when it was originally built, the purpose was to build a Xiongguan, so the height of the wall of Tongguan was originally very high.

Later, when Wang Chang served as the guard of Tongguan, because Zhang Xi took a group of counterweight catapults to smash out of the psychological shadow, so while constantly thickening the city wall, Wang Chang also played the imperial court and asked the court to allocate funds to raise the Tongguan wall by another zhang, so as to block the damage of the trebuchet's upward shot to the guards on the city wall.

Well, the trebuchet is on guard for the time being, but now it's the turn of their own soldiers to climb the eight-foot high wall to attack.

Siege of this kind of thing, the higher the city wall, the greater the difficulty of siege, this is the general military common sense, the eight-zhang high wall, itself is an insurmountable barrier.

In addition, now that the Shu thieves have pursued to the rear, it is impossible for Wang Chang to go out of the camp to cut down trees thirty miles away to build siege equipment, so he can only use the ones prepared before, which is to destroy one less plane, and there is no supplement.

Therefore, attacking Tongguan has to rely more on human lives to pile up, and the attacker really has no good way.

Wang Chang also fought very hard, and out of urgent need to siege the city, Wang Chang also organized soldiers to attack the city in wheel warfare, and did not give the Shu thieves defenders at the head of the city any time to rest.

Now for Wang Chang, the only good news is that he has a large number of people, and after some encouragement in the morning, the soldier's will to fight is also much stronger.

In today's siege, someone in the Wei army was finally able to climb the wall and fight hand-to-hand with the Shu thief defenders.

Although it was quickly driven down by the Shu thief defenders, it also smashed a hook ladder. But that's a good sign.

Wang Chang knew very well that there could not be too many Shu thief defenders, and after so many days of siege, there must be a lot of casualties, and there would not be too many troops on the city wall to hold on.

As long as you can continue to put pressure on the wall and break through more, you will definitely have a chance to occupy the landing point on the wall and transport a large number of Wei troops to the wall for hand-to-hand combat.

And once the Wei army occupies the city wall, it won't be long before the Shu thieves can retake Tongguan and the Shu thieves are in Tongguan, and there are not enough troops to hold on.

Therefore, Wang Chang ordered the whole army to attack!!
