The spies of the Department of Detective Affairs once recorded that the combat characteristics of the Yu army were "to form a column without fighting, to retreat and take advantage of it, to ambush the soldiers to cut off the food route, to brave the night to start a fire, to carry firewood in the wind, to feed themselves, to disperse and reunite, to be good at fighting, and to be able to cold."

That is to say, once the Yu army is arrayed, most of the time they choose not to fight the front and retreat directly. If they retreat, they will take the opportunity to pursue, like to set up ambushes, cut off food routes, are good at night fighting, bring their own or loot supplies, gather and disperse quickly, and can quickly gather after scattering, good at fighting, and hardy.

In the final analysis, this is why Yongguo has won many battles against the Yu army, but strategically it seems that it has never been able to fight, because it can't fight a war of annihilation!

Yongguo has many infantry and good equipment, and most of the Yu army's honest frontal battles can be won by the Yong army, but they are not fools.

Most of the battles won by the Yongjun army were routs, and once the Yu army won, it would become a war of annihilation, and people would not be able to outrun.

Li Desheng once said in his guidance to the army that we should not fight a rout battle, but should fight a war of annihilation as much as possible, and in the face of a powerful enemy, a rout battle would be meaningless.

This is another important reason why Wang Rong let Yique Pass be attacked by the Yu army, allowing them to concentrate their forces and consume morale is only one of them.

Another point is that if the two armies meet directly, and the Yu army sees them in formation, the first reaction is most likely to retreat, not to engage with their own side, and let their own side line up in vain, or follow behind the buttocks, consuming morale, food, and physical strength, and then they will wait for the opportunity to counterattack.

And now they have set up a large camp to fight Yique Pass, the Tang army is distributed in the east, south and north to oppress the Yu army, and the two cavalry of Xiao Cavalry and Hussar Guard in the rear of the large array have been prepared.

At this time, if the Yu army dared to retreat again, the Tang army in the northeast would attack the flank of the Yu army, and the Tang cavalry in the southwest would come out from the front of the large array, and the flank impact alone would be enough for them to drink a pot.

In this situation, the commander of the Yu army also understood that there was only one way for them to repel or defeat today, and a frontal battle was inevitable.

In the distance, the cavalry of the Yu army began to march out one after another, each team was about a few hundred people, and there were dozens of teams, and they shouted and circled to the west, not in a straight line, but to detour the left flank of the large formation.

In addition, there were a large number of cavalry with better equipment in a line, and a column of cavalry was far away from the front of the large array, slowly approaching, but always a distance of about a mile from the front of the large array, not close, as if waiting for something.

Wang Rong looked at the large number of slowly approaching cavalry teams in front of the left flank, and also understood what they were waiting for.

Soon, with the sound of horns in the distance, the sound of horses' hooves became more and more dense, and a group of Yuguo cavalry shouted and detoured to the large array, and gradually approached and began to open their bows and arrows, throwing pieces of black pressed arrows.

The Tang army's crossbowmen also counterattacked, but the local battlefield Yu army had a great advantage in numbers, the Tang army had a bow and crossbow advantage, the Yu army had a numerical advantage, the left flank instantly covered the sky with yellow sand, shouting to kill the sky, the two sides fought between thirty and fifty paces, the arrows came and went like rain, and the clanging impact sound was endless.

A large amount of sand and dust was rolled up and circled with the cavalry of hundreds of people running in a group, and went straight to the sky, although they were in the same large array, but the left flank was a little far away from the Chinese army where Wang Rong was, and after the battle began, the dust was all over the sky, except for relying on the banner to see their position clearly, the specific situation was completely unclear.

However, when he discussed with everyone, he expected that the Yu army would attack the left and right, not only let Chu Luxu and Yuan Tiangang sit in command of the two formations at the front of the left flank, but also put the elite soldiers and well-equipped armor on the left flank.

The reason is very simple, the Yu army is good at riding and shooting, and riding and shooting on horseback, most people can only put arrows on their left hand, and the right side is a shooting dead angle, which is similar to the most elite soldiers in the infantry formation most of the right wing, because most of them are right-handed, and the elite soldiers can only exert their combat effectiveness on the right wing.

Therefore, as long as the Yu army is dispatched with a large number of light cavalry, the direction of the attack must be their left flank.

And in a place about a mile in front of the big array, the long cavalry line of the Yu army was also spreading out, slowly approaching.

Obviously, they are waiting for a large number of rangers on the left flank to consume the arrows and physical strength of the Tang army, and it is best to disrupt the Tang army's formation, so that the Tang army is exhausted, and the arrows are almost consumed.

spears and the like launched an assault.

Wang Rong looked at the past, and after the left flank engaged in the battle, he shouted to kill the heavens, and from time to time he could hear a scream, and a large number of arrows loomed in the sand and dust, buzzing, and even the sound of horses' hooves that shook the sky could not be concealed. Even after hundreds of paces, people have become small dots, looming in the dust, and he can still feel the fierce battle on the left flank.

Wang Xu took a deep breath nervously, grabbed the shield in his hand, there was a high platform in the Chinese army, just behind Wang Rong, standing the flag of the Chinese army, and on it stood the herald.

With the expansion of the scale of the war and the change of troops, the drumming march is no longer applicable in large-scale battles, and can only be used for the command of grass-roots troops.

Just like now the whole battlefield is the sound of horses' hooves, horns, shouts of killing, and the sound of metal clashing.

Drums and trumpets are still used to command between the various circular formations, but when it comes to the command system of Wang Rong's level, it is impossible to give orders by sound, the sound is too chaotic, the distance is too far, and the left and right flanks of the large array have exceeded one mile and approached two miles, not to mention beating drums and firing cannons, they may not be able to hear clearly.

The quadripartite flags have also appeared for a long time, and various flags have become a better choice for the commander to command the army.

Wang Rong sat in the middle of the army, watching the situation on the left flank from a distance, a large number of cavalry of the Yu army engaged the Tang army on the left flank, but did not dare to detour to the rear, because behind the flank of the large formation, more than 15,000 cavalry of the hussar guards were on standby, and they were afraid that they would be attacked from both sides.

Wang Rong also couldn't see Chu Luxu's place, the distance was too far, there was a road between the fields in the middle, and there were rows of trees on both sides of the road, but he could see the conspicuous banner in the distance, and he knew where the cavalry was.

Time passed minute by minute, the engagement on the left flank was not the previous tentative attack, and the Yu army sent at least a team of 10,000 people, arrived in close quarters in batches, and then retreated.

There were dozens of cavalry in a group of hundreds of people, and they also formed a huge circle in front of the left flank of the Don Army, alternating one by one, firing in batches.

The two circles in front of the left of the Tang army were under tremendous pressure, Zhang Yunshu looked very nervous, and several times he wanted to bring people to support, but they were all vetoed by Wang Rong.

In fact, he was even more nervous!

If the two round formations in front of the left are defeated, then the next battle will be difficult to fight, he asked Yuan Tiangang to personally sit in the far left front round formation, and also told him before the battle that if the people of Yu want to fight, they must be staring at them to fight, which is determined by the tactical characteristics of the Yu army, let him be psychologically prepared.

Yuan Tiangang swore an oath and promised him that unless everyone died, he would never collapse, but Wang Rong's heart was still anxious, and he had been hesitant to order the cavalry led by Chu Luxu on the other side of the avenue to support him.

But at this time, once the left flank reserve force was mobilized to support the front, it meant that the encirclement of the right flank of the Yu army was released, and the subsequent plan to destroy the enemy could not be completed.

Wang Bian was expressionless, didn't say a word, stared closely at the fierce battle in the distance in front of the left, the surface was unwavering, and his heart was already nervous to the extreme, at this time he could only choose to believe in Yuan Tiangang and many Teng Xiangwei's soldiers.
