With the retreat of Le Qi, the periphery of the Han army was dredged in the east-west direction of Yongdao, and the flying horses galloped, passing military letters and orders back and forth.

In the wilderness, you can see rows of rejecting horses arranged by the Wei army at night, and there are also new soil dug out of horse pits, and the new soil that has not yet dried is different from the old soil.

When they got closer, the wooden thorns, iron thistles, and low tripwires were arranged vertically and horizontally, plus the iron thistles discarded at will when the Wei army retreated, and the wilderness was not conducive to flying horses.

Damage to horses is a small matter, and delaying the spread of military documents is the real big thing.

Therefore, the Han army flew around with twists and turns, walking in a safe passage.

Not only did Ma Chao send a military letter to make an appointment at the time and promise to participate in the war; Zhou Cang and Xiahoulan, who were defending the east-west horizontal inner side of the Yongdao behind the camp of Ma Chaozhong, also promised to participate in the war.

Autumn rain is coming, who in the whole army is not in a hurry?

In the northwest corner, the cavalry position of the Wenqin Department of the Wei Army, at this moment, the men and horses unsaddled and rested, divided into more than a dozen scattered groups of large and small, and rested in groups, so as to quickly assemble.

Wen Qin led more than ten horsemen to watch the array of the marching column of the Beifu soldiers, and recognized Yu Zhong at a glance, Yu Zhong was in a red robe and black armor, with a five-pole battle flag on his back, and he still looked like a peacock.

Yu Zhong was followed by more than ten riders, and when he saw Wen Qin's more than ten riders from afar, he didn't care.

Not only him, but the three battalions of the Huya Army marching on his flank waved their flags and didn't care about it.

The marching column of the Huya Army was divided into three small columns, each with ten people; The most marginal marching chiefs and captains supervised the marching process, and the sergeants were strictly forbidden to turn their heads left and right, so they could only hold their heads high and look ahead.

Only the officers and generals at the edge of the marching column could observe the surroundings, and the generals and battalion governors rode on horseback, and there were also middle-level military officers who liked to walk.

The Huya Army was the elite of the Han Army, and those who marched to the front row were the elite of the elite.

Not to mention Wen Qin's more than a dozen horsemen, even more than a thousand cavalry Wei troops appeared on the flanks, and the Huya army was not afraid.

Wen Qin looked over and observed, and said to the left and right: "This formation is not attackable." ”

He sighed with a little regret, but it was a pity that the Beifu soldiers did not attack at night, otherwise exchanging injuries for injuries would be enough to break Tian Xin's invincible arrogance!

Look at the Beifu soldiers, there is no one in their eyes, and they regard themselves as grass mustard.

I really want to gather the knights and go around the formation to scare the Beifu soldiers to see if they are afraid.

But when Dianman retreated, he arranged the thistle at will, but the thistle had no patriotism and would not open up to the knights under his command.

I just thought about it in my mind, and seeing that there was no new banner order on Zhang Liao's side, I instructed: "Withdraw to Yaoshan according to the plan and bluff." ”

"Yes!"

The officers on his side replied one after another, turned their horses' heads and returned to their positions, blew the trumpet, left a large piece of fishy horse dung, and retreated to the mountains and forests.

The banners of the Wei army that have been arranged in the mountains and forests, are they suspicious soldiers, or are there really ambush soldiers?

Wankou defense line, the withdrawn Dianman, Zhang Hu, and Le Qi are stepping up their meals and resting.

Zhang Liao observed on the Great Wall and saw that many officials hung their heads or were stunned, there was not much noise, and the atmosphere in the army was dull.

A military official strode over with a bamboo slip and reported in a low voice: "The lower official has made it clear that the person who guarded the camp last night was Ma Chao himself." His younger brother Ma Dai built a camp to look at the north of Huating, and last night he attacked Dongshan to attack my first battalion in the east, because he saw that Ma Chao was in danger, so he returned to the division to rescue. ”

"The officers and soldiers of our army mistakenly thought that the Marquis of Changping sent troops to help in the battle, but the Yuzhou soldiers were not prepared and were annihilated by Ma Dai."

Zhang Liao couldn't help but feel some tightness in his chest when he heard this, which could be described as unfavorable in the first battle.

The night attack tactics that have been arranged and trained for a long time are not fished out of Tian Xin, and Ma Chao is just let go.

One after another, the development process of the war situation summarized by the prisoners and the soldiers participating in the war was compiled into a book, which made Zhang Liao a little incomprehensible.

If Tian Xin was advised by Pang Lin, it would be understandable that he did not send troops to rescue at night.

Then Guan Yu's front army in the rear, why didn't he rescue Ma Chao?

Distance is never a problem, let alone only thirty miles, not too far.

There is no need to rush to Ma Chao's camp to participate in the war, as long as you send troops, you can instigate the battle situation and support Ma Chao.

But Guan Yu didn't move?

There are only a few ways to break through the defense line of Wankou, and Guan Yu's main force did not rescue and support Ma Chao who was in danger.

Is there not enough troops, only the strength of the garrison?

Did the main force take the ancient crow road and seize Chu Yu Pass?

The terrain of Chuyu Pass is not precipitous, and there is enough width for the attacking troops to spread out and arrange...... Even if the troops were divided to surround the pass, the main force crossed the pass and directly sent troops to Yaoshan, appearing in the north of Yexian County, and it could also open up the Luyang Pass and appear in the southeast of Luyang County.

The pass is like this, and there are not many such Xiongguan as Yanmen Pass. The vast majority of gates are more like strongholds, set up at dangerous, critical, and must-pass intersections.

And the intersection is very wide, and there are even many small roads, and it is impossible to block the intersection like the Great Wall. You have the manpower to repair and the material resources to maintain, but how many troops do you have to garrison?

Therefore, many passes are selected at the intersection of dangerous mountains to build passes, camps, the terrain outside the passes is wide, that after the passes are surrounded, the defenders in the passes can only be trapped, powerless to interfere with the normal march of the other side.

However, the terrain of the construction of the fortress is steep, and there is generally a water source, so it is almost difficult to capture it before the grain is exhausted.

The casualty ratio of attacking the fortress is somewhat terrifying, and if it is stormed, the gains often outweigh the losses.

For example, if you look at the little-known names of Shuyang Pass, Chuyu Pass, Yunyang Pass, and Luyang Pass, you will know that these passes are not famous for being steep and important.

Under the specific battle situation now, these three levels have become side battlefields, so that the Han army and the Wei army have to divide their troops to garrison.

Among them, the Huaiyang Pass is in the upper reaches of the Shuishui, which is the stronghold of the Han army.

Not long after, Liu Gan, who was lucky not to die, was brought to Zhang Liao, and Liu Gan took the initiative to destroy the dam and drowned more than 300 Wei soldiers.

After the downstream was salvaged and identified, there is now half a breath left.

Seeing that Liu Gan had been tortured and left a dark red blood line on the road he dragged over, Zhang Liao was not surprised and was accustomed to it.

It is appropriate to respect the warriors, but this hostile warrior does not honestly harm himself, and also brings hundreds of elites of his own side to the funeral...... Everyone will have grievances.

Zhang Liao looked at Liu Gan's face: "What do you have to say today?" ”

"Only death."

Zhang Liao turned his head to look at the military officials who came with Liu Gan, and the military officials were shocked and angry, and looked at Liu Gan angrily: "Liu Wenyi, why change your mouth!" ”

"Boom!"

Liu Gan spit a mouthful of blood on the other party's face, and turned his head to look at Zhang Liao: "Zhang Junhou, why don't you abandon the secret and join the light, and participate in the grand event with General Song Gong, and Sanxing Yanhan!" ”

"If you don't say this, I can still tolerate you."

Zhang Liao said and looked sideways to see the Beifu soldier array that was gradually pressing, and the forward was only three miles: "Go and bring the captured military officials and tie them in front of the women's wall, I will see if Tian Xiaoxian dares to attack me." ”

The military officer who was wiping the blood on his face stiffened when he heard this: "Marquis of Jinyang...... Abuse and surrender of the army, I am afraid that there is something inappropriate. ”

There are also military officials to advise: "This move is detrimental to the prestige of the imperial court, and I also ask the Marquis of Jinyang to think twice." ”

"There is no need to think about it, if this battle is lost and the country is weak, how can there be prestige?"

Zhang Liao's tone was resolute, and he glanced at Liu Gan, who was waiting for death with his eyes closed: "Only in this way can our soldiers isolate themselves from the enemy, and only then can they kill the enemy with all their might, and there is hope of breaking the enemy." ”

Before the specific location of Guan Yu's main force was clarified, the defenders of Yaoshan and Yexian could not move.

If the Wankou defense line did not produce the expected results, then Cao Hongwei's army, Xiahou Shangzhen's southern army, and Cao Xiu's southern army would only fight outside the hundred miles, and would not divide troops to help the battle.

With the superiority of troops, pull the Han army, and then concentrate forces to attack one part at the right time and cut off one of its fingers, this is the operational principle of the Wei army.

Your loyalty to Da Wei must be expressed by concrete actions!

The decisive battle has begun, and the Han army has captured the lives of dozens of officials, which is inconspicuous in the battlefield war.

But at this moment, it can play a lot of roles.
