In September 201 B.C., Maudun led 400,000 troops south to besiege the Korean capital of Mayeup.

Han Wangxin saw the majestic Hun cavalry at the head of Mayi City, and couldn't help but secretly sweat. With his many years of battlefield experience, he could conclude that with this little soldier and horse in his hand, he could not resist the Hun iron cavalry at all.

He fortified the walls and cleared the wilderness, held on to the city, and at the same time sent envoys to the imperial court for help.

Liu Bang received an urgent report from the border pass, thinking that the Xiongnu were just barbarian tribes outside the fortress, and did not pay too much attention to it, and Chang'an and Mayi were thousands of miles apart, and the weather was getting colder, and the army sent was not an elite division, so the march was not fast.

Han Wangxin could not hold out, and if the Xiongnu could not attack for a long time, he would definitely retreat. But Mao Dun understood Han Wangxin's psychology, and he didn't wait long for him to order the siege of the city, and the Xiongnu army was like a rainbow, no matter how strong the city of Mayi was, it would not be able to support it for long.

Han Wangxin saw that the imperial army was delayed, and the Xiongnu offensive was becoming more and more fierce, and if this continued, the city would be destroyed and slaughtered sooner or later, so he decided not to report to Liu Bang and sued the Xiongnu for peace without authorization.

When the imperial army was halfway through, he had already learned the news of the peace talks between Han Wangxin and the Xiongnu, and the Han general thought that this matter was very important, and urgently ordered the whole army to stop advancing, and at the same time sent an envoy to report to the imperial court.

Liu Bang couldn't help but be furious when he learned that Han Wangxin had negotiated peace with Mao Dun without authorization, he had recently been suspicious, and he often chased after the wind and shadows, thinking that the princes and kings were not honest, and the news of the peace talks deepened his suspicion of Han Wangxin. Liu Bang immediately sent an envoy to Mayi to reprimand Han Wangxin: Why don't you wait for the order and ask for peace without permission? I want to remind you that in this time of life and death, if you want to die, you will be brave, and if you survive, you will be wasted, how can you fight and seek peace at the same time?

Han Wangxin was scolded, knowing that Liu Bang had become suspicious, before Liu Bang moved his fiefdom north was a sign of distrust, and now in extraordinary times, there is no argument, if this continues, in addition to dying in battle, there will be no good fruit to eat when he is alive.

King Han is confident that he will simply not do anything, it is better to surrender to the Huns, who is the master and not the master? Moreover, the Xiongnu iron cavalry was so brave, and the Han army was not necessarily an opponent, and maybe the Central Plains would soon become the world of the Huns.

After holding on for a month, Han Wangxin opened the city gate and dedicated Ma Yi to Mao Dun, officially surrendered to the Xiongnu, Mao Dun accepted Han Wangxin's surrender, and reused Han Wang Xin with great courage, ordering him to be the front army, and the Xiongnu army then attacked and advanced in the direction of Taiyuan.

The Xiongnu army, with the help of Han Wangxin's army, plundered along the road.

Liu Bang was furious when he received the news that Han Wangxin had surrendered to the Xiongnu, and he was even more furious when he learned that the Xiongnu had burned, killed and looted in the country.

In October 201 BC (the seventh year of Gaozu of the Han Dynasty), Liu Bang led 320,000 horses to march in person, preparing to fight against the arrogance of the Xiongnu.

The Han Dynasty almost went away empty this time, and almost none of the ministers and generals were left behind, except for Han Xin and Zhang Liang, of course. Liu Bang hoped that this personal expedition could defeat the Xiongnu in one fell swoop, solve the border defense problem once and for all, and take this opportunity to solve Han Wangxin by the way, and firmly grasp the power of the Yan Dynasty in the hands of the Liu family.

The Han army attacked separately in three forward armies to clear obstacles for the main force and wait for a decisive battle with the main force of the Xiongnu.

The first advance of the Han army, under the leadership of Zhou Bo, encountered Han Wangxin's troops in Tongba (present-day Qin County, Shanxi), and fought a battle, Han Wangxin retreated again and again, and finally retreated back to Mayi. The second vanguard of the Han army is the light cavalry led by Guan Ying, and the Guan Ying Department has already rushed thousands of miles to arrive in Ma Yi first, and cleared the rebel army around Ma Yi and part of the Xiongnu army, and so on Han Wangxin was defeated and fled back, Guan Ying attacked with light cavalry to disperse Han Wangxin's troops, and Han General Wang Xi made a ghost under the knife. The third route of the Han army, led by Fan Xu, went to Izumozhong County in Huoren County, intending to cut off the return route of the Xiongnu.

Han Wangxin was defeated again and again, his heart was flustered, and he hurriedly asked his subordinates for a plan, and the general Man Qiucheng and Wang Huang gave him a bad idea, and they suggested that they should find the descendants of the Zhao royal family, make him the lord of the country, and use it as a shield.

The army pressed the border, and they had to find a stronger one to find a shield, but instead they found a descendant of the Zhao family who was powerless, as if they could be safe with this shield. How can you be so naïve and undefeated?

Han Wangxin sent people to ask for help from Maudun, who was stationed in Shanggu. Mao Dun learned of the Han army's three-way forward army's successive victories, realized that the Han army was not easy to deal with, although many generals had the idea of retreating, but Mao Dun did not waver, he found out that the main force of the Han army was heading towards Jinyang, after thinking repeatedly, and checked the nearby terrain several times, when he saw Bai Shan not far away, he immediately laughed.

That's it! That's it! Liu Bang, if you dare to come, this is your burial place! Maudun thought to himself.

In order to lure Liu Bang into the ambush circle, Mao Dun sent the left and right Xianwang to lead the weak army to attack Liu Bang's main army all the way, according to Mao Dun's order, only defeat is not allowed to win.

Mao Dun was roasting the fire in the tent, drinking hot mare's milk wine, constantly sending people to investigate the movements of the Han army, and now everything was ready, just waiting for the Han army to step into the trap.

Liu Bang led a large army and stationed it in Jinyang.

At this time, it was the cold winter of October, the snow was falling, it was very cold, the Han soldiers were frozen to the flesh, their hands and feet were stiff, and coupled with the fatigue from afar, the morale was very low.

For the sake of safety, Liu Bang did not immediately look for the main force of the Xiongnu for a decisive battle, but sent a large number of envoys to explore the movements of the Xiongnu. This was the first frontal war between the Han Dynasty and the Xiongnu, which had a direct relationship with the national fortunes.

Liu Bang knew that if he could solve this jackal-like nomad, he could provide an environment for the newborn country to recuperate, and if it could not be solved, it would haunt the present and future of the Han like a ghost.

Liu Bang suddenly understood Qin Shi Huang a little. In the past, when he was in the people, he often scolded Qin Shi Huang for tyrant, scolded him for working the people and money, and requisitioned millions of people to build the Great Wall, but now he understands a little that Qin Shi Huang took the blame on his own head and left peace to future generations. Qin Shi Huang's difficulties can only be understood by standing at his height!

This may be the sorrow of being an emperor!

The messenger sent out came back and reported: The Xiongnu army is old and weak, and the follow-up is insufficient, it can be fought, and if it is fought, it will be won!

When the first person said this, Liu Bang was still a little unconvinced, and thought: If the Xiongnu are really so weak, Han Wangxin is also a veteran of battle, how can he be afraid of them? It seems that Han Wangxin has long had the intention of rebellion.

The envoy who came back later came back to describe the situation of the Xiongnu, which was roughly the same as the previous one. Liu Bang was suspicious, but still ordered the whole army to advance. When he arrived in Guangwu, he was a little unsure, so he decided to send Liu Jing (remember him, Lou Jing), who had not been in office for a long time, to check it out again.

Liu Jing went on a trip and came back to report to Liu Bang, what he saw and heard was the same as the reports of all the envoys, but he came to a different conclusion: the Xiongnu were a trick to lure the enemy, and they couldn't be fought!

Liu Bang was puzzled.

Liu Jing said: The war between the two countries will definitely show their strength, and now there are old and weak Hun soldiers all the way, isn't this very abnormal? The ministers expected that this was a plan by the Huns to lure the enemy!

It should be said that Liu Jing is very level, he can see the essence through the phenomenon, although he won the official with one word, he does have the level of being an official, and the level cannot be covered.

Of course, Liu Bang understood that Liu Jing's words made sense, but he still scolded Liu Jing and imprisoned him in Guangwu, threatening to come back and clean him up.

In Liu Bang's style, he would not imprison a courtier because his advice was inappropriate, but this time he was unusually angry, which is a strange thing! In fact, the reason is very simple! The morale of the Han army was too low along the way, and if there were any more unfavorable remarks against their side, it would inevitably affect their morale even more. Moreover, he didn't know much about the Xiongnu, because he didn't understand it, so he looked down on it, he thought that even if he fell for the Xiongnu's trick to lure the enemy, the Han army could easily break through.

Once again, Liu Bang paid the price for his underestimating enemy.

The Han army marched all the way in the direction of Shanggu, and Liu Bang's light cavalry troops were the first to reach Pingcheng.

Suddenly, the ambush came out, the arrows rained down, Xiahou Ying led the troops to resist the first wave of the Huns' attack with shields, after the arrow rain stopped, the Huns launched a second wave of offensive, this time it was not so easy to deal with, the Huns dispatched his strongest troops - the iron cavalry. All of a sudden, thousands of horses galloped, the earthquake trembled, Mao Dun led the elite iron cavalry of the Huns to rush over, and the Han army was inevitably in chaos.

The Han army is also a seasoned division that has been in battle for a long time, although it has no power to fight back, but it also has the ability to parry.

However, the Hun cavalry was too brave and they waited for work, and the Han army was tired from afar, and after a while, the Han army suffered heavy losses. Seeing that he was about to be defeated, Chen Ping suggested that Liu Bang order the troops to retreat to Baishan Mountain, and at the same time ordered Xiahou Ying to lead a part of the troops to build a wooden fence array on the spot to stop the onslaught of the Xiongnu cavalry. On Baishan Mountain, the cavalry superiority of the Xiongnu will not be able to be developed, and the Han army can temporarily put the predicament on the way.

The wooden fence built by the Han army had an effect, the Hun cavalry was blocked from the formation, and the main force of the Han army retreated to gain time. Seeing that the cavalry was blocked, Mao Dun ordered the archers to launch a stray arrow attack, and Xiahou Ying could only lead his troops to fight and retreat, and after a bloody battle, he retreated into Baishan Mountain. The Xiongnu soldiers followed into the mountain, the main force of the Han army had already occupied the favorable terrain, and the pursuers of the Xiongnu were knocked down the mountain several times, but the Han army did not dare to attack the mountain, so they could only hold the danger. So, Mao Dun changed his strategy, stopped the attack, and divided his troops to surround Bai Mountain.

The Han army retreated into the mountain, was about to take a breath, suddenly there was a killing sound in the valley, the Hun ambush soldiers from the valley to kill, it turned out that Mao Dun had already expected that if the Han army retreated into Baishan Mountain, it would break through from the valley, so he planted an ambush in the valley in advance, and trapped the Han army on Baishan Mountain and could not move.

The Han army was in a dilemma.

At this time, Liu Bang realized Liu Jing's golden and jade words, if there was really a regret medicine in the world, Liu Bang would not hesitate to drink a pot of it, but unfortunately it was too late to regret it now, he was like a prey in a trap, just waiting for Mao Dun to slaughter.

Although the situation is critical, Liu Bang is not completely desperate, he has failed countless times on the battlefield, he can get up countless times, and the more he lives, the better he is, the battle of Pengcheng was not better than this time, he has suffered it all! He believed that this time he would be able to survive the same!

But the problem now is that he is not facing Xiang Yu, who has a intestine leading to the end, but a cunning Maodun. Mao Dun can be called a perfect enemy, he is thoughtful, brave, he has absolute loyalty, he is a steppe iron horseman, he is cruel and ruthless, even his father and wife dare to kill, can you expect him to be merciful and let Liu Bang go?

No way!

After the Xiongnu iron cavalry forced the Han army into the mountains, Mao Dun ordered a siege but not an attack, cut off the water source of the Han army, and at the same time sent troops to intercept the way of reinforcements, and then set up a big tent, make a fire to cook, and make a permanent appearance, intending to trap Liu Bang to death on Baishan Mountain.

Liu Bang has realized the seriousness of the problem, he summoned his subordinates to discuss the strategy of breaking through, everyone scratched their ears and scratched the silk, in addition to the strong breakthrough, they couldn't think of any good way, even the always clever Chen Ping was helpless for a while, at this time, Liu Bang began to miss Zhang Liang.

If the ovary was here, maybe he could have a good solution. Liu Bang sighed in his heart.

If you don't find a way to break out of the encirclement as soon as possible, the Han army will soon run out of food and water, and when the Huns attack again, the Han army will be annihilated. The ministers said.

In desperation, Liu Bang ordered the generals to organize a breakthrough, but each time they were driven back by the Huns.

At this moment, Liu Bang really realized that the barbarian leader he had always looked down on was not a simple enemy!

In the harsh winter of October, the weather was very cold, and the Han army was trapped on Baishan Mountain.

There is less and less food, and less and less water!

If there is no way, I am afraid that without the Huns going up the mountain, the Han army will also be starved to death and die of thirst.

In this situation, in addition to praying for God to bless the Han, all Liu Bang did was wait, waiting for the arrival of reinforcements and waiting for a miracle to appear. He suddenly found that he seemed to be in a desperate situation, and the current state of affairs was even worse than the situation of Pengcheng's defeat back then. At that time, he had a very deep understanding of his opponent, but now, he had no idea what kind of opponent he was facing and what cards this opponent would play.

Fear because of ignorance!

Everyone is trying to find a breakthrough, and everyone's hearts are becoming restless in this small mountainous area.

One day

Two days,

Three days...

The shouts, excitement, and ridicule of the Hun soldiers under the mountain have become the nightmare of every Han soldier, I really don't know where these fierce Hu people came from, they are all brave and good at fighting, all of them are abnormal, they are like devils born for war, which is terrifying.

These days, Chen Ping has also been sleepless all night, and he deeply feels his responsibility. Zhang Liang is gone, he, the lieutenant of the guard, is the first adviser of the Han Dynasty, if he can't come up with an idea at this critical juncture, then who else can the emperor rely on? And he himself will become a sinner through the ages.

Chen Ping firmly believes that there is no endless way to heaven, and there is no perfect enemy.

Chen Ping secretly sent a lot of spies in disguise to investigate all the details of the Xiongnu troops, and to investigate the details of Mao Dun and his surroundings.

Hard work pays off.

Chen Ping finally found a way to break through the steelman-like Maoton, and that was his Yan clan. Mao Dun's newly established Yan clan is deeply favored by Mao Dun, so he must take her with him every time he goes out!

At the moment when Chen Ping came up with a solution, the Han army had been suffering for seven days and seven nights in Baishan Mountain.

Woman's jealousy.

It turns out that often what men can't do, women can do. Things that are often not done at the front desk can be done in the backyard.

Women have been able to hold up half the sky for a long time.

At this time, Liu Bang had become an ant on a hot pot. Chen Ping told Liu Bang about his strategy.

The saddest thing in the world is that people die, and money is gone. Gold, silver, and jewelry, not brought in life, and not in death. Liu Bang decided that no matter whether he was dead or alive tomorrow, he would take out all the gold, silver and jewelry in the army, and even took off the night pearl on his hat for Chen Ping to go to the event.

At the foot of the White Mountain, there is a single big tent.

The fog is blank.

An envoy with a Han Dynasty envoy talisman walked outside the barracks and said to the doorman: Please let me know, I am a Han envoy and want to see Mrs. Yan.

As he spoke, he secretly handed the doorman a gold ingot. The doorman accepted the gift money, and naturally he was happy to report it.

When the Yan clan heard that the Han envoy had come to look for her, she planned not to see her. She saw that Shan Yu was still drunk and had not woken up, and she was afraid of delaying the big event, so she retreated left and right and summoned the Han envoy in the inner tent.

The Han envoy presented all kinds of gold, silver and jewelry, and Yan's eyes suddenly lit up. The Han envoy saw that the Yan family was happy, and presented a picture of a beautiful woman, and the Yan family was puzzled. The Han envoy said to the Yan family: "This is the beauty that my lord wants to give to Shan Yu, but considering that the Yan family has no grudge against my lord, the shilling envoy came to inform the Yan family Niangniang, if Shan Yu continues to besiege, my lord will definitely send this beauty and Shan Yu, and at that time, the status of the valve clan will not be able to be maintained......"

Yan Shi was suddenly shocked, thinking that he had just been favored by Shan Yu not long ago, if he was favored by others, the future would not be easy, so he said in a low voice: Ambassador, then what should I do?

Yan Niangniang, just tell Shan Yu as I said, Shan Yu will definitely retire, and then Niangniang can keep your position.

In order to avoid the loss of his position, the Yan family agreed to admonish the Han army.

After Mao Dun woke up, Yan Shi said to Mao Dun: Shan Yu, do you still have the heart to sleep? Someone came to report just now that the Han Dynasty had sent a large army and was rushing to the rescue.

Shan Yu said with a smile: What is there to fear from the Han army?

Shan Yu is really confident, the Han Emperor was trapped here for seven days and seven nights, the Han Dynasty will definitely do its best to save it, and our army is far away from the homeland, the foothold is not stable, and the grain and grass materials are used less every day, how can it be sustainable?

After hearing this, Mao Dun thought about it carefully, and this was not false.

And seven days have passed, Han Wangxin's troops have not arrived as promised, if that guy and the Han Dynasty team up to trap themselves, then the situation is not good, and the pressure can be imagined at that time, even 400,000 iron cavalry is not easy to win. In addition, Mao Dun sent people to check the situation of the Han Dynasty everywhere, and found that this country was not as rich as imagined, and there were ruins and broken walls everywhere, and the scorched earth was everywhere. Where did the beautiful women come from?

Nomads have always been unapathetic to sedentary life, and it is better to kill them if they live in a place where there is no grassland, cattle and sheep. You know, Mao Dun is here to rob, not to kill, although often robbery is usually accompanied by murder, but if you can not kill, you will not kill, waste your energy and carry a bad reputation, it is too cost-effective. This is the rule of the robbery industry, and to put it mildly, it is also called morality.

The rivers and lakes have the morality of the rivers and lakes, and the country has the morality of the country.

No matter what morality it is, a shrewd Mao Dun will not make such a loss-making business.

After thinking about it, coupled with the fanning of the concubine, Mao Dun agreed to let the Han army live after planning his own retreat. The next day, Mao Dun ordered to withdraw a corner and let the Han army go down the mountain.

When the Han soldiers saw the Xiongnu withdrawing from the siege, they all cheered.

Liu Bang was afraid that he would regret it, so he hurriedly ordered the whole army to retreat down the mountain quickly, and it must be done in an orderly manner to prevent a sneak attack by the Huns.

It was foggy and the vision was unclear. The Xiongnu saw that there were many soldiers in the Han army, and they were in good order, so they did not dare to go up and pick up some cheap.

Liu Bang, who was besieged for seven days and seven nights, finally picked up an old life, and added another stroke to his failure record.

The first round of the contest between the Han Dynasty and the Xiongnu ended in the complete defeat of the Han Dynasty.
