The Qin army was obviously able to defeat the Xiongnu, but why was the Han army suppressed by the Xi

Because the Xiongnu were already strong during the Han Dynasty. At that time, the Han Dynasty was experiencing many years of war, and it can be said that they already needed to recuperate, so they could not fight the Xiongnu head-to-head.

The Han army was suppressed by the Xiongnu in the early stage, because the Han Dynasty had just been established and the national strength was not strong, so the Xiongnu were directly hung up and beaten in the middle and later stages.

The same Xiongnu, the reason why the Qin army could easily defeat him and the reason why the Han army could not do it was that on the one hand, the Qin army had fought with the Xiongnu for a long time and knew the habits of the Xiongnu very well, and on the other hand, because the Han army had experienced a long-term struggle between Chu and Han, its vitality had been lost, so a large number of troops could not resist the Xiongnu army. In addition, Liu Bang, the supreme commander of the Han army, was not particularly powerful against the Huns, so he could not defeat the Huns.

1. The army of the Qin Dynasty fought against the Xiongnu for a long time and understood the various habits of the Xiongnu.

When the Qin Dynasty was just established, because the whole country had been unified, their main battle was to deal with those Huns. Those Huns have been in a nomadic state for a long time, but the Qin army, which has always been in the northwest border, is no stranger to these Huns. Therefore, they knew very well what customs the Huns had, and where they would rest every year, and what their weakest point was, and it was with these Qin Dynasty troops that they could defeat the Huns several times, so that the Huns would be terrified when they heard about the Qin Dynasty's army.

Second, the army of the Han Dynasty after many wars was exhausted, and in addition, Liu Bang was not properly commanded.

Compared with the Qin Dynasty, which was able to easily defeat the Xiongnu troops, the reason why the Han Dynasty could not do this at all, on the one hand, was because the Han Dynasty had already experienced a long period of fighting, and the soldiers and troops under their command were completely unfamiliar with the Xiongnu army. In addition, they were very tired from the long battle. Most of the people did not want to fight, so they lost confidence and combat effectiveness in the army, and the Huns' assault tactics made them very afraid of the Huns.

Another point is that Liu Bang's command was very inconsiderate in these battles. He only thought about attacking, but he didn't discuss with his men what method was the most appropriate. As a result, he lost the best time and place to fight in this battle.

As a result, the army of the Han Dynasty was not able to defeat the Xiongnu as easily as the army of the Qin Dynasty, but was pinned down by the Xiongnu and finally defeated by the Xiongnu.

To sum up, the reason why the Qin army was able to easily defeat the Huns was because they knew the various habits of the Huns and they were very familiar with the Huns, while the Han Dynasty's army was exhausted due to long-term battles, coupled with the mistakes of the supreme commander Liu Bang, so they could not easily defeat the Huns' army.

Because the combat effectiveness of the Han army and the Qin army was very different, the combat capability of the Han army was weaker than that of the Qin army.

Because the attack power of the Xiongnu faced by the Qin army is not strong, it has not yet developed, it only knows how to defend, and the internal contradictions are fierce, so the combat effectiveness is not strong, while the Xiongnu faced by the Han army has developed, and the strength is relatively strong in all aspects, so it is more difficult to defeat it.

The times are different, the strategic goals are also different, the Han army is powerful and the four yi, and its troops are far superior to the Qin army, so this is the reason why the Han army is not able.

Because the Xiongnu they faced were not of the same grade, the Xiongnu that the Han army faced were the Xiongnu after the unification of Maodun, and their power was very strong.

The Xiongnu have always been an ethnic minority in the north, and they live on the steppe, and the people are fierce and have strong combat effectiveness. The Xiongnu were defeated by Li Mu, the general of Zhao during the Warring States Period, and after more than ten years of recovery, they invaded the Central Plains and were defeated by Qin Shi Huang with troops at that time. Later, Liu Bang, the ancestor of the Han Dynasty, fought with the Xiongnu, and was finally defeated and surrounded, and was bullied by the Xiongnu until Emperor Wu of the Han Dynasty completely defeated the Xiongnu and made the border peaceful.

So why did the Qin army easily defeat the Xiongnu, but the Han army couldn't? The Han Dynasty had just gone through the war in the last years of the Qin Dynasty, and the national strength was not strong enough to defeat the Xiongnu, the Qin Dynasty army had always been very strong in combat, and the Qin State was also better than the Han Dynasty at that time, so the Qin army was able to defeat the Xiongnu, while the Han army was not.

1. When the Han Dynasty and the Xiongnu were at war, the national strength was not strong enough, so they could not defeat the Xiongnu.

Second, the Qin Dynasty was strong, and the Qin army was brave and good at fighting, so it was naturally easy to defeat the Xiongnu.

3. The Qin army had excellent generals, while the Han army did not have outstanding generals at that time.

The Qin Dynasty itself was a nomadic people from the West, so it knew the advantages and disadvantages of the Xiongnu very well, and at the same time, the Xiongnu had not really become strong during the Qin period.

Because the comprehensive national strength and military ability of the Qin Dynasty were much stronger than those of the Han Dynasty, and it had many excellent generals.

First, the Qin army was strong.

That. Second, the growth of the Han army was too slow. The Han army was not a professional army.

That. Third, the Xiongnu grew fast. The Xiongnu in the Han Dynasty were already much stronger than the Xiongnu in the Qin Dynasty.

During the Qin Dynasty, the Xiongnu were scattered inside, so they were able to defeat easily. But by the Han Dynasty, the Xiongnu had been unified and their strength had greatly increased.

This statement is not correct, the Han army also easily defeated the Xiongnu in history. Wei Qing and Huo Qubing once led their generals to attack the Xiongnu's lair.

By the time of the Han Dynasty, the Xiongnu tribes had been merged into a large group, with strong strength and greatly increased military strength.

First of all, during the Warring States and Qin dynasties, the Xiongnu were not a unified regime, so they were not strong. Moreover, in the early days of the Han Dynasty, the domestic productive forces urgently needed to be restored, otherwise the national strength would not be enough to support the war against the Xiongnu.

In fact, for a civilization as we know it, the more backward it is, the lower the logistical needs of its army. The primitive nomadic and fishing and hunting civilizations had indefinite dwellings and did not need to be cultivated, and the places that needed to be guarded were not cities but pastures and water sources, and they were much more flexible than sedentary civilizations. In addition to children and the elderly, whose physical fitness does not meet the requirements, other teenagers and adults, both men and women, have a certain combat effectiveness.

Moreover, horses were essential livestock to live on the grassland, so the mobility of these steppe tribes far exceeded that of the Central Plains army, which was dominated by infantry and chariots at that time.

The armies in the Central Plains began to be more professional from the Qin and Han dynasties, and although they did recruit people during wars, they almost did not undertake combat tasks, and were often responsible for auxiliary work such as transporting grain and grass, assembling equipment, and building camp tents. Because the discipline and morale of the civilians could not be compared with that of the regular army, even if they fought a good battle and abused vegetables, it was possible to send the people to the front only as a last resort, except for urban warfare (siege and defense). A professional army does not produce, so it only consumes but does not produce.

This requires that there must be stable productivity and a large rear in order to provide them with sufficient logistical support, so there is a saying that the outside must first be safe. At least when it comes to making sure that foreign enemies don't hit your home, this argument still makes sense.

Therefore, the first task in the early days of the Han Dynasty was to clean up the mess left by the previous dynasty, and the treatment of foreign enemies could only be coaxed a little first, coaxing the Huns and making them think that the Central Plains would not attack them directly. At the same time, it was also necessary to ensure that the border was relatively stable, at least so that the Huns could not penetrate deep into the hinterland of the Central Plains. Until the time is ripe and the national strength is restored, they will be given another blow.

Starting with Liu Bang and continuing to Liu Che, this process of regaining strength lasted for three generations.

Because the Han Dynasty army was not good in combat effectiveness, there were no wise generals to lead them into battle, and they could not defeat the fierce Xiongnu, while the Qin army had many famous generals and high military quality, and the soldiers had strong combat ability.

Because the army of the Qin Dynasty was very strong, and the Xiongnu did not form combat effectiveness, they were able to defeat the Xiongnu, and in the Han Dynasty, the Xiongnu formed a great unity and were strong, so the Han Dynasty could not defeat the Xiongnu.

Because the strength of the Xiongnu in different periods was different, the Xiongnu were still just a plate of scattered sand during the Qin Dynasty, and by the time of the Han Dynasty, the Xiongnu had been unified by Maodun and built very strong.

The strength of the Xiongnu during the Qin Dynasty was not too strong, while the Xiongnu were already very strong in the Western Han Dynasty.

Because in the Qin Dynasty, the Xiongnu were simple-minded and had developed limbs and could only do brute force, and in the Han Dynasty, there was a traitor who came up with a strategy, and the Huns were not so easy to fight.

Because the Xiongnu did not unify and form forces during the Qin Dynasty, they could be defeated during the Qin Dynasty, and in the Han Dynasty, there were leaders who realized the unification of the Xiongnu, and their strength was very strong, so the Han Dynasty was very afraid of the Xiongnu.

Because during the Qin Dynasty, the national strength was very strong, and the Xiongnu were only a small tribe at that time. In the Han Dynasty, the Xiongnu tribes fought in the south and the north, and gradually unified the small tribes and became strong.

Because the strength of the Xiongnu in different periods was different, the Xiongnu during the Qin Dynasty were still scattered, while the Xiongnu in the Han Dynasty were already powerful Xiongnu after being unified by Maoton.

I don't think so. It should be a question of the strength of the Xiongnu, the Han army and the Qin army are the same.

It is not that the Qin army is stronger than the Han army, but because the generals of the Qin army are powerful, and they govern the soldiers under their command well.

No, this is because the Qin army was relatively advanced at that time, and it had a great advantage in the number of people at that time, so it was able to easily defeat the Xiongnu and achieve victory.

In fact, judging from the overall situation, it is not good for Liu Bang, and he is too reckless. As soon as the Han Dynasty was established, it was already scarred, and the army was already exhausted. Second, Liu Bang destroyed many generals who could fight well when he founded the country, and although his level of fighting was not bad, he was really inferior to those generals.

And Qin Shi Huang was different at that time, the army was strong and there were good generals, although he could not defeat the Xiongnu, he could still do it if he repelled it.

These examples were very prominent in the time of Emperor Wu of the Han Dynasty, when the country was strong and there were good generals to command, so he naturally defeated the Xiongnu.

So the comprehensive reason is that Liu Bang was reckless.
