After the Qin king Yin Zheng unified the world, after ascending the throne and claiming the throne, he sent the general Meng Tian to lead 300,000 Great Wall troops north to attack the Xiongnu, and the Xiongnu had no power to fight back, easily recovered the Hetao region, and built the famous Great Wall, but in the early Han Dynasty, the Xiongnu revived, Liu Bang personally led 320,000 troops to attack, but he almost lost his life, resulting in the next sixty years can only use the policy of peace and affinity to appease the Xiongnu and maintain a fragile peace, so the reason for not being able to defeat the Xiongnu is that the Qin army is too fierce or the Han army is incompetent?
First of all, let's look at the situation of the Xiongnu at that time, during the Qin Dynasty, the Xiongnu belonged to the belly and back of the enemy, Donghu and Yueshi were very powerful, and had already made the Xiongnu anxious, at this time, Mengtian's 300,000 troops seemed to be the last straw that crushed the camels, so the Xiongnu behaved so vulnerable; and in the last years of the Qin Dynasty, the world was in chaos, and no one in the Central Plains cared about the Xiongnu, so they quietly killed back under the leadership of Tou ManDan Yu and were able to recuperate.
Secondly, the combat effectiveness of the Qin army is strong, after all, the reason why the Qin army can sweep most of the six countries is also relying on strong combat strength, and the source of motivation for this combat effectiveness is the military merit policy of the Qin state, and the heads of the Serious Xiongnu in the Qin army are the ladders for promotion and wealth, so the Qin army is particularly brave when it rushes to kill, and it can really be called the division of tigers and wolves.
Third, the Xiongnu produced a werewolf (a little more than the fierce people), that is, their leader Mo Dun Shan Yu, he was originally the eldest son of Tou Man Dan Yu, and deserved to succeed to the throne, but Tou Man Shan Yu married after the favor of the Fu clan, Ai Wu and Wu wanted to make this Fu clan's son the prince, and designed to kill Mo Dun, and as a result, the astute Mo Dun Star Night ran away to escape a disaster, and finally Ming Di killed his father, seized the position of Shan Yu, and then destroyed more than twenty countries including Dong Hu, Driving Yue Clan, Zheng Lou Lan, etc., basically ruled the Western Regions. It was also he who created the Siege of Bai Deng, almost killing Liu Bang.
Finally, when it comes to the combat effectiveness of the army, the troops of the early Han Dynasty are indeed inferior to the troops of the late Qin Dynasty, after all, the troops of the early Han Dynasty basically belong to the peasant uprising, and there is still a little gap between the well-trained Qin Dynasty armed forces, then some people will say, then how can the Qin Dynasty still let a group of peasants be destroyed, you must know that the Qin Dynasty has lost the hearts of the people at that time, and the last main force was destroyed by Xiang Yu, the king of Western Chu, which is that a mountain is higher than a mountain, which is actually the trend of the times.
Moreover, the strength of the Xiongnu at that time was greatly reduced in internal and external troubles, and the Xiongnu soldiers at this time were strong and strong, and they could not be said in the same day.
Sun Tzu said that there are five very important points in fighting a war, that is, "Dao Tiandi General Law", of which this Tianhe general is not very dominant, first of all, the heavens are the general trend, at that time the Central Plains for many years of war, has been injured inside and outside, Liu Bang traveled to find four horses of the same color are difficult, and secondly, the general, although Liu Bang has a certain military talent, but in front of The Mao Dun Shan Yu is still a little worse, and after all, the age is not small, the horse lost its front hoof, fortunately, the organic spirit ghost Chen Ping calculated to bribe Mo Dun Shan Yu Yu to save his life.
In general, it is not that the national army is incompetent, but that the enemy is too cunning, but fortunately, our country has had a quality of concealment since ancient times, and the gentleman hides the instrument to wait for the time to move, and the Taoguang is obscure for sixty years, and finally exhales and raises his eyebrows when Emperor Wu of the Han Dynasty, defeating the Xiongnu in one fell swoop and promoting the prestige of our Great Han Dynasty.
Left behind the sentence that is still deafening and deafening, "Those who commit crimes against strong men will be punished from afar!" ”
