The Qin army was invincible when it destroyed the Six Kingdoms, why was it so vulnerable when fighti

First of all, the times are different. At the end of the Warring States period. The seven countries coexisted side by side, the wars continued, and the people longed for reunification. By the time of Qin Shi Huang's death, Qin II's rule was brutal, and the people of the world hated it. They all yearn to overthrow the tyrannical rule of the Qin Dynasty.

In the last years of Qin, the Qin Dynasty was under the rule of Zhao Gao. The second was incompetent, and almost all the generals of the Qin Dynasty who could fight well were ostracized, so that Chen Sheng led an army to besiege Xianyang, and Qin had no army to respond to the battle, and later Yan Han temporarily organized 700,000 prisoners of Lishan to meet the battle in a hurry, and promised to remove them from service, so as to reluctantly repel their attack. In fact, Yan Han is also a talent, most of the wars in the late Qin period were mostly led by him, as the saying goes, a group of soldiers and bears will be bears, Chu and Qin have always been enemies, in the last years of the Warring States Period, King Chu Huai was imprisoned by Qin State, and died in Qin, which is a great shame for Chu, it can be said that Chu hates Qin to the bone, and Xiang Yu is brave, can bring a certain confidence to Chu, it can be said that Qin lost not the army but the people.

Although the Qin army was numerous, it had lost its military spirit. The army lost its fighting spirit after the death of Qin II. Although Xiang Yu has few soldiers, he is broken. Either die or defeat the Qin army. Fight to the death. Naturally breakable.

Xiang Yu, Wen Taowu is very shrewd, he is a very powerful figure in history, and it is normal to defeat the Qin army.

Because Xiang Yu was a brave and resourceful general, and his power was very strong at that time.

When the two armies meet, the brave wins, and Xiang Yu's courage is the key to victory.

It is normal to be strong and good at fighting, and to be brave.

Xiang Yunyou's very strong military force, and Xiang Yu himself is also the overlord of Western Chu, with a high popularity and five.

Why Xiang Yu can break his youth, this is because he is brave.

At the end of the Qin Dynasty, Xiang Yu broke the cauldron in the battle of Julu and fought an earth-shattering decisive battle with the Qin army.

This battle was the most critical battle to destroy Qin, and it has become a classic case and is praised. Later generations of some people who were not good at learning and skills, such as Ma Tan and Zhang Lingfu, thought that this battle was all thanks to the plan to break the cauldron and sink the boat to stimulate combat effectiveness, so they were able to defeat the Qin army that had swept Liuhe in one fell swoop, so they painted a gourd, set up a desperate situation, and tried to win a big victory, but it backfired, not only failed to win but lost the teacher, and laughed generously.

Taking history as a mirror is to know what it is, why it is true, and to dispel the idea that some soldiers do not care about the overall situation, are whimsical, and go to war rashly, so as not to follow in their footsteps and cause irreparable harm.

1.Zhang Han did underestimate Xiang Yu and failed to make a correct judgment.

2.Xiang Yu's military talent is very high.

I think that if history can be returned, Zhang Han will definitely win.

The first question: Zhang Han uses prisoners, and his combat effectiveness is different from the past. And the Battle of Changping was not an equal battle, Zhao Kuo talked about it on paper.

The second question: not only fear Qin, but also sit on the mountain and watch the tiger fight, and then make a choice after seeing the situation clearly. The princes were originally separated from morality, which is the same reason as the anti-Dong alliance in the late Eastern Han Dynasty.

These are the root causes.

I think there are three reasons for this.

First. The Qin army lost all the hearts of the people, although the strength of sweeping the six countries back then was still there, but it was only the end of the strong crossbow.

Second. Xiang Yu is also a military genius, and the Jiangdong soldiers under him are also brave!

Third. is the most important point, Xiang Yu himself has the courage of ten thousand people, and his personality is murderous, which makes Qin soldiers discourage.

That's it, the landlord's reward of 0 points caused me to type so many words in vain.

In the last years of the Qin Dynasty, the world was in turmoil, the princes were divided, and the warlords were fighting. In 208 BC, Wang Xie of Zhao was besieged by an army of 200,000 led by the Qin general Wang Li in Julu (now Pingxiang, Hebei), and in desperation, he sent an envoy to ask for help from King Huai of Chu. At that time, the Qin army was very strong, and no one dared to go forward to meet it.

Xiang Yu took the initiative to ask for revenge for the Qin army's killing of his uncle Xiang Liang, so King Chu Huai took Song Yi as the general, Xiang Yu as the second general, and Fan Zeng as the last general, and led an army of more than 60,000 to relieve the difficulty of Julu. After the Zhao army advanced to Anyang (now southeast of Caoyang, Shandong), Song Yi was intimidated by the arrogance of the Qin army and stayed for 46 days and did not dare to advance. Xiang Yu denounced Song Yi for his cowardly behavior and killed him.

King Huai of Chu then made Xiang Yu a general, and ordered the two rebel armies of Yingbu and General Pu to also be under his command. Xiang Yu first sent his generals Yingbu and Pu to lead 20,000 people as the vanguard to cross the Yellow River and cut off the grain transportation channel of the Qin army. Then, Xiang Yu personally led all the main forces to cross the river, and ordered the soldiers of the whole army to break the cauldron and sink the boat, each carrying only three days' dry food, in order to show the determination to fight to the death.

Xiang Yu said to the soldiers: "We will send troops to Julu this time, there is no advance or retreat, and within three days, we must defeat the Qin army." Xiang Yu's determination and courage greatly boosted the morale of the soldiers.

The morale of the Chu army was invigorated, and they fought bravely to the death, won nine battles and nine victories, and defeated the Qin army. At this time, Qi, Yan and other reinforcements also rushed out of the camp to help the battle, and finally captured Wang Li, the commander of the Qin army, and killed his deputy general, so that the dilemma of Julu was solved.

Julu was a major battle in the last years of the Qin Dynasty, when the famous anti-Qin general Xiang Yu led the Chu rebel army to annihilate the main force of the Qin army Zhang Han and Wang Li. Xiang Yu's army suffered heavy losses due to the defeat of the Qin army, while Xiang Yu established his leading position among the rebel armies.

Xiang Yu fought with the main force of the Qin army in Julu, won nine battles and nine victories, and defeated the Qin army.

First of all, this battle was a battle in which the advanced productive forces replaced the old ones, and from a philosophical point of view, the Qin army was bound to lose; Secondly, the Chu army at that time represented the interests of most of the masses and was supported by the masses, and from a political point of view, the Qin army was bound to be defeated; Thirdly, the combat effectiveness of Xiang Yu's troops was very strong, and the combat effectiveness of the Qin State at that time had declined sharply compared with the unification of the Six Kingdoms, and the Qin army was bound to be defeated from a military point of view.

In the early days, large-scale wars still depended on generals, and the Qin Dynasty still had the strength of the army at that time, and it was only until Qin II that the army had been participating in counterinsurgency, so the combat effectiveness was no problem, and the key was that the generals were incompetent.

You tell me who fought Xiang Yu in the same period except Han Xin.

That's not the main force, it's made up of slaves who repair the Emperor's Mausoleum.

1. Due to Zhao Gao's autocratic power, Hu Hai's mediocrity caused the soldiers to be centrifuged.

2. At that time, the old nobles of the six countries in various places launched rebellions, and smoke broke out everywhere, and the Qin army was struggling to cope 3. In the Battle of Julu, the Qin army formed was composed of a large number of Lishan prisoners and slaves, although it defeated many rebel armies, but it also killed 10,000 enemies and injured 8,000 itself.

4. Zhao Gao's suspicion of Zhang Han, the general of the Qin army, made Zhang Han unable to concentrate on the enemy.

5. Xiang Yu's troops belong to the new force and have strong combat effectiveness.

In fact, the reason is very simple, because the military ability of the commanders of the Qin army is not as strong as Xiang Yu, the number of troops in the era of cold weapons is important, and the Qin army has an advantage in this point, but if you want to defeat the enemy in the war, the commander's tactical and strategic mind is more important, compared to Xiang Yu, the commander of the Qin army is too mediocre, although Xiang Yu's army is greatly inferior in numbers compared to the Qin army, but Xiang Yu adopts very flexible tactics, when the Qin army is fierce, Xiang Yu can ensure that his retreat is intact and preserved, When the Qin army was tired and rested, Xiang Yu would launch a surprise attack on it to effectively kill and injure the Qin army, which led to the fact that although the Qin army was large, it was passively beaten, and the time dragged on for a longer and longer time, and the soldiers of the Qin army found that the war was fighting more and more endlessly, as if there was a bottomless pit, and there were more and more sick wounded, and the morale and combat effectiveness were reduced to the extreme, and Xiang Yu's Chu army, due to the cruel oppression of the Qin high-level for a long time, was full of revenge and anger, and won more and lost less under the leadership of Xiang Yu, and marched all the way.
