Qin empire 2

■ Combination strategy

Under the new situation of balanced strength and fierce war, every vassal state pays attention to the strategy of "uniting the vertical and Lian Heng", which is also a remarkable feature of this historical stage. The so-called "vertical integration" is to unite many weak countries to attack a strong country; The so-called Lian Heng is to unite a powerful country to attack other weak countries.

During the Warring States Period, the State of Qin became prosperous rapidly through Shang Yang's reform, and Qi was also a powerful country in the East at this time. In this way, the two great powers of the East and the West confront each other and other weak countries coexist. "He" and "Lian Heng" appeared in this complicated situation.

Gongsun Yan, also known as Shou, was a great architect of Qin State. Later, Zhang Yi defected to King Qin Huiwen. The king of Qin admired Zhang Yi very much and worshipped Zhang Yi as Qin Xiang. But Zhang Yi and Gongsun Yan have different views. Zhang Yi advocates "Lian Heng" and Gongsun Yan advocates "combination". Qin Huiwen appreciated Zhang Yi and abandoned Gongsun Yan.

In a fit of pique, Gongsun Yan came to Wei from Qin.

After Gongsun Yan came to Wei, he was quickly taken seriously by Wei. In 3 19 BC, he became Wei Xiang. He knew that Wei was not as powerful as Qin. In order to deal with Qin and Zhang Yi's "Lian Heng" policy, he put forward the strategy of "combination". He called on the five countries to unite. These five countries are Wei, Zhao, Han, Chu and Yan.

Because these five countries are relatively weak, they can't fight against Qin alone, so Gongsun Yan hopes to strengthen its strength and compete with it through joint efforts.

However, many people are distracted. Chu and Yan did not send troops to fight, and Wei, Zhao and Han also had their own plans. Therefore, in the First World War in Xiuse (now Yuanyang, Henan Province), Qin Jun won a total victory and wiped out more than 80,000 enemy troops.

Zhang Yi suggested Qin Huiwen's kingly way: "Master, Sanjin is not yet strong, so we should attack it with victory."

King Qin Huiwen attacked Sanjin again. South Korea sent all the princes to Qin as hostages and surrendered. Ye Zhao promised to make peace, and Wei was interfered by Qin.

Qin became more powerful, and "unity" not only did not defeat Qin, but inspired Qin's fighting spirit.

After Gongsun Yan failed, Su Qin appeared.

Su Qin is from Luoyi. He and Zhang Yi are classmates and good friends, but their strategies are different. Su Qin also advocated "union".

After studying hard for the second time, Su Qin first went to Yan State, where he was treated and reused by Yan.

He said to the king, "Master, Qin is the most powerful country today, and sometimes it has the ambition to annex other countries. We should unite with these weak countries to resist the state of Qin. Only in this way can peace be guaranteed. " So Zhao, Han, Wei, Qi and Chu joined forces to attack the State of Qin. However, due to poor organization, the Coalition forces have never launched a major attack, and the result has always been "nothing."

■ Lian Heng's strategy

Facing the allied forces, the king of Qin asked Zhang Yi how to confront the enemy.

Zhang Yi said, "Master, at present, Qi and Chu are both powerful countries in the allied forces. As long as they are separated, everything else can be solved. "

So Zhang Yi was ordered by the King of Qin to go to Qi and Chu.

Zhang Yixian went to Chu, bribed Chu Huaiwang's favorite Shanxi merchants, and then went to see Chu Huaiwang.

Zhang Yi said to Chu Huaiwang, "If Chu and Qi break off diplomatic relations, Qin is willing to return the 600-mile-long land to Chu and make friends with you."

Le Shang, my favorite minister, also stated the advantages of forming an alliance with Qin, and he readily agreed despite the opposition of other ministers.

Chu and Qi broke off diplomatic relations.

Chu Huaiwang sent an emissary to see the king of Qin and wanted him to come back to do business, but he was refused. Zhang Yi took the map and said, "Your king heard wrong. I mean give your six miles of fief to Chu, not Qin's six hundred miles. "

When the emissary returned to Chu, he said from beginning to end that Chu Huaiwang was very angry. He immediately sent troops to attack the state of Qin. The State of Qin was prepared and defeated the State of Chu.

Chu Huaiwang unwilling, once again sent hundreds of troops against the state of Qin. Qin joined forces with Qi, defeated Chu, and took away 600 miles of land in Hanzhong. In desperation, Chu had to make peace. The strength of Chu was greatly weakened and never recovered.

After the weakening of Chu, Chyi Chin confronted each other, and the vertical and horizontal relations between Su Qin also collapsed.

In 286 BC, due to the civil strife in the Song Dynasty. Qi wants to take this opportunity to strengthen its own strength and expand its territory. So Qi sent troops to attack Song.

Song Guojun saw that Song was going to die and ran to Wei, and there was a conflict between Qi and Wei. Qi finally destroyed Song, and Song Guojun and Song Kangwang died of grief and indignation.

The destruction of the Song Dynasty by the State of Qi aroused strong dissatisfaction from other vassal States, all of which wanted to rise up and attack, but they dared not act rashly without leaders.

Zhang Yi said to the king of Qin, "Master, Chu has been weakened now, and if Chyi Chin's confrontation is not weakened, it will certainly pose a threat to us in the future. Now the destruction of the Song Dynasty in sending troops, Qi is unpopular, and the vassal States are also very dissatisfied, but they dare not send troops easily. If we stand up at this time, organize ourselves and unite with other countries to attack Qi, we will certainly defeat Qi's army. Then we can dominate alone. "

In 285 BC, the king of Qin and the king of Chu met in Wan, and said to the king of Chu, "Now Qi is going against the sky and heartless, and it is bound to take the opportunity to destroy your country in the future." Although Chu had conflicts with Qin, when he saw Qi attacking Song, he also wanted to make friends with Qin, so he agreed to Qin's invitation.

The king of Qin convinced the king of Zhao with the same words.

In 284 BC, the king of Qin met with Wang Wei and Han Wang and reached an agreement.

In 284 BC, Qin, Yan, Han, Zhao, Wei and Chu jointly attacked Qi, and defeated Qi in Jixi.

Since then, the State of Qi has been devastated, and only the State of Qin has stood out from the crowd and made preparations for future reunification.
