After the "Battle of Changping", King Xiaocheng of Zhao, in order to negotiate peace with the State of Qin, originally promised to cede the six cities to the State of Qin, but in the end he reneged on his promise, So King Zhaoxiang of Qin once again raised an army to attack Zhao and besieged the Zhao capital Handan, and King Xiaocheng of Zhao then asked Wei Chu for help, Wei Guoben had already sent troops, but under the threat of the State of Qin, he did not move, xin Lingjun was impatient, he stole the soldier's charm, killed the Wei general Jin and seized the military power, and then led the army to join forces with the State of Chu to defeat the Qin army, defusing the danger of the fall of the State of Zhao.
As the two major powers of the late Warring States period, Qin Zhao's "Battle of Changping" can be said to have directly affected the historical trend at the end of the Warring States period, in which the Zhao State lost as many as 450,000 troops, directly suffering heavy losses, and the Lord of the Qin State, Bai Qi, intended to directly attack Handan and destroy the Zhao State, but because fan Sui was bribed by han Zhao's emissaries, King Zhaoxiang of Qin finally ordered a strike and peace, and the Zhao State was able to avoid the destruction of the country.
At the time of the Qin and Zhao negotiations, it was agreed that the State of Zhao would cede the six cities to the State of Qin, but King Xiaocheng of Zhao, under the advice of his chancellor Yu Qing, finally decided not to fulfill the contract, but instead formed an alliance with the State of Wei, and at the same time gave lingqiu to the State of Chu Chun Shenjun Huang Xie, in order to befriend the State of Chu and begin to repair relations with Korea, the State of Yan, and the State of Qi.
Of course, King Xiaocheng of Zhao also knew that if he refused to cut off the land, then the Qin state would inevitably send troops to attack, so while actively contacting other countries externally, he was also actively preparing for war internally.
King Zhaoxiang of Qin, seeing that the State of Zhao had breached the contract and refused to cede the Six Cities, instead joined forces with the Eastern States to deal with the State of Qin, so in September of the fifty-sixth year of the Reign of Zhou Zhao (259 BC), he sent the Fifth Master Wang Ling to lead an army to the Zhao capital handan.
After the "Battle of Changping", there was no danger to the west of Handan
Since there was no danger to defend west of Handan after the "Battle of Changping", the Zhao state had to shrink all its troops to defend Handan, and Zhao Sheng, the king of the Zhao Xiang Plain, also scattered his family wealth to recruit soldiers, and even incorporated his wives and concubines into the army, while the military and people of the Zhao state hated the Qin state to the bone, and also actively participated in the armament war, and for a time Handan simply became a military city.
Qin and Zhao fought fiercely in Handan for several months, and the Qin state lost five schools of soldiers and horses (about 40,000 people) and it was still difficult to capture Handan, and after the failure of Qin Zhaoxiang to use Baiqi, he had to send Wang Gong to replace Wang Ling as a general, and added 100,000 troops to continue to besiege Handan. Under the resolute resistance of the military and people of the Zhao state, the Qin army suffered heavy losses and still could not advance. At the same time, Bai Qi refused to lead his troops to battle, and was eventually forced to commit suicide.
Although the Zhao army, under the command of Lian Po, withstood the attack of the Qin army and inflicted heavy casualties on the Qin army, because the Zhao state had suffered heavy losses in the "Battle of Changping" and the national strength had not yet recovered, the grain in Handan city was soon exhausted, and the Qin state sent Zheng Anping to lead 50,000 reinforcements and carried a large amount of grain to support Wang Gong, and King Xiaocheng of Zhao had to send emissaries to Wei and Chu for help.
In the eighth year of King Xiaocheng of Zhao (258 BC), Zhao Sheng, the Prince of Pingyuan, was ordered to send envoys to Wei and Chu, because his wife was the sister of Xin Lingjun of the State of Wei, so Pingyuan Jun sent emissaries to ask for help from the State of Wei on the one hand, and on the other hand, he sent a visitor to visit the State of Xin Lingjun and ask him to send troops to the State of Wei, while he himself personally went to the State of Chu to ask for help.
After Pingyuan Jun arrived in the Chu state, with the help of Mao Sui, he successfully persuaded the king of Chu Kao Lie, and the Chu state sent 100,000 troops to rescue the Zhao state. After receiving a request for help from Pingyuan Jun, The Xinling Emperor Wei Wuji repeatedly persuaded The King of Wei to send troops, and launched a comprehensive lobby for the King of Wei through guests and discerners, and the King of Wei finally decided to send Jin To lead 100,000 Wei troops to rescue Zhao.
After learning that the two countries of Wei and Chu sent troops, because the Chu state was far away and the threat to the Qin state was small, king Zhaoxiang of Qin immediately sent emissaries to the state of Wei to threaten the king of Wei An, "If any of the princes dares to rescue the state of Zhao, after the state of Qin defeats the state of Zhao, it will definitely attack and save the country of Zhao." Fearful, King Wei ordered The Jin army to temporarily stop at Yu and make a decision after the battle was clear.
When the Xinling Emperor Wei Wuji learned of this, he was so distraught that he, under the persuasion of Hou Ying, turned to King Wei's favorite concubine Ru Ji. Because Wei Wuji had helped Ru Ji avenge her father's murder, Ru Ji was extremely grateful to Xin Lingjun, and without the slightest hesitation, she agreed to Wei Wuji's request and stole a soldier charm from the wei king's bedroom and handed it to Wei Wuji.
Before Wei Wuji set out, Hou Ying went to see Xin Lingjun again and said to him, "General Will be outside, and Jun Ling will not be affected." If Jin despised the soldiers, but still refused to hand over the army, and still asked the King of Wei for instructions, then things would be dangerous. My friend Zhu Hai is a strong martial artist, and I can take him with me. If Jin despises obedience, it is best; If you don't obey, you can let Zhu Hai kill him! ”
After Wei Wuji arrived at Yecheng, he handed over the soldier's charm to Jin For investigation, and although there was no problem with the soldier's charm, Jin's heart was still suspicious, so he said to Wei Wujie, "I lead a hundred thousand troops stationed at the border and undertake the important mission of the country. Why is it that you are only sent alone to replace you now? Zhu Hai saw the situation and decisively killed Jin with an iron mallet, and Xin Lingjun took control of the military power.
After Wei Wuji took over the army, he selected 80,000 elite soldiers from it and rushed to the Zhao state of Handan at the same time. At the same time, in order to alleviate the pressure on the city defense, Zhao Sheng, the Prince of Pingyuan, recruited three thousand daredevils and launched a surprise attack on the Qin army under the leadership of Li Tan, the son of Sheren, and the Qin army was defeated without any defense and forced to withdraw 30 miles.
In December of the 58th year of king Zhou Zhao (257 BC), reinforcements from Wei and Chu arrived on the outskirts of Handan and immediately launched an attack on the Qin army. The Defenders of the State of Zhao saw the situation and also quickly organized their troops to go out of the city to counterattack. Under the attack of the three kingdoms, the Qin army was defeated, Wang Gong had to lead the remaining Qin army back to Fencheng, Hedong, and Zheng Anping led his army to retreat to Xinliang City, and the siege of Handan was lifted.
Two months later, the three kingdoms of Han, Zhao, and Wei reorganized their combined forces and launched a counterattack against the Qin army, directly approaching The city of Fencheng, where Wang Gong was located, with the intention of completely blocking the eastward advance of the Qin state. Unexpectedly, Wang Gong unexpectedly took the initiative to attack from Fencheng, preemptively attacked the coalition forces, beheaded Liu Qianyu, the coalition forces were defeated and fled south, Wang Gong chased all the way to the Yellow River, and as a result, more than 20,000 people of the coalition forces drowned in the river in a panic.
At the same time, another Zhao army took advantage of Wang Gong's main force to attack Fencheng, but was immediately attacked by Wang Gong's Hui army, and then Wang Gong captured Zhao Guoning Xinzhong (present-day Anyang). The following year, the combined forces of Han, Wei, and Chu counterattacked Ningxinzhong, and Wang Gong was forced to withdraw. Zhao Guole and Qingshe then led an army to attack Zheng Anping in XinliangCheng, and Zheng Anping was besieged and eventually surrendered to Zhao.
The "Battle of Handan" thus ended, in which the Qin state lost more than 200,000 troops, but did not gain anything, resulting in the bankruptcy of the Qin state's plan to carry out a comprehensive attack on the six countries, and greatly delayed the process of destroying the six kingdoms.
