The Battle of Changping was a war delivered to the doorstep of his home, and Zhao Guo could not hide even if he wanted to. Many friends felt that Zhao Guo was greedy for temporary interests and accepted the Shangdang County offered by Feng Ting, which was tantamount to opening Pandora's box. However, once we carefully analyze the situation at that time, we will find that at that time, Zhao Guo had no choice but to take over the party and devote all the strength of the whole country to resist Qiang Qin. This war is undoubtedly a gamble, but it is a battle that must be gambled.

After the three families were divided into Jin, Zhao, Wei, and Han were still known as the "Three Jins", and although Zhao and Wei fought many battles for hegemony, the pace of the three families in the Warring States period was basically the same. However, in the late Warring States period, the Qin state became increasingly powerful, and most of them fought against each other in a row of horizontal and horizontal confrontations, and constantly encroached on the east. Among the seven warring states, South Korea was the weakest and bore the brunt of it.
During the Warring States period, Shangdang County was not under the jurisdiction of one country, but was divided up after the three families were divided on the basis of the old counties of the original Jin Dynasty. At present, the academic community can affirm that Han and Zhao both had Their own Shangdang Counties, and the Wei State may have also had Shangdang Counties. According to the Qing Dynasty Cheng Enze's "Examination of National Policies and Geographical Names":
The earth is extremely high, and the heavens are the party, so it is called the party.
”
Shangdang County is not only easy to defend and difficult to attack, but also located at the crossroads of transportation, and is a key area connecting the states of Qin, Zhao, Han, and Wei, and once the Qin state occupies Shangdang, it can enter the hinterland of the Zhao state, and even choose the pass to cross the Taihang Mountains and take Handan directly. It can be said that the Han Party is the key to the relationship between the Three Jins, especially the security of Zhao Guo.
Qin is strong and Han is weak, and Han Shangdang County has become a lonely place hanging outside the mainland. Unable to defend, South Korea wanted to sacrifice its superiors to suspend the Qin offensive. However, Han Shangdang taishou Feng Ting was unwilling to be slaughtered by others, and was selfish and gave all the land of a county to Zhao. At that time, among the three Jins, Zhao Guo was the strongest, and even had a great influence in the Six Kingdoms of the East. At the critical moment, Feng Ting could only compete with the Qin army if he was dependent on Zhao Guo. Similarly, this hot potato, Zhao Guo also had to pick up.
The change of hands in Shangdang County is tantamount to "one woman hiring two families". What followed was the battle between Qin and Zhao in Changping. When the two tigers fight each other, there will be an injury, and the rest of the countries will also look at the fire. The reason why they chose to watch from the sidelines was undoubtedly to use this battle to weaken Qin and Zhao. It can be said that a strong Qin or a strong Zhao is very unfavorable to the other five countries.
But what no one expected was that hundreds of thousands of soldiers and generals of the Zhao Army were all killed in Changping. After the victory of the Qin state, the eastern states were shocked, but it was too late. However, after that, the State of Wei also knew the truth of the cold of the lips, after the Battle of Changping, the Qin army besieged Handan, and After repeated consultations, Wei, Zhao, Chu, and Han finally attacked Qin again and solved the siege of Handan.
Finally, let's reflect on the Battle of Changping: in 263 BC, King Xiaocheng of Zhao sent the veteran general Lian Po to lead an army to garrison Changping, but because the Zhao army was weak and slightly inferior, after several battles were lost, Lian Po decided to stick to no battle and hold the Qin army. However, hundreds of thousands of soldiers were in the front, and it was difficult to supply grain and grass in the rear, and the economy of the Zhao state was about to be dragged down. At the critical moment, the Qin army used a divisive strategy, and in desperation, Zhao Guo could only use Zhao Kuo, hoping to make a quick decision.
The historical Zhao Kuo is by no means a generalist who can only talk on paper, and he is brave and resolute, even if he is not as good as Bai Qi, he is also a respectable general, and finally died on the road of the charge. The fiasco of the Zhao state, in the final analysis, was that the comprehensive national strength was inferior to that of the Qin state, and it was even difficult to gather heavy troops to rescue in the later stages of the war, and it was difficult to break through the blockade of the Qin army. It can be said that in the case of the large army being trapped and the grain and grass being poor, even if it is used again, it is difficult to reverse the defeat.
