After the Battle of Changping, the State of Qin actually had two excellent opportunities to destroy the State of Zhao. One was just after the Battle of Changping, and the other was at the Battle of Handan.
The first chance just after the Battle of Changping
After the Battle of Changping, the Zhao state was greatly weakened, and there were only a few tens of thousands of armed forces left in the country, and the Qin general Bai Qi intended to seize the opportunity to attack the capital of the Zhao state, Handan, and then destroy the Zhao state, but this plan was rejected by King Zhaoxiang of Qin.
The reason why the King of Qin rejected this plan was that he was still immersed in the joy of changping's great victory, believing that the Zhao state was already in name only, and his arrogance was growing. Second, on the grounds that Hou Fan Sui was jealous of bai qi' merits, on the grounds that the Qin army should be rested due to fatigue, he suggested that Korea cede Yuanyong and Zhao Guo to the six cities to please peace, catering to the will of King Zhaoxiang of Qin and buying time for the six kingdoms to join forces against Qin.
Although Han Zhao was greatly defeated, but the matter of cutting the city, the Zhao State, who obviously had a strong sense of self-esteem, would not agree, and sure enough, the Zhao State did not cede the six cities in default, but instead joined forces with the Eastern States to deal with the Qin State, in an attempt to achieve the shame of a snow and a long peace, and the King of Qin Zhaoxiang became angry and embarrassed, and eventually led to the Battle of Handan.
Therefore, the first time that the State of Qin failed to destroy the State of Zhao, there were factors of the pride and carelessness of the King of Qin, and there were also reasons for the discord between the civil and military forces within the State of Qin.
Second chance at the Battle of Handan
On the eve of the Battle of Handan, King Zhaoxiang of Qin intended to let the famous general Bai Qi take command and continue to write about the glory of the Battle of Changping, but Bai Qi was still complaining because of his previous unhappiness with Fan Ju, so he refused to take command of Zhao under the pretext of illness, and the King of Qin was helpless, so he changed the five masters Wang Ling to lead a 250,000-strong army to kill the Zhao capital Handan.
Looking at the side of the Zhao State, the King of Zhao was defeated in the Battle of Changping because he did not listen to Lian Po's words, so he regretted it very much, and zhao Guo reused the veteran general Lian Po in the Handan Guard Battle, and vigorously recruited troops in the country to prepare for the battle.
In addition, the envoys of the State of Zhao also ran to various countries to take advantage of the interests of Chen and requested a joint resistance to Qin, although the countries were afraid of the division of the Tiger and Wolf of the State of Qin, but they also knew the truth of the cold of the lips, especially the two great powers of Wei and Chu, which were closest to the State of Qin, when facing the state of Zhao being suppressed by more than 200,000 Qin troops, each sent 100,000 elite troops to support the State of Zhao, and the 100,000 Zhao army led by Lian Po should be combined with the outside world, and finally defeated the Qin army, the casualties of the State of Qin exceeded 200,000, and after this war, the State of Zhao continued for more than twenty or thirty years. Among them, Zhao Guo also had a brief ZTE.
It can be seen that the second time that the Qin state failed to destroy the Zhao state, there were factors of civil and military discord within the Qin state, there were reasons for the stubborn resistance of the Zhao state, and more importantly, the eastern countries realized the major threat of the Qin state and re-entered the alliance, so they defeated the Qin army in Handan, and extended the life of the Zhao state for several decades.
