In 25 1 BC, Zhao Wei-wang celebrated his birthday, and the prince sent Li Fu, the prime minister, as an envoy to Handan with 500 gold as a birthday present. At that time, Zhao had just experienced the battle of Changping and the siege of Handan, and its national strength was not as good as before. Most of the able-bodied men died in battle, and the proportion of the domestic population was seriously unbalanced. After Li Xiang of Yan visited Zhao, he came to a conclusion: Zhao is vulnerable, and Yan can seize territory!
After returning home, Li Du reported to Yan:? Most of Zhao's able-bodied men died in the battle of Changping, leaving only orphans who did not grow up. Now is the best time to kill Zhao. ? Since the death, Yan has been lacking in military affairs, because there are not many neighboring countries and foreign enemies invading, unlike countries located in the Central Plains such as Korea and Wei, which have always maintained a strong sense of crisis. Now that Zhao is weakened, Yan is not thinking about how to fight against Qin with other countries, but wants to take the opportunity to make a fortune. Thus, the unification of Qin is inevitable.
The prince found Le Yi's son, Le Jian, and wanted to hear his advice. Music room objection:? Zhao is located in the land of four wars, and all the people are soldiers. Zhao cannot be attacked. ? The prince said disapprovingly: I sent twice as many troops as Zhao. Isn't that enough? ? He said without thinking:? No ? The prince said again:? Then I'll send five times as many troops, that's all. ? Music room or insist on: No ?
This made the prince very angry, thinking that the piano room was originally a Zhao native, and the piano room must have protected Zhao in its heart, so it was resolutely opposed to cutting Zhao. So he ignored the music room and turned to other ministers for advice. Others said: This is a good opportunity to attack Zhao. Fight more and fight less, and you will surely win a great victory. The prince decided to attack Zhao.
Before he left, Dr. Yan said to the prince, Zhao and I are old friends. We just gave a birthday present worth 500 gold. Now we are going to send troops to attack and attack, and we will certainly return in vain. ? Where does the prince like to listen? He ignored the canal, and in desperation, he grabbed the prince's belt and said, if you must send troops, please don't go in person. ? The prince couldn't stand the verbosity of the canal and kicked his leg. Shout canal:? I'm not thinking of myself, I'm thinking of your majesty. ? The prince turned and walked away.
Yan sent troops to attack Zhao, and Zhao was shocked. Zhao lost its elite in the previous war with China. At the critical moment, Zhao Haoqi Cheng Xiao finally had self-knowledge. He reused Lian Po, an old general who was dismissed in Changping Campaign, as a general, and led 80,000 new troops to face 400,000 Yan Jun in chestnut belly. At the same time, another general came to face the 200,000 Yan army with an army of 50,000.
Zhao's army is at a disadvantage. However, Lian Po and Lecheng defeated the Yan army in the Battle of Yan and the Battle of Dai respectively. They also killed Li Fu, the commander of the Yan army, and captured another enemy general. Le Jian, his son, took the opportunity to leave the Yan army and defected to Zhao. Now the prince is in a panic. He never dreamed that it would end like this. He led the beaten army to flee back to Yan. After the invasion of the Yan army, Lian Po pursued the 500-mile attack, entered the territory of Yan State and surrounded it.
As the saying goes, the thin camel is bigger than the horse, but Yan did not snatch success. Instead, Zhao Enemy at the Gates, the Prince of Yan was in a hurry to send someone to invite Lian Po. Lian Po said? It is ok to talk about peace, but you have to let Jiang Qu talk. ? Why the canal? Because there are only two people in Yan who oppose the felling of Zhao, one is Lejian, who has defected to Zhao, and the other is Jiangqu. The prince could not agree, so he appointed Jiang Qu as the prime minister, with full authority to negotiate with Zhao. Finally, Yan cut five cities and gave them to Zhao.
The cutting of Zhao by the prince of Yan can be said to be stealing chickens and costly rice, which also shows from one side that Zhao's military strength is indeed quite strong. Strangely, the history books downplay this battle, and the details of the war are unknown.
