The Battle of Changping is a very classic battle in the historical record, in this war, it is mainly about four famous generals, including Lian Po and Zhao Kuo of the Zhao State, and Wang Gong and Bai Qi of the Qin State. The reason why the two countries broke out the Battle of Changping was mainly because before the Changping War, the Qin state and The Republic of Korea had a three-year battle, in which the Qin state used 100,000 troops to kill more than 50,000 Korean troops, and there were more than ten cities and pools captured, but the most important thing for the Qin state was the Shangdang County in South Korea, and when Korea was attacked by the Qin state and had no way to retreat, it transferred the Shangdang County to the Zhao state.
Shangdang County can be said to be a hot potato, and someone once persuaded Zhao Wangdan to tell him that Shangdang County was the heart meat for the Qin State, and it was determined to win, if he took over this hot potato, then it was likely to be attacked by the Qin State. However, for the king of a country, it was his life's duty to expand the territory, and how could such a fertile piece of land be willing to be discarded in front of him, so in the end Zhao Wang Dan still took over shangdang county. Sure enough, after Zhao Guo took over Shangdang County, Qin Sent the famous general Wang Gong to attack Shangdang County, and the famous general Lian Po who was stationed in Shangdang County at that time was also a famous general of zhao. Regarding Lian Po, he is recorded in the story "General Xiangru", which describes that the reason why the Qin State has not dared to attack the Zhao State is mainly because of the existence of Lin Xiangru and Lian Po in the Zhao State.
Wang Gong spent two months attacking Shangdang County, and Lian Po could only retreat all the way to the south, but the Qin army did not spare the Zhao army to the narrow valley, and at this time the Zhao army was completely unable to move, and was in a state of inability to advance or retreat. Since then, Lian Po has always adopted the combat strategy of avoiding war, and there must be a reason why the great generals avoided fighting, because at that time, the strength of the Zhao army had been crushed by the Qin army, and the grain supply had been cut off, and the army was not only severely damaged but also had insufficient food supplies, and there was only one dead end in a hard attack. At this time, Zhao Wangdan sent emissaries to various countries to borrow grain after receiving the news from the front, but no country was willing to borrow it, mainly because all countries had already learned about the state of Zhao Guo at this time, and even if they borrowed grain, there was no room for reversal.
Lian Po, who had always avoided fighting, made Zhao Wang Dan very anxious, and Zhao Wang Dan then sent Zhao Kuo to take over Lian Po's position as the commander. Zhao Kuo has a very famous idiom in history that is specifically used to describe him, that is, "talking on paper", because this incident made him and stupid people draw an equal sign. In fact, Zhao Kuo is not not outstanding, he can also be regarded as a small genius. At this time, not only did Zhao Guo change the main general, but Qin Guo also replaced Wang Gong with a deputy commander, letting Bai Qi take over the position of commander. However, Zhao Kuo's arrival could not save the state of the Zhao army at that time, and then Zhao Kuo learned of Bai Qi's arrival and chose to attack the Qin army in the form of suicide. In the end, a 30-year-old general died on the battlefield, and Bai Qi became famous for the Changping War.
