During the reign of King Qin Zhao, there was a high-profile general named Bai Qi, who was an outstanding military general who captured five cities and made great achievements. He loved to lead thousands of troops and horses into battle, so much so that the soldiers of Chu, Wei, and Zhao were afraid when they heard his name. In the 260th year of King Zhao, the Qin State attacked Korea, and the people of Shangdang fled to the Zhao State one after another. The Qin State seized the opportunity to attack the Zhao State, but the Zhao State relied on the high walls to hold on, refusing to face the battle, and tried to drag down the Qin army through a protracted war. After the Qin army used a counter-strategy, Zhao Kuo of Zhao State fought with Bai Qi. Under the front and rear attacks, the Zhao army was divided and surrounded, and the siege lasted for more than a month, resulting in the Zhao army running out of food and killing each other, and finally became prisoners, this battle is the famous Battle of Changping.
Subsequently, the state of Qin sent troops to attack Handan again, but Bai Qi objected and said that he would not personally take command of the expedition. In desperation, the king of Qin sent other generals to lead the army, but suffered a crushing defeat. Bai Qi said at this time: "If I had followed my advice and not attacked Handan, there would have been no such failure. When the King of Qin heard this, he was furious and sent Bai Qi out again. Bai Qi claimed that he was sick and could not go into battle, and in anger, the king of Qin belittled him as a common man.
Soon after, Bai Qi was about to leave, but met the traitor Fan Sui on the road. Fan Sui suggested to the King of Qin that if this was the case, it would be better to execute Bai Qi, so King Zhao sent someone with a sword and ordered Bai Qi to kill himself. Bai Qi said his last words on his deathbed: "I regret why I didn't kill those 400,000 soldiers in the first place." And just like that, with remorse, he made it through his last moments.
