Meng Tian was a famous general, and he was the most important general in the late Qin Shi Huang period, which can be described as a rising star, Qin Shi Huang let him lead this 300,000 army to build the Great Wall of The Xiongnu in the north. However, after Hu Hai became emperor of Qin II, Meng Tian was also killed.
After Meng Tian was killed, the 300,000 Qin army he led was handed over to the deputy general Wang Li.
At the end of the Qin Dynasty, Wang Li led these armies to quell the rebel army, and in the Zhao Kingdom he met Xiang Yu, and fought the Battle of Julu with Xiang Yu's Chu army, and Xiang Yu defeated Wang Li's elite Qin troops with fewer victories.
These armies, which were equal to Meng Tian, were all defeated or absorbed by Xiang Yu.
Wang Qi was mainly a general during the period when Qin Shi Huang unified the Six Kingdoms, and by the end of Qin, Wang Qi had already retired to the jianghu, to put it bluntly, he was already an old man, and he had no ability to lead troops at all.
In fact, he didn't know if he was alive or not.
As for how he died, it is not known when he died, because there is no record of it in the historical records. At the end of Qin, he should have been gone.
In addition to giving Meng Tian 300,000, Qin Shi Huang's army was 500,000 troops sent to Lingnan, and these people, under the leadership of Zhao Tuo at the end of Qin, declared independence and severed contact with the Central Plains.
Zhao Tuo was the later King of Nanyue!
Therefore, these half a million troops could not be counted on to come to the rescue. It is equivalent to 300,000 being wiped out by Xiang Yu, and 500,000 arriving in Lingnan and not listening to instructions.
Great Qin's main army was gone!
In fact, the army that can be used by the late Qin Dynasty II, the most courageous army to fight is still led by Zhang Handan, most of these people are prisoners who built the mausoleum of The First Emperor of Qin, and after Zhang Handan's training, he led these people to fight.
When dealing with the rebels of the Six Kingdoms, they have always been triumphant all the way, winning consecutive battles, even a fierce general like Xiang Liang, who was killed by Zhang Handan.
After Xiang Yu fought the Battle of the Giant Deer, Zhang Handan and Xiang Yu continued to fight, and neither of the two could take down the other, and the fight was equal.
In the end, Zhang Handan, fearing being framed by Zhao Gao, tended to negotiate peace with Xiang Yu, when his advisers told him that the second was controlled by Zhao Gao, and that no matter whether Zhang Handan won or lost the battle, he would eventually die.
Therefore, Zhang Handan had no idea of fighting, and he wanted to negotiate peace with Xiang Yu.
Xiang Yu's side wanted to defeat Zhang Handan to avenge his uncle Xiang Liang, but his strength did not allow it, plus he did not have much grain and grass.
In this case, Xiang Yu accepted it when he saw it was good, and he agreed to negotiate peace with Xiang Yu.
As for how Liu Bang entered Xianyang?
Because Xiang Yu and Liu Bang entered Xianyang in two ways, Xiang Yu dragged the main force of the Qin army, so the pressure on Liu Bang was reduced.
Liu Bang's march was also very difficult, fortunately, he encountered some rangers and scattered generals.
These people's combat effectiveness was not good, coupled with their disloyalty to Great Qin, seeing profit and forgetting righteousness, Zhang Liang bribed most of them with heavy money, and they easily arrived at Xianyang City.
After arriving in Xianyang, Zhao Gao and Qin II were already dead, Qin II was sent by Zhao Gao to kill, and Zhao Gao was killed by the Qin prince baby.
Zi Bao originally wanted to resist Liu Bang as the King of Qin, but he had no soldiers to use, that is, the commander of the light pole, and in the case of being forced to be helpless, he could only choose to surrender to Liu Bang.
It was equivalent to Zi Bao handing over the jade seal of the Qin state to Liu Bang and choosing to surrender to Liu Bang. Therefore, Liu Bang entered Xianyang City with such ease.
It can be said that the demise of Great Qin, Liu Bang and Xiang Yu are external causes, the most important thing in the great Qin Empire is Zhao Gao, he killed all those who were loyal to the Great Qin Empire, and let Qin II kill the brothers and sisters of Qin Shi Huang, which is equivalent to the Great Qin Empire being turned into an empty shell by Zhao Gao.
It was in this way that Liu Bang and Xiang Yu were given the opportunity to destroy Qin.
