First of all, we don't consider historical exaggeration. In Records of the Historian Biography of Tian Lei's Wang Jian, it is recorded that "there were more than fifteen people in Qin who worshipped Zhao because of Changping", and it was also recorded that after the battle of Changping, young and middle-aged people were almost lost. Therefore, the figures of Qin 600,000 and Zhao 450,000 are basically true and may be slightly exaggerated.

It's just that I estimate that the number of troops on both sides should not be all combatants, but should include logistics forces. Considering where the war was, it was also a stalemate for three years, and it was in the upper party and the richest place in Zhao, so Zhao adopted transportation and subsistence agriculture, which should basically meet the needs of the army.

And Qin should be the force of the whole country to fight this battle), "Lv Chunqiu Yan Ying" has "Qin is defeated for three years, and the sergeant is exhausted and eats" (the word □ is short of "food"), so the basic estimate may be a large part of 600,000, and more than half may be transport troops and logistics troops responsible for farming. This may explain the problem of logistics supply.

There's also the question of pit killing. First of all, it can be said that the number of people who have been killed is definitely exaggerated. At that time, Zhao mobilized a water army of up to 450,000 people. After the fierce fighting, it is unlikely that there will be 400,000 left. Moreover, considering that the world was undecided at that time and Qin was the target of public criticism, it was only after such a fierce battle. Although we won, we lost more than half, and it takes time to recover our national strength and military strength. The surrendered Zhao army could not support it, and it was impossible to take it back. Therefore, on the one hand, it completely weakened Zhao, on the other hand, it also killed other countries, which made them need to consider more when launching the war against Qin. So it is very likely that the number has been greatly exaggerated, and it may only kill 65438+ tens of thousands to 200,000 troops.

Therefore, it is understandable that 300,000 people left and10-200,000 Zhao Jun was killed.

And according to the latest research, the location of the pit killing is very scattered, not concentrated in one pit at a time, but scattered, so Tian Lei may be separated from the dead soldiers many times, probably because he was asked to dig a pit or drink wine, so it is understandable to carry weapons.

The above is my opinion, for reference only.
