Some one compares the military talent between Alexander and the Emperor of Qin. Errrr.....
In chinese history, emperors hardly directly battles. They usually accredit their generals to lead the army. So, it is not suitable to campare the military talent between Alexander and the Emperor.
If Alexander invade China, his adversary might be Bai Qi of Qin, surely not the emperor of Qin.
Bai Qi, some one called him God of War, but his other nickname is Human Butcher because of he killed 400000 prisoner. His has great military talent, but because of killing so many prisoner, history didnt give him an affirmative evaluate.
Sorry, my English is not so well, so i maybe made some foolish mistake. Pardon me, thanks.
Actually if Alexandra was to invade China, he will not be seeing Bai Qi. Alexandra was born in 356BC and died in 323BC. Bai Qi is born somewhere in the 200s BC and died in 257BC. As you can see, it was around 100years different. At the time of Alexandra, Qin is still not really very strong yet. If he was to enter China, he will most probably met resistance from the rest of the states first. And actually it is not really clear who will win and how.
It is worst off if you are talking about Xiang Yu or Liu Ban vs Alexandra the Great. These are not in the same era. And by the time of Xiang Yu and Liu Bang, many of the system had already been establish such as standardization, quality control, etc and so it really is not a very fair comparison.
If we insist on comparing the Xiang Yu with Alexandra the great, we would need to look into more details such as the troop training, number of troops, geographical and terrain on where they will fight, etc. Also we have to look at when the invasion will take place - before the fall of Qin empire or after the fall of Qin empire. If it was before the fall of Qin empire, then Alexandra would have to first destroy the Qin empire. There is two outcomes though,
Outcome 1:
Xiang Yu to aid Alexandra in destroying Qin Empire, so as to remove the dynasty. While at that Xiang Yu might use Alexandra to help destroy his mortal enemy and when Alexandra is fresh from battle and tire from the war, he will launch a surprise attack to destroy Alexandra and perhaps absorb his troop.
Outcome 2:
Xiang Yu will aid the king of Qin to defend against Alexandra the great. Then with the combined force of both Xiang Yu and Qin, Alexandra will stand no chance. However the battle will be long and casaulty will be incredible. This will no doubt benefit Liu Bang.
If Alexandra was to attack after the fall of Qin, which was also the start of Xiang Yu vs Liu Bang, then we will also be seeing 2 outcomes,
Outcome 1:
Xiang Yu and Liu Ban join force to fight against Alexandra the great.
Outcome 2:
Either Xiang Yu or Liu Ban will join force with Alexandra the great to battle the other force.
The final outcome will be undecisive but be sure that there will be a great many casualty on both side.
If Alexandra the Great was to attack China on any era, we have to actually look at the distance that his troop had to cross. And please be reminded that they do not have the same transport that we have now or the same transport that Mongol warriors have in Yuan Dynasty.
Thus crossing mountains to reach China would certainly weigh down on Alexandra's troop and they would have no rest... because the hardened veterans of the warring period will launch offensive on them immediately. Plus Alexandra the Great is the invasion party and they are not familiar with the terrain, weather and geography of China, which therefore will be a great disadvantage to them.
