The Greatest Decisive Battle In Whole History

Metaurus because if Hasdrubal had won, the whole war may have been won againest the Romans and they would never have gained the dominance they did.

First of all the Arab army outnumbered the Chinese army not by more than 3 to 1, but by 20 to 1. Only 10,000 Tang troops were involved in the actual battle compared to the Arab side of more than 200,000. Tang also had 20,000 mercenaries who switched sides in the middle of the battle. So if you add 20,000 to the 200,000 that makes 22,0000 versus 10,000 which is not 3 against 1 but 22 against 1. How could it possibly have any ramification for the future, if you know anything about Tang history, every skirmish it ever fought involves more than 10000. Now Tang has more than 50,0000 battle hardened troops. I'm sure it could easily crush the whole Arab nation it were wanted to- but it had other things to contend with- the An Lushan rebellion. How could the An Lushan rebellion be related to a border skirmish? First compare the magnitude of each. The An Lushan rebellion involves the whole China and lasts for 8 whole year, killing two third of China's population(30 million). The economy of Tang China was almost nonexistant after the rebellion so is the unity of the empire; independent jiedushi took control of local area as well as military power. The central government had no military after that. What you are saying if that a pirate raid( 2 killed) on a coast of Alabama caused the American Civil War(0.5 million killed).
