The infantry retreat was too slow, essentially doomed to be eliminated systematically, but because of the high mobility of the cavalry, and the fact that Turkic cavalry each had more than three horses, they were able to break through in a dispersed manner and then gradually regroup.
Yet the problem was, if the enemy had set an ambush, how could they not think of this possibility?
It was likely not only around Chang'an where the ambush had been set.
Along the way back to the steppes from Chang'an, at every pass and every city, it seemed the Liang Army awaited.
Even if they could break out of the encirclement here once, reaching the steppes was far and uncertain...
As the saying goes, defeat is as rapid as a collapsing mountain; once the order to retreat was issued, the Turkic soldiers would surely be in a state of panic, and the chieftains of each tribe would harbor their own deceitful intentions…
Once that occurred, the situation would become completely unmanageable.
