Alexander was certainly pleased by the loyalty displayed by his soldiers.
"Thank you for your kind words. I'm glad all of you are well too," He replied.
And he was genuinely pleased.
He had half expected many of them to die facing such an overwhelming, and he certainly thought they would be pinned down by them for a long time.
This was because he had no real idea of the kind of damage heavy cavalry could do to light cavalry when the latter foolishly chose to face the attack head-on.
The way for light cavalry to win against heavy cavalry was to outrun and out-maneuver the much slower due to their heavy armor heavy cavalry and perform flanking attacks.
But since the enemy did not do such, the result was the total oblivion of their forces.
But even then, Alexander was surprised by the carnage he was able to wrought with even such a small number of men.
