Next Few Days (Part-1)
The cleanup following the surrendering of the army took a few days to complete, as Alexander's men worked hard to process these men- identifying and classifying them.
The officers and regular grunts were separated from each other as per the standard procedure, with the former being recognized by proofs such as a seal or badge or simply distinctive, more decorative armor.
This was done because the officers and various nobles were of higher status and thus deserved greater comfort as per the customs of the war of the time, while the regular grunts were asked to discard their weapons and lie down on the ground, then forced to spend a few nights outside the city under the clear open sky.
It was hence very fortunate for the men that it was the middle of summer and the nights actually cool and comfortable to sleep under.
