Based on some Herodotus I read about the persians/medes meeting the atheneans/hellenes at marathon.

Was it something that wasn't recorded? Or was it dishonorable or a sign of weakness?

I know there is mention of soldiers defecating themselves before or during battle, that phobos and pan ran amok, during the battle. But after?

The fighting at close quarters must have been utterly brutal, surely that left enough of a mark to record?

Maybe I am not reading the right things, any pointers or help would be useful.
