Roman emperors didn't flee from battle. is one way to read this.

Hell yeah Persian empire! Let's fucking goooooooo!!!!!!!!!!!

why is that a sad thing?

Did Persian kings actually fight at the front line? Far as I know they just paid tons of mercenaries while sitting somewhere far away.

Besides, Persians shouldn't talk shit in Muslim hearing range. Considering how utterly Persia was demolished by them, you'd think their people collectively forgot how to hold a sword.

You can't die in battle if you never go to the battle...
