The aftermath of a battle

[Centurio Nixalsverdrus]

Dear EB historians,

having regarded "the aftermath of battle" by Nate among the EB loading screens, I came to think of what was the aftermath like in EB timeframe? Were the victors running over the battlefield killing the wounded enemies, depriving them of their properties? Did anybody take care of the wounded? How was that organized, I have heard that the Romans for example had doctors with the legions, what about other factions? I'd like to know because in the game we never actually take care of the wounded of course, the battle ends when the enemy is dead.
