Well the ancient Hellenes burned their dead and always after the battle even the defeted side was able to collect their dead to burn them it was a dishonour for them to leave their dead in battlefield with no proper burial...One good example is the campaing of Alexander the Great where the ashes of his dead soldiers returned back to their homes with all the honours for the family of the dead that died brave in combat ....And if you want more mythical-historical : the Troyan War ...
