We do not have to imagine how prehistoric warfare might have been fought. We can see for ourselves how prehistoric warfare was fought and even to this very day is fought now. Not so much warfare as a modern would understand the term but rather ritual combat.
The highlanders of New Guinea a battle as having been filmed [circa 1961 and edited as presented] and made available for your perusal.
Read further thanks to You tube remarks about the film:
"'Dead Birds'. Robert Gardner, 1964 . . . Dead Birds is a film about the Dani, a people dwelling in the Grand Valley of the Baliem high in the mountains of West Papua. When I [Robert] shot the film in 1961, the Dani had a classic Neolithic culture. They were exceptional in the way they dedicated themselves to an elaborate system of ritual warfare. Neighboring groups, separated by uncultivated strips of no man’s land, engaged in frequent battles. When a warrior was killed in battle or died from a wound and even when a woman or a child lost their life in an enemy raid, the victors celebrated and the victims mourned. Because each death needed to be avenged, the balance was continually adjusted by taking life. There was no thought of wars ever ending, unless it rained or became dark. Wars were the best way they knew to keep a terrible harmony in a life that would be, without them, much drearier and unimaginable."
Warfare of this type occurring normally as a result of: 1. Inter-tribal blood feud. 2. Bride-snatching. 3. Inter-tribal raids.
Lots of foot-stomping, making faces, ribald and obscene jokes, taunts, insults. Combatants not closing on the adversary, exchanging arrows at a prodigious rate.
THE GOAL MORE THAN ANYTHING ELSE IS TO SAVE FACE, REVENGE SOME INSULT, SHOW YOUR MANLINESS AND GRIT, ATTAIN HONOR WITH A WOUND! NOT TO OBLITERATE YOUR OPPONENT, KILL AND DESTROY IN A GRATUITOUS MANNER!
Men as wearing a penis sheath from what I can discern the length of the sheath designating some sort of rank. The higher your rank the longer your penis sheath.
Go watch it all.
