The phalanx: the major invention of ‘civilized’ warfare
Raiding (dawn attack) by a Florida Indian tribe (de Bry, ± 1590)
Pitched battle type of intergroup agonistic behavior in primates generally, and possibly even in social and group territorial mammals generally (social carnivores, dolphins, etc.).
‘Lethal male raiding’ in the common ancestor of both humans and chimpanzees 6 8 mya (Wrangham’s synapomorphy or shared derived trait).
‘Lethal male raiding’ as independently evolved in both humans and chimpanzees (implied by van der Dennen)
THE (CHRONO)LOGICALLY POSSIBLE
THEORETICAL VIEWS ON THE EVOLUTION
OF WAR AS PITCHED BATTLE AND RAIDING
War in both humans (Hu) and chimpanzees
(Chi) as relatively recent ‘cultural inventions’
Hu Chi Bo
Differences between battle and raid
BATTLE RAID guerra (real war), combat / pitched battle fight/flight-like also known as motivationally guerrilla (little war) predation-like approx. balance of power very common in social carnivores and primates females and males
(much less so in humans) relatively uncommon among foraging peoples (if present often ritualized) precipitated by occurrence in animals confined to panids and hominids sex of the belligerents exclusively male occurrence in
'primitive' societies
Imbalance of power predominant and most lethal among foraging peoples
Differences between battle and raid
BATTLE RAID very common in contemporary warfare
(but less common in future) parallel lines / phalanxes clamor / bluff / intimidation display biomechanical principles impact of mass and speed, encirclement, feigned retreat psychology of the soldier (discipline) occurrence in modern warfare appearance characterized by explained by tactics underlying psychology relatively uncommon in contemporary warfare
(but more common in future) ambush / dawn attack / surprise raid stealth / secrecy tactical requirements (?) hit and run, torching, indiscriminate killing psychology of the warrior (frenzy)
Differences between battle and raid
BATTLE RAID too short line
(envelopment), too long line (penetration) chance encounter, failed raid, failed surprise attack ritualization (game-like war) possible reconciliation in principle possible divine ordeal, expiatory combat relatively low but may result in routing and massacre weakness and vulnerability conditioned by logistics, retreat surprise attack as default ritualization?
reconciliation?
no ritualization possible guerre à l'outrance no reconciliation, incessant cycles of retaliation and revenge raiding metaphysical aspects magicoreligious magnet lethality (casualties) relatively low but rapidly accumulating

War Causation: The Evidence
– The Correlates of War (COW) Project defines an
'international war' as a military conflict waged between national entities, at least one of which is a state, and that results in at least 1,000 battle-deaths of military personnel.
– War magnitude – the sum of all participating nations' separate months of active involvement in each war
– War duration – the length in months from the inception of the war to its termination
– War severity – total battle deaths of military personnel in each war
