Wow. Utter disbelief. A foreign more technologically advanced people came in with weapons and technologies that were basically magic to these hunter gather/pastoral people. These people took up a last ditch desperate idea rather than submitting to the holocaust by the Voortrekkers of the Dutch. "The tribes of africa were largely barbaric and vicious" The incoming Dutch tribes were vastly more barbaric and vicious despite having had a 400 year head start and education and technology. Tag on to that the subsequent Anglo-Boer war which Boers still describe as their holocaust and you can't distinguish between any of these tribes. Humans are just a nasty evil species when they agglomerate.
