>> 3,000–8,000 unarmed personal attendants/lightly armed guards [2]
Wikipedia said they had Knives and ropes
Almost all medieval battles end with routes and slaughter. What I am saying is 168 were able to take 5000 prisoners without the help of advanced technology?
How do you even know that? Text says they were armed with knives. And what do you mean "civilians" in this context? The article lists them as armed belligerents.
Well, I'm going by what the Wikipedia article says, that they were "Atahualpa's counselors, commanders, and unarmed attendants". According to the article the "armed host" was stationed outside the city and fled when the emperor was killed.
