My knowledge about Pizarro and the Incas is zero so take this for what it’s worth. My impression is that the image of a handful of Spaniards winning fights with vastly superior numbers of natives who were scared shitless because of the firearms, horses and local superstitions is quite wrong.
I can imagine Pizarro addressing his men saying “Ok, gang, here’s the plan for tomorrow: all 200 of us are going to fight 200,000 indians and win a great victory”.
I can see the men replying:
#1- Hey, Pizarro, are you sure this is a good idea?
#2- Yeah, can’t we put it off until next week so I can finish the report I’m working on?
#3- I think I hear my mother calling me… gotta go… email me if you need anything…
I think a much more accurate picture is that the Spaniards took advantage of local disputes and wars among tribes. They would land somewhere and ask the local chief “Hi Chief, how are things going? Everything OK?” And the chief would say: “Well, we’re doing ok but this would be a much nicer neighborhood if it weren’t for the guys over those hills there who come down here once in a while and take our women, our cash and then kill a few of us for good measure”.
The Spaniards would then convince them that they would become allies and would be invincible and beat the crap out of the guys on the other side. In the actual fighting the Spaniards would be a very small minority and it was mostly natives on both sides. The Spaniards were mostly valuable as leaders and catalists, not because the were any better at fighting. Most Spaniards did not have firearms or horses. Mostly what they had was a crazy sense of destiny where conquering the world was possible (sort of like Bill Gates).
Also, the imposition of Spanish jurisdiction was not an overnight thing:
-Pizarro: You have lost in battle Chief. Sign here your surrender
-Chief: It is a sad day for my people but I sign to avoid further bloodshed. (signs and sighs)
-Pizarro: Ok, now all your base belong to us.
Effective Spanish control, jurisdiction and customs probably took many decades, even centuries to introduce, and in many places never were. The Spanish managed to become the rulers because they managed to sustain a certain peace among the tribes. However little the natives might have liked the Spanish, in many cases they were not affected so much by them and in any case it was better than fighting the tribe next door every Monday, Wednesday and Friday.
In a nutshell: I think a small number of Spaniards beating the crap out of large numbers of Indians is probably all wrong. But then again, did I say I have never read the history of Pizarro and the conquest of Peru? Which is a shame because I have right here Prescott’s History of the Conquest of Peru which I have been intending to read for a while now… maybe one of these days…
