Now, Atahualpa, when he sees these guys arrive, he obviously needs to recalibrate because clearly there are a lot more Spaniards out there.

And he can tell they're not just going to go away when they've got the gold.

This is not just a raid.

This looks more like an invasion.

And at this point, Atahualpa says to Pizarro, are you going home or are you going to stay?

I mean, it's been great having you, but, you know.

When are you leaving?

Shall I check out the train times?

And for the first time, Pizarro says to him, we are going to stay and we are going to divide up your workers, your people, among ourselves.

And this is a huge shock for Atahualpa.

Pizarro says, don't worry.

We will leave the northern bit, the province of Quito, to you.

That's your heartland.

It'll be your kingdom.

But Atahualpa, for the first time, thinks...

I don't believe these guys.

They are not going to honour this agreement.

Exactly, exactly.

Now, all the time, the gold has been rolling in, as you said.

And at the first week of May 1533, Pizarro orders his men to start melting it down.
