On November 15th 1532, 168 Spanish conquistadors arrive in the holy city of Cajamarca, at the heart of the Inca Empire, in Peru. They are exhausted, outnumbered and terrified – ahead of them are camped 80,000 Inca troops and the entourage of the Emperor himself. Yet, within just 24 hours, more than 7,000 Inca warriors lie slaughtered; the Emperor languishes in chains; and the victorious Europeans begin a reign of colonial terror which will sweep through the entire American continent.
