Focused on winning his civil war, Atahualpa fatally misjudged the Spanish. He saw the small group as a potential asset—a source of mercenaries, horses, and superior swords to be captured and repurposed. He never considered them an existential threat to his empire, which sealed his fate.

The Spanish didn't defeat the Inca Empire at its height. They arrived after a smallpox epidemic killed the emperor and a subsequent brutal civil war between his sons shattered the empire. This left the civilization politically fractured and militarily exhausted, making it ripe for conquest by a small force.

Despite their aggressive plan, the psychological toll on the 168 Spaniards facing an army of thousands was immense. A firsthand account reveals their sheer terror, noting that many "urinate without noticing it out of pure terror" while waiting in hiding for the ambush to begin.

The absolute divine authority of the Sapa Inca meant that capturing a single man, Atahualpa, effectively paralyzed a 12-million-person empire. With no alternative power structure, his generals were bewildered and leaderless, allowing a tiny Spanish force to maintain control.

Communication during the pivotal meetings relied entirely on young, frightened interpreters who stumbled over their words. This created a dangerous filter of misunderstanding and potential misinformation, adding a layer of chaos and distrust to an already tense first-contact scenario.

In a surreal display of dominance, Francisco Pizarro held a formal dinner with Atahualpa just hours after slaughtering thousands of his followers. He then had a mattress prepared for the Inca emperor to sleep beside him, a bizarre and intimate assertion of absolute control.

The famous moment where Atahualpa supposedly threw down a prayer book, sparking the massacre, was a manufactured pretext. The Spanish, already in ambush positions, simply needed a justification. The book ending up in the dust—whether thrown or dropped—provided the trigger for their pre-planned attack.

To project absolute strength, Atahualpa engaged in psychological warfare against his own men. After he remained stoic as a Spanish horse breathed on him, he ordered the execution of soldiers (and their families) who had flinched, brutally enforcing a public code of fearlessness.

Atahualpa prioritized defeating his brother Huascar over addressing the existential threat of the Spanish. He viewed the conquistadors as a temporary factor to be managed, not a permanent invading force, a miscalculation that cost him his empire and his life.
