Battle of Cajamarca

The Battle of Cajamarca was the ambush and capture of the Inca ruler Atahualpa by Francisco Pizarro and a small Spanish force on November 16, 1532. The "battle" involved the massacre of thousands of Atahualpa's unarmed entourage of nobles and attendants, in the great plaza of Cajamarca. The seizure of Atahualpa marked the opening stage of the conquest of the pre-Columbian Inca civilisation of Peru.
