Atahualpa (Conquest of Peru).

Fought 1531, between 160 Spaniards under Pizarro, and 30,000 Peruvians, forming the escort of the Inca, Manco-Capac. The battle was nothing but a butchery, Pizarro, who had invited the Inca to visit him, falling upon the unsuspecting Peruvians, seizing Manco-Capac, and slaughtering 4,000 men, without the loss of a single Spaniard.
