Enciso had been at a loss as to where to go, and Balboa convinced him to try Darien to the north. Once established there, Enciso had shown himself to be a weak man. How could Balboa not act? Enciso did not understand the Indians as Balboa did. He could see that the Indians were battle-hardened warriors. The Spaniards had not been there long enough to call these armies into existence. Balboa's strength had been to recognize this discord. He divided the great tribes, supported one against the other. His reputation spread. His muskets blasted away the faces of the greatest warriors. Balboa's soldiers spread smallpox and syphilis. His Spanish war dogs, great mastiffs and wolf hounds, tore children limb from limb. The blood from his great war machine made the rivers flow red and his name, Balboa, moved quickly, apace with these rivers of blood. Discord - (noun) disagreement or conflict
Balboa realizes that, on the battlefield, the Spaniards would be no match for the Indians.

Explain why recognizing the Indians’ discord benefits Balboa?
