After the battle of Puná the Spaniards were greatly annoyed by the enemy, who kept up a desultory and harassing warfare, and they welcomed with joy the arrival of a strong reinforcement under Hernando de Soto, the future discoverer of the Mississippi. With a hundred fresh men and a supply of horses for the cavalry, Pizarro did not hesitate to cross to the mainland. The inhabitants, although previously on the most friendly terms with the Spaniards, opposed their landing, but with no great energy; and a charge of horse drove them to the woods. At Tumbez, however, a grievous disappointment awaited the invaders. With the exception of half-a-dozen of the principal buildings, the city was razed to the ground; and of the rich spoils the Spaniards had reckoned upon, not a trace was left. The adventurers were greatly discouraged by this discovery. “The gold of Peru seemed only like a deceitful phantom, which, after beckoning them on through toil and danger, vanished the moment they attempted to grasp it.” They lost heart in this search after an intangible treasure; and Pizarro, fearing disaffection as a consequence of inaction, hurried them into the interior of the country. At thirty leagues from Tumbez, he founded, in conformity with his vow, the city of San Miguel; and, after waiting several weeks for further reinforcements and receiving none, he left fifty men for the protection of the new settlement, and marched with the remainder in search of the Inca, proclaiming every where, as he proceeded, the religion of Christ, the supremacy of the Pope, and the sovereignty of Charles the Fifth.
