The first entrance of Spanish Christianity upon the soil of the United States was wholly characteristic. In quest of the Fountain of Youth, Ponce de Leon sailed for the coast of Florida equipped with forces both for the carnal and for the spiritual warfare. Besides his colonists and his men-at-arms, he brought his secular priests as chaplains and his monks as missionaries; and his instructions from the crown required him to summon the natives, as in the famous "Requerimiento," to submit themselves to the Catholic faith and to the king of Spain, under threat of the sword and slavery. The invaders found a different temper in the natives from what was encountered in Mexico and Peru, where the populations were miserably subjugated, or in the islands, where they were first enslaved and presently completely exterminated. The insolent invasion was met, as it deserved, by effective volleys of arrows, and its chivalrous leader was driven back to Cuba, to die there of his wounds. It is needless to recount the successive failures of Spanish civilization and Christianity to get foothold on the domain now included in the United States. Not until more than forty years after the attempt of Ponce de Leon did the expedition of the ferocious Menendez effect a permanent establishment on the coast of Florida. In September, 1565, the foundations of the oldest city in the United States, St. Augustine, were laid with solemn religious rites by the toil of the first negro slaves; and the event was signalized by one of the most horrible massacres in recorded history, the cold-blooded and perfidious extermination, almost to the last man, woman, and child, of a colony of French Protestants that had been planted a few months before at the mouth of the St. John's River.
