One step toward the accomplishment of this destiny, one advance toward the rearing of that great southern empire whose seat is eventually to be in Central America, and whose boundaries are to inclose the Gulf of Mexico, was the memorable expedition of William Walker to Nicaragua, invited there by one of its revolutionary chiefs.
The objects of that expedition, my dear C., were for a long time extensively misunderstood. They are now being apprehended by the northern people; they were long ago appreciated by the people of the South. It was to found, in a glorious land of promise, the institutions of the South, to extend them to other inviting countries of Spanish America, and, on the doubly-secured foundation of these institutions, and of military ideas of government, to build up the great tropical empire of America.
This great idea, I have reason to believe, was conceived in its fullness by WIlliam Walker. Regardless of the clamors of the world, he pursued, in reserve, though with a burning spirit, the single object to which he devoted fortune, life, and honor. And while that world was regarding his expedition as a short-sighted and rapacious conquest, a mere raid, a vulgar seizure of a nation's territory, he, in secret, had undertaken one of the grandest schemes ever set afoot in the western world.
Crushed may be all the aspirations of one individual. But the idea of empire conceived by an unfortunate leader can never die from the hearts of the South. Ever perpetuated and ever living, it will seek its accomplishment on and on, perseveringly and at the last irresistibly. This, dear C., is a serious truth; and the American people of all sections, of all countries, and of both continents, might as well accept the manifest destiny of a great, slave southern empire in the tropics of the western hemisphere.
