In the opening years of our national life the Western backwoodsman found the Spanish ownership of the mouth of the Mississippi even more hurtful and irksome than the retention by the British king of the posts on the Great Lakes. After years of tedious public negotiations, under and through which ran a dark woof of private intrigue, the sinewy western hands so loosened the Spanish grip that in despair Spain surrendered to France the mouth of the river and the vast territories stretching thence into the dim Northwest. She hoped thereby to establish a strong barrier between her remaining provinces and her most dreaded foe. But France in her turn grew to understand that America's position as regards Louisiana, thanks to the steady westward movement of the backwoodsman, was such as to render it on the one hand certain that the retention of the province by France would mean an armed clash with the United States, and on the other hand no less certain that in the long run such a conflict would result to France's disadvantage. Louisiana thus passed from the hands of Spain, after a brief interval, into those of the young Republic. There remained to Spain, Mexico and Florida; and forthwith the pressure of the stark forest riflemen began to be felt on the outskirts of these two provinces. Florida was the first to fall. After a portion of it had been forcibly annexed, after Andrew Jackson had marched at will through part of the remainder, and after the increasing difficulty of repressing the American filibustering efforts had shown the imminence of some serious catastrophe, Spain ceded the peninsula to the United States. Texas, New Mexico, and California did not fall into American hands until they had passed from the Spaniard to his half-Indian sons. Many decades went by after Spain had lost her foothold on the American continent, and she still held her West Indian empire. She misgoverned the islands as she had misgoverned the continent; and in the islands, as once upon the continent, her own children became her deadliest foes. But generation succeeded generation, and the prophecies of those far-seeing statesmen who foretold that she would lose to the northern Republic her West Indian possessions remained unfulfilled. At last, at the close of one of the bloodiest and most brutal wars that even Spain ever waged with her own colonists, the United States intervened, and in a brief summer campaign destroyed the last vestiges of the mediaeval Spanish domain in the tropic seas alike of the West and the remote East.
