THE MEXICAN WAR
In America the Mexican War, vast in its territorial results, still more so in its effect upon society, broke out in 1846 over the admission of Texas to the United States. The superior fighting strength of the more northern race was at once made evident. Small bodies of United States troops repeatedly defeated far larger numbers of the Mexican militia. The entire northern half of Mexico was soon occupied by the enemy. Expeditions, half of conquest, half of exploration, seized New Mexico, California, and all the vast region which now composes the southwestern quarter of the United States. [Footnote: See The Acquisition of California.]
Farther south, however, the more populous region wherein lay the chief Mexican cities remained resolute in its defiance; and the Washington Government despatched against it that truly marvellous expedition under General Scott. The heroisms and the triumphs of Scott's spectacular campaign deserve to be sung in epic form. The dubious justice of the war was forgotten in its overwhelming success. From the captured Mexican capital the conquerors dictated such peace terms as added to the United States almost half the territory of her helpless neighbor. Europe at last awoke to the fact that there was but one Power on the American continent, a power with which even the mightiest monarch could ill afford to quarrel. [Footnote: See The Mexican War.] The very year in which the final treaty of peace was signed (1848) the Mormons, a religious sect, finding themselves unwelcome and out of place in Illinois, moved westward in a body. Enduring every hardship, every privation, perishing by hundreds in the trackless deserts, captured and put to torture by the Indians, they still persevered in their migration, and, halting at last in the valleys of Utah, began the settlement of the Central West. [Footnote: See Migrations of the Mormons.]
Also in that same year, gold was discovered in California. Thousands of eager adventurers flocked thither, and thus the vast wilderness that Mexico had lightly surrendered had hardly become United States territory ere it was filled with people, not listless semi-savages, but eager, energetic men, resolute and resourceful. The West joined the march of progress; it doubled the wealth and prowess of the East. [Footnote: See Discovery of Gold in California.]
