CHAPTER 32. The Mexican War

THE MEXICAN WAR

329. The Republic of Texas.--The Mexicans won their independence from Spain in 1821 and founded the Mexican Republic. Soon immigrants from the United States settled in the northeastern part of the new republic. This region was called Texas. The Mexican government gave these settlers large tracts of land, and for a time everything went on happily. Then war broke out between the Mexicans and the Texans. Led by Samuel Houston, a settler from Tennessee, the Texans won the battle of San Jacinto and captured General Santa Anna, the president of the Mexican Republic. The Texans then established the Republic of Texas (1836) and asked to be admitted to the Union as one of the United States.

330. The Southerners and Texas.--The application of Texas for admission to the Union came as a pleasant surprise to many Southerners. As a part of the Mexican Republic Texas had been free soil. But Texas was well suited to the needs of the cotton plant. If it were admitted to the Union, it would surely be a slave state or, perhaps, several slave states. The question of admitting Texas first came before Jackson. He saw that the admission of Texas would be strongly opposed in the North. So he put the whole matter to one side and would have nothing to do with it. Tyler acted very differently. Under his direction a treaty was made with Texas. This treaty provided for the admission of Texas to the Union. But the Senate refused to ratify the treaty. The matter, therefore, became the most important question in the presidential election of 1844.

331. Election of 1844.--President Tyler would have been glad of a second term. But neither of the great parties wanted him as a leader. The Democrats would have gladly nominated Van Buren had he not opposed the acquisition of Texas. Instead they nominated James K. Polk of Tennessee, an outspoken favorer of the admission of Texas. The Whigs nominated Henry Clay, who had no decided views on the Texas question. He said one thing one day, another thing another day. The result was that the opponents of slavery and of Texas formed a new party. They called it the Liberty party and nominated a candidate for President. The Liberty men did not gain many votes. But they gained enough votes to make Clay's election impossible and Polk was chosen President.

332. Acquisition of Texas, 1845.--Tyler now pressed the admission of Texas upon Congress. The two houses passed a joint resolution. This resolution provided for the admission of Texas, and for the formation from the territory included in Texas of four states, in addition to the state of Texas, and with the consent of that state. Before Texas was actually admitted Tyler had ceased to be President. But Polk carried out his policy, and on July 4, 1845, Texas became one of the United States.

333. Beginning of the Mexican War, 1846.--The Mexicans had never acknowledged the independence of Texas. They now protested against its admission to the United States. Disputes also arose as to the southern boundary of Texas. As no agreement could be reached on this point, President Polk ordered General Zachary Taylor to march to the Rio Grande and occupy the disputed territory. Taylor did as he was ordered, and the Mexicans attacked him. Polk reported these facts to Congress, and Congress authorized the President to push on the fighting on the ground that "war exists, and exists by the act of Mexico herself."

334. Taylor's Campaigns.--The Mexican War easily divides itself into three parts: (1) Taylor's forward movement across the Rio Grande; (2) Scott's campaign, which ended in the capture of the City of Mexico; and (3) the seizure of California. Taylor's object was to maintain the line of the Rio Grande, then to advance into Mexico and injure the Mexicans as much as possible. The battles of Palo Alto and Resaca de la Palma (May 8, 9, 1846) were fought before the actual declaration of war. These victories made Taylor master of the Rio Grande. In September he crossed the Rio Grande. So far all had gone well. But in the winter many of Taylor's soldiers were withdrawn to take part in Scott's campaign. This seemed to be the Mexicans' time. They attacked Taylor with four times as many men as he had in his army. This battle was fought at Buena Vista, February, 1847. Taylor beat back the Mexicans with terrible slaughter. This was the last battle of Taylor's campaign.

335. Scott's Invasion of Mexico.--The plan of Scott's campaign was that he should land at Vera Cruz, march to the city of Mexico,--two hundred miles away,--capture that city, and force the Mexicans to make peace. Everything fell out precisely as it was planned. With the help of the navy Scott captured Vera Cruz. He had only about one-quarter as many men as the Mexicans. But he overthrew them at Cerro Gordo, where the road to the City of Mexico crosses the coast mountains (April, 1847). With the greatest care and skill he pressed on and at length came within sight of the City of Mexico. The capital of the Mexican Republic stood in the midst of marshes, and could be reached only over narrow causeways which joined it to the solid land. August 20, 1847, Scott beat the Mexicans in three pitched battles, and on September 14 he entered the city with his army, now numbering only six thousand men fit for active service.

336. Seizure of California.--California was the name given to the Mexican possessions on the Pacific coast north of Mexico itself. There were now many American settlers there, especially at Monterey. Hearing of the outbreak of the Mexican War, they Set up a republic of their own. Their flag had a figure of a grizzly bear painted on it, and hence their republic is often spoken of as the Bear Republic. Commodore Stockton with a small fleet was on the Pacific coast. He and John C. Frémont assisted the Bear Republicans until soldiers under Colonel Kearney reached them from the United States by way of Santa Fé.

337. Treaty of Peace, 1848.--The direct cause of the Mexican War was Mexico's unwillingness to give up Texas without a struggle. But the Mexicans had treated many Americans very unjustly and owed them large sums of money. A treaty of peace was made in 1848. Mexico agreed to abandon her claims to Texas, California, New Mexico, Nevada, Utah, and Colorado. The United States agreed to withdraw its armies from Mexico, to pay Mexico fifteen million dollars, and to pay the claims of American citizens on Mexico. These claims proved to amount to three and one-half million dollars, In the end, therefore, the United States paid eighteen and one-half million dollars for this enormous and exceedingly valuable addition to its territory. When the time came to run the boundary line, the American and Mexican commissioners could not agree. So the United States paid ten million dollars more and received an additional strip of land between the Rio Grande and the Colorado rivers. This gave the United States its present southern boundary. This agreement was made in 1853 by James Gadsden for the United States, and the land bought is usually called the Gadsden Purchase.

338. The Oregon Question.--It was not only in the Southwest that boundaries were disputed; in the Northwest also there was a long controversy which was settled while Polk was President. Oregon was the name given to the whole region, between Spanish and Mexican California and the Russian Alaska. The United States and Great Britain each claimed to have the best right to Oregon. As they could not agree as to their claims, they decided to occupy the region jointly. As time went on American settlers and missionaries began to go over the mountains to Oregon. In 1847 seven thousand Americans were living in the Northwest.

339. The Oregon Treaty, 1846.--The matter was now taken up in earnest. "All Oregon or none," "Fifty-four forty or fight," became popular cries. The United States gave notice of the ending of the joint occupation. The British government suggested that Oregon should be divided between the two nations. In 1818 he boundary between the United States and British North America had been fixed as the forty-ninth parallel from the Lake of the Woods to the Rocky Mountains. It was now proposed to continue this line to the Pacific. The British government, however, insisted that the western end of the line should follow the channel between Vancouver's Island and the mainland so as to make that island entirely British. The Mexican War was now coming on. It would hardly do to have two wars at one time. So the United States gave way and a treaty was signed in 1846. Instead of "all Oregon," the United States received about one-half. But it was a splendid region and included not merely the present state of Oregon, but all the territory west of the Rocky Mountains between the forty-second and the forty-ninth parallels of latitude.
