The Mexican-American War (1846-48) was fought over control of Texas. Mexico lost all the battles and in the peace treaty gave up northern territories in exchange for $15 million.

Causes

The basic cause of the war from the Mexican side was the refusal to recognize the independence of Texas, which successfully revolted in 1836. In ten years as an independent republican Texas was recognized by the major nation's of the world, but not by Mexico. Mexican politicians promised that if the U.S. ever annexed Texas it would mean war. Annexation took place in 1845 and war promptly followed.

From the American side, the goal of "Manifest Destiny" especially appealed to Democrats; Whigs strenuously opposed the idea. The election of 1844 of President James K. Polk, a Democrat who believed in expansion, set in train the annexation and an offer to purchase California, which Mexico rejected.

From the borderland perspective, Mexico had forfeited its control. It withdrew most army units to engage in civil wars for political power, leaving the border region defenseless against repeated large-scale Indian raids. The Hispanics in Texas ("tejanos"] and New Mexico ("nuevomexicanos") were affiliating more with the U.S. in terms of economy and security, and welcomed the American takeover.

Perceptions of each side

Inside the U.S.

Along the border

Delay (2007) and Reséndez (2004) explain the American need to suppress Indian raids originating from Mexican territory. During the 1830s and 1840s, northern Mexico experienced a terrifying increase in interethnic violence as Comanches, Kiowas, Apaches, and other Indians attacked Mexican settlements across nine states in northern Mexico. Raids claimed thousands of lives, ruined the ranching and mining industries, and forced most Hispanics to flee the border region. Just as importantly, the violence shaped how Americans and Mexicans came to view each other in advance of the war. US observers saw Indians driving Mexicans backward, with the government there uninterested and incapable of defending the territory it had seized from Spain. With the Mexican army being used primarily to wage political battles for control of the government, Hispanic residents of the affected areas despaired that their government would help them; they increasingly welcomed American intervention, which they correctly expected would end the Indian raids. Mexican politicians complained Washington was fomenting Indian raids in order to acquire territory.

Meanwhile in New Mexico, the economy and society were becoming integrated with the U.S. and nuevomexicanos were increasingly estranged from Mexico. Some Catholic priests tried to prevent full integration by restricting marriages between Protestant American men and Mexican Catholic women. By 1846 little fervor existed in New Mexico for resisting the American army. Consequently the Mexican army did not attempt to defend New Mexico or California. Few Hispanics after the war went to Mexico, as the great majority of tejanos, californios and nuevomexicanos preferred American rule..[1]

In Mexico

In Mexico itself Henderson (2007) emphasizes that Mexican agency in going to war reflected a profound sense of weakness. Mexico's revolutionary experience had produced a virulent factionalism based on divisions of race, class, region and ideology. The successful by Texas in 1836 only made it more clear that Mexico was too weak to populate, control and defend its northern territories, but that opinion was derided by Mexican politicians. Instead, they all denounced the policies of their rivals. The only common denominator was that Texas must be reconquered, even if that meant war with overwhelmingly superior U.S. military and economic power.

In any case Mexico was in no position to negotiate with the U.S. because of its instability. In 1846 alone the presidency changed hands 4 times, the war minister changed 6 times, the finance minister changed 16 times. [2] As one Mexican historian explains: [3]

"Mexican public opinion and all the various political factions that aspired to or that actually shared in power at that time, had to—willingly or unwillingly—participate in a very hawkish attitude toward the war. Anyone who tried to avoid open conflict with the United States was treated as a traitor. That was precisely the case of President José Joaquin de Herrera. At one time he, at least, seriously considered receiving the American special envoy, John Slidell, in order to negotiate the problem of Texas annexation peacefully. But as soon as he assumed that position, the president was accused of favoring the handing over of a part of national territory; he was accused of treason and was overthrown."

Mexico was not a democratic country. The Mexican people as a whole remained largely indifferent—otherwise Winfield Scott's landing at Vera Cruz and his decisive march on Mexico City would have been impossible. Mexico, unable to pursue a pragmatic strategy of negotiation and compromise, suffered—and celebrated—a "glorious defeat" that further unraveled a disunited nation.

Start of war

Shortly after the U.S. Congress by joint resolution annexed Texas in 1845, the Mexican government recalled its minister from Washington and broke off diplomatic relations. Government newspapers in Mexico City acted as if war already existed. On June 15, 1845, Brevet Brigadier General Zachary Taylor, commanding American troops in the southwest, received orders to move forward into some disputed territory "on or near the Rio Grande." In August he encamped on the west bank of the Nueces River, Texas. President Polk then sent John Slidell of New Orleans to Mexico City with a proposal to adjust the boundary dispute, and to purchase Upper California and New Mexico. Mexico rejected Slidell's mission, and rejected efforts by Britain to broker a compromise. It was time for war.


When the Mexican government refused to negotiate with Slidell, Polk on Jan. 3, 1846, instructed Taylor to advance. Within a month Taylor's forces were at the Rio Grande. On April 12 General Pedro Ampudia demanded that Taylor retreat beyond the Nueces. Taylor held his position, and on April 24 a Mexican force ambushed a party of American dragoons on the Texas side of the Rio Grande. Polk already had decided to recommend a declaration of war. On May 11 his message went to Congress. A war appropriation bill providing for enlistments passed both houses by overwhelming margins. Its preamble declared that the war existed by the act of Mexico.

Military operations 1846

New Mexico

The American strategy called for the occupation of New Mexico and California, a blockade of the Mexican coasts, and a principal thrust toward Mexico City. On Aug. 18, 1846, General Stephen W. Kearny, after an 850-mile (1,370-km) overland advance, occupied Santa Fe, New Mexico, with a force of 1,700 men.

California

Kearny continued on to California at the head of his cavalry, and fought a small engagement at San Pascual on December 6, 1846, before reaching San Diego. The U.S. Navy commanded first by Commodore John D. Sloat then by Commodore R. F. Stockton, played the major role in the conquest of California, aided by colonel John C. Frémont and his 60-man army detatchment which entered from the north and took control of Sonoma and Monterrey.


Military operations 1847

After General John E. Wool failed to take Chihuahua, Colonel A. W. Doniphan with 850 men entered the city on March 1, 1847. During the early phases of the war, the most important fighting was in northeastern Mexico. After the battles of Palo Alto on May 8, 1846, and Resaca de la Palma on May 9, Taylor's army followed the retreating Mexicans across the Rio Grande, occupied Matamoros, and advanced to Monterrey, capital of Nuevo León province, which fell after siege and assault, September 21-23, 1846. Large elements of Taylor's army were shifted to Scott's command form an invasion force.

Battle of Buena Vista

In February 1847, near the small outpost of Buena Vista, Taylor and his 4,800 regulars faced an army of about 15,000 Mexican soldiers led by General Santa Anna. What might have been a rout ended up in an American victory, with the American troops maneuvering quickly and regrouping in order to keep the surrounding Mexican troops from completely overrunning their position. large. On February 20, Taylor occupied an exposed position at Agua Nueva. When he learned that Santa Anna was approaching, Taylor retreated along a road 12 miles (19 km) toward Saltillo. Halting near the northern end of a mountain pass at the hacienda of Buena Vista, Taylor enfiladed with artillery the deep gullies that creased most of the pass. When skirmishing began on February 22, it became apparent that Taylor lacked sufficient strength on the American left, where the Mexicans were able to approach along the shallow end of lateral ravines and on the slopes of the adjoining mountains. The next morning the Mexican thrust pushed back the American left flank. As Santa Anna's troops poured through to the hacienda, Taylor threw in his reserves and with the invaluable aid of Jefferson Davis's Mississippi Rifles regiment, checked the retreat. Artillery batteries of Braxton Bragg, J. M. Washington, and Thomas W. Sherman cut down further Mexican attacks. Taylor then reorganized his line toward the east, and by nightfall had recovered the lost ground. During the night the Mexican army began its retreat. The American losses were 746; reported Mexican losses (including prisoners and deserters) were 3,494. Buena Vista was the most important battle of the war, for Santa Anna was forced to withdraw, leaving Mexican forces demoralized, and politicians more willing to negotiate.

Battle of Buena Vista 1847

Invasion

Polk then ordered a seaborne expedition to Veracruz, and an inland march from that port to Mexico City. This policy gave effective leadership in the war to General Winfield Scott. It drew some troops from Taylor's command. On Mar. 9, 1847, Scott's army landed practically unopposed near Veracruz, and after a brief siege captured the city on March 29.

Cerro Gordo

The Americans then turned toward Mexico City, and at Cerro Gordo, April 17-18, 1847, faced another army under Santa Anna. The battle was fought along the route of the Mexican national highway, at a narrow defile in rugged foothills 50 miles (80 km) northwest of Veracruz. Scott invading army numbered 8,500 and Santa Anna's Mexican defenders numbered 12,000. Fearful of the yellow fever season after the capture of Veracruz, Scott hurried his men toward the highlands and Mexico City. Santa Anna prepared defenses at a pass just below Cerro Gordo. At the suggestion of Captain Robert E. Lee, Brigadier General David E. Twiggs's division left the highway some distance from the Mexican position and struck out in a flanking movement over rough terrain. On April 17, Twiggs's men occupied one defended height, and the next day Colonel W. S. Harney's command stormed the main defensive bastion. Simultaneously, Brigadier General James Shield's brigade struck hard against the extreme left flank of the Mexican army as it fled down narrow paths into the canyon of Río del Plan. The Mexicans lost 1,200 men and the Americans 431. This was Scott's last major battle before he reached the Valley of Mexico.

Chapultepec

Santa Anna refused to negotiate so Scott invaded the Valley of Mexico. There he won the important battles of Contreras and Churubusco, August 19-20, 1847. When another armistice failed to bring peace, Scott's men won the bloody battle of Molino del Rey on September 8, and reached Mexican positions on Chapultepec Hill, September 12, which were the key to the inner defenses of Mexico City. Contrary to the advice of his best engineers, Scott decided to enter Mexico City by causeways leading to its western gates. This course required taking Chapultepec Hill, 200 feet (60 meters) high. In addition to natural defenses it had for protection an array of high walls, ditches, and parapets. On its crest a garrison held a group of military college buildings, and at the approaches Santa Ana placed troops which were about equal in number to the 7,180 Scott employed in the operations. On September 12, American artillery opened fire on the fort. The next morning, Scott sent Brigadier General John A. Quitman's division, with a select storming party from Twiggs's division, against the south and east walls of the Chapultepec enclosure. Simultaneously, Brigadier General Gideon J. Pillow's division fought its way forward from the west. Finally the attackers reached the western walls, hoisted scaling ladders, and in a desperate hand-to-hand encounter fought their way to the upper ramparts on the top of the hill. Thereupon the garrison's commander surrendered the site that had once been the residence of the Spanish viceroys, and Mexico City lay open. In the fighting Santa Ana lost about 1,800 men, including those missing; estimated American losses were 450. The city surrendered on September 14. Santa Anna escaped, and soon resigned.

U.S. Politics

Volunteer army

As regimental commanders, volunteer colonels were vital to American military efforts, raising units of volunteer soldiers who agreed to serve outside US boundaries. The came from western states, especially Illinois, Indiana, Kentucky, Arkansas, and Mississippi. Of the 63 volunteer colonels on active duty in 1846, 14 belonged to the Whig Party, indicating that Whigs were not monolithic in their opposition to the war. The colonels accumulated a mixed wartime record of leadership, and their backgrounds varied greatly. Some had no military experience prior to 1846, but others had graduated from West Point, served in the regular army, seen combat in war or on the frontier, or held rank in a state militia. The colonels also varied widely in holding political office before and after the war. Several of them were experienced politicians before 1846 who also held important offices after the war, showing that most colonels were recognized figures in their home states.[4]

Antiwar sentiments

Politically, the Democratic party rallied behind Polk and strongly supported the war. The Whig Party has opposed the annexation of Texas and generally opposed the war. Some spponents (like Army lieutenany Ulysses S. Grant) believed the war constituted an unjust aggression against helpless Mexico. Henry Clay and many Whigs opposed geographical expansion because they wanted vertical modernization (based on industry and banking), rather than more-of-the-same farmland. Antislavery elements in New England saw the war as a conspiracy by soputhern slave owners--called the Slave Power--to expand their holdings. (Historians after 1900 agreed that allegation was untrue.) Still other dissenters feared the war might undercut republican values by transforming the United States from a republic to a grasping militaristic empire. Typical opponents used several different arguments, to no avail.

Abraham Lincoln a new member of Congress from Illinois, was not a particularly powerful or influential figure, but he was articulate in denouncing the war, which he attributed to Polk's desire for "military glory — that attractive rainbow, that rises in showers of blood." He also challenged the President's claims regarding the Texas boundary and offered a resoltuion (which did not pass) demanding to know on what "spot" on US soil that blood was first spilt.[5] In January of 1848, he was among the 82 Whigs who defeated 81 Democrats in a procedural vote to add to a routine bill the words "a war unnecessarily and unconstitutionally begun by the President of the United States." The amendment passed, but the bill never reemerged from committee and was never finally voted upon.

Lincoln damaged his political reputation in Illinois with a speech in which he declared, "God of Heaven has forgotten to defend the weak and innocent, and permitted the strong band of murderers and demons from hell to kill men, women, and children, and lay waste and pillage the land of the just." Two weeks later, President Polk sent a peace treaty to Congress. While no one in Washington paid any attention to Lincoln, the Democrats orchestrated angry outbursts from across his district, where the war was popular and many men had volunteered. In one county, Democrats set up mass meetings that adopted resolutions denouncing the "treasonable assaults of guerrillas at home; party demagogues; slanderers of the President; defenders of the butchery at the Alamo; traducers of the heroism at San Jacinto." Warned by his law partner that the political damage was mounting and irreparable, Lincoln decided not to run for reelection. Instead in fall 1848 he campaigned vigorously for Taylor, the successful general whose atrocities he had denounced in January. Regardless, Lincoln's harsh words were not soon forgotten, and haunted him during the Civil War. [6]


Peace

On November 22, 1847, a new Mexican government announced the appointment of peace commissioners, who negotiated with Nicholas P. Trist, the American peace commissioner, to draw up the Treaty of Guadalupe Hidalgo, which was signed Feb. 2, 1848.

War Cost

Financially, the war cost the US $147 million, including $73 for direct costs, $64 million for veterans benefits, and $10 million in interest chargesa on war loans. A total of 101,000 American soldiers wre mobilized, including 27,000 regulars and 74,000 volunteers; the typicalvolunteer served for 10 months. Deaths in battle totalled 1549; another 11,000 died from disease and accident.[7] Mexican losses were much higher but accurate data is lacking.
