The Mexican-American War between the United States and Mexico began with a Mexican attack on American troops along the southern border of Texas on Apr. 25, 1846. Fighting ended when U.S. Gen. Winfield Scott occupied Mexico City on Sept. 14, 1847; a few months later a peace treaty was signed (Feb. 2, 1848) at Guadalupe Hidalgo. In addition to recognizing the U.S. annexation of Texas defeated Mexico ceded California and , New Mexico (including all the present-day states of the Southwest) to the United States.
　　The Mexican-American War was the first major conflict driven by the idea of "Manifest Destiny"; the belief that America had a God-given right, or destiny, to expand the country's borders from 'sea to shining sea'. This belief would eventually cause a great deal of suffering for many Mexicans, Native Americans and United States citizens. Following the earlier Texas War of Independence from Mexico, tensions between the two largest independent nations on the North American continent grew as Texas eventually became a U.S. state. Disputes over the border lines sparked military confrontation, helped by the fact that President Polk eagerly sought a war in order to seize large tracts of land from Mexico.
　　As with all major events, historical interpretations concerning the causes of the Mexican War vary. Simply stated, a dictatorial Centralist government in Mexico began the war because of the U.S. annexation (1845) of Texas, which Mexico continued to claim despite the establishment of the independent republic of Texas 10 years before. Some historians have argued, however, that the United States provoked the war by annexing Texas and, more deliberately, by stationing an army at the mouth of the Rio Grande. Another, related, interpretation maintains that the administration of U.S. President James K. Polk forced Mexico to war in order to seize California and the Southwest. A minority believes the war arose simply out of Mexico's failure to pay claims for losses sustained by U.S. citizens during the Mexican War of Independence.
　　The Mexican-American War was largely a conventional conflict fought by traditional armies consisting of infantry, cavalry and artillery using established European-style tactics. As American forces penetrated into the Mexican heartland, some of the defending forces resorted to guerrilla tactics to harass the invaders, but these irregular forces did not greatly influence the outcome of the war.
　　After the beginning of hostilities, the U.S. military embarked on a three-pronged strategy designed to seize control of northern Mexico and force an early peace. Two American armies moved south from Texas, while a third force under Colonel Stephen Kearny traveled west to Sante Fe, New Mexico and then to California. In a series of battles at Palo Alto and Resaca de Palma (near current-day Brownsville, Texas), the army of General Zachary Taylor defeated the Mexican forces and began to move south after inflicting over a thousand casualties. In July and August of 1846, the United States Navy seized Monterey and Los Angeles in California. In September, 1846, Taylor's army fought General Ampudia's forces for control of the northern Mexican city of Monterey in a bloody three-day battle. Following the capture of the city by the Americans, a temporary truce ensued which enabled both armies to recover from the exhausting Battle of Monterey. During this time, former President Santa Anna returned to Mexico from exile and raised and trained a new army of over 20,000 men to oppose the invaders. Despite the losses of huge tracts of land, and defeat in several major battles, the Mexican government refused to make peace. It became apparent to the Polk Administration that only a complete battlefield victory would end the war. Continued fighting in the dry deserts of northern Mexico convinced the United States that an overland expedition to capture of the enemy capital, Mexico City, would be hazardous and difficult. To this end, General Winfield Scott proposed what would become the largest amphibious landing in history, (at that time), and a campaign to seize the capital of Mexico.
　　CONSEQUENCES OF CONFLICT:
　　1. The United States acquired the northern half of Mexico. This area later became the U.S. states of California, Nevada, Arizona, New Mexico and Utah.
　　2. President Santa Anna lost power in Mexico following the war.
　　3. U.S. General Zachary "Old Rough and Ready" Taylor used his fame as a war hero to win the Presidency in 1848. A true irony is that President Polk, a Democrat, pushed for the war that led to Taylor, a Whig, winning the White House.
　　4. Relations between the United States and Mexico remained tense for many decades to come, with several military encounters along the border.
　　5. For the United States, this war provided a training-ground for the men who would lead the Northern and Southern armies in the upcoming American Civil War.
　　UNIQUE FACTS OR TRENDS:
　　1. This war featured the first major amphibious landing by U.S. forces in history.
　　2. The defeat of Mexico was the first time an enemy force occupied the capitol of the nation. The French would also occupy Mexico City in the 1860's.
　　3. Despite early popularity at home, the war was marked by the growth of a loud anti-war movement which included such noted Americans as Ralph Waldo Emerson, former president John Quincy Adams and Henry David Thoreau. The center of anti-war sentiment gravitated around New England, and was directly connected to the movement to abolish slavery. Texas became a slave state upon entry into the Union.
　　4. One interesting aspect of the war involves the fate of U.S. Army deserters of Irish origin who joined the Mexican Army as the Batallón San Patricio (Saint Patrick's Battalion). This group of Catholic Irish immigrants rebelled at the abusive treatment by Protestant, American-born officers and at the treatment of the Catholic Mexican population by the U.S. Army. At this time in American history, Catholics were an ill-treated minority, and the Irish were an unwanted ethnic group in the United States. In September, 1847, the U.S. Army hanged sixteen surviving members of the San Patricios as traitors. To this day, they are considered heroes in Mexico.
　　5. In Mexico, a special day is remembered to celebrate the bravery of the teenaged military cadets at the military academy at Chapultepec Castle, which was attacked by Scott's army on September 13, 1847. "Dia de Los Niños Heroes de Chapultepec" ("day of the boy heroes of Chapultepec), is commemorated every year on the anniversary of the battle.
　　Ordered to retreat by their Commandant, these young cadets joined the fight- the boy heroes who are honored every year are the four teenaged cadets (Francisco Marquez, the youngest, was thirteen years old!) and their lieutenant squadron leader, Juan de la Barrera, (the oldest, age 20), who lost their lives in that battle.
　　As late as 1880, the "Republican Campaign Textbook" by the Republican Congressional Committee described the war as "Feculent, reeking Corruption" and "one of the darkest scenes in our history - a war forced upon our and the Mexican people by the high-handed usurpations of Pres't Polk in pursuit of territorial aggrandizement of the slave oligarchy".
