When Texas was annexed by the United States in 1845 Mexico's foreign minister in Washington, D.C. angrily left the country and returned to Mexico. Mexico had warned the United States that if Texas became a U.S. state it would be cause for war. By April of the next year a shooting skirmish had broken out along the contested border between Mexico and the state of Texas. -- General Zachary Taylor, who was in charge of the U.S. forces along the border alerted President James K. Polk with the message "Hostilities may now be considered as commenced." President Polk wasted no time, alerting Congress in protest that the Mexican soldiers had "...shed American blood upon American soil." --Congress quickly brought the United States to a war footing. Both nations were ill prepared for war. --Mexico with a much larger army seemingly had the advantage, however, the Americans were better trained, had state-of-the-art artillery, and possessed a navy that could move troops quickly as well as shell a coastal city into submission.--For nearly two years the Americans pushed deeper into Mexico, winning every major battle. -- General Scott, or "old fuss and feathers" as he was known, was a master tactician and with a much smaller army was able to defeat the Mexican soldiers led by General Santa Anna. --It was not until February 1848 when the treaty of Guadalupe Hidalgo was signed that the war came to an official end. The Americans gained much from the treaty, including the modern-day states of California, New Mexico, Arizona, Nevada, Utah, and parts of Colorado and Wyoming. For this vast territory the U.S. compensated Mexico with a little over $18 million. Though this war is seldom mentioned today, the Mexican-American War had a profound and lasting impact on both nations.
