Mexican American War
One of the major issues in James Polk's campaign during the Election of 1844 was the annexation of Texas. In 1845 the Republic of Texas became the state of Texas. Although Mexico had never recognized the independant Republic, it had done almost nothing to reclaim the territory and Santa Anna was in exile. In late 1845, Polk reassigned Zachary Taylor to Louisiana in preparation to insured Mexico respected the new borders of the United States.
Further aggrevating the situation was Mexican political turmoil. John Slidell, representing the United States, had journeyed to Mexico City with an offer to buy additional Mexican territory in the Southwest and along the Pacific Ocean. His creditials were never accepted and Slidell was forced to return to the United States.
In March, 1846, American forces moved to the southern border of Texas, the Rio Grande River. The only problem was that Mexico recognized the Nueces River as the border. On April 23, 1846 Taylor ordered Captain Samuel Thorton to advance with his and William Hardee's companies of dragoons to reconoitter a 22-mile stretch of the Rio Grande. More than 1,500 Mexicans attacked the dragoons on April 25.
