Best Answer

Mexico severed diplomatic ties to the United States after the U.S. annexed Texas, and started a low-intensity conflict along the US-Mexico border, which actually, was ill defined -- Americans believed the border to be the Rio Grande River, while Mexicans thought it was the Nueces River, several miles to the north.

This resulted in skirmishes between Mexicans and Americans, resulting in American blood spilled in this no man's land. This was used by president Polk as a casus belli to start the war. He however, was uninterested in Texas: he wanted to "acquire" California from Mexico at any cost.

The war between the United States with Mexico lasted from 1846-1848. In 1846, the Alamo mission was totally destroyed by the Mexican forces. "Remember the Alamo" became a rallying cry among the US forces.
