Hmmmm? Then why were the first battles of the Mexican War were in California, not in Texas? It was not about the Texas border --- it was about getting the land we had tried to purchase from Mexico years before.
The first battle, as in the one that caused America to declare war, was on May 8, 1846 in Palo Alto after the Mexican army crossed the Rio Grande into Texas.
