Mapping the Conflict
The lower Rio Grande Valley was the stage for much of the early action during the war. The armies of Zachary Taylor and Mariano Arista battled each other several times in these early stages. They clashes ranged from the riverside action at Rancho de Carricitos to the artillery duel at Palo Alto. Both armies fought desperately for control of the area. The series of battles would leave Zachary Taylor’s army primed to pursue a prolonged campaign in northern Mexico.
