Background of the Battle

Strategic Importance of Resaca de la Palma

Resaca de la Palma, located near the Rio Grande, was strategically significant due to its natural terrain and the presence of a dry riverbed (resaca) that provided a natural defensive position.

Context of the Battle

Following the U.S. victory at the Battle of Palo Alto on May 8, 1846, General Zachary Taylor sought to press his advantage and pursue the retreating Mexican forces.
