Santa Ana’s inability to secure consistent support from local militias weakened the Mexican defense.

6. Urrea’s Irregular Warfare

Urrea’s tactics, often described as “hit‑and‑run”, leveraged speed, surprise, and local knowledge. His raids into Texas disrupted U.S. supply lines and forced the Americans to divert resources. Urrea’s success at San Patricio highlighted the potential of irregular warfare against a conventionally superior opponent And that's really what it comes down to. Simple as that..

Scientific or Theoretical Perspective

Here's the thing about the Mexican‑American War can be examined through the lens of strategic theory and international relations. Realist theory emphasizes power politics and the pursuit of national interest—Polk’s expansionist agenda exemplifies this. Which means Offensive realism predicts that a rising power (the U. S.) will seek to dominate its region, leading to conflict when faced with a weaker, less unified adversary (Mexico).

From a military science perspective, the war illustrates the transition from 19th‑century linear tactics to more flexible, combined‑arms operations. Scott’s use of amphibious landings, artillery coordination, and logistics foreshadowed modern expeditionary warfare. Conversely, Mexican commanders like Urrea demonstrated the enduring potency of irregular warfare and the strategic value of local knowledge Worth knowing..
