The Mexican-American War: Effects The War Exploded: Once war was declared on Mexico, the U. S. strategy called for
a three-pronged offense. The Army of the West would take New Mexico and
California; the Army of the Center would take northern Mexico; and the Army of
Occupation would march into Mexico City. Although the Mexican forces fought
valiantly, the U. S. forces beat them definitively in battle after battle. After a year
and a half of fighting, the war ended when a peace treaty was signed in Guadalupe
Hidalgo, a village a few miles outside of Mexico City.
