USA HISTORY

Detailed explanation-1: -The Americans took the offensive, invading Mexico on three fronts: from the north through Texas, from the east through the port of Veracruz, and into the west (present-day California and New Mexico). The Americans won every major battle of the war, mostly thanks to superior artillery and officers.
