Armed with a broad range of Mexican military documents and previously unknown US sources, Douglas Murphy provides the first balanced view of early battles such as Palo Alto and Resaca de la Palma. He reassesses previously covered territory and also poses new questions.
Why did Mexico establish its defenses south of the Rio Grande while claiming territory north of the river? What was Mexico’s strategy in the campaign against the United States? What factors most affected Mexico’s defeat?
In confronting these questions, Murphy shows that the campaign was a complex chess match with undercurrents of political intrigue, economic motivations, and personal animosities as much as military action. Two Armies on the Rio Grande will transform our understanding of the US-Mexican War.
