Detailed information on the Mexican Army which fought the Texans in the 1830s, and the US Army in its first important foreign war ten years later, is notoriously elusive. In this ground-breaking book an internationally respected military historian presents a mass of new information from Mexican archives and a variety of other contemporary sources. For the first time the armies of the notorious General Santa Anna are explained coherently for the English-speaking reader, and their frequently changing and unevenly issued uniforms are illustrated with early prints, portraits, photos of rare surviving items, and meticulous colour reconstructions.
