Line of the Rio Grande
"A history of the Rio Grande Valley in the years 1861-65 is largely a recounting of the struggle to control the region and the trade in cotton. This study in succeeding chapters will recount and evaluate the military movements along this Texas-Mexican border. Examination will be made of the objectives, successes and failures of governments, international political and diplomatic bodies, outlaw bands, commercial empires and individuals caught up in the web of cotton, guns and profits. Effort will be made to evaluate the successes and failures of each of these elements and their influence upon the course of the American Civil War"--Page 11-12.
