The high Sangre de Cristo Mountains of New Mexico seemed an unlikely site for a desperate Civil War battle, but on March 28, 1862, the army of Gen. Henry Hopkins Sibley, seeking to conquer the West for the Confederacy but dangerously short of supplies, fought a costly battle at Glorieta Pass with Federal forces.The Rebels seemed to have won, and Union units withdrew, but as fate would have it, Federal cavalry under Col. John Chivington unexpectedly found the Confederate supply train and destroyed it, leaving the Southern soldiers isolated and defenseless.After a few additional skirmishes, the dispirited and disorganized Rebels straggled back to Texas and abandoned their quest for expansion into the Southwest. The Battle of Glorieta marked the Confederacy's farthest advance northward in the Far West.Combining documentary history and first-person accounts with field research and discovery of artifacts, Don E. Alberts provides clear detail on the battle, including the precise locations of events and of particular units. He marshals evidence to reach the startling, yet now inevitable, conclusion that the Battle of Glorieta was indeed a clear and significant Union victory.The Battle of Glorieta offers a full, detailed, and accurate history of this blind, groping struggle in the smoke-filled mountain valley.
