This book is the definitive work about a little known part of our history -- the Indian Wars of 1865 on the Western Plains. Abraham Lincoln supported a move to draft Confederate prisoners of war languishing (and often starving) in Northern prisons, with the stipulation that they would not have to go South and fight fellow Confederates. The "Galvanized Yankees" (so named because it was thought that their loyalty to the North was only a thin "ganvanized" layer) -- 6,000 of them, took the oath of loyalty to the Union and headed West to guard stagecoaches and mail routes. Numerous fights with Plains Indians, bitter cold, at lonely outposts were but a few of the hazards the Galvanized Yankees faced. My gg grandfather survived all this and returned home in 1866. I recommend this book to anyone that is interested in learning more about these brave men who chose service to the Union rather than almost certain death in Northern prisons.
