Nicely researched and well written, this book should make a reader want to see more from author Boggs.
It's quite a story, based on history, and a very sad history at that.
After the Yankees instigated the War, sometimes called "Lincoln's War" or "The War of Northern Aggression," both factually correct, but the best, most accurate, but more nearly objective term is "War Against Southern Independence," they discovered that by pulling all their military forces into the Southeast to pillage, burn, rape, and kill, they allowed the "Indians," the aboriginal peoples, to do the same to the residents of the West.
As the War progressed, and Confederate soldiers were captured, some of them were offered a parole of sorts: They could join the U.S. forces to fight but only against the "Indians," not against their fellow Southerners.
Most people used to know about the hell-hole known as Andersonville, the prisoner of war camp in Georgia where so many of the invaders were held. And so many died. (Confederate authorities begged the invading Yankees for a prisoner swap, knowing they couldn't feed, clothe, or care for the thousands. Northern authorities, not caring how many of their own people died, just said no. They saw some tactical and/or strategic advantage, even in letting their own thousands perish. But, of course, blamed the commandant of the prison and hanged him.)
But most people don't know how equally murderous the Yankee prisons were, and that Confederate prisoners also died by the thousands, often from intentional starvation and mistreatment.
Northern prisons were so terrible, so deadly, many of the Southerners decided it was preferable to risk their lives fighting the "Indians" than to risk them staying in the prisons.
That's where "Once They Wore the Gray" begins.
Author Boggs knows both his history and how to tell a dramatic fictive story.
I have no hesitation in recommending "Once They Wore the Gray," and I'm pretty sure I'll re-read it some day.
