I actually read the Kindle edition, which isn't listed as an edition. Anyway...
I thought the book was interesting in its way. I wasn't too sure about whether some of the terminology would be considered not very sensitive today, like the frequent use of the phrase "amputated men." I know the labeling at the time was much worse.
One thing that struck me is how much the "Lost Cause" mythology had affected my views, considering that I'm someone who's always lived in the North. Not that I especially bought into the story of how Confederate soldiers were tragic and heroic, and fighting for a noble cause, but the influence of the idea was certainly floating around as I grew up.
I got the sense that there was broad agreement at the Federal level that the United States government wouldn't be giving pensions to the "traitors" who fought for the Confederacy. Conditions got better once there was a "redemption." I wondered if this was when the Southern states that had seceded were again in charge of their state governments. Certainly Andrew Johnson was all about forgiving Confederates. But otherwise, the Federal government wasn't going to reward traitors.
Most of the state governments of states that had seceded, and some border states, eventually gave disabled Confederate soldiers pensions. At first Benevolent Societies had helped, but private groups moved towards weaving the Lost Cause mythology, and most disabled soldiers weren't too into the myth, apparently. But there was interest in providing prostheses to amputees, at first through those private benevolent organizations, and then from the state governments.
I was struck by how much "history rewritten" had made it harder to challenge Southern tenets that had solidified by the twentieth century. During and right after the Civil War, too soon for the history to be rewritten, there was a lot more clarity about who had fought to preserve the Union, and who had fought to keep the slaveholding system in place.
