I picked up this book for free at a coffee shop a couple of years ago. The imagery and authenticity of characters was striking, and the passion of the author for his subject was unmistakable. I found myself caring about both the events and the author, and the fleeting nature of the time and place portrayed.
The book is not an "easy" read - the scholarly dedication to detail, the dated vernacular, and the (relative) obscurity of the subject kept me on my mental toes the whole way through. That had its own reward though, and I highly recommend the read.
If you can find Rags Of Glory, buy it. Although our household gives away 20+ books each month, this is one of 5-10 with which I won't part.
