The point of the book seems to be twofold. It is a concise but thorough account of Forrest's entire military career. Few Civil War book have these many maps. There seems to be one every few pages, which aids the direct, if colorless prose. At the same time, Scales' argues that Forrest was a remarkable soldier. Boosting Scales' argument is his unwillingness to engage in mythologizing and his willingness to point out Forrest's missteps and flaws.
It is not that the book makes new arguments, but rather that there is none that is this comprehensive. The result is a book that, despite its thin research, should be the starting point for anyone wanting to follow Forrest's career and development as a commander.
