Query: The Significance of the Bloody Crucible of Courage

Whether or not one agrees or disagrees with Brent Nosworthy's conclusions in The Bloody Crucible of Courage is not the point. What Civil War enthusiasts must appreciate is that if you want to understand the study of Civil War tactics, if you want to know the state of the question about the rifle revolution, you must read this book. If you do not read this book, you can not be an informed participant in the current debate.Do I agree with all of his conclusions? No, but this book has made me reexamine the subject and ask new questions. More research needs to be done before we can reach more conclusive answers, but that new research must deal with the issues raised in The Bloody Crucible of Courage.
