I bought this book thinking I would get two great biographies in one about two of the most fascinating leaders in history. The information that was provided on both of them was simply nothing new. What bugged me the most about this book, however, were the "lessons" a leader was supposed to learn from the mistakes and/or good decisions that each of them made.
I couldn't find a "lesson" that was ever presented with more depth than "Lee did this and showed good leadership. Do what Lee did and you'll be a good leader too."
Aacckkkkk! I found myself not concentrating on the book itself because of these simplistic statements so I finally quit reading it.
If you're looking for a good biography and comparison of Lee and Grant, this is not your book.
