Excellently written behind the scenes history
Format: Paperback
This is one of the best books on the irony of the Civil War. It is a different perspective that focuses on the misjudgement and arrogance of the confederacy. Food wars and manipulation of the slaves they were not part of their ill-conceived strategy to establish a states based totally on inequality. Too bad that today's politicans are trying to repeat the same mistakes. I would highly recommend this book to students of the Civil War and anybody who looks at today's politics and wonders where their southern strategy got its roots.

Women and slave power in the C.S.A.
Format: Paperback
Fascinating, well documented description of the influential roles played by women and slaves in the Confederated States of America. The author demonstrates that the principal focus of the C.S.A. was first and foremost on the preservation of its 'peculiar institution', i.e., slavery, and the how this, along with the increasing politization of women, undermined its viabilty in many ways. The author's style is a bit turgid and academic at times, but well worth the effort to gain a better understanding of the Civil War from the South's perspective.

I really enjoyed the premise of this book
Format: Hardcover
It seems to me that, it was a book just waiting to be written. The author covers topics very rarely considered in any detail in other books on the Civil War. She helps cut through some of the romantic mysticism and points out reasons why, as we all suspected, that most of the South (especially the poor) were very much victims of the Confederacy. She also explains in greater detail the way of thinking of the Planter class of the Old South, which still exists today--you can even hear it in the speech of the elites of the Deep South today. The problem I had with this book, is that the author repeats herself. Some here have said that they don't understand why people are saying that. Let me paraphrase just a couple examples of what I mean. She says , in one paragraph, that "soldiers wives started to become a political constituency for the first time" and explains how. A paragraph later, she ends the paragraph with "becoming a political entity was something new for poor white soldiers' wives". On the next page it says "for poor soldiers' wives, the Civil War was a huge burden, and they came into their own politically". In three pages she might say, "the term soldiers' wives' began to take on political meaning for the first time". Now, that is not repeating yourself with the same words, exactly. But it is repeating concepts that are not that hard to grasp. The book could have been much shorter and, IMHO, much better. I am not sure why the author feels the need to repeat certain points over and over. Another concept "done to death" was how the Planter class had not considered that a full 1/3 of their population would not only not be soldiers, but also would , in all likelihood, be opposed to them. Now, this would seem obvious to us now, so it is important that she point it out. But once is enough. I hope I am explaining the "repetition problem" a little better here....the topic and concepts were great. Repeating concepts over and over made for, in some places, a very long read.

Fascinating Social History of the Confederacy
Format: Paperback
This was hard to get into in the first chapter. It became more and more readable. It provides a critical look at the untold stories of women and slaves in the Civil War-the powerless. It shows how poorly conceived the whole Confederate experiment was. When Jefferson Davis said that the Confederacy would have written on its tombstone "Died of a Theory", he could have said "Died of Many Half-Baked Theories" about the rights of the powerful over the powerless. There should be much more written about the social history of the Confederacy. One of the more interesting points the book makes is how little the Southern people had to do with the secession of most of the states. This was a tragedy of immense proportions.

Helpful!
Format: Kindle
What a needed text for the canonical sciences. The glossary and footnote comments were most helpful. The definition of law is most excellent.
