Peter Tsouras has assembled a formidable group of contributors for "Dixie Victorious," his anthology of counter-factual scenarios describing how the South could have won the Civil War. Each individual chapter/scenario is well-researched and well-written, and often the ideas are imaginative. The book also manages to explore how the Confederacy could have won the war without lionizing the South, an important distinction for works of this kind.
Even so, the book is a mixed bag in terms of the quality of its alternate histories. Chapters 1 and 2 are an excellent contrast and example (SPOILER ALERT!). In the first chapter, Andrew Uffindell describes just how the British and French might have become involved in the Civil War by making two small, plausible changes: 1) Prince Albert, who played an important role in moderating the British response to the Trent Affair, is killed in a carriage accident prior to that international incident (and the accident in question actually happened); 2) The Trent Affair itself turned violent and ugly, and some British sailors were killed as a result. Most of the story that follows is plausible, accurately detailed, imaginative (I especially like the ultimate fate of George Armstrong Custer), and logical. You can argue with some of the details, but not the thesis.
On the other hand, Wade G. Dudley's second chapter on how the South could have won the war if it banked everything on building a Navy is bad alternate history, violating most of the important rules for constructing a counter-factual scenario. None of the changes involved are small or plausible: his chapter requires CSA Secretary of the Navy to advocate major changes of policy that he did not imagine in real history, and to persuade President Davis, the Confederate Congress and the Confederate governors (the latter he forgot about completely) that he was right and get their full support. That is a major, implausible change to start with, on the scale of Lyndon Johnson deciding to withdraw from Vietnam.
His description of the development of a major naval industrial center in New Orleans in less than a year is implausible, even with the help imported machine goods, because we know how long it took the Confederacy to undertake projects of equal or lesser size elsewhere. His scenario of building the Virginia plus two fictional ironclads in Norfolk would require the diversion of most or all of the output of the Tredegar Ironworks, with potentially devastating consequences elsewhere, but Dudley ignores this very obvious and salient fact (although he does gloss over that Tredegar was not initially tooled to make the necessary plate armor). Finally, it assumes that Lincoln would still allow McClellan to go forward with the Peninsular Campaign, or that the cautious-to-a-fault McClellan himself would even want to in the face of well-established Confederate efforts to build a powerful Navy. Dudley's scenario is therefore plagued by not one major, implausible change to make it work. It has four of them!
About 1/3 of the scenarios in "Dixie Victorious" are of the Dudley model: they fall into the realm of entertaining, but ultimately uninstructive fantasy. While fun to read, they are not at all useful in showing how the Confederacy could have won the war, and are therefore not good examples of alternate history. If you read "Dixie Victorious," I recommend buying Roger Ransom's "The Confederate States of America: What Might Have Been" alongside it. That book is more in the vein of Uffindell's work than Dudley's, and will serve as a useful counterpoise to some of the flights of fancy found in Tsouras's anthology.
It is those flights of fancy that earned this book a three-star rating. It is above average, and it is certainly entertaining. However, some of the arguments made in the book are deeply flawed.
