Query: AN EYE-OPENER TO POST-MILITARY POLITICS

Generally, historians write battle engagements of Longstreet as slow-moving, and his preference to defensive strategy. This is particularly alleged for his part at Gettysburg but visiously-so by a few of Longstreet's contemporaries after Lee, who never publicly made such charges, had died. So, the author challenges the reader to consider the effects of politics that followed the war and resulted in Longstreet's "tarnishment." This book prompted me to read "Lee and Longstreet at High Tide" by Helen Longstreet, his second wife. With an obvious love-interest in preserving his reputation, she nevertheless makes very convincing and record-based arguments that basically support this book. I recommend her's as follow-up reading to this.
