There have been many books about Gettysburg, but never one to rival this in scale or authority. Based on extensive research, "The Gettysburg Companion" describes the battle in detail, drawing on firsthand accounts of participants on all sides in order to give the reader a vivid sense of what it was like to experience the carnage at Gettysburg in early July 1863. The many full-colour maps -- all specially commissioned for the book -- and the numerous photographs, charts, and diagrams make this book a feast for the eyes and a collector's dream.
