This work, originally published in 1915, was authored by Col. G. J. Fiebeger, Professor of Engineering at the United States Military Academy for the use of its cadets. Col. Fiebeger employs an engaging approach to better understand this historic event. By using extensive quotes gleaned from battle reports of the campaign¿s chief participants, he allows the eyewitnesses to tell their story. Descriptive accounts are from the planners of the campaign and from a broad segment of its top commanders. Their quotes reveal their thoughts in context with the information they knew at the time. They explain the reasons for their decisions, in detail, and how this historic event unfolded from beginning to end. Quotes used are seamlessly connected chronologically, using both sides' perspectives, to provide a well-rounded view of why vital decisions were made. This reprint includes new artwork, maps, and charts to enhance the original edition and makes an important contribution to the bookshelves of Gettysburg enthusiasts.
