Remarkably, beginning with Brandy Station and ending at Falling Waters, the study compiles orders of battle (43 by my count) for Gettysburg Campaign clashes of all sizes, from brief battalion sized skirmishes to the mighty multi-day collision of armies. This has never been done before in a single volume. The amount of data contained in the OBs is also unique. Whereas most Civil War military history books simply list unit hierarchy and perhaps regimental commanders, Petruzzi and Stanley have gone the extra mile, presenting readers with unit strengths; casualties broken down into categories of killed, mortally wounded, wounded, wounded and captured, captured, and missing; loss percentages for each unit; unit commanders and their replacements; and gun types for the batteries. Appreciative of those that have gone before them, the authors have also plowed their own research into the project. While the OBs are not sourced in the form of footnotes, the authors assure us that O.R. reports and rosters located in the National Archives have been consulted, as well as "manuscripts, magazine and newspaper articles, and letters and diary entries written by participants" (pg. VII). The methodology in terms of how they arrived at the numbers is perhaps not as formalized as some might wish, but the authors do denote with an "(est.)" those entries with a particularly high amount of guesswork involved.
Summaries of all the battles and skirmishes supplement each OB and the vast majority also benefit from the brilliant multi-color cartographic renderings of Steven Stanley. The maps are such an integral part of the book, one might also consider it an atlas. If readers wonder why a publisher would want to compete with its own catalog in this way, it should be remembered that there's as much variety in mapmaker content, style, scale, and emphases as there is with narrative historical writing, so it never hurts to add another perspective. Complaints are few in number and include repeated use of identical photos (sometimes only pages apart) and occasional lapses in copyediting and proofreading.
The Gettysburg Campaign in Numbers and Losses is a true one of a kind creation and a very useful addition to the Gettysburg reference library. Hopefully, publisher Savas Beatie does not consider this a one off enterprise but rather the beginning of another long running series.
