I'm divided about this book. It's hard to complain about any book that has 87 good maps of Civil War campaigns. Add to this that these particular campaigns are rarely touched upon in any detail. The text accompanying each map offers reasonable coverage of each phase of the particular campaign or engagement. The whole forms a reasonably coherent whole covering the period from August 1863 through February 1864.
The book is flawed, mostly because of choices made in the maps themselves. The initial set of maps shows a fundamental problem. They set the stage for the discussion and subsequent maps. The area covered, primarily the the triangle between the Rappahannock and Rapidan Rivers in Virginia, saw significant maneuver during the period covered. Yet when you look at Map 1.3 The Battleground, there are two obvious things missing. Neither Bristoe Station nor Mine Run are shown on the map. The location of Bristoe Station is shown in the extreme lower right corner of the map. Map 4.1 illustrates the problem well, with the block representing the Union Fifth Corps mostly off the map. The ultimate destination of the Army of the Potomac, the area around Centreville, is not on the map at all. Similarly, while Verdiersville and the location of Mine Run appear on the far left edge of the overview map, the run itself is not indicated. This is a basic failure.
Similarly, the orientation of individual map sets makes no particular sense. The overview maps have North oriented towards the right page edge, which initially seems a little strange but is a reasonable choice. Other sets of maps have North oriented towards the top of the page, which is fairly natural. Then the maps covering the battle of Auburn (Maps 3.9-3.12) have North oriented towards the left page edge. The maps would work as well with either of the other two orientations. As they are, they present a false impression of the direction of advance and retreat. Map Set 8 has the same North is left orientation. The Payne Farm Map Set 10 have their own orientation, with North to top left corner. This orientation makes some sense due to the particular line of the battle, but it could be handled reasonably well with the North-top configuration. Finally, the Morton's Ford Map Set 13 has its own unique orientation for no reason that I can see. Again, it's a basic rule to have consistent map orientations unless otherwise is absolutely necessary.
There are also a number of copy editing errors that are particularly notable in the text accompanying parts of Map Set 10, where reference numbers in the text are out of sync with those shown on the maps. Apparently an editing pass after receipt of the final maps was missed. Gottfried also confuses WHF Lee and Fitzhugh Lee.
I'm torn as to whether or not to recommend this book. The strengths likely outweigh the flaws, but they are such basic and preventable flaws.
