For anyone who's looking for a deeper understanding of ACW battles, let me recommend a series of books. For brevity's sake, I'll refer to them as "The Maps" series. They are unique in that just about every other page in the book is a map which accompanies a narrative on the facing page. I've found them remarkably helpful in sorting out the details of complex engagements like Antietam, Gettysburg, Chickamauga, and the Wilderness Campaign. Deciphering such actions, as viewed through page after page of text, had always left me confused and a bit frustrated. I forever found myself turning back (or forward) to the accompanying reference diagrams looking to flesh out my understanding of the associated events. Well, no more. If you want to get a good handle on a corner of one of these battles, the fighting around McPhereson's Ridge at Gettysburg, for instance, these books will tie up the loose-ends for you. Here's a pic of the Gettysburg volume:

Other Volumes include
The Maps of Antietam,
The Maps of Chickamauga,
The Maps of the Wilderness Campaign and
The Maps of First Bull Run. I'm really hoping to see additional volumes for less well-known engagements in the future.
