The next issue of Blue and Gray Magazine (Vol. 25, Issue 2 - Summer 2008) will be the final piece of a five-part series covering the campaign and battle of Chickamauga by noted expert William Glenn Robertson. I understand it was a rough year as a subscriber if you have no interest in the battle, but I can't recommend the issues highly enough. This whole series has been an example of the best of military magazine publishing in long form. Put together, the magazine has basically issued a new Chickamauga "book". Here is the Table of Contents (.pdf format) for part 5.
It's been a treat that should tide anyone over until Dave Powell finishes his Chickamauga map study.
