For me, the best thing a novel can do is to lift me out of my reality and into one of the author's creation. Blair Howard's Chickamauga did exactly that. It took me to a time and introduced me to people who lived, fought, and died a long time ago. I could smell the powder in the air, see the shadows cast by lanterns inside leaky tents, hear the restless stamping of nearby horses, and feel the rush of terror of a new recruit marching into his first battle. Beautifully done.
Chickamauga is meticulously researched and written without apparent bias toward either side's cause. As a casual reader of civil war fiction with a definite bias toward one regiment's history, I struggled a bit with all the names and the contrasting viewpoints. Personally, I would have liked to have more time to settle into some of the individual stories before transitioning into another. However, once I did become more familiar with the characters, I was able to follow both them and the action.
I would definitely recommend Chickamauga to anyone looking to learn more about this battle and those who fought in it. It's almost like being there.
