Europa Militaria publishes many very accurate books on period military. This book is quite good in respects to uniforms, weaponry, flags, and formations. Due to the fact that so many people are re-inactors the absolute period accuracy could not be followed. Most of their books are exact. This one has soldiers of the 1860's with modern glasses and one close-up photo with the soldier smoking a filtered cigarette. Still, a worthy book for the money if dress and arms are your focus.
