I am beginning a collection of American Civil War figures in 28mm. I have a few texts already, however I just bought a copy of Don Troiani's "Regiments & Uniforms of the Civil War" for it's amazing illustrations of uniforms of the American Civil War. I recommend it strongly to anyone interested in the period. Troiani is a great artist and he does his research thoroughly. I feel very confidant using this volume as a major reference.
