The elite French Zouaves, with their distinctive, colorful uniforms, set an influential example for volunteer soldiers during the Civil War and continued to inspire American military units for more than a century. Hundreds of militia companies adopted the flamboyant uniform to emulate the gallantry and martial tradition of the Zouaves. Drawing on fifty years of research, this volume provides a comprehensive state-by-state catalog of American Zouave units, richly illustrated with rare and previously unpublished photographs and drawings. The author dispels many misconceptions and errors that have persisted over the last 150 years.
