Hats Off offers a concise history of U.S. Army headgear from the immediate post Civil War era to the eve of World War I. In this study historian John P. Langellier shares more than a quarter of a century of research in archives, museums, and private collections throughout the nation. An informative text is supported by nearly 400 illustrations of rare and important military headdress. The volume is destined to become a standard reference for collectors, curators, and those interested in American military uniforms from the Indian Wars through the early 20th century.

John P. Langellier received his BA and MA in History from the University of San Diego, and his PhD. from Kansas State University in Military History. He has written dozens of books and scores of articles related to American history.
