Book excerpt: Historians have given much attention to the Civil War’s prominent players—its generals, politicians, and other public leaders—but they have devoted less attention to the common soldiers and civilians—the “plain folk”—who actively participated in the conflict. In his study of popular thought during the Civil War era, Randall C. Jimerson offers a grass-roots perspective on the war by examining the thoughts and ideas of these ordinary men and women. The Private Civil War derives much of its power from the author’s deft use of personal letters and diaries. Separated from home and family, virtually every soldier and many civilians wrote frequent and informative letters or recorded daily experiences and thoughts in journals. Jimerson has consulted a broad cross section of these documents, culling information from letters and diaries written by people from every state and from all social classes and military ranks. These documents, remarkable in many instances for their depth of feeling and eloquence, provide rich, detailed information about sectional perceptions and ideology as well as many private reflections.
