This book examines what the citizen soldiery of the Mid-Atlantic states wore when they marched off to save the Union in 1861. An exhaustive search of thousands of newspapers has provided a myriad of reports and personal accounts from soldiers' letters which offer a hitherto unpublished view of the stirring events during the first few months of the Civil War. Combined with fascinating detail from numerous diaries and regimental histories, this has helped reconstruct the appearance of the Union volunteers of Pennsylvania, New York, New Jersey, Delaware, Maryland, and the District of Columbia. The book is enhanced by photographs of original items of uniforms from private collections, plus imagery of the day, which show with remarkable clarity the great variety of clothing and headgear worn. Sponsored by the Company of Military Historians, this is an essential reference for collectors, living historians, modelers, and curators, as well as anyone with a general interest in the Civil War.
