A comprehensive, authoritative handbook on the Civil War which should be an essential reference tool in all public libraries, school and college libraries, and reference libraries used by students of the Civil War. The more casual Civil War buff who reads most of the books- popular and scholarly- on the subject, will find it indispensable. The text runs to about 1000 pages; there are 4000 entries of which half are biographical, covering personalities involved directly and indirectly in the war. Twenty major campaigns, and as many minor ones, battles, skirmishes, engagements -- are given due coverage. While military organization, weapons, political events attendant on or related to the war are identified and concisely treated. Cross references insure interrelated events and personalities complete recognition- as for example under Harper's Ferry, there is a cross reference to two major articles- Antietam and John Brown, etc. Illustrated with maps and diagrams. The compiler of this useful reference work is the fifth regular Army officer in his immediate family; served in World War II and the Korean War; taught military history at West Point, during which time his research for this book was accomplished, and now is serving on the staff of SHAPE in Paris.
