The WMU United States Civil War Collection consists of 8 diaries and 29 letters from the collections at the Western Michigan University Archives and Regional History Collections. They were written in the mid 1860s by men with connections to Michigan and the Midwest, regimental or residence, and represent diverse military experiences, ranging from a musician to a prisoner of war situation. The handwritten originals have full transcriptions that are searchable with comprehensive metadata and include page images.
