James M. Thomson, a private of Company F 6th Iowa Cavalry, kept a diary of his experiences in what he identified as the “Three Year War with Indian in Dakota.” Most of his entries are brief one or two line notes in pencil. His entries concerning the Battle of Whitestone Hill included a great deal of detail taking up five pages of his pocket-sized diary. These pages have been transcribed exactly has Thomson wrote them. Only a few periods have been inserted and the spelling of a few words have been changed for clarity.
