A participant chronicle traces the organization, recruitment, and service of an Ohio volunteer regiment, following its marches and engagements from mustering through major campaigns and battles across the western theater. Personal recollections describe mobilization, battlefield action at Chickamauga, the siege of Chattanooga and assaults on Lookout Mountain and Missionary Ridge, the East Tennessee operations including the march to Knoxville, and the Atlanta-to-Nashville campaigns, while noting hardships, leadership decisions, and comradeship. The work concludes with company-by-company rosters, field and staff listings, and a roll of honor; the author acknowledges imperfections and reliance on memory while aiming to preserve the regiment's experiences.
