This collection contains correspondence, documents, and typescripts related to Byron D. Paddock's service in the 1st Michigan Light Artillery Regiment, Battery F, during the Civil War. Manuscript letters, reports, and orders largely pertain to the regiment's actions during the Atlanta Campaign of 1864 and in its immediate aftermath, including the siege and surrender of Atlanta. A typescript includes extracts from published works regarding the 1st Michigan Light Artillery Regiment, a muster roll for Battery F with information about each soldier's disposition at the end of the war, and a Paddock's war diaries. The diaries concern Paddock's experiences between January 1, 1862, and April 15, 1865, particularly with regard to camp life, target practice, movements and marches, engagements with Confederate forces and batteries, and celebrations at the end of the war. A gap from September to October 1864 coincides with Paddock's furlough.
