This collection contains an undated memoir - the second of two volumes - written by Corporal H. J. Eaton covering his service as a Union soldier during and immediately after the American Civil War from 1864 to 1867. Inside the front cover Eaton writes, “A sketch of Army life, or My days and nights on the battlefield, Vol. 2, Giving a Sketch of Battles, Scenes on the March &c by Corp. H. J. Eaton of Co. E 11th Reg. N.H.V. 2nd Brig. 2nd Div. Ninth Army Corps." In the memoir, Eaton discusses his personal experience, beginning in May 1864 after the Battle of Spotsylvania and continuing through the end of his service in the war. Towards the end of the volume, he notes the battles that were included in the memoir: Spotsylvania, North-Anna, Gaines Mills, Bethesda-Church, Cold Harbor, and Petersburg. Eaton also discusses other aspects of military life including marches, interaction with officers, and interactions with local residents. Eaton also briefly discusses General Ulysses S. Grant's headquarters. The last pages of the memoir are filled with poetry written by Eaton, friends, and other soldiers.
