This collection consists of seven manuscript diaries, pocket-size notebooks written while Asa Sackman was serving in the 44th Regiment, Companies F and G, of the Ohio Volunteer Infantry. The diaries date from October 1861, his first month of service, through September 1862. Sackman writes almost daily about the company's movements and actions, the weather, and camp life in the winter, and describes encounters and battles with Confederate troops, prisoners, and deserters. Events take place in West Virginia (with one foray into Virginia) and include the Battle of Lewisburg (May 23, 1862) and the Battle of Charleston (September 13, 1862). There are also mentions of the Battle of Roanoke Island and the Expedition to Logan Court House as well as many of Sackman's fellow soldiers at Camp Piatt and subsequent camps in what became West Virginia.
