Book excerpt: The Eighth Connecticut Infantry was one of the longest-serving Union volunteer regiments in the Civil War and saw action throughout the Eastern Theater, from Burnside's expedition in North Carolina to the battles at Antietam, Fredericksburg, Cold Harbor and Petersburg, and campaigns throughout Virginia. Drawing on soldiers' letters and diaries, this first-ever regimental history of the Eighth chronicles four years of combat service, with maps newly created from historical accounts.
