- Note: The 12th Connecticut arrived at Bermuda Hundred on July 19, 1864. A history of the regiment in Record of Service of Connecticut Men in the Army and Navy of the United States During the War of the Rebellion indicates the regiment only stayed at Bermuda Hundred for two days, but it seems more likely the unit was there with the rest of its brigade until July 27 or 28, 1864. More research s needed.10,11
