Hiram Gregory Berry
Hiram Gregory Berry was born in Rockland, Maine, in a district then known as Thomaston, on August 27, 1824. He was the son of a veteran of the War of 1812 and grandson of a soldier of the Revolution. In his early years he was a carpenter, contractor, bank president, Democratic member of the state legislature, mayor of Rockland, and captain of the local militia company. On June 15, 1861, he became colonel of the 4th Maine Volunteer Infantry, a regiment organized at Rockland for three-year service, and a month later accompanied it to First Manassas. His whole military service was with the Army of the Potomac, during which time he was advanced from colonel to major general of volunteers and extolled by his superiors. As a brigadier he commanded in the Peninsular campaign, where Philip Kearny, Joseph Hooker, S. P. Heintzelman, and George B. McClellan mentioned him in their official reports. He did not take part in the campaigns of Second Manassas and Sharpsburg because of illness, but returned to the army in time for the battle of Fredericksburg, where he commanded a brigade in the III Corps. Promoted to major general on November 29, 1862, Berry took Hooker's old division of the III Corps into the battle of Chancellorsville, under the command of General Daniel E. Sickles. In the confused fighting which occurred on the early morning of May 3, 1863, in the course of which the Federals attempted to regroup after Stonewall Jackson's celebrated flank march of the previous afternoon, Berry was killed at the head of his command. According to General Joseph B. Carr, his successor in command, Berry was mortally wounded at 7 A.M. and died within a half-hour. He was buried in Achorn Cemetery, Rockland.
