From the hill behind this monument on the morning of July 3, the Second Mass. Inf. made an assault upon the Confederate troops in the works at the base of Culps Hill opposite. The regiment carried to the charge 22 officers and 294 enlisted men. It lost 4 officers and 41 enlisted men killed and mortally wounded and 8 officers and 84 enlisted men wounded.
