Regimental History
One Hundredth Infantry. — Cols., John C. Groom, Patrick S. Slevin, Edwin S. Hayes; Lieut.-Col., Frank Rundell; Maj., John A. Shannon. This regiment was organized at Camp Toledo, in July, Aug., and Sept., 1862, to serve for three years. It first moved to Cincinnati for the defense of that city and went into position on Covington heights, a few rods in front and to the left of Fort Mitchel. It remained in Kentucky for nearly a year, going wherever the presence of the enemy rendered it necessary, and then was sent to East Tennessee, where it participated in the defense of Knoxville. In the spring of 1864 it moved on the Atlanta campaign and was present at almost every battle from Rocky Face ridge to Atlanta. On Aug. 6 it was engaged in an assault on the Confederate works in front of Atlanta, with a loss of 103 men out of 300. Thirty-six men were killed on the field and 8 more died from wounds within the next 30 days. After the evacuation of Atlanta it joined in the pursuit of Hood and participated in the battles of Franklin and Nashville. It then moved to North Carolina, was there actively engaged, and thence home, where it was mustered out on June 20, 1865. It lost during its term of service 65 men killed in action, 142 wounded, 27 died of wounds, 108 of disease, 325 were captured by the enemy, of whom 85 died in Confederate prisons.Footnotes:
