Regimental History
One Hundred and Twentieth Infantry. — Cols., Daniel French, Marcus M. Spiegel; Lieut.-Cols., John W. Beekman, Williard Slocum; Maj., John F. McKinley. This regiment was organized at Mansfield from Oct. 7 to 17, 1862, to serve for three years, and was consolidated with the 114th Ohio infantry on Nov. 27, 1864. The regiment was mustered into the U. S. service with an aggregate of 949 men and its first service was performed in Kentucky. It remained in that state until ordered south preparatory for the Vicksburg campaign. The regiment was ordered to cover a working party engaged in laying a pontoon across Chickasaw bayou, and hence took no part in the assault on the bluffs, but it was exposed to the enemy's fire during the entire day. In the movement against Arkansas Post the regiment was in position on the extreme left of the line and charged directly upon the fort. In the battle of Port Gibson the loss of the regiment was 1 for every 8 it had engaged. It remained at Vicksburg as part of the besieging force until May 24, when it was ordered to the Big Black river to guard against an approach of Confederate forces under Gen. Joe Johnston and remained there until after the fall of Vicksburg. It was actively engaged in the attack on Jackson from the day the investment began until the enemy evacuated the place and retreated across the Pearl river. In August the regiment was ordered to Louisiana and remained there until the following May, when, while on the transport "City Belle," on Red river, near Snaggy point, it was attacked by a large force of Confederates and compelled to surrender, only a few of the men escaping. The following November the regiment went out of existence by consolidation and up to that time the aggregate losses numbered 600 men.Footnotes:
