The 191st Regiment was organized at Camp Chase, Ohio, and mustered into the service March 10th, 1865, under Colonel Robert B. Kimberly, who had served as Lieutenant Colonel of the 41st O. V. I.; Lieut. Col. Edward M. Driscoll, who had served as a Captain in the Third Ohio Infantry, and Maj. Nathaniel J. Manning, who had served as a Captain in the 25th O. V. I.   It was very fortunate that the regiment was organized under these veteran officers, and it was soon equipped and ready for the field.
     On the day of organization, the regiment was ordered to Winchester, Va., and reported to General Hancock, who was in command of the First Army Corps, but was intercepted by an order to stop at Harper's Ferry, and was assigned to a brigade composed of the 192nd O. V. I., 193rd O. V. I. and 196th O. V. I., thus forming an Ohio brigade.

     Colonel Kimberly having been promoted to Brigadier General, was assigned to command the brigade.  Soon after the organization of the corps, the designation was made Second Brigade, Second Division, Army of the Shenandoah.  Strict discipline was inaugurated by Colonel Kimberly in the regiments composing the brigade, and a great deal of time was devoted to drill and practice marching.  The brigade was reviewed by General Hancock during the month of May, and was very highly complimented for their soldierly appearance while marching in review.
     The regiment served on garrison duty in the Shenandoah Valley during the summer, and during a part of its service was stationed at Winchester.  The regiment was kept on duty continuously until the latter part of August, and was the last regiment retained in the Shenandoah.
     The losses by death were twenty-nine.  Two Jerome Township soldiers served in this regiment, Lieut. Henry Hensel and David B. Lattimer.  The regiment was mustered out at Camp Chase. Ohio, September 3rd, 1865.
