The Fifteenth Infantry was organized September, 1862, with Maxwell McCaslin, colonel; Thomas Morris, lieutenant colonel; the latter having won his advancement by meritorious conduct as captain in the Seventh West Virginia Infantry. Milton Wells, was commissioned major by Governor Peirpont, October 16, 1862. Major Wells assisted in recruiting this regiment, and like Lieutenant-Colonel Morris, had seen hard service; first as a private of Company D, 27th Ohio Infantry; later was commissioned captain of the same company, serving as such with his regiment in Missouri until August, 1862, when he resigned to accept promotion in the 15th W. Va. Infantry, rendering special service as drill master. This regiment took an active and gallant part in all the battles of the Shenandoah Valley, from the time of its organization until the last battle of Cedar Creek.

At the battle of Snicker’s Ferry, Va., July 18, 1864, Lieutenant-Colonel Morris was killed, and on August 8, 1864, Major Wells was promoted to lieutenant-colonel. On September 7, 1864, Colonel, McCaslin resigned his commission, when Lieutenant-Colonel Wells succeeded to the colonelcy, and was in command of his regiment at the battle of Cedar Creek, October 19, 1864, and he was the first to discover the Confederate forces advancing on that notable morning, and ordered the firing of the first musketry in that engagement. As a result, his command was the only one in that engagement that left dead and wounded soldiers on the parapets. In this engagement, Colonel Wells lost all of his personal baggage, equipment, etc., but in the rally of the afternoon recaptured them, among which was his commission as colonel. It was found in the pocket of a prisoner, covered with mud and dirt, and in that condition it remains at this date, hung in a frame at the colonel’s residence in Iowa. During the engagement of the afternoon of this day, Colonel Wells was wounded in the left hip, from which he endures much suffering at the present time. This regiment served mostly in the Eighth Army Corps in West Virginia, in Colonel Thoburn’s brigade and division. In the spring of 1864, the brigade in which the 15th W. Va. was attached was transferred to the Army of the Potomac. On this march, Colonel Wells caught cold in his wound, when sciatica was produced and great suffering followed. On April 16, 1864, Colonel Wells was honorably discharged, because of disability produced by this wound.

This regiment served with distinction in the Army of the Potomac, in the 24th Corps, First Brigade, under the command of Brev. Maj.-Gen’l Thomas M. Harris, formerly colonel of the 10th W. Va. Infantry. The regiment was mustered out of the service at Richmond, Va., June 14, 1865.
