On June 24 it was moved to Bird's Point, Mo., where it remained, drilling, doing guard duty, working on fortifications, removing railroad buildings and track to keep the same from falling into the river, making new roads, etc., until Aug. 5, when it was moved into the swamp 8 miles west on the line of the Chicago & Fulton Railroad to guard it and protect workmen making repairs.

At Fort Donelson it occupied the right of Oglesby's brigade, on the right of the line of battle, and during the second day's fight lost 200 men in killed and wounded.

The regiment during the battle bravely and persistently maintained the position to which it was assigned in the early morning, and not until its ammunition was spent was the order to retire given.

Its place that eventful morning was one commanding the road from the fort by which the Confederates essayed to escape, which daring attempt, however, was most signally frustrated by Oglesby's dauntless brigade.

The regiment was with the Army of the Tennessee during the advance upon Corinth, serving in a brigade commanded by Col. Lawler, in McClernand's division.

On November 28, 1862, one-half the period for which the regiment was mustered into service having expired, a statement was made showing that the original strength of officers and men, with the addition of new recruits, aggregated 1,166, and the regiment had lost through all causes 456, leaving a total aggregate on the rolls of 710.

On December 20 the regiment, with other forces, was marched out towards Lexington and Trenton to intercept the Confederates in a raid then being made against Union troops guarding the railroads, etc., and on Dec. 31 Cos. E and H were engaged in a fight with the Confederates under Forrest near Lexington, driving the enemy with considerable loss.

On April 1, 1863, the regiment (250 mounted men) was moved toward Bolivar, Whiteville and beyond on the hunt of guerrillas and other Confederates said to be infesting the neighborhood, and a brush was had with a party posted in the road, the enemy being driven towards Danceyville, the regiment capturing some prisoners and horses.

On April 11 it was ordered to Summerville, Tenn., where it investigated the place and surrounding country, routing guerrillas and securing a few prisoners.

On August 31 the regiment was mustered and found to be so much reduced by sickness that less than 200 remained for duty, but on Sept. 11 those who were able advanced with the forces toward Little Rock, Ark., driving the enemy on both sides of the river and taking possession of the intrenchments and the city the same day.
