The regiment went into camp at Iowa City, where it remained several weeks. On the 10th of November 1862, the regiment, numbering 956 rank and file, was mustered into the United States service. 2nd November it was ordered to move to the seat of war, and arrived at Helena, AR, on the 20th, where it encamped in tents for the first time. Here in addition to other disease engendered, owing to the swampy encampment, the small-pox broke out.

January 11, 1863, it formed a part of Gen. Gorman's expedition, which ascended the White River to Duvall's Bluff. During this expedition, the men suffered severely from storms and cold. Returning to Helena, rude Winter quarters were built and the sufferings of that Winter will never be fully told. In February, the regiment assisted in removing obstructions from Yazoo Pass. Col. Miller resigned in March, succeeded by Lt. Col. McConnell.

April 11th, the Twenty-eighth, which formed a part of the Second Brigade, Twelfth Division, Thirteenth Army Corps, started on the Vicksburg campaign, in which the regiment participated. It was first under fire at Port Gibson, May 1st, where it lost 1 man killed and 16 wounded, but the brave boys never flinched. At the battle of Jackson, on the 16th, the regiment fought like veterans. Of the Twenty-fourth and the Twenty-eighth, Gen. Hovey says, "Scarcely more than six months in the service, and yet no troops ever showed more bravery or fought with more valor." Here, the regiment lost 22 killed, 65 wounded, and 13 missing. Four companies came out without a commissioned officer.

On the day of the capitulation of Vicksburg, the regiment received orders to march with three days' rations. Death, wounds and sickness had so reduced the regiment that only 250 men were able to join in the march. Maj. Lynch had resigned and had been succeeded by Capt. John Meyer. It participated in operations before Jackson, and on the 25th of July, took up its line of march for Vicksburg, which place it reached on the 27th. Soon after, it was transferred to the Department of the Gulf, and 13 Sep 1863, moved into Western Louisiana, under Gen. Franklin. 1 Mar 1864, Col. Connell with his regiment arrived in New Orleans, and crossing the Mississippi went into camp at Algiers; and a few days afterward, moved to Alexandria, to join Bank's Red River expedition, in which it participated. At the battle of Sabine Cross Roads, the regiment lost 80 officers and men; Col. Connell was severely wounded and captured. 22 Jul 1864, the regiment embarked on the "Arago", bade farewell to Louisiana, and 2nd August landed at Alexandria, VA. Soon after its arrival it went into camp near Tenallytown, whence, after two weeks' rest it joined Sheridan's army in the Shenandoah Valley. Lost 90 men at Winchester where it was in the thickest of the fight. Was again engaged at Fisher's Hill, where it captured a battery of six guns, a large quantity of ammunition and many prisoners, with a loss of only 4 men wounded. It participated in the battle of Cedar Creek, in which it fought early and late, in the Fourth Brigade of Grover's Division.

January, 1865, it was ordered to Savannah, GA, where it performed garrison duty for several weeks. Re-enforced Gen. Schofield at Newbern, NC, where it was assigned to the Tenth Corps, and where it remained until Gen. Joe Johnston's surrender, when it was ordered back to Savannah, where on the last day of July 1865, it was mustered out of service; after which it proceeded to Davenport, Iowa where it was finally disbanded, in August.

It is to be said that among all the volunteer regiments which composed the Grand Army of the Union, not one did its duty better than the gallant Twenty-eighth Iowa Infantry.
