 Harrison C. Hobart, Captain in the Fourth Wisconsin Infantry, had been commissioned Lieutenant Colonel, but being, at the time, on duty at Now Orleans, did not join the regiment at the time of its organization. The regiment left the State on the 11th of September, 1862, for Cincinnati. Arriving there, they crossed the river to Covington, where they received their arms, and were immediately assigned to duty in the trenches, where they suffered severely for the want of tents and camp equipage. From this point they marched to the defense of Louisville, under Brigadier General P. H. Sheridan. Here the regiment first received their tents, and became equipped for the field, and was assigned to the Twenty-eighth Brigade, in the division commanded  General Rousseau, and marched, with the Army of the Ohio, into the interior of Kentucky, and on the 8th of October, was engaged in the battle of Perryville. In this battle, Colonel Sweet was in command. The regiment was placed, erroneously about a hundred yards in front of the left of the main line, in a position between the two armies, and in consequence, suffered from the fire of both lines. From this position, the regiment was quickly driven back to the rear of our line, with severe loss. Major Frederick Schumacher, Captain Hiram Gibbs, Captain George Bentley, and Second Lieutenant David W. Mitchell, of Company C,, were killed, and Colonel B. J. Sweet, First Lieutenant A. B. Smith, Company I, and First Lieutenant F. Ostenfuldt, Company E were wounded, and Second Lieutenant C. H.

Colonel Sweet being disabled by a ball which he received after the regiment had fallen back, did not again assume command. Lieutenant Colonel Harrison C. Hobart, joined the regiment at. Lebanon, Ky. Having left their camp and garrison equipage at Louisville, the men suffered severely from exposure. Leaving Lebanon, October 29th, the regiment arrived at Bowling Green, November 4th, Surgeon Caroline died at this place. On the 10th of November, they marched to Mitchelville, a station on the railroad. Here the Twenty-first was engaged in guarding the road and the supplies of the army. The men suffered greatly from hardships, being exposed to severe weather without shelter. Captain Jewett, of Company D. and several others, died at this place. December 7th, the regiment marched toward Nashville and went into camp five miles South of that city December 9th and remained there until the morning of December 26th. The army under Major General Rosecrans, moved upon the rebel army then lying at Murfreesboro, Tenn. The Twenty-first then belonged to the Third Brigade, First Division, Fourteenth Army Corps of the Army of the Cumberland. On the 30th of December, the army met the enemy near Stone River, and the third Brigade, on the extreme left, was detached from the main line to cover what is known as the Jefferson Pike. The brigade train was attacked here on the morning of December 30th, by Wheeler's rebel cavalry of thirty-five hundred men, while it was moving on the road. The Twenty-first was nearest the point of attack. It rapidly moved to the rear of the flying train, and forming a line of battle near a blockhouse, fought the enemy until they were routed. The loss of the enemy in this engagement was over eighty, killed and wounded. The next morning the regiment moved to its position in the line of battle of the Fourteenth Corps, and was actively engaged at the front throughout the battle of Stone River. Brigadier General Rousseau, in his report of this battle, mentioned the Twenty-first Regiment, and its commander, Lieutenant Colonel H. C. Hobart, for good conduct. The loss in this engagement was not severe. Benjamin D. Tuney, Company D, died of wounds, and Lieutenant A. B. Smith, of Company I, was wounded. On the 5th of January 1863, our army entered Murfreesboro, and the Twenty-first went into camp near that city. From January 5th, until June 24th , the Twenty-first lay at Murfreesboro, foraging, drilling, fortifying, and skirmishing with the enemy. The regiment then moved with the army upon the enemy who were encamped near Tullahoma.. On the 26th of June, the Twenty-first was engaged in driving the rebels from a strong position at Hoover's Gap, and afterwards followed the retreating enemy to the Tennessee River.
September 1st, the Tennessee River was crossed at Bridgeport, Ala. The Twenty-first was with the army in crossing the two ranges of steep mountains below Chattanooga, and joined in the march to Dug Gap, where the enemy was found in great force. The Union forces were withdrawn from this dangerous position with great difficulty, the Twenty-first forming the rear guard. The rebel army, reinforced by Longstreet had assumed the offensive. On the 19th of September, the Third Brigade of the First Division, to which the Twenty-first belonged was moved to a position near one of the gaps at Mission Ridge, and in front of one of the fords of the Chickamauga. A large rebel force commenced crossing this ford early in the morning. Early in the day commenced the terrible battle of Chickamauga. The Twenty-first, under the command of Lieutenant Colonel Hobart, with the rest of the Third Brigade, commanded by General Starkweather, were moved into the line of battle, and during a Severe engagement in the forenoon, held its position until the other regiments of the brigade were driven to the rear of them. At this moment, the Fourth Indiana Battery was captured by the rebels, and was retaken immediately by a part of the Twenty-first, and other troops. Heavy firing continued till late in the evening, and the Twenty-first was under arms at the front until 12 o'clock at night. On the morning of the 20th, the regiment with its brigade, was early placed in line of battle; it was a part of the ever memorable line of the Fourteenth Corps under Major General Thomas. The Division was commanded by Brigade General Baird. At about 9 o'clock, A. M., the rebel forces commenced a series. of terrible charges, which were repeated until the close of that eventful day. The First Division occupied the extreme left of the line, the Twenty-first being on the right of the Division, with a heavy battery in position at each flank. That part of the line in which the Twenty-first was stationed, never faltered during the day, although the trees on the line were nearly all cut down by the fire of the enemy's batteries. Near sundown, General Thomas ordered a retreat, the right wing having been flanked by the enemy. The Twenty-first did not receive the order, and held their line fighting until they saw the other regiments suddenly moving to the rear. Lieutenant Colonel Hobart then ordered the regiment to fall back to the second line of works, where, still fighting, they remained until nearly surrounded by the enemy. The regiment then attempted to cut its way to the rear, in which attempt Lieutenant Colonel Hobart, with about seventy officers and men, were captured. The flag of the Twenty-first, the last of the Fourteenth Corps, and its gallant Sergeant, remained in front until captured by the enemy

After this battle, the regiment, with what remained of the brigade, was retired to a of defense Bear Mission Ridge, and September 22d, it fell back to Chattanooga, where it remained with the shattered remnant of Rosecrans' army in the defense of that place. During the winter of 1863-4, it held the outpost upon Lookout Mountain, and remained in this position until the 2d of May, 1864. Colonel H. C.  Hobart having escape from Libby Prison, after more than four months' close confinement, returned to the regiment at this place. The health and discipline of the regiment was greatly improved at this post.
 On the morning of the 2d of May, 1864, the regiment, 400 strong, in splendid condition, marched from the mountain to join in the advance upon Atlanta. Here the Twenty-first was transferred to the First Brigade of the First Division, Fourteenth Army Corps. The brigade was commanded by Brigadier General Carlin. The campaign opened at Rocky Face Ridge, near Dalton, on the 8th of May, where the enemy were strongly posted The Twenty-first were in the flank movement made by General Sherman, through a gap called Snake Creek, which caused the enemy to fall back to Resaca. On the 14th of May, the First Brigade, with the Twenty-first in the front line, was ordered to assault the enemy's works. This terrible and bloody assault was made in the early part of the day, and although not  the brigade held its position near the enemy's line until after dark, the Twenty-first being the last regiment to retire.

On the 4th of November, the army passed through Marietta, leaving the beautiful town in flames, and on the 15th, entered burning Atlanta. The regiment, well equipped and clothed, and with haversacks filled for the last time from the stores of the army, moved forward on that wild, bold and romantic march with no hospital, without a base, and with rations and forage only for a few days. November 17th, the regiment reached the Oconee River. Regular foraging parties were organized, to, obtain supplies for the men and animals. November 23d, the Twenty-first entered Milledgeville, thus far meeting no enemy except occasional scouts of rebel cavalry. Much of the time was employed in destroying railroads and bridges.

Lieutenant Colonel Fitch being detailed to the command of three regiments, Major Walker assumed command of the regiment. The Twenty-first, crossing the Savannah River with the Fourteenth Corps, shared actively in the campaign which  "marked the earth with ruin." The regiment marched with the column that passed north of Columbia, and after overcoming almost insurmountable difficulties, crossed the Catawba River. The roads were almost impassable, and the men will never forget the many miles of corduroy which they constructed. March 4th 1865, the Twenty-first entered North Carolina. At this point the burning ceased. March 11th, the regiment encamped at Fayetteville, on Cape Fear River. Leaving  Fayetteville, it was in the advance brigade, which encountered the enemy, in force, on the 19th of March, near Bentonville.
