The regiment left Monroe March 27th and arrived at Pittsburg Land­ing, Tenn., Just in time to participate in the battle fought there on the 6th and 7th of April, when the Union forces were commanded by General Grant and the confederates by Albert Sidney Johnson.

It was attached to General Rosseau’s brigade during the engagements and suffered a loss of 2 officers and 31 men killed, 1 officer and 63 men wounded. It was a severe experience for troops but recently organized, but the regiment fought with the steadiness of veterans and received a most complimentary notice in orders from the brigade commander for con­spicuous gallantry.

The Fifteenth took part in the siege of Corinth, Miss., which lasted from May 10th to the 31st, and met the enemy at Iuka, Sept. 19, Chewalla, Oct. 1, and on the 3d and 4th was in the advance at Corinth, when an attack was made by the enemy, resulting in a loss to the Fifteenth of 13 killed and 32 wounded.

In November the regiment moved to Grand Junction and remained in the vicinity until June, 1863, when it was attached to the First Division, Sixteenth Corps, and in command of Colonel Oliver was ordered to Vicksburg, Miss. It proceeded to Hayne’s Bluff, where it was temporarily at­tached to the Ninth Corps, and on July 6th crossed the Big Black in the advance upon Jackson, and operated with the Ninth Corps until the con­federates were driven across Pearl River, July 17th. Vicksburg having surrendered, the Fifteenth was attached to the Second Brigade, Fourth Division, Fifteenth Corps, and moved with its corps to reinforce the Army of the Cumberland. Passing through Memphis, Tenn., Corinth, Miss., it arrived at Florence, Ala., Nov. 1st.

The regiment then moved to Bridgeport, Ala., and then to Scottsboro, where it remained until February, 1864. At this place 186 members re- enlisted and the regiment returned to Monroe, where the men were given a veteran furlough to vifcit their homes.

The regiment assembled again at Monroe and proceeded to Chattanooga, Tenn., where it arrived May 4th. It engaged immediately in the Georgia campaign with General Sherman’s army and was constantly marching and fighting, participating in many of the hard-fought battles before crossing the Chattahooche River, and then went into the intrenchments during the siege of Atlanta.

At Decatur, a few miles east of Atlanta, on the 22d of July, the Fif­teenth had a desperate engagement with General Hood’s army, but fought with such gallantry that it captured the colors of two confederate regiments and 176 prisoners, and succeeded in repulsing a very determined attack of the enemy. It was constantly under fire during the siege, and when ₍General Sherman moved his army to the south of Atlanta the Fifteenth re­pulsed a heavy assault at Jonesboro, the battle that caused General Hood to evacuate Atlanta.

The regiment then went into camp at East Point, Ga., for a long needed rest, but when General Hood started north with his army the Fif­teenth joined in pursuit. It started October 4th and marched by way of Marietta, Allatoona, Rome, Resaca, Snake Creek Gap, Ga., to Carr Springs, Ala., and the records show the regiment marched 200 miles during the month and participated in numerous skirmishes, some of them arising to the dignity of battles.

Leaving Hood to pursue his march north upon Nashville, where Gen­eral Thomas was in readiness to receive him. the Fifteenth returned to Atlanta, where it arrived on the 12th, and two days afterward commenced the march from Atlanta to the sea.

It was then serving in the Third Brigade, Second Division, Fifteenth Corps. The regiment moved with the corps upon Savannah, and after the surrender of that city remained in camp until January 14, 1865, when it em­barked upon transports for Beaufort, S. C.

On the 30th it commenced the march through the Carolinas, via Orangeburg, Columbia, Cheraw and Fayetteville, reaching Goldsboro March 14th.

Colonel Oliver was promoted to Brigadier General January 12. 1865, and Frederick S. Hutchinson was commissioned Colonel January 14, 1865. and under his command the regiment marched to Raleigh, N. C., and then to Washington, D. C., where it arrived on the 21st and took part in the grand review with Sherman’s army May 24th.

June 1st the regiment was sent to Louisville, Ky., and then to Little Rock, Ark., where it arrived July 7th. It remained here until August 21st, when it started upon its return to Michigan, and arrived at Detroit Sep­tember 1, 1865, where it was paid and disbanded.
