This regiment, known as the 1st Irish regiment, was organized at Indianapolis and was mustered in December 11, 1861. It left the state December 13, for Bardstown, Kentucky, and six weeks later joined Buell’s army at Bowling Green, moving thence to Nashville, where it was joined by the organized portion of the 61st (2nd Irish) regiment and the unassigned recruits of the same, the latter being consolidated with the 35th.

Colonel B. F. Mullen, who had them in charge was made lieutenant-colonel of the 35th in place of Lieutenant Colonel Ryan (who had left the service in February), and then later Colonel, when Colonel Walker left, August 6, 1862.  The regiment moved to McMinnville, Tennessee, and later to Louisville as part of Matthews’ brigade, Van Cleve’s division, Crittenden’s corps.

It was in the pursuit of Bragg, participating at Perryville and in numerous skirmishes.  It was then inactive at Nashville until December, when it was in a severe skirmish at Dobbins’ ford near Lavergne, while on a foraging expedition.  It participated in the battle of Stone’s River, losing 29 killed, 72 wounded and 33 missing.

It remained in the vicinity of Murfreesboro until the march for Chattanooga commenced, and was in the battle of Chickamauga, with heavy losses.  It encamped at Shell Mound, where it reenlisted on December 16 as a veteran organization and
on returning from a furlough home in February it went into camp at Blue Springs, Tennessee.

It was assigned to the 2nd brigade, 1st division, 4th corps, and took part in the Atlanta campaign.  At Kennesaw mountain it was in the front line and received a fierce and unexpected attack, but rallied from a momentary confusion and fought
hand-to-hand with clubbed muskets and bayonets until finally, with the assistance of another regiment, the enemy was driven back.  The 35th lost 11 killed, including Maj. Dufficy and 54 wounded.

At Marietta it advanced on the skirmish line, captured the enemy’s rifle pits and 28 prisoners, although two other regiments were repulsed.  Being greatly reduced in numbers, it was assigned to train-guard duty until August 31. It  participated in the engagement at Jonesboro, entered Atlanta September 9, and later marched in pursuit of Hood’s forces into Tennessee.

Reinforced by 400 drafted men and substitutes, it was placed in the front line at Franklin and repulsed a charge on the works.  It took a conspicuous part at the battle of Nashville, and participated in pursuit of the enemy as far as Duck River,
at which point it was detached and assigned to the charge of the pontoon train.

It next moved to Huntsville and Knoxville, but returned to Nashville in the spring of 1865, when it was ordered to Texas, and remained there until mustered out September 30, 1865.  Its original strength was 871; gain by recruits, 806;
reenlistment’s, 192; total, 1,869, Loss by death, 244; desertion, 269; unaccounted for, 51.
