Regimental History
Ninetieth Infantry. Col., Timothy O'Meara; Lieut. -Cols., Timothy O'Meara, Smith McCleavy, Owen Stewart; Majs., Owen Stewart, Patrick Flynn. This regiment was mustered into the U. S. service at Chicago, Sept. 7, 1862. Co. A was recruited at Rockford, B at Galva, C at Lockport and LaSalle, D at Joliet, E at Chicago, F at Chicago and Springfield, G and H at Chicago, I at Belvidere and K at Ottawa. The regiment remained in Chicago until Nov. 27, performing guard duty at Camp Douglas, and then it was ordered to the front by way of Cairo. From there it proceeded by transports to Columbus, Ky., thence to La Grange, Tenn., where it arrived at 8 p. m., Dec. 2, and went into camp, naming its first village of tents in the South Camp Yates, in honor of the great war governor of Illinois. On the morning of Dec. 20, Gen. Van Dorn, after having surprised and captured Holly Springs, attacked the regiment at Coldwater, but the Confederates were repulsed. After the fall of Vicksburg the regiment took part in the Jackson campaign, which resulted in driving Johnston out of Jackson and across the Pearl river. Being transferred to eastern Tennessee, it participated in the battle of Missionary ridge, where the list of casualties in the regiment reached nearly 100. It participated in the Atlanta campaign, marching by way of Ship's gap, Villanow and through Snake Creek gap upon Resaca, where a lively battle was fought, the regiment sustaining a small loss in wounded. The next move was on Dallas, where a lively skirmish occurred, thence to New Hope Church, Big Shanty, Kennesaw mountain, Marietta, Nickajack creek, Rosswell and across the Chattahoochee river on July 9. At Atlanta on July 22 the regiment lost a considerable number of men captured, who were taken to Andersonville. In the assault on Fort McAllister near Savannah, the regiment lost 3 killed and 12 wounded. It then marched up through the Carolinas, and after the surrender continued the journey to Washington, where it took part in the grand review. On June 7, 1865, the regiment took its departure for Chicago.
