The 78th Illinois Infantry Regiment Regiment was organized at Quincy, Illinois, in Adams County. The 78th Illinois Infantry Regiment, would see all of its wartime duty in the Western Theater of the American Civil War.

The 78th Illinois was originally attached to 39th Brigade, 12th Division, Army of the Ohio. The regiment went through a series of reassignments; first in November 1862 to Gilbert's Command, District of Western Kentucky, Department of the Ohio. While in Franklin, Tennessee, in February 1863 the regiment was assigned to the Army of Kentucky, Department of the Cumberland. In June 1863, another reassignment assigned the 78th Illinois to the 2nd Brigade, 1st Division Reserve Corps, Army of the Cumberland. The final reorganization would come in October 1863, assigning the regiment to the 2nd Brigade, 2nd Division, XIV Corps.

The regiment received the blue United States uniform, typical of the civil war. Initially, the regiment was armed with .69 caliber rifled muskets, altered to use a percussion cap. In 1863, the regiment saw more modern arms provisioned to the soldiers; a mixture of the Enfield rifle and Springfield Rifle Muskets were carried. In 1864, all troops were armed with the Springfield Rifle Muskets.
