The 42nd Wisconsin Infantry Regiment organized at Camp Randall in Madison, Wisconsin, with the last company mustered into service on September 7, 1864. The regiment left the state on September 20 and proceeded directly to Cairo, Illinois, where they stationed for post and garrison duty.
On October 25, Companies B, E, G, H, and K were ordered to Springfield, Illinois, for provost duty. This battalion remained there until April 1865, when all except Company B reassembled at Cairo and was engaged in garrison and guard duty until the regiment was ordered to return to Wisconsin.
The regiment reached Madison on June 20, 1865, and was shortly thereafter mustered out and disbanded.
The regiment lost 58 men to disease.
