The 5th Wisconsin Infantry Regiment was an infantry regiment that served in the Union Army during the American Civil War.
The 5th Infantry was assembled at Camp Randall, in Madison, Wisconsin, on July 12, 1861. It left Wisconsin for Washington, D.C., on July 24, 1861. During the war it moved through Virginia, Maryland, Pennsylvania, and New York (helping to quell that city’s famous draft riots). It participated in the battles of Williamsburg, Antietam, Fredericksburg, Gettysburg, the Battles of the Wilderness, and the surrender of Gen. Robert E. Lee and his army.
The non-veterans were ordered home to Wisconsin on July 16, 1864, and mustered out of service on August 3. The veterans were consolidated to a battalion of three companies who continued to serve until June 24, 1865; the remainder of the regiment was mustered out of service on July 11, 1865.
