[1] The regiment served under generals Grant and Sherman and was engaged in the battles Stone's River, Chickamauga, Franklin, Nashville, Missionary Ridge and Chattanooga.

By the end of the war, MacArthur had risen to second in command of the regiment with the rank of colonel at the age of only 19.

On September 5, 1912, Lieutenant General Arthur MacArthur died while addressing his old unit.

MacArthur also coined the Wisconsin state slogan when he cried "On Wisconsin" as he led his men up Missionary Ridge at the battle of Chattanooga, a feat for which he would later receive the Medal of Honor.

The 24th Wisconsin suffered 8 officers and 103 enlisted men killed in action or who later died of their wounds, plus another 3 officers and 87 enlisted men who died of disease, for a total of 201 fatalities.
