Mulligan, was made, June 15,1861, at Chicago, when it was occupying barracks known as Kane's brewery near the river on West Polk Street. It was early ordered to Northern Missouri, and was doing garrison duty at Lexington, when, in September, 1861, it surrendered with the rest of the garrison, to the forces under the rebel General Price, and was paroled.

Thereafter it participated in engagements in the Virginias, as follows: at South Fork, Greenland Gap, Philippi, Hedgeville, Leetown, Maryland Heights, Snicker's Gap, Kernstown, Cedar Creek, Winchester, Charlestown, Berryville, Opequan Creek, Fisher's Hill, Harrisonburg, Hatcher's Run and Petersburg. It also took part in the siege of Richmond and the pursuit of Lee, being present at the surrender at Appomattox.
