On October 1, 1862, the regiment moved to Frederick, Maryland, and a week later joined General George Meade's Division of Pennsylvania troops, above Sharpsburg, and near the battle ground of Antietam. With the exception of slight skirmishing, as the army moved south through Virginia, it had no experience in fighting until it entered upon the Fredericksburg campaign. After reaching Warrenton, where McClellan was replaced by Major General Ambrose Burnside, it passed through Fayetteville, Stafford Court House, Brooks' Station, and White Oak Church, encamping a short time at each place.
