123rd Regiment, Pennsylvania Infantry

Historical Sketch:
Col., John B. Clark ; Lieut.-Cols., Frederick Gast, Richard C. Dale; Majs., Hugh Danver, Charles D. Wiley. This was a nine months' regiment, recruited mainly in Alleghany county, and mustered into the U. S. service in Aug., 1862. It left Harrisburg on Aug. 21 for Washington and was at once ordered to Camp Stanton, where it was attached to the 2nd brigade, 3d division, 5th corps. During the battle of Bull Run it was posted at Bailey's cross-roads to prevent stragglers from passing, but was soon returned with the other troops to Washington. Late on the afternoon of Sept. 17 it was sent to Antietam, but was too late to participate in the battle which was not continued as expected on the next day. The regiment then proceeded to Warrenton with the army and encamped at Potomac creek, near Fredericksburg, until Dec. 12. On the afternoon of the next day it was ordered into action and charged the heights, but unsuccessfully as had the previous divisions, the loss of the regiment being 152 killed and wounded. Returning to the former camp, it remained there until Jan., 1863, when it moved to Falmouth, and on April 28, started for Chancellorsville, where on May 1, it was posted on the left of the line, which was not engaged. On the 3d it was placed in support of the artillery and met with a few losses. The 123d was mustered out of the service at Harrisburg on May 13, 1865. Roster:
