Before the Antietam Campaign:
"The Rev. John B. Clark, at that time pastor of the Second United Presbyterian Church, in Allegheny [PA], and a clergyman of nearly eleven years' standing, at the close of his services on Sabbath, the 5th of August [1862], requested those of his congregation who were willing to enlist in the national armies, to meet him in the basement of the church on the following Monday evening. Many came, and in three days' time three companies were organized, of one of which, Mr. Clark was elected Captain."1

By the end of August the 123rd Regiment had been organized for 6-months' service, and Clark was appointed Colonel.

In the Antietam Campaign:
He and the 123rd arrived at the battlefield of Antietam on the morning of 18 September, after a forced march from Frederick which began on the afternoon of the 17th.

The remainder of the War:
He led the regiment in a charge on Marye's Heights at Fredericksburg in December. He and the Regiment mustered out at the expiration of their 9-month term of service on 13 May 1863, at Harrisburg, PA.

After the War:
He returned to Allegheny and his congregation, and was on the Presbyterian board of missions to the freedmen of the South (July 1863-64).
