Before Antietam

After graduating from West Point he was breveted 2nd Lieutenant in the 3rd United States Artillery on 1 July 1848. He was commissioned 2nd Lieutenant in the 4th US Artillery on 6 January 1849, was promoted to First Lieutenant on 11 December 1850, and to Captain on 14 May 1861, having served on garrison duty all over the country and as Mathematics instructor at West Point. He first saw combat at Winchester, in the Shenandoah Valley of Virginia, in March 1862.

On the Campaign

He commanded his battery on the Maryland Campaign. Brigade commander Nagle, in his after-action report noted:

"... I cannot refrain, however, from speaking of Captain Clark, of Battery E, Fourth Artillery, who did excellent service, and received four wounds during the day [at Antietam]."
Clark was wounded in three places in the leg and one in the hand by shrapnel from an exploding artillery shell.

The rest of the War

After at least 8 months of recovery he was found medically unfit for field service and was detailed as an assistant professor of Natural and Experimental Philosophy at West Point in August 1863. He retired from the Regular Army on 11 May 1864 with rank of Major (to date from 28 July 1866), but remained as an instructor at the Academy. He was honored by brevets to Major and Lieutenant Colonel, USA, respectively, for his actions in the Shenandoah Valley and at Antietam.

After the War

He was at West Point until 1870, then taught military science at the University of Pennsylvania in Philadelphia from 1874-75. From 1876 to 1878 he was Deputy Governor of the Soldiers' Home in Washington, DC. He was author of A Manual of Heavy Artillery Service (1880) - a West Point textbook.
