"Among the many heroic regiments at the battle of Chancellorsville, none suffered more severely or fought more heroically, than the One Hundred and Fifth Pennsylvania Volunteers, raised in part through the energy and trained by the skill of Colonel Arthur [sic] A. McKnight. It was, with its heroic leader, ever found ready for any needed post of danger. Colonel McKnight was early cast upon his own exertions by the death of his father. As a son and brother he ministered tenderly to those dependent upon him.

"In 1861 he raised a company of three-months men, in Brookville, in his native State, and after their discharge he interested himself deeply in the One Hundred and Fifth Pennsylvania, and was chosen colonel of the regiment. His discipline was strict, perhaps a little stern; but when in battle or review, his soldiers bore testimony by their conduct to the faithful instructions of their commanding officer. Fair Oaks, Fredericksburg, and Chancellorsville witnessed their gallantry. At the latter place, Colonel McKnight, while leading his troops, was struck in the arm by a ball, which, passing through it, entered his head, near the left eye, and he was instantly killed. His heart was for his whole country. He was ready to suffer, to fight, to die for it, and he fell a noble sacrifice upon its altar."
