He was 21 years old when he was enlisted (12, 21 [38 in 1880]). He was born in Pennsylvania (21).
He was living in Philadelphia, Pennsylvania, when he was enlisted (12).
He was enlisted and mustered into service on 7 October 1861 (1, 9, 11, 12, 18). He was enlisted at Philadelphia, Pennsylvania (12). He was mustered in as a first lieutenant, at Philadelphia, Pennsylvania, by Captain Dye (11, 12). He served as a first lieutenant in company D (1). On an undated recruiting poster, he is listed as company D's first lieutenant (13).
On 29 June 1862, he, along with the other commissioned officers in the regiment (except Colonel Gregory), signed a statement denying accusations that they were on the verge of open mutiny, that the regiment had been reduced to 400 men, and that Colonel Gregory was too lenient to Confederates and too harsh to men in the regiment (17).
Brigadier General Tyler detailed him as aide-de-camp on 4 November 1862 (4, 5, 6). He was still detailed there on 7 February 1863 (10), 28 August 1863 (4), 14 November 1863 (5), and 7 March 1864 (6).
While serving as Brigadier General Tyler's Aide during the Battle of Fredericksburg, he conveyed to Colonel Gregory (commanding the 91st PA) and to Lieutenant-Colonel Rowe (commanding the 126th PA) orders to retreat across the river. When Colonel Gregory did not want to leave until his detached company E returned, he assured Colonel Gregory that the order had been conveyed to Captain Lentz. Unfortunately, he was wrong.(22)
He was commissioned captain on 16 December 1863, but he refused the commission (12).
On 4 July 1864, he was the only commissioned officer in company D, which had 37 enlisted men present for duty, and a total of 74 enlisted men (7).
He was discharged on 24 July 1864 on surgeon's certificate of disability, by special order 186, War Department, 25 July 1864 (1, 2 [resigned], 7 [25 Jul], 9 [25 Jul], 12 [24 Jul], 15 [25 Jul]). He was still aide-de-camp to Brigadier General Tyler when he resigned (8).
He was an original member of the Military Order of the Loyal Legion of the United States (16).
In 1880, he was living on 1735 Lambert Street, Philadelphia, Pennsylvania (21). He was a clerk (21). He was living with his wife Mary, and his daughters Geneve and Mabel (21).
On 13 November 1886 [?], he applied successfully from Washington DC for a pension (14).
