Home State: Pennsylvania
Branch of Service: Infantry
He mustered into service as Private, Company G, 107th Pennsylvania Infantry on 11 February 1862.
On the Campaign
He was with his Company at Turner's Gap and was posted as sentry near midnight on 14 September. He came face-to-face with Lieutenant W.P. DuBose of the Holcombe Legion, who had been sent to see if the Federals were still there. Dubose pulled his pistol, which discharged. Startled, but probably not hurt, Cronin knocked Dubose to the ground and helped capture him.
The rest of the War
He was wounded in action at Fredericksburg, VA on 13 December 1862. He mustered out with his Company on 11 February 1865.
After the War
He applied for a pension in 1882 and DuBose validated his story of the capture on South Mountain to the Pension Board. He met DuBose for the second time in Sewanee, TN about 1897.
