Before Antietam

In 1860 he was a farmer at Simsbury in Hartford County, CT. He enlisted and mustered as First Sergeant of Company E, 16th Connecticut Infantry on 7 August 1862.

On the Campaign

He was with his Company in action at Antietam on 17 September 1862.

The rest of the War

He was promoted to First Lieutenant, probably in December 1862, and was captured, along with most of his regiment, at Plymouth, NC on 20 April 1864. He was a prisoner in Macon, Savannah, and Andersonville, GA, and Charleston and Columbia, SC. He was paroled in March 1865 and was discharged on 15 May 1865.

After the War

By 1870 he was a farmer on his father-in-law's place at Simsbury. In 1880 he was working his own place at Simsbury (and his widowed mother-in-law was living with him); he was there to at least 1900, by then living as an "invalid soldier."
