Willard R. Moulton was a resident of Mansfield on April 25, 1861 when he enlisted as a Corporal in Co. D of the 3^rd Regiment Connecticut Volunteer Infantry; he was captured July 21, 1861 at the First Battle of Bull Run, Virginia, paroled June 2, 1862 and discharged July 6, 1862. 

He was born about 1842 in Mansfield probably to Harvey and Anna (Turner) Moulton. In the 1850 U.S. census in Mansfield, he is believed to be the Rufus W. Moulton, 19 in the household of Anna Moulton; he was a factory laborer. It is possible that he was the Willard R. Moulton who enlisted as a 1^st Sergeant in Co. K of the 4^th New York Regiment Volunteer Cavalry on October 30, 1862. That soldier was transferred to Co. D of the 20^th Regiment Veteran Reserve Corp on May 19, 1864. 

The Mansfield death record does not list a place of death and stated that he was 33 and was married; the name of his wife was not provided and no pension record has been located for him.

Willard R. Moulton died of consumption on April 2, 1865 and is buried at the Gurleyville Cemetery in Mansfield.
