A 117th regt N.Y.V. / Fort Franklin / Sept. 27th 1862." Isaac H. Dann enlisted on 8 August 1862 at Rome, NY as a 2nd lieutenant and was commissioned into Company A.

Henry Dawson enlisted on 9 September 1862 in Brooklyn, NY as a private into Company C of the 139th New York and was discharged on 8 November 1863.

He was wounded again at Petersburg, VA on 2 April 1865 and died of his wounds 5 days later at City Point, VA hospital.
