Selden’s foray into the military began while residing in Jamestown when he began serving as quartermaster of the Sixty-eighth Regiment, National Guard. On July 21, 1862, he would tender his services to the U.S. government and was commissioned adjutant of the 112th New York Volunteer Infantry. Selden would serve in that role until detailed as assistant adjutant-general of Foster’s Brigade with the Army of Southern Virginia. He would serve through the Peninsula and Charlestown campaigns, until August 27,1863, when he was appointed additional paymaster of United States volunteers, and was assigned to duty in the army of the Potomac. Selden would resign on December 27, 1864, to become paymaster general of the state of New York on the staff of Governor Fenton.
