"Well, a little past 10 years old, I, with my father and friends, on the 9th of August [1862] entered Camp Dennison; and how proud I felt with my little drum on my back a-going in the army as a drummer boy, and be with the rave soldiers who had started out to defend our country.. I have been in the army almost one year now, and have spent the time and enjoyed myself bravely." Jayne
