Walter Clark was a young University of North Carolina graduate and was just 17 (17-year-old college grad?) when he was elected major of the 6th Battalion N.C. Jr. Reserves in May 1864. When it consolidated with another battalion to form the First Regiment N.C. Junior Reserves in June, he was elected major of that unit as well.
After the war he became a judge. In 1901, he edited the series of books "Histories of Several Regiments and Battalions from North Carolina in the Great War 1861-'65."
While the young soldiers were in the military these young soldiers experienced the tedium of camp life, drills and guard duty, just like the older regiments They had long marches, faced bad weather and many died from disease.
