NPS: &#34;The most famous of the dozens of young drummer boys was Johnny Clem of Newark, Ohio. He went to war at the age of ten. In Clem&#39;s first battle, a shell fragment ripped his drum apart. He became known as &#34;Johnny Shiloh.&#34; Gallantry in action two years later brought him promotion to sergeant. Clem made the army a career, and he retired in 1916 with the rank of major general.&#34;
