Unlike later wars in American history, young people were involved in all aspects of the Civil War, including fighting on the battlefield. William Black, the youngest wounded soldier, was twelve when his left hand and arm were shattered by an exploding shell. An unknown number of soldiers—probably around five percent—were under eighteen, and some were as young as ten. Other boys and girls served as scouts or nurses for the wounded. Yet even those who did not participate in the war itself saw their lives altered by the conflict. During wartime, young people had to grow up quickly, assuming the responsibilities of absent relatives.
