Because he is considered too young to be a soldier, fifteen-year-old William Bircher serves the cause of the Union during the Civil War in the only way he can. Like others his age, he becomes a drummer and accompanies the army on long marches. In these excerpts from his diary, written many years after the war had ended, William describes the hardships of war, including watching comrades die, enduring constant hunger and extreme heat and cold during various seasons, and having to march without shoes. The entries are brief but detailed and are accompanied by illustrations and photographs. This would be a useful addition to a history classroom library collection, especially since it offers a young person's perspective. The book is part of the First-Person Histories series.
