Red Badge of Courage 

"The Red Badge Of Courage" was first published in 1895. Taking place during the American Civil War, the story is about a young private of the Union Army, Henry Fleming, who flees from the field of battle. Overcome with shame, he longs for a wound-a "red badge of courage"-to counteract his cowardice. When his regiment once again faces the enemy, Henry acts as flag-bearer. (Excerts from Wikipedia)
