I have recently Finished reading a book titled “The Red Badge of Courage”.
The book is about a young man, Henry, who leaves home and joins the Union Army.
During his first battle he runs away.
Then he wanders around just thinking about weird things, until he finds his regiment and joins them again.
He fights in the next few battles without running away, and is noticed by the commader for his courage (he lead a charge into enemy lines).
At the end of the book, the Civil War is ending and he is preparing to return to his home.
