The locomotive chase in Georgia, which forms what may be called the background of this story, was an actual occurrence of the great Civil War. But I wish to emphasize the fact that the following pages belong to the realm of fiction. Some of the incidents, and the character of Andrews, are historic, whilst other incidents and characters are imaginary. The reader who would like to procure an account of the chase as it really happened should consult the narrative of the Reverend William Pittenger. Mr. Pittenger took part in the expedition organized by Andrews, and his record of it is a graphic contribution to the annals of the conflict between North and South.
