The book is The Capturing a Locomotive A History of Secret Service in the Late War. War has a secret as well as a public story. Marches and battles are open to the popular gaze; but enterprises of another class are in their very nature secret, and these are scarcely less important and often much more interesting than the former. The enterprise described in these pages possesses all the unity of a drama, from the first plunge of the actors into the heart of the enemy's country, through all their adventures and changing fortunes, until the few survivors stood once more under the old flag! No single story of the war combines so many of the hidden, underground elements of the contest against rebellion as this. In telling the story all fictitious embellishments have been rejected. No pains have been spared to ascertain the exact truth, and the reader will find names, dates, and localities so fully given that it will be easy to verify the prominent features of the account.
