manner in which it was solved, and the various means invented and employed.
The subject is of course largely technical, but an effort has been made to present the story in such form that the layman can readily understand it. As it is difficult, if not quite impossible, for a naval officer to determine just which of the details that are a part of his daily life, and what incidents of sea experience would interest his civilian friends, the story has been written in collaboration with Mr. Burton J. Hendrick, to whom I am greatly indebted for invaluable assistance ; and who, being an experienced hand at this writing business, deserves all the credit the reader may be disposed to accord him for both the form and such graces of descriptive style as he may be able to detect. While opinions may differ to a certain extent as to the influence exerted upon the campaign by the various forms of tactics, the means and weapons employed, and the general strategy adopted, I have given what I believe to be a consensus of the best informed opinion upon these matters; and I have taken advantage of all of the information now available to insure accuracy in the account of the conditions that confronted the European naval forces, and in the description of the various operations that have been selected as typical examples of this very extraordinary warfare.
It is probably unnecessary to add that this book is published with the full approval of the Navy Department. My correspondence on this subject with the Secretary will be found in the Appendix.
