Attack and Defence of Coast-Fortifications [PDF ebook] 

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Again: a great many of the text-books go too much into the details of old forms, and devote too much attention to dead issues. The tendency is to force the young man to spend part of his life in a past age; that is, to encumber his mind with a mass of information which even his grandsire would have been glad to have forgotten.
