this is not enough. If we are to retain our position as the first nation in the world we must be prepared to defend any raid made upon our shores.
The object of this book is to illustrate our utter unpreparedness for war, to show how, under certain conditions which may easily occur, England can be successfully invaded by Germany, and to present a picture of the ruin which must inevitably fall upon us on the evening of that not far-distant day.
Ever since Lord Roberts formulated his plans for the establishment of rifle-clubs I have been deeply interested in the movement; and after a conversation with that distinguished soldier the idea occurred to me to write a forecast, based upon all the available military and naval knowledge—which would bring home to the British public vividly and forcibly what really would occur were an enemy suddenly to appear in our midst. At the outset it was declared by the strategists I consulted to be impossible. No such book could ever be written, for, according to them, the mass of technical detail was far too great to digest and present in an intelligible manner to the public.
Lord Roberts, however, gave me encouragement. The skeleton scheme of the manner in which England could be invaded by Germany was submitted to a number of the highest authorities on strategy, whose names, however, I am not permitted to divulge, and after many consultations, much criticism, and considerable difference of opinion, the "general idea," with amendment after amendment, was finally adopted.
