That, however, was only a mere preliminary. Upon questions of tactics each tactician consulted held a different view, and each criticised adversely the other's suggestions.

One way alone remained open—namely, to take the facts exactly as they stood, add the additional strength of the opposing nations as they at present are, and then draw logical conclusions. This, aided by experts, was done: and after many days of argument with the various authorities, we succeeded in getting them in accord as to the general practicability of an invasion.

Before putting pen to paper it was necessary to reconnoitre carefully the whole of England from the Thames to the Tyne. This I did by means of a motor-car, travelling 10,000 miles of all kinds of roads, and making a tour extending over four months. Each town, all the points of vantage, military positions, all the available landing places on the coast, all railway connections, and telephone and telegraph communications, were carefully noted for future reference. With the assistance of certain well-known military experts, the battlefields were carefully gone over and the positions marked upon the Ordnance map. Thus, through four months we pushed on day by day collecting information and material, sometimes in the big cities, sometimes in the quietest and remotest hamlets, all of which was carefully tabulated for use.

Whatever critics may say, and however their opinions may differ, it can only be pointed out, first, that the "general idea" of the scheme is in accordance with the expressed and published opinions of the first strategists of to-day, and that, as far as the forecast of events is concerned, it has been written from a first-hand knowledge of the local colour of each of the scenes described. The enemy's Proclamations reproduced are practically copies of those issued by the Germans during the war of 1870.

That the experts and myself will probably be condemned as alarmists and denounced for revealing information likely to be of assistance to an enemy goes without saying. Indeed, an attempt was made in the House of Commons to suppress its publication altogether. Mr. R. C. Lehmann, who asked a question of the Prime Minister, declared that it was "calculated to prejudice our relations with the other Powers," while the late Sir H. Campbell-Bannerman, in a subsequent letter apologising to me for condemning in the House a work he had not read, repeated that it was likely to "produce irritation abroad and might conceivably alarm the more ignorant public at home."

Such a reflection, cast by the late Prime Minister upon the British nation was, to say the least, curious, yet it only confirmed the truth that the Government are strenuously seeking to conceal from our people the appalling military weakness and the consequent danger to which the country is constantly open.

To be weak is to invite war: to be strong is to prevent it.

To arouse our country to a sense of its own lamentable insecurity is the object of this volume, which is somewhat compressed from the form in which it originally appeared, and that other nations besides ourselves are interested in England's grave peril is proved by the fact that it has already been published in the German, French, Spanish, Danish, Russian, Italian, and even Japanese languages.
