When the first French edition of this book was issued, in January of last year, matters respecting the prosecution of the war had not yet required the serious consideration by Parliament and the country of the question of conscription to maintain to their proper efficiency the Canadian divisions on the firing line. Consequently, I was not then called upon to consider that most important subject. When I had to decide about publishing a second French edition--the first being entirely exhausted--I at first thought of adding to my work a few chapters respecting the most notable events developed by the gigantic struggle shaking the world to its very basic foundation. Foremost amongst them were the Russian sudden Revolution, the solemn entrance of the United States into the great fight, the imperious necessity of the military effort of the Allies far beyond that which had been foreseen, in order to achieve the final victory which will be the only adequate reward of their undaunted determination not to sheathe the sword before Germany will agree to restore peace upon the only possible conditions which will efficiently protect humanity from any other attempt at brutal universal domination. The question of conscription in Canada was the natural outcome of the progress of the deadly conflict between Civilization and barbarism, constitutional Freedom and despotism, democratic institutions and autocracy. I soon realized that I could not properly do justice to such grave subjects in a few pages added to my first book. After mature consideration, I considered it was my duty to undertake to write a second volume. I have so informed the public in the _Advertisement_ which prefaces the second French edition of the first. This second volume I will soon issue, also intending to publish an English synopsis of it, if that of the first volume meets the kind appreciation I hope of my English speaking countrymen. However, pending the publication of the second volume, I think it is my duty to express now my views, in a summary way, on that much discussed question of obligatory military service. Let me preface by saying that they are not new, having originated in my mind more than thirty years ago. The military necessities of the present war have, of course, given them more precision and clearness. Deeply conscious of the sacred duty of all truly loyal British subjects through the present prolonged world crisis for the life or death of human Liberty, I had to consider conscription from the double stand-point of a free citizen of Canada and of my military experience acquired in the course of a service of over forty years.
