This book is a retrospect covering the period 1912–1919. It begins with the first Balkan War, and ends with the Peace Conference at Paris. Many of the events described have been dealt with by other writers, and the only justification for adding one more volume to an already well-stocked library, is that the author was an eye-witness of all that he relates and enjoyed peculiar opportunities for studying the situation as a whole. To impressions derived from personal contact with many of the principal actors in this world-drama has been added the easy wisdom which comes after the event. With these qualifications a conscientious effort has been made to arrange the subject matter in proper sequence and to establish some connection between cause and effect—not with a view to carping criticism, but rather to stress the more obvious errors of the past and glean from them some guidance for the future.
