This book examines in detail, and as objectively as possible, the first year of the Second World War. The sources used here are international in order to avoid a perspective focused on any single nation. It also explores the political machinations and intrigues, as well as the various military campaigns and problems of 1939–1940. In addition to this, the war at sea is closely followed, as well as the reactions of various populations, especially those in , Britain, and , with a sideways glimpse of American thinking in public . The motives behind the war are viewed; important incidents are examined, as are the various styles and issues of leadership. For the student of history, there is also a detailed chronology of every day for the whole year.The book begins with an overview of the driving forces and features of the war, and concludes with a synopsis of the international situation after this one year, from the point of view of the major belligerents. As such, it will appeal to both students and general readers of history.
