Wawro charts the decline of the Habsburg Empire before the outbreak of the Great War and reconstructs the great battles in Serbia and on the Eastern Front in some detail. He charts the collapse of the Empire triggered by the disintegration of the Austro-Hungarian Army in the conflict. This is an important addition to the rather neglected story of, particularly, the Eastern Front. Although the book is not completely about the Austro-Hungarian Army, that is the central theme of the book which explains why it has been categorised accordingly in this Collection.
