Written at the strategic and operational levels, this study frames the Turkish military contributions in a unitary manner by establishing linkages between campaigns and theaters. It also contains the first detailed discussion of Ottoman operations in Galicia, Romania, and Macedonia. Erickson provides a wealth of information on Ottoman Army organization, deployments, strategy, and staff procedures. He examines with particular attention the army's role in the Armenian deportations and the intelligence available to the Turks in 1914 and 1915. Appendixes include biographies of important commanders, the efforts of the Ottoman Air Force, Ottoman casualties, as well as a wartime chronology.
