The two-volume Chief of Staff examines the history, development, and role of the military duty position of the chief of staff. Many books have studied history's great commanders and the art of command. None have focused exclusively on the chief of staff -—that key staff officer responsible for translating the ideas of the commander into practical plans that common soldiers can execute successfully on the battlefield. In some cases, it is almost impossible to think of certain great commanders without also thinking of their chief of staff. Napoleon's chief of staff Berthier and Eisenhower's chief of staff Bedell Smith are two examples that are profiled in this work. Zabecki and his collaborators examine the history, development, and role of the chief of staff primarily through profiles of the most important practitioners of the art. These books are published in cooperation with the Association of the United States Army.
