Frederick the Great (1712–1786), King of Prussia, initiated the Seven Years' War in 1756; outfought the formidable French, Russian, and Austrian armies aligned against him; and established Prussia as a major power, thereby decisively influencing the next two centuries of European history. He was also a brilliant military thinker whose observations arose from extensive battlefield experience.This volume presents a balanced selection from Frederick's writings on strategy, tactics, and mobility; the problems of logistics and a two-front war; the combined use of infantry, cavalry, and artillery; the history of the Prussian army; the critical battles of the Seven Years' War; generalship as an art; and much more. A majority of this material is translated here for the first time in English and available nowhere else. The result is an invaluable glimpse into the inner thoughts of a military genius.
