The book includes essays and individual chapters from the works of F. Mehring, which highlight the evolution of military art, starting from the Greco-Persian wars to the Napoleonic ones. It will be unusual for the Russian reader that the author examines the history of a number of wars from the position of Prussia and its national interests. But this position of F. Mering makes the book even more fascinating and exciting. It is intended for a wide range of readers and, undoubtedly, will not leave them indifferent and will awaken even greater interest in military history.
