This war claimed more than 10 million lives. This catastrophe destroyed four empires, including the Russian one. This tragedy broke the history of Europe and the fate of all mankind. A classic work by the greatest British historian and military theorist, who is deservedly put on a par with Clausewitz and Jomini, is rightfully considered one of the best analytical reviews of the First World War. Written “hot on the heels” of the events, when many participants in the hostilities were still alive, this book became not only an invaluable document of the era, but also a training manual on the “strategy of indirect actions.” A must read!
