Over the last two militarily turbulent centuries, the surname “Clausewitz” has long since migrated to the category of almost common nouns, and this, probably, best sums up the results of his scientific activity. Clausewitz's works represent almost a unique attempt, on the basis of relevant and politicized material imbued with personal experience, to create a dry military-historical, rational and devoid of political mythology (as far as possible) review. “On War” is undoubtedly a brilliant experience in the analysis of current events, (almost) devoid of the magic of names and slogans, written without the typical errors and prejudices of an eyewitness. Selected chapters from the work “On War” are presented to the reader, accompanied by a preface and comprehensive comments. The publishing layout is saved in PDF A4 format.
