This is the 1942, World War II edition, "a book for soldiers and civilians anxious to understand war news" of the military strategy classic: "Principles of War" by General Carl von Clausewitz (1780-1831).  From the dust jacket:  Clausewitz wrote this history-making "memorandum" for King Frederick William IV of Prussia and gave it the full descriptive title "The Most Important Principles for the Conduct of War to Complete My course of Instruction of His Royal Highness the Crown Prince." Into it, he condensed all of the theories and observations he ultimately expanded to produce his great military classic "On War".  In this edition of "Principles of War", the full text of Clausewitz is augmented by an introduction and extensive explanatory notes by the translator, Hans W. Gatzke, of Williams College.

The 82-page book measures 5 1/4" X 8" with maroon board covers, with gilt lettering clear and bold on cover and spine.  The book is in very nice condition with binding quite solid, light edge wear to spine and covers, and a few penciled numbers, perhaps an old price, on the front flyleaf the only writing found in book. The dust jacket is in two pieces with several cuts to edges with colorful cover picture clear and clean.  Please refer to nine photographs, with and without dust jacket, accompanying this listing.
