CARL VON CLAUSEWITZ, born 1780, learned his military craft in the Prussian army as it failed to resist Napoleon’s mass army. Dismayed at Prussia’s craven subordination to victorious France, Clausewitz joined the Russian army (hence his appearance at Borodino) before returning to the Prussian army for the campaign that culminated at Waterloo and the final defeat of Bonaparte. Along with the bulk of the European officer class, he had been mesmerized by Napoleon.
