After the Prussian Army of Observation was dissolved, Clausewitz returned to Breslau, and a few days after his arrival was seized with cholera, the seeds of which he must have brought with him from the army on the Polish frontier. His death took place in November 1831.
His writings are contained in nine volumes, published after his death, but his fame rests most upon the three volumes forming his treatise on "War." In the present attempt to render into English this portion of the works of Clausewitz, the translator is sensible of many deficiencies, but he hopes at all events to succeed in making this celebrated treatise better known in England, believing, as he does, that so far as the work concerns the interests of this country, it has lost none of the importance it possessed at the time of its first publication.
