The Military Reorganization Commission opened military schools in Königsberg and Breslau. On 15 October 1810 Scharnhorst opened the General War School ("Allgemeine Kriegsschule"), on the same day that the new the University of Berlin opened nearby. The General War School trained selected officers for three years. One of its first directors was Carl von Clausewitz, who served until 1830. His monumental work On War ("Vom Kriege") was published posthumously. From his studies and experiences during the Napoleonic Wars, he wrote a syllabus which became the staff's central doctrine. This standardization of doctrine which was an attempt to grasp the philosophy underlying warfare, rather than setting a narrow set of rules such as those laid down by Antoine-Henri Jomini was one of the distinguishing features of the Prussian General Staff.
