addition to this, we may say, considerable practical training (note, enormous and varied indeed compared to any obtainable in the present day), he also possessed a comprehensive and thorough knowledge of military history, and also an uncommonly clear perception of general history" (Von Caemmerer). After the Peace he was employed in a command on the Rhine. In 1818 he became major-general, and was made Director of the Military School at Berlin. Here he remained for some years. This was the chief period of his writings. As General von Caemmerer, in his "Development of Strategical Science," puts it: "This practical and experienced, and at the same time highly cultured soldier, feels now, in peaceful repose, as he himself confesses, the urgent need to develop and systematize the whole world of thought which occupies him, yet also resolves to keep secret till his death the fruit of his researches, in order that his soul, which is thirsting for _Truth_, may be safely and finally spared all temptations from subordinate considerations." In 1830 he was appointed Director of Artillery at Breslau, and, having no more time for writing, sealed up and put away his papers, unfinished as they were. In the same year he was appointed chief-of-the-staff to Field-Marshal Gneisenau's army. In the winter of that year war with France was considered imminent, and Clausewitz had prospects of acting as chief of the general staff of the Commander-in-Chief Gneisenau. He then drew up two plans for war with France, which bear the stamp of that practical knowledge of war and adaptation of means to ends which distinguish his writings. In the same year the war scare passed away, the army of Gneisenau was disbanded, and Clausewitz returned to Breslau, where after a few days he was seized with cholera, and died in November, 1831, aged only 51. His works were published after his death by his widow. CHAPTER II THE INFLUENCE OF CLAUSEWITZ ON MODERN POLICY AND WAR From the day of their publication until now the influence of the writings of Clausewitz has been steadily growing, till to-day it is impossible to over-estimate the extent of that influence upon modern military and political thought, especially in Germany. As General von Caemmerer, in his "Development of Strategical Science," says: "Karl von Clausewitz, the pupil and friend of Scharnhorst and the confidant of Gneisenau, is in Germany generally recognized as the most prominent theorist on war, as the real philosopher on war, to whom our famous victors on the more modern battlefields owe their spiritual training." Field-Marshal Moltke was "his most distinguished pupil," and adapted the teaching of Clausewitz to the conditions of to-day.
