CLAUSEN—CLAUSEWITZ

of the French, and at the battle of Salamanca, Clausel, who had succeeded to the command on Marmont being wounded, and had himself received a severe wound, drew off his army with the greatest skill, the retreat on Burgos being conducted by him in such a way that the pursuers failed to make the slightest impression, and had themselves in the end to retire from the siege of Burgos (1812). Early in 1813 Clausel was made commander of the Army of the North in Spain, but he was unable to avert the great disaster of Vittoria. Under the supreme command of Soult he served through the rest of the Peninsular War with unvarying distinction. On the first restoration in 1814 he submitted unwillingly to the Bourbons, and when Napoleon returned to France, he hastened to join him. During the Hundred Days he was in command of an army defending the Pyrenean frontier. Even after Waterloo he long refused to recognize the restored government, and he escaped to America, being condemned to death in absence. He took the first opportunity of returning to aid the Liberals in France (1820), sat in the chamber of deputies from 1827 to 1830, and after the revolution of 1830 was at once given a military command. At the head of the army of Algiers, Clausel made a successful campaign, but he was soon recalled by the home government, which desired to avoid complications in Algeria. At the same time he was made a marshal of France (February 1831). For some four years thereafter he urged his Algerian policy upon the chamber of deputies, and finally in 1835 was reappointed commander-in-chief. But after several victories, including the taking of Mascara in 1835, the marshal met with a severe repulse at Constantine in 1836. A change of government in France was primarily responsible for the failure, but public opinion attributed it to Clausel, who was recalled in February 1837. He thereupon retired from active service, and, after vigorously defending his conduct before the deputies, he ceased to take part in public affairs. He lived in complete retirement up to his death at Secourrieu (Garonne) on the 21st of April 1842.


CLAUSEN, GEORGE (1852–  ), English painter, was born in London, the son of a decorative artist. He attended the design classes at the South Kensington schools from 1867–1873 with great success. He then worked in the studio of Edwin Long, R.A., and subsequently in Paris under Bouguereau and Robert-Fleury. He became one of the foremost modern painters of landscape and of peasant life, influenced to a certain extent by the impressionists with whom he shared the view that light is the real subject of landscape art. His pictures excel in rendering the appearance of things under flecking outdoor sunlight, or in the shady shelter of a barn or stable. His “Girl at the Gate” was acquired for the nation by the Chantrey Trustees and is now at the National Gallery of British Art (Tate Gallery). He was elected associate of the Royal Academy in 1895, and as professor of painting gave a memorable series of lectures to the students of the schools,—published as Six Lectures on Painting (1904) and Aims and Ideals in Art (1906).


CLAUSEWITZ, KARL VON (1780–1831), Prussian general and military writer, was born at Burg, near Magdeburg, on the 1st of June 1780. His family, originally Polish, had settled in Germany at the end of the previous century. Entering the army in 1792, he first saw service in the Rhine campaigns of 1793–1794, receiving his commission at the siege of Mainz. On his return to garrison duty he set to work so zealously to remedy the defects in his education caused by his father’s poverty, that in 1801 he was admitted to the Berlin Academy for young officers, then directed by Scharnhorst. Scharnhorst, attracted by his pupil’s industry and force of character, paid special attention to his training, and profoundly influenced the development of his mind. In 1803, on Scharnhorst’s recommendation, Clausewitz was made “adjutant” (aide-de-camp) to Prince August, and he served in this capacity in the campaign of Jena (1806), being captured along with the prince by the French at Prenzlau. A prisoner in France and Switzerland for the next two years, he returned to Prussia in 1809; and for the next three years, as a departmental chief in the ministry of war, as a teacher in the military school, and as military instructor to the crown prince, he assisted Scharnhorst in the famous reorganization of the Prussian army. In 1810 he married the countess Marie von Brühl.

On the outbreak of the Russian war in 1812, Clausewitz, like many other Prussian officers, took service with his country’s nominal enemy. This step he justified in a memorial, published for the first time in the Leben Gneisenaus by Pertz (Berlin, 1869). At first adjutant to General Phull, who had himself been a Prussian officer, he served later under Pahlen at Witepsk and Smolensk, and from the final Russian position at Kaluga he was sent to the army of Wittgenstein. It was Clausewitz who negotiated the convention of Tauroggen, which separated the cause of Yorck’s Prussians from that of the French, and began the War of Liberation (see Yorck Von Wartenburg; also Blumenthal’s Die Konvention von Tauroggen, Berlin, 1901). As a Russian officer he superintended the formation of the Landwehr of east Prussia (see Stein, Baron Vom), and in the campaign of 1813 served as chief of staff to Count Wallmoden. He conducted the fight at Göhrde, and after the armistice, with Gneisenau’s permission, published an account of the campaign (Der Feldzug von 1813 bis zum Waffenstillstand, Leipzig, 1813). This work was long attributed to Gneisenau himself. After the peace of 1814 Clausewitz re-entered the Prussian service, and in the Waterloo campaign was present at Ligny and Wavre as General Thielmann’s chief of staff. This post he retained till 1818, when he was promoted major-general and appointed director of the Allgemeine Kriegsschule. Here he remained till in 1830 he was made chief of the 3rd Artillery Inspection at Breslau. Next year he became chief of staff to Field-marshal Gneisenau, who commanded an army of observation on the Polish frontier. After the dissolution of this army Clausewitz returned to his artillery duties; but on the 18th of November 1831 he died at Breslau of cholera, which had proved fatal to his chief also, and a little previously, to his old Russian commander Diebitsch on the other side of the frontier.

His collected works were edited and published by his widow, who was aided by some officers, personal friends of the general, in her task. Of the ten volumes of Hinterlassene Werke über Krieg und Kriegführung (Berlin, 1832–1837, later edition called Clausewitz’s Gesammte Werke, Berlin, 1874) the first three contain Clausewitz’s masterpiece, Vom Kriege, an exposition of the philosophy of war which is absolutely unrivalled. He produced no “system” of strategy, and his critics styled his work “negative” and asked “Qu’a-t-il fondé?” What he had “founded” was that modern strategy which, by its hold on the Prussian mind, carried the Prussian arms to victory in 1866 and 1870 over the “systematic” strategists Krismánic and Bazaine, and his philosophy of war became, not only in Germany but in many other countries, the essential basis of all serious study of the art of war. The English and French translations (Graham, On War, London, 1873; Neuens, La Guerre, Paris, 1849–1852; or Vatry, Théorie de la grande guerre, Paris, 1899), with the German original, place the work at the disposal of students of most nationalities. The remaining volumes deal with military history: vol. 4, the Italian campaign of 1796–97; vols. 5 and 6, the campaign of 1799 in Switzerland and Italy; vol. 7, the wars of 1812, 1813 to the armistice, and 1814; vol. 8, the Waterloo Campaign; vols. 9 and 10, papers on the campaigns of Gustavus Adolphus, Turenne, Luxemburg, Münnich, John Sobieski, Frederick the Great, Ferdinand of Brunswick, &c. He also wrote Über das Leben und den Charakter von Scharnhorst (printed in Ranke’s Historisch-politischer Zeitschrift, 1832). A manuscript on the catastrophe of 1806 long remained unpublished. It was used by v. Höpfner in his history of that war, and eventually published by the Great General Staff in 1888 (French translation, 1903). Letters from Clausewitz to his wife were published in Zeitschrift für preussische Landeskunde (1876). His name is borne by the 28th Field Artillery regiment of the German army.
