In order not to frighten the intelligent reader by such commonplaces, and to make the little good that there is distasteful by pouring water upon it, the Author has preferred to give in small ingots of fine metal his impressions and convictions, the result of many years’ reflection on War, of his intercourse with men of ability, and of much personal experience. Thus the seemingly weakly bound-together chapters of this book have arisen, but it is hoped they will not be found wanting in logical connection. Perhaps soon a greater head may appear, and instead of these single grains, give the whole in a casting of pure metal without dross. BRIEF MEMOIR OF GENERAL CLAUSEWITZ (BY TRANSLATOR) The Author of the work here translated, General Carl Von Clausewitz, was born at Burg, near Magdeburg, in 1780, and entered the Prussian Army as Fahnenjunker (_i.e._, ensign) in 1792. He served in the campaigns of 1793-94 on the Rhine, after which he seems to have devoted some time to the study of the scientific branches of his profession. In 1801 he entered the Military School at Berlin, and remained there till 1803. During his residence there he attracted the notice of General Scharnhorst, then at the head of the establishment; and the patronage of this distinguished officer had immense influence on his future career, and we may gather from his writings that he ever afterwards continued to entertain a high esteem for Scharnhorst. In the campaign of 1806 he served as Aide-de-camp to Prince Augustus of Prussia; and being wounded and taken prisoner, he was sent into France until the close of that war. On his return, he was placed on General Scharnhorst’s Staff, and employed in the work then going on for the reorganisation of the Army. He was also at this time selected as military instructor to the late King of Prussia, then Crown Prince. In 1812 Clausewitz, with several other Prussian officers, having entered the Russian service, his first appointment was as Aide-de-camp to General Phul. Afterwards, while serving with Wittgenstein’s army, he assisted in negotiating the famous convention of Tauroggen with York. Of the part he took in that affair he has left an interesting account in his work on the “Russian Campaign.” It is there stated that, in order to bring the correspondence which had been carried on with York to a termination in one way or another, the Author was despatched to York’s headquarters with two letters, one was from General d’Auvray, the Chief of the Staff of Wittgenstein’s army, to General Diebitsch, showing the arrangements made to cut off York’s corps from Macdonald (this was necessary in order to give York a plausible excuse for seceding from the French); the other was an intercepted letter from Macdonald to the Duke of Bassano. With regard to the former of these, the Author says, “it would not have had weight with a man like York, but for a military justification, if the Prussian Court should require
