the historical parts of the work.  I must also mention my much-loved brother, who was my support in the hour of my misfortune, and who has also done much for me in respect of these papers; amongst other things, by carefully examining and putting them in order, he found the commencement of the revision which my dear husband wrote in the year 1827, and mentions in the Notice hereafter annexed as a work he had in view.  This revision has been inserted in the place intended for it in the first book (for it does not go any further).

There are still many other friends to whom I might offer my thanks for their advice, for the sympathy and friendship which they have shown me; but if I do not name them all, they will, I am sure, not have any doubts of my sincere gratitude.  It is all the greater, from my firm conviction that all they have done was not only on my own account, but for the friend whom God has thus called away from them so soon.

If I have been highly blessed as the wife of such a man during one and twenty years, so am I still, notwithstanding my irreparable loss, by the treasure of my recollections and of my hopes, by the rich legacy of sympathy and friendship which I owe the beloved departed, by the elevating feeling which I experience at seeing his rare worth so generally and honourably acknowledged.

The trust confided to me by a Royal Couple is a fresh benefit for which I have to thank the Almighty, as it opens to me an honourable occupation, to which Idevote myself.  May this occupation be blessed, and may the dear little Prince who is now entrusted to my care, some day read this book, and be animated by it to deeds like those of his glorious ancestors.

Written at the Marble Palace, Potsdam, 30th June, 1832.

NOTICE

I look upon the first six books, of which a fair copy has now been made, as only a mass which is still in a manner without form, and which has yet to be again revised.  In this revision the two kinds of War will be everywhere kept more distinctly in view, by which all ideas will acquire a clearer meaning, a more precise direction, and a closer application.  The two kinds of War are, first, those in which the object is the overthrow of the enemy, whether it be that we aim at his destruction, politically, or merely at disarming him and forcing him to conclude peace on our terms; and next, those in which our object is merely to make some conquests on the frontiers of his country, either for the purpose of retaining them permanently, or of turning them to account as matter of exchange in the settlement of a peace.  Transition from one kind to the other must certainly continue to exist, but the completely different nature of the tendencies of the two must everywhere appear, and must separate from each other things which are incompatible.
