he arrived at.  A paper with which he finished the instruction of H.R.H. the Crown Prince contains the germ of his subsequent works.  But it was in the year 1816, at Coblentz, that he first devoted himself again to scientific labours, and to collecting the fruits which his rich experience in those four eventful years had brought to maturity.  He wrote down his views, in the first place, in short essays, only loosely connected with each other.  The following, without date, which has been found amongst his papers, seems to belong to those early days.

“In the principles here committed to paper, in my opinion, the chief things which compose Strategy, as it is called, are touched upon.  I looked upon them only as materials, and had just got to such a length towards the moulding them into a whole.

“These materials have been amassed without any regularly preconceived plan.  My view was at first, without regard to system and strict connection, to put down the results of my reflections upon the most important points in quite brief, precise, compact propositions.  The manner in which Montesquieu has treated his subject floated before me in idea.  I thought that concise, sententious chapters, which I proposed at first to call grains, would attract the attention of the intelligent just as much by that which was to be developed from them, as by that which they contained in themselves.  I had, therefore, before me in idea, intelligent readers already acquainted with the subject.  But my nature, which always impels me to development and systematising, at last worked its way out also in this instance.  For some time I was able to confine myself to extracting only the most important results from the essays, which, to attain clearness and conviction in my own mind, I wrote upon different subjects, to concentrating in that manner their spirit in a small compass; but afterwards my peculiarity gained ascendency completely—­I have developed what I could, and thus naturally have supposed a reader not yet acquainted with the subject.

“The more I advanced with the work, and the more I yielded to the spirit of investigation, so much the more I was also led to system; and thus, then, chapter after chapter has been inserted.

“My ultimate view has now been to go through the whole once more, to establish by further explanation much of the earlier treatises, and perhaps to condense into results many analyses on the later ones, and thus to make a moderate whole out of it, forming a small octavo volume.  But it was my wish also in this to avoid everything common, everything that is plain of itself, that has been said a hundred times, and is generally accepted; for my ambition was to write a book that would not be forgotten in two or three years, and which any one interested in the subject would at all events take up more than once.”
