tary 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 one as against the French, it was important."

The second letter was calculated at the least to call up in General
York's mind all the feelings of bitterness which perhaps for some days
past bad been diminished by the consciousness of his own behaviour
towards the writer.

As the Author entered General York's chamber, the latter called out to
him, "Keep off from me; I will have nothing more to do with you; your
d----d Cossacks have let a letter of Macdonald's pass through them,
which brings me an order to march on Piktrepohnen, in order there to
effect our junction.
