impudent assurance, and lost when the man of talents is called upon to
act and the fool presents himself.

Baron von Mack served as an aide-de-camp under Field-marshal Laudon,
during the last war between Austria and Turkey, and displayed some
intrepidity, particularly before Lissa. The Austrian army was encamped
eight leagues from that place, and the commander-in-chief hesitated to
attack it, believing it to be defended by thirty thousand men. To decide
him upon making this attack, Baron von Mack left him at nine o'clock at
night, crossed the Danube, accompanied only by a single Uhlan, and
penetrated into the suburb of Lissa, where he made prisoner a Turkish
officer, whom, on the next morning at seven o'clock, he presented to his
general, and from whom it was learnt that the garrison contained only six
thousand, men. This personal temerity, and the applause of Field-marshal
Laudon, procured him then a kind of reputation, which he has not since
been able to support. Some theoretical knowledge of the art of war, and
a great facility of conversing on military topics, made even the Emperor
Joseph conceive a high opinion of this officer; but it has long been
proved, and experience confirms it every day, that the difference is
immense between the speculator and the operator, and that the generals of
Cabinets are often indifferent captains when in the camp or in the field.

Preceded by a certain celebrity, Baron von Mack served, in 1793, under
the Prince of Coburg, as an adjutant-general, and was called to assist at
the Congress at Antwerp, where the operations of the campaign were
regulated. Everywhere he displayed activity and bravery; was wounded
twice in the month of May; but he left the army without having performed
anything that evinced the talents which fame had bestowed on him. In
February, 1794, the Emperor sent him to London to arrange, in concert
with your Government, the plans of the campaign then on the eve of being
opened; and when he returned to the Low Countries he was advanced to a
quartermaster-general of the army of Flanders, and terminated also this
unfortunate campaign without having done anything to justify the
reputation he had before acquired or usurped. His Sovereign continued,
nevertheless, to employ him in different armies; and in January, 1797, he
was appointed a Field-marshal lieutenant and a quartermaster-general of
the army of the Rhine. In February he conducted fifteen thousand of the
troops of
