inadequate for the achievement of great and decisive results in war, and meanwhile the mass of the people, untrained in arms, degenerates.... The hegemony over Europe will fall to that nation which ... becomes possessed of manly virtues and _creates a national army_"--a prediction fulfilled almost to the letter within twenty years of Guibert's death. In 1773 he visited Germany and was present at the Prussian regimental drills and army manoeuvres; Frederick the Great, recognizing Guibert's ability, showed great favour to the young colonel and freely discussed military questions with him. Guibert's _Journal d'un voyage en Allemagne_ was published, with a memoir, by Toulongeon (Paris, 1803). His _Defense du systeme de guerre moderne_, a reply to his many critics (Neuchatel, 1779) is a reasoned and scientific defence of the Prussian method of tactics, which formed the basis of his work when in 1775 he began to co-operate with the count de St Germain in a series of much-needed and successful reforms in the French army. In 1777, however, St Germain fell into disgrace, and his fall involved that of Guibert who was promoted to the rank of _marechal de camp_ and relegated to a provincial staff appointment. In his semi-retirement he vigorously defended his old chief St Germain against his detractors. On the eve of the Revolution he was recalled to the War Office, but in his turn he became the object of attack and he died, practically of disappointment, on the 6th of May 1790. Other works of Guibert, besides those mentioned, are: _Observations sur la constitution politique et militaire des armees de S. M. Prussienne_ (Amsterdam, 1778), _Eloges_ of Marshal Catinat (1775), of Michel de l'Hopital (1778), and of Frederick the Great (1787). Guibert was a member of the Academy from 1786, and he also wrote a tragedy, _Le Connetable de Bourbon_ (1775) and a journal of travels in France and Switzerland.
