Apart from technical questions, in which Guibert's enlightened conservatism stands in marked contrast to the doctrinaire progressiveness of Mesnil-Durand, Folard and others, the book is chiefly valued for its broad outlook on the state of Europe, especially of military Europe in the period 1763–1792. One quotation may be given as being a most remarkable prophecy of the impending revolution in the art of war, a revolution which the "advanced" tacticians themselves scarcely foresaw. "The standing armies, while a burden on the people, are 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.
