Other works of Guibert, besides those mentioned, are: "Observations sur la constitution politique et militaire des armées de S. M. Prussienne" (Amsterdam, 1778), "Eloges" of Marshal Catinat (1775), of Michel de l'Hôpital (1778), and of Frederick the Great (1787). Guibert was a member of the Académie française from 1786, and he also wrote a tragedy, "Le Connétable de Bourbon" (1775) and a journal of travels in France and Switzerland. His final work was "De la force publique considérée par tous ses rapports" (Paris: Didot l'aîné, 1790) in which he contradicted several of the postulates on militias and professional armies. Guibert's writing on the subject - pondering the advantages and disadvantages of militias/conscript armies and mercenaries/professional forces until this day cover most fundamental arguments on the subject.
