Guischard, Charles Gottlieb

, called Quintus Icilius, an able writer on military tactics, was born at Magdeburg, and studied at the universities of Halle, Marpurg, and Leyden, where he applied to the classics, theology, and the oriental languages. He first carried arm* in the service of the United Provinces, and while thus | einployed found leisure to prepare materials for his “Memoirs Militaires sur les Grecs et les Remains,” which induced him to obtain permission to visit England, where he re^­mained a year. The work was at length published, in two volumes quarto, 1757, received with much approbation, and went through five editions in France and Holland. In the same year he entered as a volunteer in the allied army, acquired the esteem of Ferdinand of Brunswick, and was recommended to the notice of Frederic II. of Prussia, who kept him near his person, often conversed with him on the art of war, and on account of his great knowledge on this subject, gave him the name of Quintus Icilius, the com* mander of Caesar’s tenth legion, when he appointed him to the command of a regiment formed out of the refuse of all nations, during the heat of the war. At the general peace he was one of the few persons whom his majesty admitted into his convivial parties at Potsdam, and to whom he gave the freest access to his library and coins, which latter Guise-hard increased so much, that he valued both at the sum of a hundred thousand dollars. The king, however, in his latter days, treated him with much disrespect, and took every opportunity to mortify him in the presence of others. Giiiscliard died May 13, 1775. Frederic purchased his library of his heirs for the sum of 12,000 dollars. Besides the work already mentioned, he was author of a very useful work to military or classical students, entitled “Memoires Critiques et Historiques sur plusieurs Points d’Antiquites Militaires,” in 4 vols. Hvo. Gibbon, who read his “Military Memoirs” with great attention, bestows high encomiums on him, and considers him as very superior to Folard, whom however Guischard affected too much to undervalue. 1
