"The sad condition of the navy in the reign of Louis XV., by closing to officers the brilliant career of bold enterprises and successful battles, forced them to fall back upon themselves. They drew from study the knowledge they were to put to the proof some years later, thus putting into practice that fine saying of Montesquieu, 'Adversity is our mother, Prosperity our step-mother.'... By the year 1769 was seen in all its splendor that brilliant galaxy of officers whose activity stretched to the ends of the earth, and who embraced in their works and in their investigations all the branches of human knowledge. The Académie de Marine, founded in 1752, was reorganized."[9] The Académie's first director, a post-captain named Bigot de Morogues, wrote an elaborate treatise on naval tactics, the first original work on the subject since Paul Hoste's, which it was designed to supersede. Morogues must have been studying and formulating his problems in tactics in days when France had no fleet, and was unable so much as to raise her head at sea under the blows of her enemy. At the same time England had no similar book; and an English lieutenant, in 1762, was just translating a part of Hoste's great work, omitting by far the larger part. It was not until nearly twenty years later that Clerk, a Scotch private gentleman, published an ingenious study of naval tactics, in which he pointed out to English admirals the system by which the French had thwarted their thoughtless and ill-combined attacks.[10] "The researches of the Académie de Marine, and the energetic impulse which it gave to the labors of officers, were not, as we hope to show later, without influence upon the relatively prosperous condition in which the navy was at the beginning of the American war."
