But reverses began now to attend the army in Italy. Defeat followed defeat. They were driven by the Austrians from the posts to which Napoleon had conducted them, and were retreating before their foes. The Committee of Public Safety were in great trepidation. In their ignorance they knew not what orders to issue. Some one who had heard of Napoleon's achievements among the Alps suggested his name. He was called into the meetings of the committee for advice. The local and technical information he had acquired, his military science, and the vast resources of his highly cultivated mind, placed him immediately at the head of the committee. Though young in years, and still more youthful in appearance, his gravity, his serious and pensive thoughtfulness, gave oracular weight to his counsels, and his plans were unhesitatingly adopted. He had studied the topography of the Maritime Alps with the most enthusiastic assiduity, and was familiar with the windings and characteristics of every stream, and the course of mountain ranges, and with the military capabilities of the ravines and glens. The judicious dispositions which he proposed of the various divisions of the army arrested the tide of Austrian conquest, and enabled the French, though much inferior in number to their allied foes, to defend the positions they had been directed to occupy. During all this time, however, while Napoleon, in the committee-room in Paris, was guiding the movements of the army in Italy, he was studying in the public libraries, during every leisure moment, with an assiduity so intense and inexhaustible that it could not have been surpassed had he been inspired with the highest ambition for literary and scientific honors.
