While directing the means of attaining these successes, Buonaparte, at the same time, acquired a complete acquaintance with that Alpine country, in which he was shortly to obtain victories in his own name, not in that of others, who obtained reputation by acting on his suggestions. But, while he was thus employed, he was involved in an accusation before the Convention, which, had his reputation been less for approved patriotism, might have cost him dear. In his plans for the defence of the Mediterranean, Napoleon had proposed repairing an old state prison at Marseilles, called fort Saint Nicholas, that it might serve as a powder Magazine. This plan his successor on the station proceeded to execute, and by doing so, gave umbrage to the patriots, who charged the commandant of artillery then at Marseilles, and superintending the work, with an intention to rebuild this fort, to serve as a Bastile for controlling the good citizens. The officer being summoned to the bar of the Convention, proved that the plan was not his own, but drawn out by Buonaparte. The representatives of the army in Italy, however, not being able to dispense with his services, wrote to the Convention in his behalf, and gave such an account of the origin and purpose of the undertaking, as divested it of all shade of suspicion even in the suspicious eye of the Committee of Public Safety.[63] In the remainder of the year 1794, there was little service of consequence in the army of Italy, and the 9th and 10th Thermidor (27th and 28th July) of that year, brought the downfall of Robespierre, and threatened unfavourable consequences to Buonaparte, who had been in close communication with the tyrant's brother, and was understood to have participated in the tone of exaggerated patriotism affected by his party. He endeavoured to shelter himself under his ignorance of the real tendency of the proceedings of those who had fallen,--an apology which resolves itself into the ordinary excuse, that he found his late friends had not been the persons he took them for. According to this line of defence, he made all haste to disclaim accession to the political schemes of which they were accused. "I am somewhat affected," he wrote to a correspondent,[64] "at the fate of the younger Robespierre; but, had he been my brother, I would have poniarded him with my own hand, had I been aware that he was forming schemes of tyranny."
