Buonaparte's mission to Genoa had been openly political; secretly it was also a military reconnaissance, and his confidential instructions, virtually dictated by himself, had unfortunately leaked out. They had directed him to examine the fortifications in and about both Savona and Genoa, to investigate the state of the Genoese artillery, to inform himself as to the behavior of the French envoy to the republic, to learn as much as possible of the intentions of the oligarchy--in short, to gather all information useful for the conduct of a war "the result of which it is impossible to foresee." Buonaparte, knowing now that he had trodden dangerous ground in his unauthorized and secret dealings with the younger Robespierre, and probably foreseeing the coming storm, began to shorten sail immediately upon reaching Nice. Either he was prescient and felt the new influences in the air, or else a letter now in the war office at Paris, and purporting to have been written on August seventh to Tilly, the French agent at Genoa, is an antedated fabrication written later for Salicetti's use.[41] Speaking, in this paper, of Robespierre the younger, he said: "I was a little touched by the catastrophe, for I loved him and thought him spotless. But were it my own father, I would stab him to the heart if he aspired to become a tyrant." If the letter be genuine, as is probable, the writer was very far-sighted. He knew that its contents would speedily reach Paris in the despatches of Tilly, so that it was virtually a public renunciation of Jacobinism at the earliest possible date, an anchor to windward in the approaching tempest. But momentarily the trick was of no avail; he was first superseded in his command, then arrested on August tenth, and, fortunately for himself, imprisoned two days later in Fort Carré, near Antibes, instead of being sent direct to Paris as some of his friends were. This temporary shelter from the devastating blast he owed to Salicetti, who would, no doubt, without hesitation have destroyed a friend for his own safety, but was willing enough to spare him if not driven to extremity.
