Le Naturaliste was lying at anchor when Flinders' arrived with the Investigator in May. Learning from him of the meeting with Le Geographe in Encounter Bay in the previous month, and inferring that Baudin would sail for Mauritius after finishing what he had to do on the southern coast, Hamelin determined also to make his way to the French colony. He left Sydney harbour on May 18, with the intention of rounding the southern extremity of Tasmania, and striking across the Indian Ocean from that point. But here again fearful storms were encountered. "The sea was horrible; the winds blew with fury and in squalls; torrents of rain fell incessantly"; and, increasing the misfortunes, the westerly winds were so strong at the time when the ship was endeavouring to turn westward, that no headway could be made. Hamelin's men were already on short rations, but even so the supplies would not suffice for a voyage to Mauritius, unless a fairly rapid passage could be made. The contrary winds, fogs, and storms of "the roaring forties" offered no such assurance; and the French captain, casting a "longing, lingering look behind" at the comforts and hospitalities of Port Jackson, determined to double back on his tracks. He re-traversed the east coast of Tasmania, and entered Port Jackson for the second time on July 3, to find that his chief and the leading ship of the expedition had been snugly berthed there during the past fortnight. "And so," Peron comments, "were united for the second time, and by the most inconceivable luck, two ships which, owing to the obstinacy of the commandant, had had no appointed rendezvous, and were twice forced to navigate independently at two periods of the voyage when it would have been most advantageous for them to act in concert." As the two French vessels lay at Sydney for nearly six months, during which time the officers and men mingled freely with the population of the colony, whilst the naturalists and artists occupied themselves busily with the work of their special departments, the occurrences have a two-fold interest for one who wishes to appreciate the significance of Baudin's expedition. There is, first, the interest arising from the observations of so intelligent a foreign observer as Peron* was, concerning the British colony within fifteen years after its foundation; and there is, secondly, the special interest pertaining to the reception and treatment of the expedition by the governing authorities, their suspicions as to its motives, and the consequences which arose therefrom. (* Curiously enough, there was another Peron who visited Port Jackson in a French ship in 1796, and gave an interesting account of it in a book which he wrote--Memoires du Capitaine Peron, two volumes Paris 1824. But the two men were not related. The nautical Captain Peron was born at Brest in 1769.)
