Did Flinders know of this state of things? Unquestionably he did; and Decaen knew that he knew. He could have informed the British Government, had he chosen to violate his parole; but he was in all things a scrupulously honourable man, and, as he said, "an absolute silence was maintained in my letters." He was constantly hoping that an attack would be made upon the island, and "if attacked with judgment it appeared to me that a moderate force would carry it."* (* Voyage to Terra Australis 2 419.) But all this while the British believed that Ile-de-France was strong, and that a successful assault upon it would require a larger force than they could spare at the time. Even after Flinders had returned to England, when he was asked at the Admiralty whether he thought that a contemplated attack would succeed, his confident assurance that it would was received with doubt. Decaen's "bluff" was superb. On one point, if we may believe St. Elme le Duc, Decaen did Flinders a grave injustice. It was believed, says that writer's manuscript, that Flinders had several times managed to go out at night, that he had made soundings along the coast, and had transmitted information to Bengal which was of use when ultimately the colony was taken by the English. For that charge there is not a shadow of warrant. There is not the faintest ground for supposing that he did not observe his parole with the utmost strictness. Had he supplied information, Ile-de-France would have passed under British rule long before 1810.* (* The belief that Flinders took soundings appears to have been common among the French inhabitants of Port Louis. In the Proceedings of the South Australian Branch of the Royal Geographical Society, 1912 to 1913 page 71, is printed a brief account of the detention of Flinders, by a contemporary, D'Epinay, a lawyer of the town. Here it is stated: "It is found out that at night he takes soundings off the coast and has forwarded his notes to India." Those who gave credence to this wild story apparently never reflected that Flinders had no kind of opportunity for taking soundings.) A few passages written for inclusion in the Voyage to Terra Australis, but for some reason omitted, may be quoted to show how rigorously visiting ships were treated lest information should leak out.* (* Manuscript, Mitchell Library.)
