The really deplorable feature of the affair is that Peron and Freycinet, in their published book and atlas, gave no credit to Flinders for discoveries which they knew perfectly that he had made. They knew where he was while they were working up their material. It does not appear that either of them ever moved in the slightest degree to try to secure his liberation. Peron died in December, 1810. Malte-Brun, who saw him frequently after the return of Baudin's expedition, says that in conversation on the discoveries of Flinders, Peron "always appeared to me to be agitated by a secret sorrow, and has given me to understand that he regretted not being at liberty to say in that regard all that he knew." Flinders also believed Peron to be a worthy man who acted as he did "from overruling authority." Those who have read the evidence printed in this book, exhibiting the detestable conduct of both Peron and Freycinet in repaying indulgence and hospitality by base espionage, will hardly be precipitate in crediting either of them with immaculate motives. There is no evidence that authority was exercised to induce them to name the southern coasts Terre Napoleon, or to give the name Golfe Bonaparte to the Spencer's Gulf of Flinders, that of Golfe Josephine to his St. Vincent's Gulf, that of Ile Decres to his Kangaroo Island, that of Detroit de Lacepede to his Investigator Strait, and so forth. They knew that Flinders had made these discoveries before their own ships appeared in the same waters; they knew that only the fact of his imprisonment prevented his charts from being published before theirs. The names with which they adorned their maps were a piece of courtiership and a means of currying favour with the great and powerful, just as their espionage, and their supply of illicitly-obtained and flavoured information to Decaen in Mauritius, were essays to advance their own interests by unworthy services.
