There was, therefore, no longer any purpose in prolonging the captivity of the prisoner who was feared on account of his knowledge of the situation; and Decaen availed himself of the first opportunity presented in 1810 to grant Flinders his longed-for release. In March, Mr. Hugh Hope was sent to Ile-de-France by Lord Minto (who had become Governor-General of India in 1807) to negotiate for the exchange of prisoners. This gentleman had done his best to secure Flinders' release on a former occasion, and had been refused. But now Decaen realised that the end was drawing near, and there was no sound military purpose to serve in keeping the prisoner any longer. It is quite probable that he would have been glad if information had been conveyed to the British which would expedite the inevitable fight and the consequent fall of French power in Mauritius. On March 15th Flinders received a letter from Mr. Hope informing him that the Governor had consented to his liberation. A fortnight later came official confirmation of the news in a letter from Colonel Monistrol, who assured him of the pleasure he had in making the announcement. His joy was great. At once he visited his French friends in the neighbourhood to give them the news and bid them farewell; next day he took an affectionate leave of the kind family who had been his hosts for four years and a half; and as soon as possible he departed for Port Louis, where he stayed with his friend Pitot until he went aboard the cartel. At the end of the month a dinner was given in his honour by the president of the Societe D'Emulation, to which a large number of English men and women were invited. When Flinders arrived in Ile-de-France, more than six years before, he could speak no French and could only decipher a letter in that language with the aid of a dictionary; but now, when he found himself again in the company of his own countrymen, he experienced a difficulty in speaking English! On June 13th, Flinders' sword was restored to him. He was required to sign a parole, wherein he pledged himself not to act in any service which might be considered as directly or indirectly hostile to France or her allies during the present war. On the same day the cartel Harriet sailed for Bengal. Flinders was free: "after a captivity of six years five months and twenty-seven days I at length had the inexpressible pleasure of being out of the reach of General Decaen." Rowley's blockading squadron was cruising outside the port, and the Harriet communicated with the commodore. It was ascertained that the sloop Otter was running down to the Cape with despatches on the following day, and Flinders had no difficulty in securing a passage in her. After dining with Rowley he was transferred to the Otter. He was delayed for six weeks at the Cape, but in August embarked in the Olympia, and arrived in England on the 23rd of October, after an absence of nine years and three months.
