Under these circumstances, with agreeable society, amidst sympathetic friends, in a charming situation, well and profitably employed upon his own work, Flinders spent over five years of his captivity. He never ceased to chafe under the restraint, and to move every available influence to secure his liberty, but it cannot be said that the chains were oppressively heavy. Decaen troubled him very little. Once (in May, 1806) the General's anger flamed up, in consequence of a strong letter of protest received from Governor King of New South Wales. King's affection for Flinders was like that of a father for a son, and on receipt of the news about the Cumberland his indignation poured itself out in this letter to Decaen, with which he enclosed a copy of Flinders' letter to him. It happened that, at the time of the arrival of the letter in Ile-de-France, Flinders was on a visit to Port Louis, where he had been permitted to come for a few days. The result of King's intervention was that Decaen ordered him to return to Wilhelm's Plains, and refused the application he had made to be allowed to visit two friends who were living on the north-east side of the island. John Elder, Flinders' servant, remained with him until June, 1806. He might have left when there was a general exchange of prisoners in August, 1805, and another opportunity of quitting the island was presented in April, 1806, when the lame seaman departed on an American ship bound for Boston. But Elder was deeply attached to his master, and would have remained till the end had not his mind become somewhat unhinged by frequent disappointments and by his despair of ever securing liberation. When his companion, the lame seaman, went away, Elder developed a form of melancholy, with hallucinations, and appeared to be wasting away from loss of sleep and appetite. Permission for him to depart was therefore obtained, and from July, 1806, Flinders was the only remaining member of the Cumberland's company.
