One of the first matters which occupied Flinders after his arrival in England was the use of his influence with the Admiralty to secure the release of a few French prisoners of war who were relatives of his friends in Mauritius. In a letter he pointed out that these men were connected with respectable families from whom he himself and several other English prisoners had received kindness.* (* Flinders' Papers.) His plea was successful. There was, surely, a peculiar beauty in this act of sympathy on the part of one who had so recently felt the pain and distress of captivity. Flinders was anxious for news about his old Investigator shipmates. The faithful Elder, he found, had secured an appointment as servant to Admiral Hollowell, then on service in the Mediterranean, and was a great favourite. Franklin was able to enlighten him as to some of the others. Purdie, who had been assistant-surgeon, was surgeon on the Pompey. Inman, who had been sent out to act as astronomer during the latter part of the voyage, was a professor at the Naval College, Portsmouth. Lacy and Sinclair, midshipmen, were dead. Louth was a midshipman on the Warrior. Olive was purser on the Heir Apparent, and Matt, the carpenter, filled that post on the Bellerophon. Of Dr. Bell Franklin knew nothing. "The old ship," he said, "is lying at Portsmouth, cut down nearly to the water's edge." In naval and scientific circles Flinders was the object of much honour and interest. He was received "with flattering attention" at the Admiralty. We find him visiting Lord Spencer, who, having authorised the Investigator voyage, was naturally concerned to hear of its eventful history. Banks took him to the Royal Society and gave a dinner in his honour. The Duke of Clarence, afterwards William IV, himself a sailor, wished to meet him and inspect his charts, and he was taken to see the Prince by Bligh. In 1812 he gave evidence before a Committee of the House of Commons on the penal transportation system.* (* House of Commons Papers, 1812; the evidence was given on March 25th.) What he had to say related principally to the nature of the country he had examined in the course of his explorations. "Were you acquainted with Port Dalrymple?" the chairman asked him. "I discovered Port Dalrymple." "Were you ever at the Derwent?" "I was, and from my report, I believe, it was that the first settlement was made there." He was one of the few early explorers of Australia whose vision was hopeful; and experience has in every instance justified his foreseeing optimism.
