Intense application to the work in hand brought about a recurrence of the constitutional internal trouble which had occasioned some pain in Mauritius. The illness became acute at the end of 1813. He was only 39 years of age, but Mrs. Flinders wrote to a friend that he had aged so much that he looked 70, and was "worn to a skeleton." He mentioned in his journal that he was suffering much pain. Yet he was never heard to complain, and was never irritable or troublesome to those about him. He was full of kindness and concern for his friends. We find him attending sittings of the Admiralty Court, where his friend Pitot had a suit against the British Government, and he interested himself in the promotion of two of his old Investigator midshipmen. He urged upon the Admiralty with all his force that his own branch of the naval service was as honourable and as deserving of official recognition as war service. The only inducement for young officers to join a voyage of discovery, and forego the advantages arising from prizes and active service, was the reasonable certainty of promotion on their return. "This," he observed, "certainly has been relied upon and fulfilled in expeditions which returned in time of peace, when promotion is so difficult to be obtained; whereas I sailed and my officers returned during a war in which promotion was never before so liberally bestowed. Yet no one of my officers, so far as I have been able to ascertain, has received promotion for their services in that voyage, although it has been allowed the service was well executed."* (* Flinders' Papers.)
The illness increased during 1814, while the "Voyage" and its accompanying atlas were passing through the press. He never saw the finished book. The first copy of it came from the publishers, G. and W. Nicol, of Pall Mall, on July 18th, on the day before he died; but he was then unconscious. His wife took the volumes and laid them upon his bed, so that the hand that fashioned them could touch them. But he never understood. He was fast wrapped in the deep slumber that preceded the end. On the 19th he died. His devoted wife stood by his pillow, his infant daughter (born April 1st, 1812) was in an adjoining room, and there was one other friend present. Just before the brave life flickered out, he started up, and called in a hoarse voice for "my papers." Then he fell back and died.
Upon the manuscript of the friend who wrote an account of his death, there is pencilled a brief memorandum, which chronicles a few words muttered some time before death touched his lips. The pencil-writing is rubbed and only partly decipherable, but the letters "Dr." are distinct. I take the meaning to be that the doctor attending him heard him murmur the words. They are: "But it grows late, boys, let us dismiss!" One can easily realise the kind of picture that floated before the mind of the dying navigator. It was, surely, a happy vision of a night among friends and companions, who had listened with delight to the vivid talk of him who had seen and done so much in his wonderful forty years of life. In such a company his mates would not be the first to wish to break the spell, so he gave the word: "it grows late, boys, let us dismiss."
Flinders died at 14 London Street, Fitzroy Square, and was buried in the graveyard of St. James's, Hampstead Road, which was a burial ground for St. James's, Piccadilly. No man now knows exactly where his bones were laid.* (* The vicar of St. James's, Piccadilly, who examined the burial register in response to an enquiry by Mr. George Gordon McCrae, of Melbourne, in 1912, states that the entry was made, by a clerical error, in the name of Captain Matthew Flanders, aged 40.) A letter written years later by his daughter, Mrs. Petrie, says: "Many years afterwards my aunt Tyler went to look for his grave, but found the churchyard remodelled, and quantities of tombstones and graves with their contents had been carted away as rubbish, among them that of my unfortunate father, thus pursued by disaster after death as in life."
On the 25th of the same month died Charles Dibdin, who wrote the elegy of the perfect sailor:
"Here a sheer hulk lies poor Tom Bowling. The darling of our crew, No more he'll hear the tempest howling For death has broached him to."
During his last years in London, Flinders lodged in six houses successively, and it may be as well to enumerate them. They were, 16 King Street, Soho, from November 5th, 1810; 7 Nassau Street, Soho, from January 19th, 1811; 7 Mary Street, Brook Street, from 30th September, 1811; 45 Upper John Street, Fitzroy Square, from March 30th, 1813; 7 Upper Fitzroy Street, from May 28th, 1813; and 14 London Street, Fitzroy Square, from February 28th, 1814.
A letter from the widow to her husband's French friend Pitot, evidently in answer to a message of sympathy, is poignant: "You who were in a measure acquainted with the many virtues and inestimable qualities he possessed, will best appreciate the worth of the treasure I have lost, and you will easily imagine that, were the whole universe at my command, it could offer no compensation; and even the tenderest sympathy of the truest friend avails but little in a case of such severe trial and affliction. You will not be surprised when I say that sorrow continually circles round my heart and tears are my daily companion. 'Tis true the company of my little girl soothes and cheers many an hour that would otherwise pass most wearily away, but life has lost its chief charm, and the world appears a dreary wilderness to me.
