The "very diplomatic-looking certificate" which the Governor gave him was dated February 3, 1803. It certified that "Mr. George Bass, of the brigantine Venus, has been employed since the first day of November, 1801, upon His Britannic Majesty's service in procuring provisions for the subsistence of His Majesty's colony, and still continues using those exertions;" and it went on to affirm that should he find it expedient to resort to any harbour in His Catholic Majesty's dominions upon the west coast of America, "this instrument is intended to declare my full belief that his sole object in going there will be to procure food, without any view to private commerce or any other view whatsoever."
Notwithstanding the terms of this certificate, however, there is clear evidence that Governor King was fully aware of the nature of the trade conducted with the Spanish-American colonies by vessels using Port Jackson; and though it may be that Bass did not tell him in so many words what his whole intentions were, King knew that Bass had a large stock of commodities to sell, and could hardly have been ignorant that a considerable portion of them were re-shipped on the Venus for this voyage. In a later despatch he alluded to vessels which carried goods "from hence to the coasts of the Spanish possessions on the west side of America," and he observed "that this must be a forced trade, similar to that carried on among the settlements of that nation and Portugal on the east side of America, and that much risk will attend it to the adventurers."
Bass sailed from Sydney on February 5th, 1803. He never returned, and no satisfactory account of what became of him is forthcoming.* (* The writer of the article on Bass in the Dictionary of National Biography says that "except that he left Australia in 1799 to return to England nothing certain is known of Bass's subsequent history." But we know fairly fully what he was doing up till February, 1803, as related above. The Bass mystery commences after that date. The Encyclopaedia Britannica (11th edition) finds no space for a separate article on this very remarkable man.) Later in 1803 the brig Harrington, herself concerned in the contraband trade, reported that the Venus had been captured and confiscated by the Spaniards in Peru, and that Bass and the mate, Scott, had been sent as prisoners to the silver mines. In December, 1804, Governor King remarked in a despatch to the Secretary of State that he had been "in constant expectation" of hearing from Bass, "to whom, there is no doubt, some accident has occurred." The Harrington had reported the capture of the Venus before King wrote that. Why did he not mention the circumstance to the British Government? Why did he not allude to the country to which he well knew that Bass intended to sail? It would seem that King carefully avoided referring in his official despatches to an enterprise upon which he had good reason to be aware that Bass had embarked.
War between Great Britain and Spain did not break out till December, 1804, after the seizure of the Spanish treasure fleet by British frigates off Cadiz (October 5th). But in previous years, while Spain, under pressure from Napoleon, lent her countenance to his aggressive policy, English privateers had freely plundered Spanish commerce in the south Pacific, and some of them had brought their prizes to Sydney. That this was done with the knowledge of the authorities cannot be doubted. Everybody knew about it. When the French exploring ships were lying at Sydney in 1802, Peron saw there vessels "provided with arms, fitting out for the western coast of America, stored with merchandise of various kinds. These vessels were intended to establish, by force of arms, a contraband commerce with the inhabitants of Peru, extremely advantageous to both parties."
It would not, therefore, be wonderful that the Spanish authorities in Chili or Peru should regard Port Jackson as a kind of wasp's nest, and should look with suspicion on any vessel coming thence which might fall into their hands, however much her commander might endeavour to make of his official certificate declaring the Governor's "full belief" in his lawful intentions. The irritation caused by the use that was being made of Sydney as a privateering and contraband base of operations can be well imagined. As early as December, 1799, indeed, Governor Hunter related that a captured Spanish merchant vessel had been brought into port, and he acknowledged that "this being the second Spanish prize brought hither, we cannot be surprised, should it be known that such captures make a convenience of this harbour, if it should provoke a visit from some of the ships of war from the Spanish settlements on that coast." The Spaniards would naturally be thirsting for revenge; and a ship sailing direct from the port of which the raiders made a "convenience" would be liable to feel their ire, should there be the semblance of provocation. The authorities would have been justified in holding up the Venus if they suspected that she carried contraband goods; and their treatment of her officers and crew might be expected to reflect the temper of their disposition towards Port Jackson and all that concerned it.
If, as the Harrington reported, Bass and his companions were sent to the mines, the Spanish officials managed their act of punishment, or revenge, very quietly. But at that time there was not a formal state of belligerency between England and Spain, though the tension of public feeling in Great Britain concerning Spanish relations with France was acute. If it were considered that such an act as the seizure of the Venus would be likely to precipitate a declaration of war, the motive for secrecy was strong. Secrecy, moreover, would have been in complete conformity with Spanish methods in South America. It is not recorded whether the seizure of the Venus occurred at Callao, Valparaiso or Valdivia; but a British lieutenant, Fitzmaurice, who was at Valparaiso five years later, heard that a man named Bass had been in Lima some years before.
A friend of the Bass family residing at Lincoln in 1852 wrote a letter to Samuel Sidney, the author of The Three Colonies of Australia, stating that Bass's mother last heard of him "in the Straits of China." But this was evidently an error of memory. If Bass ever got out of South America, he would have written to his "dear Bess," to Waterhouse, and to Flinders. The latter, in 1814, wrote of him as "alas, now no more." There is on record a report that he was seen alive in South America in that year, but the story is doubtful. He was a man full of affectionate loyalty to his friends, and it is not conceivable that he would have left them without news of him if any channel of communication had been open, as would have been the case had he been at liberty as late as 1814. His father-in-law made enquiries, but failed to obtain news. The report of the Harrington was probably true, but beyond that we really have no information upon which we can depend. The internal history of Spanish America has been very scantily investigated, and it is quite possible that even yet some diligent student of archives may find, some day, particulars concerning the fate of this brave and adventurous spirit.
The disappearance of Bass's letters to his mother is a misfortune which the student of Australian history must deplore. He was observant, shrewd, an untiring traveller, and an entertaining correspondent. He probably related to his mother, to whom he wrote frequently, the story of his excursions and experiences, and the historical value of all that he wrote would be very great. The letters, said the Lincoln friend, were long, "containing full accounts of his discoveries." His mother treasured them till she died, when they came into the possession of a Miss Calder. She kept them in a box, and used occasionally to amuse herself by reading them. But some time before 1852 Miss Calder went to the box to look at them again, and found that they had disappeared. Whether she had lent them to some person who had failed to return them, or had mislaid them, is unknown. It is possible that they may still be in existence in some dusty cupboard in England, and that we may even yet be gratified by an examination of documents which would assuredly enable us to understand more of the noble soul of George Bass.
It has been mentioned that Flinders and Bass did not meet again after the voyage of the Norfolk and Bass's return to England. Though Sydney was the base of both Flinders in the Investigator and Bass in the Venus in 1802 and 1803, they always had the ill-luck to miss each other. Bass was at Tahiti while Flinders lay in port from May 9th to July 21st, 1802. He returned in November, and left once more on his final voyage in February, 1803. Flinders arrived in Sydney again, after his exploration of the Gulf of Carpentaria, in June, 1803. A farewell letter from him to his friend is quoted in a later chapter.
