Burney, Fitte and Destéfani variant routes

Royal Navy officer and author James Burney conjectured that La Roché might have visited not South Georgia but the

In a variant Falklands version, Argentine historian Ernesto Fitte identified La Roché Strait with the

" – and narrowing to less than 5 km rather than "10 leagues little more or less." Argentine naval officer and historian Laurio Destéfani referred to the possibility of Roché Island actually being Beauchene Island itself. Yet there is no land to the southeast of Beauchene, whether within visibility range or further beyond, hence no "said Passage." Furthermore, with its elevation of 70 m that island could hardly be one of the two "high lands" in Seixas y Lovera's summary. One common drawback of Burney's conjecture and its varieties is that the Falkland Islands are not known for their "snow mountains near the coast." Another drawback would stem from La Roché's approaching his island from the west ("the Land which they now began to see toward the East"). Indeed, in such a westerly location with respect to the Falklands he would have already been in the "North Sea," even before his two-week anchorage and before sailing his strait – something refuted by the report narrating that, on departure, "steering ENE they found themselves in the No. Sea." (According to American historian Mark Peterson, "maps from the sixteenth and seventeenth centuries commonly referred to the entire

Varnhagen-Duperrey hypothesis

Brazilian historian Francisco Adolfo de Varnhagen, in following French naval officer and explorer Louis-Isidore Duperrey, supposed that South Georgia might have been discovered as early as April 1502 by a Portuguese expedition led by Gonçalo Coelho, finding evidence of this in an episode reported by Florentine
Amerigo Vespucci Amerigo Vespucci ( , ; 9 March 1454 – 22 February 1512) was an Italians, Italian explorer and navigator from the Republic of Florence for whom "Naming of the Americas, America" is named. Vespucci participated in at least two voyages of the A ...

Vespucci made no mention of snow/ice cover, something with which South Georgia invariably impresses seafarers. For instance, Cook described Possession Bay, South Georgia like this: "The head of the bay, as well as two places on each side, was terminated by perpendicular ice-cliffs of considerable height. Pieces were continually breaking off, and floating out to sea; and a great fall happened while we were in the bay, which made a noise like cannon … and the valleys lay covered with everlasting snow."

Isle Grande (Gough Island) landing and Cook's mapping error

via Le Maire Strait and Cape Horn, Capt. Lapérouse made in November–December 1785 a forty-day detour from the Brazilian island of Santa Catarina to an area north of South Georgia in fruitless search of Isle Grande. On his way to rounding Cape Saint John and Cape Horn, Colnett wrote in April 1793: "In this course I ran directly over the situations in which the Isle of Grand is placed in all the charts, without discovering any appearance of land" ... "I am disposed to believe, that the Isle of Grand also exists, and that my not being able to find it, arose from an error in copying the Latitude given by La Roche … I might, on my return, search for it in the Latitudes of 40° and 41°, having strong reason to believe, that there is land in or near those Latitudes, but to the Eastward of the Longitude which I crossed; as otherwise, I am at a loss to account for such a quantity of birch twigs, sea-weed, drift-wood and birds as were seen in that situation."

to look for Isle Grande as the first objective in his 1793–1794 exploratory voyage but, although his reckoned latitude was correct (Gough is actually centred at 40°19'S), he unfortunately missed the opportunity to find the island: "... we crossed near the supposed situation of the Isle Grande. At this time my vessel was almost a wreck, very short of provisions, and what remained in a very bad state, to which may be added an hurricane of wind and the winter season: circumstances that, I trust, will be a sufficient excuse for my not renewing my search of it as I had intended." In his attempted reconstruction of the 1675 events Burney found a possible place of landing as far west as the coast of

in 1906, was entitled ''South Georgia: Discovered by the Frenchman La Roche in the year 1675''. While Pendleton probably erred regarding La Roché's nationality due to his French last name, British historian Peter Bradley noted: "Despite the suggestion that La Roché was English, the name and the return to La Rochelle … appear to indicate a French connection." Some authors maintain that La Roché was a Spaniard ("… a century before, the Spaniard Antonio de la Roca had discovered Georgia …;" "… the Spanish navigator Antonio de la Roca discovered the South Georgia Islands …") yet provide no supporting evidence.

Sovereignty implications and context

Both the discovery of Roché Island (South Georgia) and the landing on Isle Grande (Gough Island) in 1675 had little if any sovereignty implications, as the islands were not even claimed on that occasion. A sort of antecedent in that respect might have been the territorial delimitation provisions of the
Treaty of Tordesillas The Treaty of Tordesillas, signed in Tordesillas, Spain, on 7 June 1494, and ratified in Setúbal, Portugal, divided the newly discovered lands outside Europe between the Kingdom of Portugal and the Crown of Castile, along a meridian (geography) ...
concluded in 1454 between Portugal and Spain which, if applied, would have left both islands to the former. Portugal, however, never claimed the islands. Neither did Spain, while major European powers of that time like France, England and a newly independent Netherlands denied any wider validity to the inter-Iberian agreement anyway. As King
Francis I of France Francis I (; ; 12 September 1494 – 31 March 1547) was King of France from 1515 until his death in 1547. He was the son of Charles, Count of Angoulême, and Louise of Savoy. He succeeded his first cousin once removed and father-in-law Louis&nbs ...
is quoted to have remarked about the Tordesillas Treaty, "I should like to see the clause in Adam's will that cuts me out of my share in the New World." Claiming would have to wait until 1775 for South Georgia and 1938 for Gough, in both cases by Britain. Another attempt at introducing some bilateral legal arrangements for southernmost South America (roughly Patagonia and Tierra del Fuego) was the 1790
Nootka Sound Convention The Nootka Sound Conventions were a series of three agreements between the Kingdom of Spain and the Kingdom of Great Britain, signed in the 1790s, which averted a war between the two countries over overlapping claims to portions of the Pacific No ...
concluded by Britain and Spain, establishing a sort of regime that granted to the subjects of the two kingdoms equal exclusive rights over the local marine living resources, notably seals, whales and fish; and last but not least, kept third countries out. (The restriction to erect only huts and other temporary structures connected to fishery "shall remain in force only so long as no establishment shall have been formed by the subjects of any other power.")

founded two fortified settlements in the Strait of Magellan, albeit short-lived ones. The Dutch and the French had their own strategic interests in the region and tried to establish effective occupation over certain territories in Chile and the Falklands respectively. In his remarks on the navigation round Cape Horn, Colnett advised for his country to make use of the Nootka Convention and take possession of Staten Island: "Staten Land is well situated as a place of rendezvous both for men of war and merchant ships ... the North side offers the best place for an establishment, if it should ever be in the view of our government to form one there ... If the navigation round Cape Horn should ever become common, such a place we must possess; and agreeable to the last convention with Spain, we are entitled to keep possession of it, and apply it to any purpose of peace or war." By his personal experience, living conditions there were deemed "far preferable to many stations in Norway." As it happened, Britain took over the Falkland Islands instead.
