The movement leading to the first voyage to Hudson Bay by Gillam and his company was carefully watched by the French Government. In February, 1668, at which time Gillam's expedition had not yet sailed, the Marquis de Denonville, Governor of Canada, appointed an officer to go in search of the most advantageous posts and occupy the shores of the Baie du Nord and the embouchures of the rivers that enter therein. Among other things the governor gave orders "to arrest especially the said Radisson and his adherents wherever they may be found." Intendant Talon, in 1670, sent home word to M. Colbert that ships had been seen near Hudson Bay, and that it was likely that they were English, and were "under the guidance of a man des Grozeliers, formerly an inhabitant of Canada." The alarm caused the French by the movements of the English adventurers was no doubt increased by the belief that Hudson Bay was included in French territory. The question of what constituted ownership or priority of claim was at this time a very difficult one among the nations. Whether mere discovery or temporary occupation could give the right of ownership was much questioned. Colonization would certainly be admitted to do so, provided there had been founded "certain establishments." But the claim of France upon Hudson Bay would appear to have been on the mere ground of the Hudson Bay region being contiguous or neighbouring territory to that held by the French. The first claim made by France was under the commission, as Viceroy to Canada, given in 1540 by the French King to Sieur de Roberval, which no doubt covered the region about Hudson Bay, though not specifying it. In 1598 Lescarbot states that the commission given to De La Roche contained the following: "New France has for its boundaries on the west the Pacific Ocean within the Tropic of Cancer; on the south the islands of the Atlantic towards Cuba and Hispaniola; on the east, the Northern Sea which washes its shores, embracing in the north the land called Unknown toward the Frozen Sea, up to the Arctic Pole." The sturdy common sense of Anglo-Saxon England refused to be bound by the contention that a region admittedly "Unknown" could be held on a mere formal claim. The English pointed out that one of their expeditions under Henry Hudson in 1610 had actually discovered the Bay and given it its name; that Sir Thomas Button immediately thereafter had visited the west side of the Bay and given it the name of New Wales; that Captain James had, about a score of years after Hudson, gone to the part of the Bay which continued to bear his name, and that Captain Fox had in the same year reached the west side of the Bay. This claim of discovery was opposed to the fanciful claims made by France. The strength of the English contention, now enforced by actual occupation and the erection of Charles Fort, made it necessary to obtain some new basis of objection to the claim of England.
