Armed with practically unlimited powers over an unlimited area, the company lost little time in sending out ships and establishing factories. In addition to Fort Rupert at the south-eastern end of James Bay, Fort Hayes, or Moose Fort, was constructed at the south-western end of the bay, at the mouth of the Moose river; and some distance to the north of the latter fort, Fort Albany was placed at the outlet of the Albany river. Voyages were also made to the mouth of the Nelson river, on the western shore of Hudson Bay, but no attempt was made to plant a factory there till the year 1682. [Sidenote: _Collision between French and English in Hudson Bay._] [Sidenote: _A Canadian company formed._] It was in that year and at Fort Nelson, as it was called, that French and English first came into collision in the far North. Radisson and Des Groseilliers, who had taken service with the English in consequence of being fined by the Governor of Canada for making their early journeys without his licence, subsequently returned to Canada, and piloted their countrymen by sea into Hudson Bay. A company was formed in Canada in 1682, the Compagnie du Nord, and sent out an expedition from Quebec with these two men on board. They reached the Nelson river; a few days before they arrived a Boston vessel appeared on the scene, and a few days subsequently a vessel came from England, sent by the Hudson Bay Company to build a fort. After a short interval the French overpowered the English; but two years later, in 1684, Radisson and Des Groseilliers having in the meantime again come back to the Hudson Bay Company, that company recovered its fort, and the French lost their footing on Hudson Bay. {188} [Sidenote: _Attack made overland from Canada on the English forts on Hudson Bay._]
