Fur trapper James Sinclair, on orders from Sir George Simpson, Governor of the Hudson's Bay Company, led some 200 settlers from the Red River Colony west in 1841 to settle on Hudson Bay Company farms near Fort Vancouver. The party crossed the Rockies into the Columbia Valley, near present-day Radium Hot Springs, British Columbia, then traveled south-west down the Kootenai River and Columbia River. Despite such efforts, Britain eventually ceded all claims to land south of the 49th parallel to the United States in the Oregon Treaty on June 15, 1846.
