 Regardless of the efforts of Stuart and others, the Pacific Fur Company soon collapsed due to the War of 1812, with Fort Astoria being sold to the North West Company in 1813.Later on, the Hudson's Bay Company tried to discourage American trappers from operating in the Pacific Northwest, establishing an overland route between Fort Astoria and the York Factory on Hudson Bay called the York Factory Express.The route was partially based on the paths explored by Stuart.
