American fur trader John Jacob Astor built Fort Astoria on the Columbia River in 1811. Under pressure brought by the War of 1812 Astor sold the fort in 1813 to what would become The British Hudson's Bay Company. In 1830 Hudson Bay Co. built a new Fort Vancouver slightly up the Columbia River in the future Washington state. This fort was the main supply depot for Hudson Bay forts in all the Pacific Northwest. Within a few years they were growing quantities of wheat, constructed saw and flour mills, and yearly shipped lumber to the Hawaiian Islands and flour to Sitka, Alaska. They were resupplied every year by two to three ships that brought trading supplies around Cape Horn from England.
