The United States and England went to war in 1812. In 1813 a British warship sailed into the Columbia River to capture the post and take control of the fur trade. Astor’s fur traders beat them to the punch by selling the post to the British NorthWest Company. From 1813 to 1818, the British owned Astoria and it was known as Fort George. In 1818, a treaty with England established joint occupation of the Oregon Country, as it was called then. The boundary was set at the 49th Parallel. The British did not completely abandon Astoria until 1846.
