The importance of the Columbia River in the Pacific Northwest was made apparent during the Civil War. Forts were built to protect the North against an English invasion from Canada should the British join the Civil War on the Confederate side. There had been Cape Disappointment on the Washington side of the Columbia to protect the mouth of the Columbia River. In 1865 Fort Stevens complete with a moat and drawbridge was established on the Oregon side on Point Adams west of Astoria. It was named for General Isaac Stevens, a former Governor of Washington Territory. Stevens was killed in 1862 leading a New York regiment against the Confederates.
