Fort Stevens

About this property

Fort Stevens was an American military installation that guarded the mouth of the Columbia River in the state of Oregon. Built near the end of the American Civil War, it was named for Civil War general and former Washington Territory governor Isaac I. Stevens. The fort was an active military reservation from 1863–1947. It is now listed on the National Register of Historic Places. Today the site is an Oregon state park just northwest of Warrenton. The fort was constructed in 1863-64 during the Civil War as an earthwork battery on the south shore of the mouth of the Columbia River, and was known as the Fort at Point Adams. It was later renamed as Fort Stevens in 1865, in honor of the former territorial governor of Washington, Isaac Stevens, who had been killed in action at the Battle of Chantilly during the American Civil War. Fort Stevens was the primary military installation in what became the "Three Fort Harbor Defense System" at the mouth of the Columbia River. The other forts were the Post at Cape Disappointment, later Fort Cape Disappointment and later Fort Canby, built at the same time as Fort Stevens, and Fort Columbia, built between 1896 and 1904. Both are on the Washington side of the river. The fort was meant to defend the mouth of the Columbia from potential British attack during the Pig War of 1859 and subsequent ongoing regional tensions through 1870 in the San Juan Islands, and was important during the 1896–1903 Alaska Boundary Dispute, when British-American tensions again were high and the two countries were on the brink of war. In 1906, the crew of the sailing ship Peter Iredale took refuge at Fort Stevens, after she ran aground on Clatsop Spit. The wreck is visible today, within the boundaries of Fort Stevens State Park. After World War I, the U.S. Navy established a radio station at Fort Stevens for communication with the fleet. Additionally, in 1932 the Navy co-located a secret radio intercept station at Fort Stevens to listen in on Japanese Navy coded messages. Specially trained radiomen from the "On-the-Roof-Gang" were stationed at the listening post. The station was designated "S" because of the Fort Stevens location. It was designated to be restored as a historical monument by the federal government in 1936. In September 1939, the U.S. Navy relocated Station S to Fort Ward on Bainbridge Island, Washington because of better intercept conditions. On the night of June 21–22, 1942, the Japanese submarine I-25 surfaced off Fort Stevens and fired 17 shells 14 cm-caliber deck gun, making Fort Stevens the first military installation in the contiguous United States to come under enemy fire in World War II. The Japanese attack caused no damage to the fort itself, only destroying the backstop of the post's baseball field.
