Fort Stevens (Hammond, Oregon, Oregon)

Hammond, Oregon · Oregon · Civil War, World War II

Quick BriefFort Stevens was constructed in 1863–64 as an earthwork battery at Point Adams on the Columbia River's south shore, initially called Fort at Point Adams before being renamed in 1865 to honor former Washington Territory Governor Isaac I. Stevens, who was killed at the Battle of Chantilly. In June 1942, Japanese submarine I-25 fired 17 shells at the fort—the only attack on a continental U.S. military installation during World War II—though no significant damage resulted.

History & Significance

Fort Stevens was one of three forts authorized by Congress in February 1862 to defend the mouth of the Columbia River in Oregon and Washington Territory. The fort was designed to protect the river from Confederate commerce raiders, though the Civil War concluded before its completion.

The installation remained active from 1863 to 1947. Modernization began in the mid-1890s with a main gun line, new garrison buildings, and a mine depot.

On June 21–22, 1942, Japanese submarine I-25 surfaced off Fort Stevens and fired 17 shells, making it the first military installation in the contiguous United States to come under enemy fire in World War II. The attack caused minimal damage, destroying only a baseball field backstop.

After decommissioning in 1947, the grounds were transferred to the U.S. Army Corps of Engineers and later to the Oregon Parks and Recreation Department in 1975. Much of the fort is now preserved within Fort Stevens State Park, part of the Lewis and Clark National Historical Park, encompassing 3,700 acres with camping, beaches, trails, and a military history museum.
