In what became the second attack on a continental American military installation during World War II, the , under the command of Tagami Meiji, surfaced near the mouth of the Columbia River in Oregon on the night of June 21 and June 22, 1942, and fired shells toward Fort Stevens. The only damage officially recorded was to a baseball field's backstop. Probably the most significant damage was a shell that damaged some large phone cables. The Fort Stevens gunners were refused permission to return fire for fear of revealing the guns' location and/or range limitations to the sub. American aircraft on training flights spotted the submarine, which was subsequently attacked by a US bomber, but escaped.
