21 Jun 1942

United States
  • Japanese submarine I-25 approached close to the Oregon shoreline, careful to avoid any minefields by following some fishing boats. I-25 arrived within 1,100 yards of the mouth of the Columbia River. Intending to shoot over the Clatsop Spit and shell the Navy’s Tongue Point seaplane base at Astoria, Oregon, I-25 fired 17 rounds from her deck gun, but the shells fell well short and landed in undeveloped areas of Fort Stevens. This was Japan’s second and last naval bombardment of the continental United States during World War II. [Apparently, I-25's navigator was relying on an antiquated map of the area which showed a submarine and destroyer base on Tongue Point. Such a base was completed in 1924, but never used. In 1942, the military presence on Tongue Point was as a Navy seaplane base servicing a squadron of PBY Catalina patrol planes.] ww2dbase [Japanese Attacks on the Continental United States | Warrenton, Oregon | CPC]
