Launching from the Japanese sub I-25 (like below) Nobuo
Fujita piloted his light aircraft over the state of Oregon near
Brookings and firebombed Mount Emily, starting a forest fire.           

President Franklin D. Roosevelt immediately called for a news
blackout for the sake of morale. No long-term damage was 
done, and Fujita eventually went home to train navy pilots for
the rest of the war.

It was the first-ever aerial bombing on the US mainland.
