Japan conducted a surprise attack at Pearl Harbor, Hawaii on Dec. 7, 1941 that ultimately brought the United States into World War II.

What most people don’t know is that Japan conducted two surprise attacks on the U.S. mainland less than a year later, with the goal of starting wildfires. Now known as the Lookout Air Raids, beginning on Sep. 9, 1942, a Japanese submarine surfaced off the coast of Oregon, assembled a seaplane, and pilot Nobuo Fujita took off toward the Oregon forests.

Here’s what happened next, according to the Los Angeles Times:

At 6:24 a.m. Mr. Howard Gardner, a forestry service observer on Mt. Emily reported seeing an unidentified seaplane come from the west, circle and return toward the sea. He described the plane as a single-motored biplane with a single float and small floats on the wing tips. The plane appeared to be small and of slow speed. It had no lights, no distinct color and no insignia was visible. It is possible that a plane of this type might have been carried on a submarine.

Fortunately, it wasn’t the best time to start a fire since the area was so damp. While Fujita did successfully drop his bombs and start a small fire, it didn’t turn into the hoped-for wildfires that would take valuable resources away from the war effort.

Three weeks later, Fujita gave it another try with two more bombs, and once again, he was unsuccessful.

In his obituary in 1997, The New York Times wrote:

A quiet, humble man who in his later years was deeply ashamed of his air raids on the United States, Mr. Fujita eventually forged a remarkable bond of friendship with the people of Brookings, the small logging town whose surrounding forests he had bombed. Last week, as he lay dying, the town council of Brookings hailed Mr. Fujita an ”ambassador of good will” and proclaimed him an ”honorary citizen” of the town.

His mission was unsuccessful but he was hailed as a hero back in Japan. And Fujita did earn his place in history as the pilot flying the only enemy aircraft that has ever bombed the U.S. mainland.
