This was a daylight raid on Marifu Railroad Yards on Honshu. No opposition was encountered.
The last mission of World War II was flown on
the night of 14 August. Sixth ships flew to the Marifu
railroad yards at Iwakuni on Honshu. Forty-two planes took
off at 0619 with bomb bays loaded with 500 pound general
purpose bombs. One ship returned early and two bombed the
town of Sanagoseki. No enemy opposition of any nature was
encountered. All radio operators were briefed to listen for a
coded message indicating the war had ended which meant all
airplanes were to return to their base. The message,
"Break Utah Utah Utah Break" did not come, and the
mission was carried out as planned.
