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.
