This was a night incendiary mission involving 35 aircraft from the 6th Bomb Group:
Target for the 1 July mission was Ube, located on Honshu about fifteen miles east of Shimonoseki. Thirty-nine airplanes were airborne with a bomb load of 1399 one hundred pound incendiaries. Two ships lost an engine soon after takeoff and were forced to jettison their bombs and become early returns. The thirty-seven others bombed the primary target and striking clusters burned out 1.8 sq mi of the built-up area. The Japs offered little defense – four fighters were sighted but none attacked the formations.
