  2. Baker

    Addison Baker led the 93rd Bomb Group. After antiaircraft fire set his B-24 ablaze, he continued toward the target; he died when the aircraft crashed.

  3. Benghazi

    Five B-24 groups assembled near Benghazi in Libya. Three came from, or were intended for, Britain; two were already serving in the Mediterranean.

    Did you know?

    Crews repeatedly bombed a desert mock-up of the refinery targets before flying the mission.

  6. Low Level

    The B-24s approached and bombed at very low altitude. Navigational errors and alerted defenses undermined the planned surprise, exposing the aircraft to intense ground fire.

  7. Medal of Honor

    Five participants received the Medal of Honor for actions during the raid. Baker, John Jerstad and Lloyd Hughes received their awards posthumously.

  9. Oil Fields

    Ploesti’s oilfields were a source of crude oil for Germany. The August raid targeted the region’s refinery complex, where that crude oil was processed.

  10. Oil Refinery

    An industrial plant that processes crude oil into fuels and other products.

    The raid damaged refineries, but repairs restored production. German authorities used forced laborers to repair the complex.

  11. Petroleum

    Naturally occurring oil from the earth.

    Romanian petroleum supplied Germany’s war effort. The Allies hoped that attacking Ploesti would reduce that fuel supply, linking the raid to the wider war.

  12. Ploesti

    Ploesti lay north of Bucharest. The raid killed airmen and people on the ground; Romanian civilians and officials buried American dead at Bolovan Cemetery.
