Nazi oil goes up in smoke.

Nazi oil goes up in smoke. Clouds of black smoke coupled with flame almost obliterate the target areas at the Olweke Schinoler, Ernest Schliemann, Deutsche Petroleum and the Hamburg refineries at Hamburg, as Eighth U.S. Air Force Liberators and Fortresses press home a heavy attack June 20, 1944. Other targets struck by the American raiders on the same day, when they delivered the heaviest blow of the war against German oil production, were other synthetic oil plants at Magdeburg and Ostermoor.
