out to be incorrect. For one thing, after the Second Raid on Schweinfurt the Nazis re-engineered many machines to use other methods of friction reduction. Casablanca and Pointblank "Casablanca" and "Pointblank" were guidelines for the EOU in identifying priority targets. The Casablanca guidelines were used to select five categories of target: Kriegsmarine, the German navy Luftwaffe, German air force Transportation, such as the Reichsbahn Oil Any other targets vital to the economy The EOU proceeded to apply their methods within each category and try to choose the best targets. One point that this group underestimated was the effectiveness of bombing German oil refineries: they had correctly estimated the amount of stocks kept but failed to account for the methods the Germans would employ in the short term to conserve oil supplies. The later oil campaign of World War II is thought by many historians to be a substantial factor in Nazi defeat. As the war progressed, however, there was a call for a new plan, Pointblank directive. This plan set aside the five points from the Casablanca plan and instructed the EOU to target the German air force primarily, as this force was doing the most damage to the allies. The EOU proved to be a vital tool to the Allies’ air forces and helped them defeat the Germans in World War II.
