That night, Luftwaffe bombers diverted to the Ukrainian base from a route to a nearby railroad target 128 Lancasters, 6 Mosquitoes, and 5 Lancasters attacked the Wesseling synthetic-oil plant in 10/10ths low cloud using H2S radar (production loss was 40%).
Chemische Fabrik Wesseling AG operated a Wesseling facility, and to replace Wesseling, in April 1944 a "large underground plant for synthetic oil manufactured from brown coal was started outside Bergheim".
In addition to the nearby Oppau plants, Ludwigshafen targets included a small synthetic oil plant and an oil refinery that used the dehydrogenation process to improve "gasoline quality". Wurster of the Ludwigshafen Military Government was the "managing director of Oppau and Ludwigshafen.""To reduce output … It meant the end of German armaments production" (Speer).
"Before that he was, at least from his standpoint, committing absurdities" (Speer, December 1, 1944) Mission 376: 105 B-17s bombed an oil dump at Königsburg/Magdeburg.A Königsberg target was also bombed on June 20 (Mission 425), and Magdeburg also had a Junkers Jumo 211 engine plant (the 487 BG bombed the Magdeburg airplane factory on August 5, 1944.) Mission 376: 55 B-17s bombed oil industry at Magdeburg/Rothensee.Bohlen-Rotha, Magdeburg-Rothensee, Ruhland-Scwarzheide (a 1937 Fischer-Tropsch plant), & Zeitz-Troglitz were the 4 plants (3 were for Bergius hydrogenation) of Braunkohlen Benzin AG (Brabag), which was formed on October 26, 1934.The intelligence annex to the field order for the May 31 Ploieşti mission stated "Successful attacks on [the aircraft factories at the] Wiener-Neustadter complex have raised oil to high priority.Destruction of vital installations in targets selected will immobilize Ploesti capacity for several months."A May 5 decoded message stated anti-aircraft artillery was being moved to Pölitz and Blechhammer, and one on June 5 indicated the Luftwaffe was short of fuel.
British intelligence concluded that the bombing of oil targets would be "crippling" in 3–6 months. Additional B-17s, including some Soviet-based for Operation Frantic, attacked the Galaţi Airdrome: "most oil from Ploesti must be shipped west over [the] Danube for refining." (annex of intelligence report) of Neuengamme provided forced labor.At his HQ company Christmas party, Erwin Rommel received a miniature oil drum as a gift (containing captured British coffee). However, "even if the whole of the Romanian production were knocked out early in the year, [Germany] would still have enough for operations in 1944 [but the destruction of] two tetraethyllead factories…After Hap Arnold created the United States Army Air Forces Committee for Operations Analysis (COA) on December 9, 1942, to develop a plan for strategic bombing, the COA's initial Western Axis Oil Industry report listed the following order of strategic importance: hydrogenation facilities (15 plants), refineries (29 plants), lubrication plants, coker units, Fischer-Tropsch facilities, tetraethyllead facilities, and oilfields/pipelines. would hamstring the production of German aviation fuel" (Brehon Somervell).On June 6 the plan was deemed "an important and desirable operation", and the "Planning committee" first met on June 25 (Uzal Girard Ent predicted losses of 75 aircraft). Operation Tidal Wave bombed the Astra Română, Columbia Aquila, and Unirea Orion refineries at Ploieşti (four Medals of Honor were awarded for the US Bomber pilots and four Order of Bravery to the Bulgarian fighter pilots to shoot them down) Operation Tidal Wave bombed the Astra Română and Concordia Vega refineries at Ploieşti (one Medal of Honor was awarded).The Enemy Oil Committee subsequently appraised that Operation Tidal Wave bomb damage at Ploieşti caused "no curtailment of overall product output".96 of 328 B-17s bombed 238 tons on the "Hydrier Werke Scholven A.…destruction of remaining active capacity of Ploesti will create [a] critical situation for [the] entire Axis war effort and make possible further important inroads through attacks in Austria, Hungary, Yugoslavia and Italy.
